How to Develop Microsoft Edge extensions

First, I decided to learn about the general development process for Microsoft Edge extensions, which is the type of app I want to develop.

General development process

The general process from development to publishing for Microsoft Edge extensions is as follows. I’ve learned that development involves using HTML, JavaScript, and CSS. However, I don’t have experience with any of these…

1. Creating a manifest file
   • JSON file
     • A file that contains the app’s information
2. Implementation
   • JavaScript file
     • A file defining the app’s features and functions
   • HTML and CSS files
     • A file defining the user interface
3. Test
   • It seems I can side-load the extension into my browser to test its functionality.
4. Publish my extension to browser stores
   • Register for a developer account
   • Submitting the complete set of the extension files for review and approval

  • It mentioned testing in various environments, but what specific environments or conditions should I consider for testing?
• Which web browsers should I target?
  • Which web browser is the most commonly used? (Microsoft Edge, Safari, Firefox, Chrome, Opera or Brave)
  • What is Chromium
• How to receive recommended badges
  • Is it checked during the application process?
  • If it’s not approved, can I reapply?
