If (some) recruiters sold coffee … Being a developer in 2018 means being assaulted by hundreds of messages offering “amazing job opportunities”. Unfortunately, it is usually difficult to assess if the “amazing opportunities” are really worth your time. The sad truth Fact is, you are still approached by tons of recruiters who often have no technical background. To me, this just feels like — for 2 reasons. a waste of time First, how is a non-technical person supposed to explain and discuss complex technological challenges, and inspire you? Secondly, without technical background, . it is nearly impossible to make sure that you are technically up to the challenge A common Rant on devRant.com “Let’s ask the most crucial stuff at the end, this way we waste time” … … said no one ever. And still, contrary to logic, both of the crucial steps of the recruitment process usually happen only at the end — during the technical interview. Until someone can concretely explain the tech challenges you need to wait for the technical interview. And the same goes for your skills. Only the discussion with the technical manager will confirm your capacities match the companies needs. This means that the essential information needed for a decision is only discovered at the end. Why?! Improve quality instead of quantity Employers are complaining about how difficult it is to attract tech talent and they usually blame the market, which is a solid argument. There’s surely a lack of tech talent and an overload of recruiters & headhunters. However, I doubt hiring more of the latter will change anything. It’s like hiring more sales people when the product is s — t. It just doesn’t solve the root problem. If companies are trying to attract instead of frustrating you, they should have a look at their approach. Us vs. Them Sociological theories explain that “the larger the size of an out-group, the more the corresponding in-group perceives it to threaten its own interests, resulting in the in-group members having more negative attitudes toward the out-group.” In our context, it is clear that tech people belong to the in-group, while recruiters belong to the out-group. And by doing a quick google search, it becomes obvious that the “negative attitudes toward the out-group (recruiters)” is not a myth. Now, considering the two groups, there are two ways to explain an opportunity. From the out-group (recruiter) perspective it would look something like this: “Hi Dev, I have a nice opportunity for you. The salary range is x — y €. Our company has great programs to grow and learn new technologies. Many of our developers use some hours per week to further educate themselves. We are working on this problem and our tech team is trying to solve it by using [CODING LANGUAGE KEYWORDS]. And they also use the agile methodology. Our tech team is really great, they are working really efficient and they are pretty intelligent.” And from the in-group perspective: “Hi Dev, My Team and I are currently trying to solve this problem and we need someone with your skills to help us further develop the [TECH JARGON]. We’ve already [TECH JARGON] and [TECH TECH], and now it’s time to [TECH JARGON]. My HR manger let me know that you look for a place to grow and learn. From my own experience I can tell you that we are allowed to allocate some hours per week for self-development. I started to learn Golang this year, so I take 4 hours per week to focus on that. Oh and by the way, the Tech Team compensation here at company3000 are really nice. For your experience the range usually is x — y €.” If you feel more likely to reply to message number 2, you’ll agree: when contacted by an in-group member, by nature, we feel more comfortable. Partly because peers speak the same language, make the same jokes and understand our pains. Reduce frustration and stop wasting time Next to being more likely to catch the attention of IT talent, another benefit of involving IT Teams from the start is better efficiency — and . On average IT Teams need 50% less interviews to hire a developer. studies confirm it The reasons for this are pretty straight forward and have mostly been covered in this post, but here we go again: During a technical interview, the discussion is about the inspiring part. What you are going to create, how you’re is going to master the challenge, and why you’ll succeed. While HR managers drive the recruitment processes (search & selection), it should be CTOs and Tech Leads who contact candidates directly. They should be the first touch point to screened and selected candidates. This way high quality messages are ensured, because candidates can immediately talk about what inspires them: the tech they will work on.

