Coding Extensions – Step by Step Guide

When coding chrome extensions for developers, first of all you need to create a folder and add the following files.

Step 1 – manifest.json

This is the file that will provide Chrome with basic information related to your extension such as required permission and its name. The majority of the variables in the manifest file are quite self-explanatory and you can change any of them. The matches variable is responsible for running the select content.js when the extension helps a particular webpage is launched.

  • “<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.
  • “*://*/*”: will match any URL that uses the https: or http: scheme.

Step 2 – content.js

This is a JavaScript file that’s executed in the context of web pages. It means that this file enables content script to interact with websites and web pages that the user opens in their Chrome browser.

Step 3 – Image Icon

Add your icon file in png format to the folder. You can either download or create an icon for your extension.

Step 4 – background.js

While you have installed the extension, there are no instructions present. Create a file named background.js and add a background script. Place this file in the extension folder. Ensure that you’ve registered your background script in the manifest which tells your extension what files to reference and how certain files will act.

Step 5 – Creating and Naming Extension

Once you are done, add all the files to a folder and name it after your extension.

Intuitive design is how we give the user new superpowers.
