Node App

In this article, I’ll show you how to deploy a app and associate it with a domain. Node.js Let’s get right to it! 1. Buying everything we need: Server (VPS): I bought it on Digital Ocean because I have 200$ free on this service, and I can also , but you can also buy a VPS on sites such as: give you 200$ hostinger.com contabo.com Domain: I got a free one on namecheap.com, but you can also buy a domain on sites such as: hostinger.com godaddy.com domain.com 2. Setting up a VPS: Server settings: The server settings depend on the load your site will be under and the complexity of the project. Since I will be deploying a simple site, I chose the most minimal settings. For the authentication method, I chose a password. Once our server is up and running, we can start connecting to it. Copy the IPv4 or IPv6 address, then open a terminal and enter the following command: Ssh root@164.90.218.8(instead of 164.90.218.8 put your IPv4) After this, it will ask you to enter the password that you set when creating the VPS: When you successfully log in, you will see something similar to this: From there, we have two ways to transfer our project folder. If you have it in a zip file on your local computer, you can use these commands to transfer the zip file with your project to the server. #if you have authentication method thought password
scp your-archive.zip root@164.90.218.8:~/
#if you have authentication method thought ssh key
scp -i ~/.ssh your-archive.zip root@164.90.218.8:~/ However, I suggest that you use GitHub. Log in to and use “git clone” to put your project in the global directory. For example, I will use my Node.js project called “ ”. GitHub qr_code_hunt_challenge Then, we need to install packages. Use the following commands on our VPS: #to update everything
sudo apt update
#after it shows us that we have packages that we can upgrade
sudo apt upgrade
#when you get Do you want to continue? [Y/n], you just write Y After this, go to the git repository using this link and choose the version of Node.js you need. In my case, I will use the latest LTS version. Press the copy button next to the commands and insert them in our VPS: If you encounter any errors: sudo apt-get update
sudo apt-get install -f
sudo apt-get clean
sudo apt-get install -y nodejs
sudo apt Then: #to install vim, zip, nginx
sudo apt install vim zip nginx Now, we need to make some changes in the firewall settings: sudo ufw allow 'OpenSSH'
sudo ufw allow 'Nginx HTTP'
sudo ufw enable 
#after all this commands you need to write
sudo ufw status
#and you will get something like this
Status: active

To                         Action      From
--                         ------      ----
OpenSSH                    ALLOW       Anywhere                  
Nginx HTTP                 ALLOW       Anywhere                  
OpenSSH (v6)               ALLOW       Anywhere (v6)             
Nginx HTTP (v6)            ALLOW       Anywhere (v6) 3. Setting up a domain: First, we need to input our domain on the VPS hosting service. In my case, it is DigitalOcean. Go to the dashboard where you can check your VPS and start: When you insert the domain name and click “Add Domain,” you need to point to DigitalOcean in your nameservers. You can follow the guide from DigitalOcean using this . link In my case, I go to my dashboard in Namecheap and add everything as instructed in the guide: Second, we need to create a directory: sudo mkdir /var/www/your_domain.com
sudo chown -R $USER:$USER /var/www/your_domain.com/
sudo vim /etc/nginx/sites-available/your_domain.com The last command will open Vim, and here we need to insert this Nginx configuration: server {
    server_name your_domain.com www.your_domain.com;

    location / {
        proxy_pass http://localhost:3000;#here you need to change to your port
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
} Then, use these commands: rm -rf /etc/nginx/sites-available/default
rm -rf /etc/nginx/sites-enabled/default
sudo ln -s /etc/nginx/sites-available/your_domain.com /etc/nginx/sites-enabled/your_domain.com
#by next command you can check if everything okay
nginx -t
#now we need to reload our nginx
nginx -s reload Now, we need to move our Node.js project to another directory: cd /var/www/your_domain.com
mv ~/name_of_your_project_folder After using “ls,” you will see the folder or “.zip” file in your directory. If you just moved the “.zip” file, you need to unzip it using the command “unzip your_file.zip.” Now, we need to move all files from this directory: mv name_of_your_project_folder/* .
#and now we can delete this directory
rm -rf name_of_your_project_folder After that, use these commands: npm install
#and if you need some packages you can install now, in my case i will use:
npm init
npm install express
npm install ejs
npm install path
#and when you installed everything that you need, you can start your node.js
node server.js To make this site work without stopping: sudo npm install pm2@latest -g

pm2 startup systemd

pm2 start /var/www/your_domain.com/server.js

pm2 save

pm2 status
#after last command you should see If everything is okay, start using these commands: sudo systemctl start pm2-root

sudo systemctl reboot 4. Setting up HTTPS: To use HTTPS on our app, use these commands: sudo ufw allow 'Nginx Full'

sudo apt install certbot python3-certbot-nginx

sudo certbot --nginx -d your_domain.com -d www.your_domain.com

sudo systemctl status certbot.timer

sudo certbot renew --dry-run

sudo ufw delete allow 'Nginx HTTP'