Python is a universally accepted programming language for web and application development. Globally, entrepreneurs can get dynamic business applications and seamless websites using Python. But, choosing the right Python web development services provider is like finding a needle in a haystack. Here is a step-by-step guide to hiring the most suitable Python web development company for your upcoming project. Python is a robust object-oriented, general-purpose language with dynamic semantics. Today, Python powers the websites of some of the leading companies in the world including Facebook, Netflix, Spotify, and Instagram. Another report has revealed that 1.4% of all websites on the internet use Python as a server-side programming language. A Github survey has given the second rank to Python in the top-using programming languages in the year 2021. All these stats show the growing importance of Python in web and application development domains. You can make the most of this robust and powerful language by hiring Python experts. Before moving to the top tips to hire the right development partner from various Python development companies, let’s discuss the initial points to consider for your new web or application development project. What to Keep in Mind before Selecting a Python Development Company? Python can be used to develop a wide range of web and mobile app solutions. Therefore, it is imperative for you to define your requirements clearly. Once you make a roadmap for your upcoming project, you can easily explain your idea to Python consultants or experts. If your requirements are properly defined, you can find the right team to meet these requirements effectively. Also, when you hire Python developers for your project, you need to define minimum professional requirements for your team. The best python development teams can Use Python libraries properly Meet software development challenges effectively Offer a transparent working process Send reports regularly Communicate well as and when necessary Complete the project on time It is better to take an interview of shortlisted candidates of a reputed Python web development company. You can check whether these candidates meet all or some of these key requirements. Communication skills, interactions, understanding, experiences, and skills are the most important factors to consider. Let’s go through the useful steps to shortlist the Python development companies. How to Shortlist Python Web Development Companies? As per a study, around 22 million Python developers are active across the world, it is difficult to find good Python/Django developers. You can take the help of Google or reputed review and research sites like and to shortlist the top Python web development companies. It remains cost-effective to outsource your web or app development projects to reputed Python outsourcing development companies. Nexten.io Clutch GoodFirms Here is how you can find the right Python development partner. Study Their Portfolio : Every software development company has a rich portfolio. Most companies have case studies and portfolios on their websites. The portfolio shows the developer’s hands-on experience and skills to build customized solutions similar to your project. You can also find whether the team is an expert in Django. Case studies elaborate on the issues and their solutions so that you can get an idea of the company’s development approach and attitude toward the clients. You can also ask for portfolios in PDF form from reputed Python development companies. Read Testimonials From Their Clients: Top Python web development services providers can successfully accomplish projects. They get the client’s feedback or testimonials as well. These testimonials are the best way to know whether the Python web development company is capable of meeting your project requirements. If the company has met the expectations of previous clients in terms of communication, project management, product development, and collaboration, then you can expect that it will deliver optimum results. You can get the past client’s feedback on various platforms including Upwork, GoodFirms, and Clutch. All you need to do is to go to the company’s profile. You can also meet a few of the company’s past clients if the company is willing to share their information. This one-on-one meeting can give useful information about the company’s way of dealing with challenges and accomplishing projects on time. Interview Developers: When you hire Python developers for your project, you need to ensure that they are capable of addressing development challenges, project needs, and market trends. You can interview Python/Django developers to build a team. If you have limited technical knowledge, you can take the help of Python experts for making a questionnaire. They can assist you to include questions related to roadblocks you may face during the development process. It is possible that you ask developers technical questions, and they ask you questions related to your project. Therefore, you need to give a proper job description to every developer related to the project and their specific roles in it. It is necessary to find out whether the Python web development company has a genuine interest in your project, and if it can complete the project on time. You can contact Python consultants to get insights into necessary features and functionality as per your roadmap. Python consultants can also create a list of technologies and APIs necessary for your project, and you can ask questions related to these technologies to candidates. Finally, while interviewing Python developers, you need to check their communication skills and other soft skills. Review Technology Stack: This is another major aspect to keep in mind. Every software development company uses the technology stack to build software. Python web development companies are using multiple stacks because Python is a versatile programming language and enables developers to build scalable solutions. Python is a mature language and capable of automating many tasks in modern enterprises. This language also supports futuristic technologies like AI and Blockchain, and therefore, you can ask for technology stacks the development companies use. Companies with good experience in developing Python solutions can work with a wide range of technology stacks. Developers of such companies have expertise in various libraries, APIs, and extensions. What’s more, every programming language has specific standards. It is