Quick Tutorial: Creating Your First Bun Project with TypeScript Support

by

Are you ready to start your journey with Bun, the modern JavaScript runtime? This quick tutorial will guide you through creating your first Bun project with TypeScript support, making it easier to build robust and type-safe applications.

Prerequisites

  • Node.js installed on your machine (version 14 or higher)
  • Basic knowledge of JavaScript and TypeScript
  • Internet connection to download Bun

Installing Bun

To begin, install Bun by running the following command in your terminal:

curl -fsSL https://bun.sh/install | bash

Once installed, verify the installation with:

bun --version

Creating a New Bun Project with TypeScript

Navigate to the directory where you want your project and run:

bun init my-typescript-project --template typescript

This command creates a new project folder with TypeScript support already configured.

Understanding the Project Structure

Inside your project folder, you’ll find:

  • src/index.ts: The main TypeScript file where you’ll write your code.
  • package.json: Contains project dependencies and scripts.
  • tsconfig.json: TypeScript configuration file.

Writing Your First TypeScript Code

Open src/index.ts and add the following code:

console.log('Hello, Bun with TypeScript!');

Running Your Project

To run your project, use the command:

bun run

You should see Hello, Bun with TypeScript! printed in your terminal.

Next Steps

Now that your project is set up, you can start adding more TypeScript files, install dependencies, and build your application. Bun makes it easy to develop with modern JavaScript and TypeScript features.

Happy coding!