#and if you upload some file on your app
sudo vim /etc/nginx/nginx.conf
#and here you need to insert in http {}
client_max_body_size 1000M; #here you can input any amout of megabytes

#and after all this
 nginx -t && nginx -s reload Now, our Node.js app is deployed and reachable through our domain, and everything is working. Finishing Up I hope you understood the instructions correctly.

Network applications are evolving and are now an inseparable part of our lives in this age of smart devices. Not only are the devices connected across the network, but they are also a part of one large, unified ecosystem known as the Internet. The internet today is a global community of users across the globe connected to each other at the tip of their fingers. And with the evolution of tech in the last decade it would be safe to say that the user experience now is the key factor to ensure the user makes a successful purchase decision. The speed, accessibility, and reliability of your network applications make sure the user’s journey from entering your application to completing target goals is seamless and your network applications help you achieve your target goals. To do so developers have opted for the framework on the server side to make network applications. Node.JS But, Node.JS must be paired with the right front-end framework to make sure the overall experience is not only seamless but also creative. This helps to grab the user’s attention and makes sure they engage long enough to make a purchase decision. Although there are choices available when it comes to front-end frameworks, the top choices have always been and . Angular React Which leads us to the biggest question in the Web industry, React vs Angular, which is the best choice for your node network application? Let’s demystify the mystery and try to answer the most asked question on the internet starting by understanding the Angular and React Front-end frameworks React React is a JavaScript library for building user interfaces. It has emerged as one of the most important front-end JavaScript libraries as it follows an element-based architecture, which breaks down the user interface into small, reusable elements. Choosing React has its own advantages for front-end development : React components can be easily reused throughout the entire application, promoting code consistency, saving costs, skipping code bloating, and reducing overall development time. Reusability : React utilizes a virtual Document Object Model to optimize rendering performance, updating only the components that need changes, resulting in a faster and smoother web surfing experience for end users. Virtual DOM : React's popularity has led to the creation of a massive user community and a huge ecosystem of libraries and tools, providing developers with seamless support and comprehensive resources. Large Community and Ecosystem : With React Native, developers can also build mobile applications for both Android and iOS platforms using the same React components, leading to better development efficiency. React Native React is undoubtedly the best choice for all developers looking for quicker development options with fast rendering and seamless user support that can help you create the best user experience, not only on the web but also for your Native Android or iOS Applications. Angular Angular is developed by It is a full-fledged front-end framework that has been through significant transformations, updating through the years. It embraces a declarative approach, depending on HTML templates and extending HTML with directives to bind data and manage component behavior. Google. The resulting development environment with Angular’s extensive library is expressive, and quick to create. Not just that, here’re the top reasons why Angular JS can be your front-end architecture : Angular offers two-way data binding, automatically synchronizing data between the model and the view, reducing the need for manual manipulation of the DOM. Two-way Data Binding : As Angular has a built-in dependency injection system, unit testing is simpler and more efficient, while promoting modularity, meaning that applications can be scaled and maintained more easily. Dependency Injection : Angular fully supports TypeScript i.e., it adds static typing to the language, enabling better code maintenance, and enhancing code readability. TypeScript Integration : Angular provides a powerful Command Line Interface (CLI) that automates many common tasks, making things easier for developers by avoiding redundant efforts. Powerful Command Line Interface With Typescript support and an auto-optimized DOM, Angular JS is the best choice for your next network application, Angular’s easy-to-develop environment makes it one of the best choices amongst developers. React VS Angular Although the choice of the right development framework depends a lot on the size of the project, the developer’s preference and expertise, and the complexity of the project you’re developing also come into play. Here’s a quick comparison to help you choose: Angular React Type A complete structural framework JavaScript-based library Purpose To build dynamic web apps To create interactive UI components Language TypeScript JavaScript (JSX script) Developed and maintained by Google Meta and Community Front-end development approach 1. Extends the functionality of HTML  2. Prefers client-side rendering 1. Preference for server-side rendering 2. Uses XML-like syntax called JSX DOM Real Virtual Performance High Relatively high (since virtual DOM renders updates much faster & ensures fast runtime performance) App structure Fixed and complex platform Flexible Data binding Two-way One-way Ideal use cases 1 Develop complex enterprise apps 2 Progressive and single-page web apps and websites 1 Modern and large web apps with continuously varying data 2 Natively rendered hybrid apps for Android and iOS devices Conclusion At , we understand your application preferences, and our expert MEAN and MERN stack developers can help you create enterprise applications, PWAs, Hybrid Applications, and responsive websites. With the right understanding of project requirements or consultants, choosing the best front-end framework is easy.