beneficial to inquire whether development companies follow these standards. The official have all such standards. Python Guidelines As mentioned above, Python is an object-oriented language, and therefore, developers need to follow principles that support such language. Such principles are known as SOLID that stands for Single responsibility, Open/Closes, Liskov substitution, Interface Segregation, and Dependency inversion. SOLID principles are designed to write stable and scalable code. It is possible to understand and reuse the Python code easily if it is written on the basis of SOLID principles. Request Quotes: Advancing web and app development technology has reduced the development time and cost significantly. These days, SMEs and even startups can also come up with innovative and user-friendly solutions in a cost-effective way. However, it is necessary to hire dedicated Python developers from regions where the hourly rates are reasonable. For example, countries like Ukraine, Argentina, Poland, and Ukraine have an , whereas the same in the hourly rate in the range of $25-50 USA is $100-$200. You can request a quote from Python development companies to know how much your software will cost. Reputed and reliable development companies can estimate the number of hours more accurately for developing web solutions with desired features. However, you need to contact them with the list of features you want to include. If you have a requirement document ready, you can easily get quotes from various software development companies. If you do not have this list ready, you can consult Python experts for the same, but then, you may have to pay for it. Another important factor is, usually, development companies keep the support and maintenance costs separately in the quote. However, you need to ensure that software testing cost is included in the quote because testing is an integral part of the development process. You can hire Python experts by choosing any of three engagement models: Fixed Price, Time & Materials (T&M), and Milestone. Your quote will be varied based on the hiring model. Also, you should ask for payment options and other formalities before hiring developers for your project. You can consider all these points for shortlisting . Let’s go through quick points that differentiate good and bad software development teams. Python development companies Qualities You Should Look for in a Software Development Team These days, you have numerous options available for availing Python web and app development services. The following characteristics of a good software development team can assist you in selection. An Ideal team of Python Developers Follows all standard practices and Python guidelines Has hands-on experience in using Python libraries Has a full understanding of object-oriented programming Has necessary insights into development trends and technological advancements Works transparently Can communicate well and gives reports regularly Works professionally and resolves issues with proper coordination Can solve development problems related to Python architecture Can provide code samples as and whenever asked Is ready to complete a test task as a part of the interview process These points will help you find the right team of developers for your project. Apart from these qualities, the right team of developers is willing to sign contracts like a software development agreement or NDA (Non-Disclosure Agreement) with you to protect your rights, confidential data, and business ideas. Finally, we will dig deep into the Do’s and Don’ts while hiring Python developers or a Python/Django development company. Do’s and Don’ts for Hiring Python Experts Do’s Check the portfolio of their companies to know what they do and how they work Read the blog of companies to get an idea about their expertise and goals Go through the social media presence and individual developer’s profile on LinkedIn Read client reviews or feedback from clients on various marketplaces like Clutch and platforms like LinkedIn Write an email with requirements and study the development company’s response Schedule a call for a meeting or demo in case of a ready-made software Check the company’s presence on Dribble or Behance to learn about their UI design capabilities Find out what the Python development company offers for your software project and get valuable insights from different shortlisted companies Arrange an interview with shortlisted developers to know their technical expertise and soft skills Ask developers whether they have worked on similar projects and are willing to meet the challenges of your project Get the idea of their Python/Django knowledge and capability to integrate advancements of emerging technologies Don’ts Don’t fall prey to cheap development costs because you may have to compromise on the quality of software Never trust claims that a team can use any technology, as its members have experience in every technology Don’t hire a company or a team that remains hesitant to jump on a voice or video call because it may mean that they are not much confident or not interested in working on your project Never hire a Django or Python development company that works on your project like other projects without considering your goals and business model Don’t hire Python developers who have a track record of including irrelevant features in the client’s projects. You can get this idea from the past client’s testimonials or feedback. Never trust a development company that has an impression of accepting multiple projects at once and then leaving some projects unfinished. Web or app development projects have equal importance as your other projects because it can take your company to a new level. Therefore, it is necessary to set goals and select the Python development company that can assist you to achieve these goals with seamless and user-friendly software Wrapping UP Finding and selecting the most suitable Python web development company are herculean tasks. However, if you proceed with a requirement list and focus on every detail, you can easily find the best development partner for your upcoming project. Here we have included qualities of a good development team and Python developers to assist you to select the right team. There is no exaggeration in mentioning that choosing an ideal Python development company is like recruiting new talents. You can expect a positive outcome if your project goals are clearly defined and the roadmap for software development is ready.

