Astro JS - Use Bun Environment
What is Bun?
Bun is a modern JavaScript runtime that comes as an alternative to Node.js and Deno. The Bun runtime is written in Zig which is a low-level programming language that is designed for performance and safety. Bun is designed to be fast, efficient, and easy to use. The key features of Bun include:
- Fast Startup Time − Bun has a very fast startup time compared to Node.js and Deno. This is because Bun uses a single binary that includes everything you need to run JavaScript applications.
- Built-in Package Manager − Bun comes with a built-in package manager, which is faster than npm and yarn.
- Built-in Bundler − Bun has a built-in bundler that can bundle JavaScript and TypeScript files into a single file.
Install and Setup Bun
To use Bun environment with Astro, you must install Bun locally on your machine. You can install Bun using the following command −
>> npm install -g bun
After installing Bun, you can verify the installation by running the following command:
>> bun run index.js
The above command will run the index.js file using Bun. If you see the output of the file, it means Bun is installed correctly.
Using Bun with Astro
To use Bun with Astro, you need to create a new Astro project using the following command:
>> bunx create-astro@latest my-astro-project-using-bun
This will create a new Astro project in the my-astro-project-using-bun directory. You can then navigate to the project directory and start the development server.
Install Dependencies
Dependencies are used to build and run the Astro project. If youâre starting a new project using bunx create-astro, the CLI will automatically use Bun to install dependencies and you can skip this step. Otherwise, youâll need to install your dependencies with Bun. You can install the bun dependencies using the following command:
>> bun install
Run Development Server
Development server is used to run the project in development mode. You can run the development server using the following command −
>> bun run dev
This will start the development server and you can view your Astro project in the browser at http://localhost:3000.
Create Production Build
The production build is used to create a production-ready version of the Astro project. You can create a production build using the following command:
>> bun run build
This will create a production build of the Astro project in the dist directory.
Add React Integration
In previous chapters, we have seen how to add React integration to the Node environment of Astro js. The same process is used to add React integration to the Bun environment of Astro js. You can add React integration using the following command:
>> bunx astro add react
This will add React integration to the Astro project. You can then use React components in your Astro project.