Hello, everyone! Today, we'll be diving into the fascinating world of software development, specifically dealing with a serverless Node.js application, Microsoft Azure, and . These tools may sound intimidating, especially if you're new to software development, but I assure you, with some guidance, they are quite manageable. So, let's buckle up and get ready to learn. Redis Content Overview Introduction to Redis, Node.js, and Azure Setting up Node.js with Azure Installing Redis Connecting Node.js with Redis Testing the setup Introduction to Redis, Node.js, and Azure is an open-source, in-memory data structure store used as a database, cache, and message broker. It's a NoSQL key-value store that's excellent for handling data with high velocity or volume. Redis is a runtime environment for executing JavaScript code server-side. It's used for building scalable and efficient network applications. Node.js is Microsoft's cloud computing platform and service, where we'll be deploying our Node.js application. Specifically, we'll use , a serverless computing service that allows you to run your code without provisioning or managing servers. Azure Azure Web App Setting up Node.js with Azure For setting up all the required resources, I briefly explained in my previous article . How to Deploy a Serverless Node.js Application on Azure Installing Redis We need to install the Redis package on the Node.js project: npm install redis Then, we need to add some code to file: app.js import redis from 'redis';
import { createServer } from 'http';


// Create an redis conn.
const client = redis.createClient();
client.on('error', err => console.log('Redis Client Error', err));
await client.connect();

// For test.
await client.set('testKey', 'Hackernoon!');
const value = await client.get('testKey');

const server = createServer((req, res) => {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    res.end(`Hello, ${value}\n`);
});

server.listen(8080, '0.0.0.0', () => {
    console.log('Server running at http://0.0.0.0:8080/');
}); In package.json we need to add type: module: {
  "name": "hackernoon",
  "version": "1.0.0",
  "type": "module",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "redis": "^4.6.7"
  }
} Deploy it to the cloud and click “Start streaming logs“ (Img 1). Don’t forget to open the URL in the browser, it will turn on our web app after deployment. On the logs stream you will see: Redis Client Error Error: connect ECONNREFUSED ::1:6379 Now, we are ready to create a Redis app inside Azure and connect it. Connecting Node.js with Redis Search for Redis. On the Services, you will see “Azure Cache for Redis“ (Img 2). Click on “Create Redis cache“. You should choose the resource group that is using your Web App (Img 4). Create a resource and wait some time. Usually, it takes several minutes to complete. Then go to the resource “Overview” page and copy and paste it to the code": “Hostname” import redis from "redis";
import { createServer } from "http";

// Create an redis conn.
const client = redis.createClient({
  url: "redis://hackernoon.redis.cache.windows.net",
  password: "<Your PRIMARY password from Azure Redis Resource>",
});
client.on("error", (err) => console.log("Redis Client Error", err));
await client.connect();

// For test.
await client.set("testKey", "Hackernoon!");
const value = await client.get("testKey");

const server = createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader("Content-Type", "text/plain");
  res.end(`Hello, ${value}\n`);
});

server.listen(8080, "0.0.0.0", () => {
  console.log("Server running at http://0.0.0.0:8080/");
}); Password value you can find in “Access keys“ (Img 5). Also, go to Advanced settings, which is below “Access keys“ and put “No“ to Allow access only via SSL“. It will enable the Redis cache to work via the 6379 port. Testing the setup Finally, test your setup locally by running your Nodejs with the command. Your function should be able to access your Azure Redis instance. For deployment, push your project to Azure, and it should connect to the Azure Redis Cache. yarn start That's it! You've successfully created a Redis instance and connected it to a serverless Node.js application on Azure. Remember, Don’t make db, redis, and other resources to be public, and remember to use SSL. Try to create a closed virtual network and use it. Close everything if possible inside your private network. This guide is only for testing and learning. Practice is key when it comes to software development. Don't hesitate to tinker around with different settings and functionalities of Redis, Node.js, and Azure. The more you experiment, the better you understand. Happy coding!