Why You Should Choose Python Development for Your Next Web Project

A couple of months ago, I had a need to make a lift table control. Initially, I wanted to use metal buttons with a backlight. But then I think that 8 buttons would look very ugly. And I got the idea to make control using the Nextion display. I had a 2.4” screen with a resolution of 320x240 (NX3224T024). Its size was ideal for mounting in a table. After reading about the possibilities of the screen, a lot of ideas for the user interface were born in my head. Among these ideas was support for multilanguage. I planned to connect the screen to the Arduino Mega 2560. To work with their screens, Nextion made a library for Arduino, which is available on their official website and on GitHUB Unfortunately, the Nextion editor does not have full support for string arrays, so I had to think about how to implement language selection and store "language packs" in a convenient way. So that you can quickly read, change or create a new “language pack” in your project. As a result, I came up with the following option: On the main page, I created a global variable that has the value ID of the currently selected language. cur_lang_id Unfortunately, the NX3224T024 screens do not have an EEPROM, so we will store the selected language in the Arduino's EEPROM. The NEXTION library for Arduino only allows you to access global variables that are on the current page, so when you turn on the Arduino, it will load the selected language ID from the EEPROM and pass it to the Nextion display. Nextion display will use the value of this variable for its work. Then I learned that pages in Nextion can be accessed as an array , where n is the ordinal ID of the page. p[n] I decided that the best solution would be to create a page with text elements for each language. Each text object in Nextion has an “ ” attribute that can be used to access it and a “ ” attribute that will store the translation of the word. objname txt After creating the language pages, we can access their values like this: b4.txt=lang_en.Back.txt or this: b4.txt=p[3].Back.txt and like this: home.cur_lang_id.val = 3
b4.txt=p[home.cur_lang_id.val].Back.txt Now, when changing the value in the global variable , the text will change on all pages. The language page ID will change, and the language will change accordingly. home.cur_lang_id.val You can implement the process of changing the language using the code in Nextion. To do this, we set the value of the global variable in the Touch Press Event. home.cur_lang_id.val It remains to write code for Arduino to save the selected language in EEPROM and load it after a power failure. In order for the Nextion display to send information about pressing a button to the Arduino board, we need to check the “Send component ID” checkbox on the Touch Release Event of each button The cur_lang_id global variable is on the page (ID 0), and the choice of languages is on the page (ID 7), when you click on the language selection button, Arduino will not be able to immediately read the changed value. To do this, you first need to open the home page. home lang_select home.cur_lang_id.val This is very inconvenient for the user. You can hang an event on each language selection button, and set ID language in each event. But in this case, if the language page ID changes in Nextion, then the Arduino code will also have to be rewritten. This is inconvenient for us. Therefore, we will create another variable on the page and write the language ID to it too, so that when the button is pressed, Arduino can read the selected language ID. cur_lang_id lang_select Then the Arduino code would look like this: #include <Nextion.h>
#include <EEPROM.h>

byte currentLanguageId = 0;
 
NexPage homePage = NexPage(0, 0, "home");
NexButton english_b = NexButton(7, 2, "b0");	//Button Enlish language
NexButton deutsch_b = NexButton(7, 3, "b1");	//Button Deutsch language
NexButton kazakh_b = NexButton(7, 4, "b2");		//Button Kazakh language

In this article, we will explore the basics of setting up an extension and how to use Flutter in it. has become a very popular choice for mobile developers; its style of UI code and the fact that it renders the same on both platforms makes it a strong choice. One of the limitations Flutter did have was with iOS app extensions. Flutter If you are not aware, are a way for you to “extend” your functionality outside of your own app and allow users to interact with it through other apps on their devices. This could be the browser, notes app, or pretty much any other app. One problem with Flutter was that you would still need to develop the functionality and the UI of your extension using native code while the majority of your app was in Flutter code. This may not be a problem for some of us, but I think we can all admit that it is annoying to still have to maintain this native code. iOS app extensions Well, Flutter 3.16 changed all this, and you can now have your extension UI built with Flutter! What we will be building Our goal in this article will be rather simple: Users will select some text from anywhere on their device and share it Our app should be displayed in the list of choices in the share sheet the OS shows When the user selects our app, they should be shown a simple screen that displays the text they selected Adding a Share Extension to your Flutter app Alright, so this part is the same whether you were using Flutter or just plain iOS, so I won’t go into too much detail but just cover the overall steps you need to take: Open the file from inside your folder. This should launch Xcode. Use from Xcode’s menu, and you should be presented with something like this: Runner.xcworkspace PROJECT/ios File -> New -> Target Either find or search for and press next. Share Extension Set the product name to what you want the extension to be called and press “Finish.” After this point, you should see a new target in Xcode. Xcode will generate some boilerplate for your extension, and at this point, you should be able to test it out by running it in a simulator (or device) and trying to share something. A few gotchas If you see an error similar to when running your app navigate to your main target’s build phases and make sure the step is immediately after the step. Error (Xcode): Cycle inside Runner Embed Foundation Extensions Copy Bundle Resources If Xcode prompts you to “Activate” your extension after you create it, opt in to activate it. Opting out can result in errors that are unclear. Using Flutter UI in the iOS app extension Now that we have our extension boilerplate setup, we need to make it use Flutter for its UI instead of the Storyboard that it currently uses. First, we need to copy the Flutter framework into our extension. If you navigate to you will find a package. Copy this into the frameworks for your extension in Xcode, and make sure that the option is set to . FLUTTER_SDK_LOCATION/bin/cache/artifacts/engine/ios/extension_safe Flutter.xcframework Embed Embed & Sign Now modify the file for your extension to look similar to: info.plist tells the OS which class to use as the root UI controller for this extension. It uses the format . Note that by default there should be an entry for the main storyboard file, you will need to remove that entry to make this work. NSExtensionPrincipalClass ExtensionName.ClassName informs the OS about when this extension should be included in the share sheet. Setting it to the string makes it always be included, but you can filter this further to only be included for specific types (for example, images only). To learn more about how to configure this, visit the . NSExtensionActivationRule TRUEPREDICATE official documentation Configuring the View Controller to use Flutter Now let’s modify our to not use the boilerplate code and use Flutter instead. Replace all of its contents with this: ShareViewController import UIKit
import Flutter
import UniformTypeIdentifiers

