Coding Extensions – Step by Step Guide

When writing code for Chrome extensions intended for developers, the first thing you need to do is create a folder and then add the following files to it.

Step 1 – manifest.json

This is the file that will supply Chrome with fundamental details regarding your extension, such as the permissions it requires and its name. You don’t need an explanation for most of the variables in the manifest file; in fact, you can edit any of them to suit your needs. The execution of the choose content is the responsibility of the matches variable. JavaScript at the time that a specific web page is loaded.

  • “<all_urls>”: will match any URL that begins with an approved scheme such as http:, https:, file:, ftp:, or chrome-extension:.
  • “http://*/*”: will match any URL that uses the http: scheme.
  • “https://*/*”: will match any URL that uses the https: scheme.

Step 2 – content.js

Step 3 – Image Icon

Put your icon file in there, and make sure it’s in png format. You have the option of downloading an existing icon or creating one from scratch for your extension.

Step 4 – background.js

Despite the fact that the extension was successfully deployed, there are no instructions available. Make a new file with the name background.js, then add a background script to it. Put this file in the folder designated for extensions. Make sure that your background script has been registered in the manifest, which will tell your extension what files to reference and how particular files will behave.
