Building 'The Builder' - The Road from Commit to Production in 13s

The motivation for writing this article is to provide clear instructions on how to create a file upload that looks attractive. The native button looks very minimalistic, but it can be improved. Unfortunately, there is no browser API that allows you to open the upload dialog without the input tag, so let's clarify how to do this. Pure JS - so it can be adapted to any framework;
No native upload button - we want custom button instead
Accessibility - strong trend of last several years Let’s Make a Pretty Button As I mentioned earlier, we still need to render an input with type="file" to support the browser API. Since we don’t want it to be visible, let’s hide it. Here’s a code example in pure HTML/CSS/JS: <body>
    <style>
        main {

</body> Important Details Use semantic HTML tags. This will help readers understand the job better;
For uploaded files, use role="status" and aria-live="polite". This way, the file upload message is accessible to users;
Adding a trash icon with an aria-label helps screen readers identify its purpose, making the button more accessible;
Using aria-describedby lets screen readers read content from another element, providing extra details about the component.

Accessible Custom File Upload

About me As a software engineer, I love building products that solve problems which people around me have. I think there's too many tech companies out there doing things that are abstract or just to make a quick buck. Whilst it's important to feed your family, I think it's more important to build things that matter. The problem I noticed The inspiration for Product Upload came from watching my Mum working on her online store. Every fortnight she spends hours copying products from her suppliers' websites into her Wix store. Manually finding them, screenshotting the images, copying the descriptions, prices, names, and important info and then pasting them into Wix. This sparked an idea, but I didn't do anything about it for a few months. Then my wife started her own online store and I saw her doing the same thing. She was more high tech and used a spreadsheet in the process too but the process was still tedious and time-consuming. After seeing 2 of 2 people I know running online stores doing the same thing I realised surely this is a problem that everyone working with suppliers in their online store face. So then I started coding… I started by building a basic website, which used some pretty rudimentary scraping techniques to copy products from a few websites. I showed it to my Mum and she loved it. She was able to copy products in seconds instead of hours. I then started building a more robust version of the tool, which could copy products from any website. I added a bunch of features like image selection, automatic SEO optimisation, and a bunch of more advanced features. Now, 6 weeks since launch I have over 20 paying subscribers, official apps on both the Wix and Shopify app stores and I’m growing by about 10 users a week. Product Upload is one of those products that people genuinely seem to love and I’m stoked! The future shape of Product Upload I feel like I've only scratched the surface of what Product Upload is capable of. There's a real disconnect between stores and their suppliers which leads to a lot of manual work which distracts from the core business of running a store. Not only do I see Product Upload becoming better and better at copying products, but I also hope to be able to more deeply integrate with suppliers and stores to make the whole process much more enjoyable for both parties. Follow the Product Upload journey by visiting my website Visit Product Upload About me As a software engineer, I love building products that solve problems which people around me have. I think there's too many tech companies out there doing things that are abstract or just to make a quick buck. Whilst it's important to feed your family, I think it's more important to build things that matter. The problem I noticed The inspiration for Product Upload came from watching my Mum working on her online store. Every fortnight she spends hours copying products from her suppliers' websites into her Wix store. Manually finding them, screenshotting the images, copying the descriptions, prices, names, and important info and then pasting them into Wix. Product Upload This sparked an idea, but I didn't do anything about it for a few months. Then my wife started her own online store and I saw her doing the same thing. She was more high tech and used a spreadsheet in the process too but the process was still tedious and time-consuming. After seeing 2 of 2 people I know running online stores doing the same thing I realised surely this is a problem that everyone working with suppliers in their online store face. So then I started coding… I started by building a basic website, which used some pretty rudimentary scraping techniques to copy products from a few websites. I showed it to my Mum and she loved it. She was able to copy products in seconds instead of hours. I then started building a more robust version of the tool, which could copy products from any website. I added a bunch of features like image selection, automatic SEO optimisation, and a bunch of more advanced features. Now, 6 weeks since launch I have over 20 paying subscribers, official apps on both the Wix and Shopify app stores and I’m growing by about 10 users a week. Product Upload is one of those products that people genuinely seem to love and I’m stoked! Wix Shopify The future shape of Product Upload I feel like I've only scratched the surface of what Product Upload is capable of. There's a real disconnect between stores and their suppliers which leads to a lot of manual work which distracts from the core business of running a store. Not only do I see Product Upload becoming better and better at copying products, but I also hope to be able to more deeply integrate with suppliers and stores to make the whole process much more enjoyable for both parties.