class ShareViewController: UIViewController {
    override func viewDidLoad() {
         super.viewDidLoad()
         showFlutter()
     }

     func showFlutter() {
         let flutterViewController = FlutterViewController(
            project: nil, 
            initialRoute: "/share", 
            nibName: nil, 
            bundle: nil
          )         
         addChild(flutterViewController)
         view.addSubview(flutterViewController.view)
         flutterViewController.view.frame = view.bounds
     }
} is now a simple that loads a as its child. The property let’s us configure what route the Flutter app should open on launch, without this it would default to whatever the home or main route you have configured for your app. ShareViewController UIViewController FlutterViewController initialRoute Now let's modify our Flutter app to account for this and modify the main function to return something similar to this: return MaterialApp(
  // ...
  routes: {
    '/': (context) => const MyHomePage(title: 'Flutter Demo Home Page'),
    "/share": (_) => const ShareWidget(),
  },
); I have omitted the boilerplate that Flutter adds during app creation, but we added a route for the /share route that we configured on the Swift side of things. This will make sure that when the extension launches the Flutter engine, the user sees our share widget instead of the app's landing screen. For now, our share widget is a simple Widget with some text in the center. import 'package:flutter/material.dart';

class ShareWidget extends StatefulWidget {
  const ShareWidget({super.key});

  @override
  State<ShareWidget> createState() => _ShareWidgetState();
}

class _ShareWidgetState extends State<ShareWidget> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Text("Hello!"),
      ),
    );
  }
} Displaying the text from the share extension in Flutter Next, we want to take the text the user shared and display it in our . First, we need to read the text in our Swift class. ShareWidget Reading shared text inside the share extension view controller if let item: NSExtensionItem = self.extensionContext?.inputItems[0] as? NSExtensionItem, let itemProvider: NSItemProvider = item.attachments?[0] {
     if itemProvider.hasItemConformingToTypeIdentifier(UTType.text.identifier) {
         itemProvider.loadItem(forTypeIdentifier: UTType.text.identifier) {result,error in
             if error == nil {
                // TODO: Send data to Flutter
             }
         }
     }
 } This code gets the text data from the and, for now, does nothing. Eventually, we will add logic here to send it to the Flutter side of things. extensionContext Note: This piece of code works for this example, but it is not the safest way of writing this. Ideally, you want to iterate all items in instead of assuming it’s always just one item. self.extensionContext?.inputItems Sending data from share extension view controller to Flutter If you have worked with passing data between Flutter and Native you know that one of the go-to methods is to use a . Let’s start by setting it up on the Swift side: MethodChannel func showFlutter() {
     let flutterViewController = FlutterViewController(project: nil, initialRoute: "/share", nibName: nil, bundle: nil)
     
     let methodChannel = FlutterMethodChannel(name: "examples.share", binaryMessenger: flutterViewController.binaryMessenger)
     