How to Create and Connecting Redis to a Serverless Node.js App on Azure

Welcome to this comprehensive guide, where we will cover deploying a Serverless Node.js application on , one of the most popular cloud service providers globally. This tutorial is designed for beginners in software development, so we will take things slow and explain concepts in detail. Amazon Web Services (AWS) Before we dive in, it's important to understand what we're working with. Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine, which lets developers create scalable network applications. AWS, on the other hand, offers a suite of cloud services that allow you to host and scale your applications. One of these services is AWS Lambda, a serverless computing service that runs your code in response to events. In this article, we will discuss: Prerequisites Setting up your AWS account Creating a simple Node.js application Installing and configuring the Serverless Framework Deploying your application on AWS using the Serverless Framework Prerequisites A basic understanding of JavaScript and Node.js. Node.js and (Node Package Manager) are installed on your local machine. You can download them from . npm here An AWS account. If you don't have one, you can create it from . here Setting up your AWS account After setting up your AWS account, you need to create a new user in AWS Identity and Access Management (IAM): Login to your AWS Management Console. Navigate to IAM, and then click on (Image 1) "Users." Click on (Image 2). "Add users" Enter a and press the button. username next Set permissions by attaching existing policies directly. For simplicity, use In a production environment, it's advised to limit the permissions, but for this guide, we will give admin access to our account (Image 3). Click "AdministratorAccess" Next. Review the details and click on After the user is created, you should click on the name of our account and go to and click on (Image 4). "Create user." “Security credentials“ “Create access key“ Select and accept options. Setup description and press . You'll be shown an access key ID and a secret access key. Make sure to store them safely, as you won't be able to view the secret access key again. “Third-party-service“ Alternative recommended “Create access key“ Creating a Simple Node.js Application How to create a simple app, I have described in my previous articles and . How to Deploy a Serverless Node.js Application on Azure Deploying a Serverless Node.js Application on Google Cloud Firstly, it's important to note that AWS Lambda functions do not support listening on HTTP ports like a regular Node.js application might. Instead, AWS Lambda functions are event-driven, meaning they respond to events like HTTP requests through the API Gateway. Secondly, AWS Lambda functions should export a handler function that takes an event object, context object, and a callback as parameters. This function is what AWS Lambda will call when your function is invoked. Therefore, your original code should be modified to fit this model. Here's the modified code: app.js exports.handler = async (event, context) => {
    const response = {
        statusCode: 200,
        headers: {
            'Content-Type': 'text/plain',
        },
        body: 'Hello World\n',
    };
    return response;
}; A package.js will be: {
  "name": "hackernoon",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
} Save all these files to your project folder and you are ready to go. Installing and Configuring the Serverless Framework The Serverless Framework helps you develop and deploy AWS Lambda functions. It's a CLI tool that needs to be installed globally. Install the Serverless Framework: npm install -g serverless Setup your AWS credentials with the Serverless Framework: serverless config credentials --provider aws --key <your_key> --secret <your_secret> Replace and with the access key ID and secret access key you got when creating the IAM user. <your_key> <your_secret> In your project directory, create a new file named . serverless.yml Open and add the following configuration: serverless.yml service: hackernoon-test

provider:
  name: aws
  runtime: nodejs18.x

functions:
  hello:
    handler: app.handler
    events:
      - http:
          path: hello
          method: get This configuration defines a new service named . It specifies that we're using AWS as our provider and Node.js 18.x as our runtime. It also defines a function named that will execute our function in . hackernoon-test hello handler app.js Deploying your Application on AWS Now that we've set up our application and the Serverless Framework, we can deploy our application: Deploy the service: serverless deploy Open your browser and navigate to your fresh link: Deploying hackernoon-test to stage dev (us-east-1)

✔ Service deployed to stack hackernoon-test-dev (58s)

endpoint: GET - https://37c01fcgfj.execute-api.us-east-1.amazonaws.com/dev/hello                     
functions:
  hello: hackernoon-test-dev-hello (531 B) And there you have it! You've just deployed your first Serverless Node.js application on AWS. As you can see, the Serverless Framework simplifies the process, letting you focus on writing your application. Conclusion In this guide, we've covered the basics of deploying a Serverless Node.js application on AWS. We've only scratched the surface of what's possible with AWS and the Serverless Framework, and there's much more to explore. Remember, the best way to learn is by doing, so don't be afraid to experiment and build your own applications. Happy coding!