File uploads are a common feature in many web applications, but handling them efficiently and securely can be challenging. In this article, we will explore how to implement efficient file uploads using Node.js, Express.js, and MongoDB. We will cover the entire process, from setting up the server to storing files in MongoDB GridFS, ensuring that your application can handle large files without sacrificing performance. Problem Statement Handling file uploads efficiently involves several challenges: Scalability: Managing large files without overwhelming server memory.
Security: Preventing unauthorized access and ensuring data integrity.
Performance: Uploading and retrieving files quickly.
Storage Management: Efficiently storing and retrieving files from the database. Solution We will use the following stack to address these challenges: Node.js: For the server-side environment.
Express.js: As the web framework.
Multer: Middleware for handling multipart/form-data, which is used for uploading files.
MongoDB: For storing metadata and files.
GridFS: A specification for storing and retrieving large files in MongoDB. Step-by-Step Implementation 1. Setting Up the Project First, let’s create a new Node.js project and install the necessary dependencies. mkdir file-upload-app
cd file-upload-app
npm init -y
npm install express multer mongoose gridfs-stream 2. Creating the Server Next, we will set up a basic Express server. // server.js
const express = require('express');
const mongoose = require('mongoose');
const multer = require('multer');
const { GridFsStorage } = require('multer-gridfs-storage');
const Grid = require('gridfs-stream');

  gfs = Grid(conn.db, mongoose.mongo);
  gfs.collection('uploads');
});

// Create storage engine
const storage = new GridFsStorage({

  file: (req, file) => {
    return new Promise((resolve, reject) => {
      crypto.randomBytes(16, (err, buf) => {
        if (err) {
          return reject(err);
        }

const port = 5000;

app.listen(port, () => console.log(`Server started on port ${port}`)); 3. Testing the Upload Feature We can test our implementation using tools like Postman. Upload a File: Use a POST request to http://localhost:5000/upload with form data containing the file.
Retrieve Files: Use a GET request to http://localhost:5000/files to get the list of all files.
Retrieve a Single File: Use a GET request to http://localhost:5000/files/:filename to get a specific file’s details.
Display Image: Use a GET request to http://localhost:5000/image/:filename to view the image in the browser.
Delete a File: Use a DELETE request to http://localhost:5000/files/:id to delete a file.

The Noonification: HTML Image Uploader: A Useful Guide (8/29/2024)

In today’s digital landscape, images and file uploads are integral to both websites and mobile apps, whether for user-generated content or internal use. Online tools, social media platforms, and internal systems all require efficient file upload capabilities to function smoothly. For instance, image editing tools and social media sites rely on effective file uploader services to handle image files. Moreover, internal teams often need to upload various types of files, such as product images, logos, and videos. To accommodate these needs, developers must implement a reliable file uploader. Fortunately, HTML makes it straightforward to create a fast and functional image uploader. In this article, we’ll explore how to set up a basic HTML image uploader with ease. Key Takeaways HTML Basics: HTML (Hypertext Markup Language) is a standard markup language that forms the building blocks of web pages. HTML, along with CSS and JavaScript, forms the basis of modern websites. HTML defines the page structure and content, but JavaScript is used for dynamic functions and CSS for styling.


A Close Look at HTML Image Uploader: An HTML image uploader is a tool that allows users to upload images to a web page. This is usually done through a simple form and is part of the interactive features of web applications.


How to Create an HTML Image Uploader: Creating a simple image uploader with HTML is quite easy using basic HTML tags. This process involves configuring the image upload form and the necessary tags.