     if let item: NSExtensionItem = self.extensionContext?.inputItems[0] as? NSExtensionItem, let itemProvider: NSItemProvider = item.attachments?[0] {
         if itemProvider.hasItemConformingToTypeIdentifier(UTType.text.identifier) {
             itemProvider.loadItem(forTypeIdentifier: UTType.text.identifier) {result,error in
                 if error == nil {
                     methodChannel.invokeMethod("setData", arguments: result as! String)
                 }
             }
         }
     }
     
     addChild(flutterViewController)
     view.addSubview(flutterViewController.view)
     flutterViewController.view.frame = view.bounds
 } We create a with the name , this name is important because its value needs to match exactly with the name configured on the channel in Flutter. We then use to call a function and send the text to it as an argument. FlutterMethodChannel examples.share invokeMethod setData Next, lets modify our in Flutter: ShareWidget import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

class ShareWidget extends StatefulWidget {
  // ...
}

class _ShareWidgetState extends State<ShareWidget> {
  var methodChannel = const MethodChannel('examples.share');
  var text = "";

  @override
  void initState() {
    methodChannel.setMethodCallHandler((call) async {
      if (call.method == "setData") {
        setState(() {
          text = call.arguments as String;
        });
      }
    });
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Text(text),
      ),
    );
  }
} We introduced a variable in the state so we can render the text being sent from Swift. We create a method channel with the name and then we add a method call handler. This handler will get invoked every time native tries to call a method on the , but in this example, we only need to worry about the function. To keep this example simple, we just take the arguments (we know there is only one in this case) and set the value of to it. text examples.share MethodChannel setData text And that’s it!

99 Stories To Learn About Ui

is a crucial component in web development, and C# developers need to have a deep understanding of how it works. Simply put, middleware is software that sits between a web application and the server, helping to manage requests and control data flow. Not only is there built-in middleware for us to use, but we can leverage custom middleware in ASP.NET Core! ASP.NET Core middleware It’s essential to have a deep understanding of middleware in ASP.NET Core since it can determine the performance and stability of a web application. Additionally, it can help C# developers address specific challenges in web development and enhance the user experience. This article aims to teach you how to harness the power of custom middleware in ASP.NET Core through working code examples. By the end of this article, you will be able to create custom middleware in ASP.NET Core and troubleshoot common issues, enabling you to build seamless web applications! Let’s dive into it! Understanding ASP.NET Core Middleware ASP.NET Core middleware is software that sits between a web server and application code. Its primary purpose is to process requests and responses as they pass in and out of the application. Middleware can add, modify, or remove data from the request and response pipeline, allowing developers to customize how their application interacts with the web server. There are various middleware types in ASP.NET Core, each serving a unique purpose in web development. Authentication middleware authenticates users, while routing middleware directs incoming requests to the appropriate endpoint. Static file middleware serves static files like images, JavaScript, and CSS files, while session middleware enables server-side data storage for user sessions. Types of Middleware in ASP.NET Core Here’s a more detailed overview of some of the different middleware types available in ASP.NET Core: : Provides mechanisms for authenticating user requests and asserting user identity to application components. Security is vital for modern applications, and authentication middleware lets developers implement secure authentication for their applications. Authentication Middleware : Directs incoming HTTP requests to the appropriate endpoint based on the request’s URL and HTTP method. Routing middleware ensures that the application only responds to requests that match the expected structure and format. Routing Middleware : Serves static files, like images, JavaScript, and CSS files, to the client. This prevents the server from handling requests for static files, freeing up resources to handle dynamic requests. Static Files Middleware : Enables server-side data storage for user sessions. Session middleware lets developers store and retrieve session data that can be accessed across multiple requests. Session Middleware Middleware can be used to address specific challenges in web development. For example, if there is a need to log incoming requests, middleware can be used to intercept incoming requests and log them to a file. If an application requires authentication, it can implement a custom authentication middleware that meets its specific requirements. There are numerous middleware in ASP.NET Core, each built for a specific requirement, and developers can use them to customize their applications. How to Use Middleware in ASP.NET Core Middleware is a powerful feature in ASP.NET Core that allows developers to customize the . request and response pipeline Here is a step-by-step guide on how to create middleware in ASP.NET Core: Create a new ASP.NET Core project in Visual Studio (or open your own existing project). Open the Startup.cs file in the project and locate the Configure method, which has an IApplicationBuilder parameter. If you’re working with an existing project, or minimal API project, this may have moved around. Register middleware by calling the Use method on the IApplicationBuilder parameter and passing in a delegate that represents your middleware logic. Use the Run method to configure the last middleware in the pipeline. public void Configure(IApplicationBuilder app)
{
    app.Use(async (context, next) =>
    {
        // Your middleware code logic goes here
        await next.Invoke();
    });