Create Hello World Nodejs app Creating a "Hello World" Node.js application in Visual Studio Code (VS Code) is straightforward. Here's a step-by-step guide on how to do that: : If you haven't already, you'll need to install Node.js and npm (which comes with Node.js) on your machine. You can download Node.js and npm from the official Node.js website: Install Node.js and npm https://nodejs.org/ : Open VS Code, and create a new folder for your project. You can do this by clicking on and then create a new folder. Create a new folder for your project File > Open Folder... : You can do this by clicking on . This will open a new terminal at the bottom of your VS Code window. Open a new terminal in VS Code Terminal > New Terminal : In the terminal, type . This will create a new file in your folder with default values. Initialize a new Node.js application npm init -y package.json : Click on to create a new file, and save it as in your project folder. Create a new file for your application File > New File app.js : In the file, type the following code: Write your "Hello World" program app.js const http = require('http');

const server = http.createServer((req, res) => {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    res.end('Hello World\n');
});

server.listen(3000, '127.0.0.1', () => {
    console.log('Server running at http://127.0.0.1:3000/');
}); This code creates a simple HTTP server that responds with "Hello World" for every request. : In the terminal, type to start your application. You should see the message "Server running at ". Run your application node app.js http://127.0.0.1:3000/ : Open a web browser, and go to . You should see "Hello World". Check your application http://127.0.0.1:3000 Upload local project to Azure cloud You should open extension in your VS Code app. Then you will see, Azure App Service Right-click on the resource and click on Deploy to Web App. hackernooontestapp Then you need to choose the project folder. 5:32:36 PM: Deployment to "hackernoontestapp" completed. After deploying the app, you will cause some Azure errors. 5:33:59 PM: "hackernoontestapp" reported a critical error: Cannot find module '/home/site/wwwroot/index.js' This error means that we need to open file and make some changes to it. package.json {
  "name": "hackernoon",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
} It should look like this. We have replaced with and added a start script to it. By default, when you select based on Linux, it will open an 8080 port in a docker container, that’s why we need to change our app.js code. “main“: “index.js“ “main“: “app.js“ Azure Web App const http = require('http');

const server = http.createServer((req, res) => {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    res.end('Hello World\n');
});

server.listen(8080, '0.0.0.0', () => {
    console.log('Server running at http://0.0.0.0:8080/');
}); Deploy the app again, and finally, you will see on your browser!  Don’t forget to reboot your cloud app on the Azure website. In case of some problems, you can right-click on your web app and click on your VS Code extension. You will see error messages and can deal with them.

Remember, practice makes perfect. So, continue exploring, and before you know it, you'll be an expert in deploying serverless applications.