Adding an Image to a Button with JavaScript: Using JavaScript, it is possible to dynamically add an image to the image uploader button. This provides visual effects that increase the user interaction. Discovering Filestack and How It Helps in File Uploads: Filestack is a platform that simplifies file uploading processes. It simplifies and optimizes developers’ file management by providing high-capacity uploading, conversion, and storage features. Understanding HTML: The Building Blocks of Web Pages HTML is the acronym for Hypertext Markup Language. It is the standard markup language used to create web pages. HTML, along with CSS (Cascading Style Sheets ) and JavaScript, form the basis of almost every modern website. With HTML, we essentially create the structure of the page, such as sections, paragraphs, and links, by using HTML elements like tags and attributes. In other words, it tells the web browser the content of a web page should be displayed. However, HTML isn’t a programming language because it doesn’t allow us to create dynamic functionality. As a result, we use JavaScript to add dynamic elements to our web page and CSS for styling. There are several HTML tags available that we can use to create different elements. Here are some of the most used HTML tags: <html> – This tag basically defines the entire HTML page or document.
<head> – It consists of meta information, such as the title of the page.
<body> – This is basically the document’s body, and it consists of all the content that is visible on the web page, such as paragraphs, headings, images, lists, tables, hyperlinks, and more. What Is An HTML Image Uploader? An image uploader, as the name suggests, is a feature on a website or web app that allows users to upload image files. These include a JPEG image, PNG, GIF, etc. An image uploader also transfers the uploaded images to the server. It is provided as a built-in feature of the website by embedding it into the HTML code. As a result, users don’t need to download and install an image uploader separately. While creating an image uploader, developers must ensure that it is fast, secure, and efficient. Thankfully, with HTML, we can implement the image upload feature pretty easily using the <input> (file input element) How to Create An HTML Image Uploader? Here are the simple steps for inserting and customizing an image uploader with HTML: Using <input type=”file”> To Create The File Upload Button Below is an example code for creating an upload file button in HTML: You can also find the code here. That’s it. We’ve inserted the file upload button. Now, we can customize the image uploader as needed. If you want to learn how to resize images in HTML, check out this article. Customizing The Text Within The Button If you want to display some other text instead of ‘choose file,’ you can use the code below to change the text within the file upload button: You can also find the code here. Hiding The Button In some cases, you may wish to hide the button. We can achieve this using CSS: You can also find the code here. Here we’ve set the opacity to 0, which will make the input transparent. The z-index value ensures that the element remains underneath everything else on the page. Customizing The Design Of The HTML Image Uploader We can also customize the button further to make it look attractive. For example, we can change the default grey buttons: You can also find the code here. However, we now have two file upload buttons – the default grey one and the customized button we created using the above code. To hide the default grey button, you can use the code provided in the above step. Limiting Image File Types Sometimes, we want to limit the types of files the users can upload to the server, especially for security purposes. We can specify the allowed file extension or extensions: You can also find the code here. Adding An Image To The Button Using JavaScript Now, let’s write the JavaScript code to show the image in <img id=”output”> element. You can also find the code here.

Discovering Filestack and How It Helps in File Uploads: Understanding HTML: The Building Blocks of Web Pages Understanding HTML: The Building Blocks of Web Pages HTML is the acronym for Hypertext Markup Language. It is the standard markup language used to create web pages. HTML, along with CSS (Cascading Style Sheets ) and JavaScript, form the basis of almost every modern website. With HTML, we essentially create the structure of the page, such as sections, paragraphs, and links, by using HTML elements like tags and attributes. In other words, it tells the web browser the content of a web page should be displayed. However, HTML isn’t a programming language because it doesn’t allow us to create dynamic functionality. As a result, we use JavaScript to add dynamic elements to our web page and CSS for styling. There are several HTML tags available that we can use to create different elements. Here are some of the most used HTML tags: <html> – This tag basically defines the entire HTML page or document. <head> – It consists of meta information, such as the title of the page. <body> – This is basically the document’s body, and it consists of all the content that is visible on the web page, such as paragraphs, headings, images, lists, tables, hyperlinks, and more. <html> – This tag basically defines the entire HTML page or document. <head> – It consists of meta information, such as the title of the page. <body> – This is basically the document’s body, and it consists of all the content that is visible on the web page, such as paragraphs, headings, images, lists, tables, hyperlinks, and more.