    app.Run(async (context) =>
    {
        await context.Response.WriteAsync("Hello, world!");
    });
} This example creates two middleware components, with the first acting on every request and the second handling only the final step in the pipeline. Note that the Use method adds the middleware into the pipeline, while the Run method is used to operate on the response. Implementing Custom Middleware in ASP.NET Core Creating custom middleware in ASP.NET Core is a straightforward process that involves implementing the IMiddleware interface. Here’s a step-by-step guide on how to create custom middleware in ASP.NET Core: Create a new class that defines the middleware. In this class, implement the IMiddleware interface, which requires you to implement an InvokeAsync method. Write the logic of the middleware by adding your code logic into the InvokeAsync method. Here is an example code for the custom middleware implementation: public class CustomMiddleware : IMiddleware
{
    public async Task InvokeAsync(HttpContext context, RequestDelegate next)
    {
        // Your middleware code logic goes here
        await next(context);
    }
} You can now add your new custom middleware into the pipeline. To do this, update the Configure method in the Startup.cs file, adding your custom middleware: public void Configure(IApplicationBuilder app)
{
    app.UseMiddleware<CustomMiddleware>();

    app.Run(async (context) =>
    {
        await context.Response.WriteAsync("Hello, world!");
    });
} By following these steps, you can add your custom middleware into the request and response pipeline, which allows you to control how requests are processed based on your application’s specific requirements. When implementing custom middleware, be sure to follow best practices for implementing and testing middleware to ensure your middleware is efficient and error-free. for building up confidence! Test coverage is important Common Challenges Faced with Middleware in ASP.NET Core As with any technology, C# developers may face some common challenges when working with middleware in ASP.NET Core. Here are some of the issues you might encounter: : Some middleware components may not be compatible with other middleware components or third-party libraries used in your application. This may result in runtime errors or unexpected behavior. Compatibility issues : Poorly designed middleware may cause performance issues that degrade an application’s responsiveness and speed. Performance issues : Misconfiguring or poorly designed middleware can introduce security risks, making an application vulnerable to attacks like XSS or CSRF. Security risks Have you tried implementing middleware before? What other issues did you run into? Troubleshooting Middleware Issues in ASP.NET Core When faced with middleware challenges, developers can and adopt best practices for identifying and addressing middleware issues. Here are some tips on how to troubleshoot middleware issues in ASP.NET Core: implement various troubleshooting strategies : Review your application’s log messages to gain more insight into issues. The logs can help identify where an issue is happening, what caused it, and what needs to be fixed. Check Log Messages : Debugging tools, such as breakpoints and stepping through code, are useful for tracing execution paths and understanding where an issue occurs in your application. This doesn’t work as well if you’re already running in prod! Use Debugging Tools : Consider testing middleware in isolation to identify its role in an issue. This can help identify whether a middleware component is the source of an issue or whether it’s being affected by other components. This is another reason why different testing approaches are critical. Test In Isolation : Adhere to established best practices for implementing and testing middleware. Ensure that your middleware code is clean and efficient and handles errors correctly. Testing is crucial to ensure that the middleware code is efficient and free of bugs. Follow Best Practices By following these troubleshooting techniques and best practices, developers can solve middleware challenges in ASP.NET Core efficiently. This ensures their applications perform optimally, are secure, and are free from unexpected errors. Wrapping Up Custom Middleware in ASP.NET Core This article has provided a detailed overview of middleware in ASP.NET Core and its significance in web development. We covered the different types of middleware in ASP.NET Core and how to use middleware in web development. Additionally, we discussed common challenges faced when working with middleware and their solutions. Some simple code examples can hopefully get you set in the right direction! Middleware is incredibly valuable in web development because it allows C# developers to add functionalities, modify requests, and perform other operations that cannot be accomplished with built-in features. Furthermore, middleware can help simplify the development process and enhance the overall user experience — If it’s done properly! I strongly encourage you to explore custom middleware in ASP.NET Core in your own projects!