How to Deploy a Serverless Node.js Application on Azure

Pheww!! You have worked hard and put all the effort into creating a dream Node.Js app for your project. After numerous hours of coding and debugging, you have finally come up with an end-product. Now the time has to launch your product in the market where anyone can see and use it. Yuppie!! Excited, Aint’ you? In this guide, I will explain the step-by-step process of deploying your first Node.Js application to the server using . web application development services So, let’s start now! Getting Started Well, using cloud-based technologies, you can deploy an app in different ways. If you , they may sure many services like Microsoft Azure, Google Cloud, or AWS to host your web app. Also, you and your team can use PaaS services like Heroku for quick and easy deployment. hire experienced NodeJs developers Moreover, deploying your Node.Js application to a bare Linux server on Cloud is difficult to find the right configuration and stack of technologies that stand up to your expectations. There are many Virtual Private Server – VPS you may come across from different reliable platforms. But, here, we are going to use Hostinger as it’s cost-effective and easy to configure with different add-ons. Here, I am using Ubuntu’s latest version – 20.04. So, follow the required steps to deploy your Node.Js app to a bare server. Here, we will use MySQL (As per your requirements of the app) DBMS Setup: For re-visiting HTTP Requests to our internal Node.Js Server, we’ll use . Setup a Reverse Proxy: Nginx Install Node & NPM. Install PM2 Node.Js Process Manager. From version control push/clone your code. Configure reverse proxy and run a local server. Follow the above steps to access your server’s IP or domain name on PORT 80 through your Node.Js app. Also, as a default port, 80 is considered for serving HTTP. Now, you are required to have an SSH to your server while using Hostinger. You will be able to see the server’s IP address on the right-hand side. You can keep SSH as root. ssh root@ 42.35 .40 .01 From Hostinger Cpanel, you can change the password of SSH. Install MySQL Database Its installation process is the same as other Debian (Ubuntu) packages throughout the apt. sudo apt install mysql-server sudo apt update When you run the configuration script, you have to make sure that you have accepted all the required permission from the server. Now configure the MySQL Deamon server. It will give tight security in a production-ready environment. sudo mysql_secure_installation After giving a command to the server, you can change some of the security options of MySQL. However, you have to configure the Validate Password Plugin in the first window. This way, you can check your MySQL password’s strength. For the second window, you have to set MySQL root user password. Once you are done with the window, you will have to press Y and Enter for accepting the defaults for all the subsequent questions. Now, no anonymous users can get through it. Moreover, it will also disallow remote root logins, erase the test database, and integrate these new rules. MySQL will adapt to the changes immediately. Don’t forget to check whether the MySQL server is running or not with the given command. systemctl status mysql If you see an Active or running status, this means your server has been successfully started without any issue. Now, connect the server with the MySQL client. mysql -u root Whoaa! Now, we have successfully configured the Database Server without any errors. mysql quit Nginx Reverse Proxy Here, we use Nginx reverse proxy to receive multiple requests from clients and serve it to different servers. We will use the Nodejs server here. As per my experience, Nginx is an amazing and reliable HTTP Server. It’s commonly used to serve static HTML Files and reverse proxy. It provides internal access to a server or those resources that are behind a firewall. Here, in our case, we will run the NodeJs app on port 3000 behind a firewall. Only through localhost, we can access it. Now, bind Nginx reverse proxy to port 80 – available for the public. Afterward, it can serve the localhost Nodejs server. Now is the time to install Nginx. sudo apt install nginx sudo apt update Now, apache2 is installed with Hostinger. It is fully configured to server HTTP on PORT 80. Hence, we have to disable apache2 from our server. sudo apt-get remove apache2* After using the command, all the apache2 packages and sub-packages will not be available. Now configure your Nginx server with a simple Test webpage. But before proceeding further, we have to install a firewall to secure our server. So, let’s install ufw (uncomplicated firewall). sudo apt install ufw To access your server in the future, you have to ensure that all the SSH connections pass through the firewall only. ufw allow ssh You have to write a given code to check which network application is available and has access through the firewall. >  Available applications:
   Nginx Full
   Nginx HTTP
   Nginx HTTPS
   OpenSSH ufw app list Opens both port 80 (normal, unencrypted web traffic) and port 443 (TLS/SSL encrypted traffic) Nginx Full: Opens only port 80 Nginx HTTP: Opens only port 443 Nginx HTTPS: Since we need HTTP through ufw, let’s allow Nginx. Allow the Nginx HTTPS or the Nginx Full. > Status: active
To                         Action      From
--                         ------      ----
OpenSSH                    ALLOW       Anywhere
Nginx HTTP                 ALLOW       Anywhere
OpenSSH (v6)               ALLOW       Anywhere (v6)
