The first step of Bun

As you know, Bun is the fastest JavaScript runtime and the substitute for Node.js.

Today, I want to introduce the first step of Bun.

Install Bun globally 

# Open your terminal
$ curl -fsSL https://bun.sh/install | bash
Enter fullscreen mode Exit fullscreen mode

Create a TypeScript file 

# In your terminal
$ touch index.tsx
Enter fullscreen mode Exit fullscreen mode 
// index.tsx
const server = Bun.serve({
  port: 3000,
  fetch(request) {
    return new Response("Welcome to Bun!");
  },
});

console.log(`Listening on localhost:${server.port}`);
Enter fullscreen mode Exit fullscreen mode

Lounch a server with Bun 

# In your terminal
$ bun run index.tsx
Enter fullscreen mode Exit fullscreen mode

http://localhost:3000/

Welcome to Bun!!!
