Overview

The Chrome Extension TypeScript Starter is a template for building Chrome extensions using TypeScript and Visual Studio Code. It provides a project structure, set of tools, and example code to help developers quickly get started with building Chrome extensions.

  • TypeScript: The template uses TypeScript as the programming language for building the Chrome extension, which provides the benefits of static typing and improved code organization.
  • Webpack: Webpack is included in the template to bundle and optimize the JavaScript code for the Chrome extension, ensuring faster loading times and better performance.
  • React: The template includes support for React, a popular JavaScript library for building user interfaces, allowing developers to create rich and interactive extension UIs.
  • Jest: Jest is included as the testing framework in the template, enabling developers to write and run unit tests for their Chrome extension code.

Once you have Node.js and npm installed, follow the steps below to set up and build the Chrome extension:

  1. Import the project as a Visual Studio Code project by opening it in Visual Studio Code.
  2. Build the project in watch mode by executing the command Ctrl + Shift + B in the Visual Studio Code terminal.
  3. Load the extension to Chrome by navigating to the dist directory and selecting it as the extension directory in the Chrome Extensions page.
  4. Test the extension using Jest by running the command npx jest or npm run test in the Visual Studio Code terminal.