Nginx HTTP (v6)            ALLOW       Anywhere (v6) sudo ufw allow 'Nginx HTTP' If you can see allow in the action box of OpenSSH and Nginx HTTP, you are on the right path. As we can assume that, it also supports IPV6 Protocol. With a bellow written code, check the Nginx status. sudo systemctl status nginx Keep the Nginx status active. If it has not started automatically, then do it manually. sudo systemctl start nginx After completing this, we have to set up Nginx Server Block. From our given servers or multiple independent domains, you can serve subdomains. /etc/nginx/ Nginx Configuration address: : /var/www/ Nginx Main Server Root address Now, let’s create the main IP address or domain serving page root. sudo mkdir -p / var /www/servername.com/html Make sure the permission of web root should be correct with the given code. sudo chmod -R 755 / var /www/servername.com Here, -R (recursive) will define all servername.com sub-directories having the same permission as the parent directory. Then, write a given code. This code will assign the ownership of the directory having the existing user named $USER environment variable: sudo chown -R $USER:$USER / var /www/example.com/html Now, let’s make a simple index.html webpage for testing purposes. Then integrate the proxy of the Nginx server to our localhost running the NodeJs app. nano / var /www/servername.com/html/index.html Write the below-given HTML code inside. </html> <html> < head > < title > Welcome to servername.com! </ title > </ head > < body > < h1 > Success! The servername.com server block is working successfully! </ h1 > < b > Meow Meow! </ b > </ body > Now close the Nano text editor after saving. Moreover, we should add configuration at /etc/nginx/sites-available for Nginx to serve this content. sudo nano /etc/nginx/sites-available/servername.com You should keep the config file the same as your domain name to be easy for you to maintain. For a simple Nginx configuration, here is the code. index index.html index.htm index.nginx-debian.html; location / { } 
} server { listen 80 ; listen [::]: 80 ; root / var /www/servername.com/html; #Here, you can put your domain name for ex: www.servername.com server_name 42.35 .40 .01 ; try_files $uri $uri/ = 404 ; is only available for storing your configuration. If you have to make it active, create a link to the config to the sites-enabled directory to see the effect on the server. /etc/nginx/sites-available sudo ln -s /etc/nginx/sites-available/servername.com /etc/nginx/sites-enabled/ If you want to check errors in the new add config, run the below code. nginx -t Now, restart the Nginx for the new config for the modification. sudo systemctl restart nginx Now, try to browse the address of the server’s IP or domain name. You will be able to view the test page of the sample webpage served back to you. So, the Nginx server is running successfully behind the ufw firewall. Install Node Here, we will use , which you can download from . Generally, you can install Node from the apt package manager, but it will not let you install the latest version. NVM GitHub sudo apt install wget wget -qO-https: //raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash It will consider the script and execute it with bash to install NVM. install.sh To apply environment changes, you need to run the .profile or .bashrc from your home folder. And this completely depends upon your requirements and configuration. source ~/.profile source ~/.bashrc Now run command. It will run like a charm. nvm nvm -v 0.34 Now install Node and using NVM with the following code. NPM nvm install 11.0 Then Node and NPM commands will be available across the command line. node -v 11.0 Install PM2 and Cloning Repo is a NodeJs process manager. It tracks your running Node process to make a debug easier. Also, it shows the log files of running apps. PM2 Let’s install it. npm install pm2 -g It’s very easy to install, like the PM2 process. Now, there is a requirement of the Node.Js app’s code on the server. So, we will use Git Version Control to push and then clone the repository. git push origin master git add . git commit -m "Initial Commit" git remote add origin "https://github.com/username/your_repo" Now clone the repository with the given code. cd repos mkdir repos git clone https: //github.com/username/your_repo Suppose the framework is based on a simple Node.Js or Express server with app.js, then you need to use PM2 to start the process. cd /repos/your_repo Use PM2 now. pm2 start server app.js Here, we will use the app.js instance with PM2. We named it “server” so that we can easily identify our application. Once you are done with this process, you will get a table showing the running/stopped apps and CPU usage. Configure Reverse Proxy The Nginx configuration is already added with a simple index.html page. Now bind it to a localhost address, representing the address of the existing running NodeJs app. This is where an Nginx takes its place for a reverse proxy. Now open the config and do essential changes to work as a reverse proxy. servername.com { location /  

{ 
                proxy_set_header X-Real-IP $remote_addr; 
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
                proxy_set_header Host $host; } 
} server listen 80 ; server_name 42.35 .40 .01 ; proxy_set_header X-NginX- Proxy true ; proxy_pass http: //localhost:3000/; proxy_redirect http: //localhost:3000/ https://$server_name/; Once you implement the above code, all your questions from Nginx will be redirected to . And that’s the place where you will find the NodeJs server running. http://localhost:3000 Now change the host and port of your existing NodeJs app. The provided custom headers will be sent with the proxied request to our NodeJs servers - $remote_addr and $host. These represent the real IP address of those users who raised the requests initially. Finally, everything is covered, and the setup is complete. You can access your server IP address or domain name on the browser where the NodeJs server handles the request. Isn’t that pretty cool? Haah!! Anyway, it’s a very cool thing to use a reverse proxy and port 3000 (NodeJs server port). However, this secures your web server or application. Bang on! You have deployed a NodeJs application on the server. Furthermore, if you are planning to develop a feature-rich NodeJs application, you can always have an by your side. That would help you lead the world with your ideas and their executions. experienced NodeJs development company
