Quick start

You can install Mapl from npm.

npm i @mapl/app

Create a new file and add the following code:

import { jitc, router } from '@mapl/app';

// Create a router
const app = router()
  // Add a route that matches GET requests to '/'
  .get('/', () => 'Hi');

// Build the app
const result = await jitc(app);

// Export the function to be executed
export default { fetch: result.fetch };

Then run the file with Bun or Deno.

# Bun
bun server.ts

# Deno
deno serve server.ts --port 3000

And done! We just build a simple web server running on 127.0.0.1:3000.

Explanation

First we create a router instance by calling router().
```
const app = router();
```
Then we add an endpoint that returns Hi as a response.
```
const app = router()
  .get('/', () => 'Hi');
```
You can return anything that is supported by the Response constructor, which includes string, ArrayBuffer, Blob, ReadableStream, …

Chaining is also possible since every method returns the current app instance.
```
const app = router()
  .get('/', () => 'Hi')
  .get('/hello', () => 'Hello');
```

Then we use the compiler to create an object that contains a request handler.

const result = await jitc(app);
result.fetch; // This is the request handler

Finally we export the function correctly for the runtime to execute.
