HyperBun is meant for Bun runtimes, it will not work in Node / Deno.

A simple HTTP routing library built on top of Bun's built in HTTP solution.

Getting started

bun add hyperbun

Example

import {createServer} from 'hyperbun';

const server = createServer();

server.middleware((request, context) => {
  console.log('Just a simple middleware...');
});

server.middleware((request, context) => {
  return Error('Oops, I returned a 500.');
});

server.get('/json', (request, context) => {
  return {
    hello: 'I will automatically become a JSON response...'
  }
});

server.get('/text', (request, context) => {
  return "Hello, I will be a text/html response...";
});

server.listen({
  port: 3000,
  hostname: '0.0.0.0'
});

Request Context

Includes {params: {}, query: {}} by default. More to come.

import {createServer} from 'hyperbun'

const server = createServer();

server.middleware((request, context) => {
  context.auth = {user: '1234'};
});

// /home?search=movies
server.get('/home', (_, context) => {
  console.log(context.query) // { search: "movies" }
  return 'OK';
})

server.get('/private', (_, context) => {
  if (context.auth?.user !== '1234') {
    // Return your own custom responses too.
    return new Response('unauthorized', {
      status: 401,
    })
  }

  return {
    private: 'data',
  }
})

server.listen({port: 3000});

Dynamic routes with params

import {createServer} from 'hyperbun';
const server = createServer();

server.post('/users/:userId', async (request, context) => {
  const {userId} = context.params;
  const updatePayload = await request.json();

  await UserModel.updateById(userId, updatePayload);
  return { success: "true" };
});

server.listen({
  port: 3000,
  hostname: "0.0.0.0",
});

Send a file response

import {createServer, asAttachment} from 'hyperbun';

const server = createServer();

server.get('/file', () => {
  return Bun.file('./test-file.txt'); // Inline
})

server.get('/file', () => {
  return asAttachment('./test-file.txt', { // Attachment (download)
    name: 'helloworld.txt'
  });
})

server.listen({
  port: 3000,
  hostname: '0.0.0.0',
});

Consuming a request body

import {createServer} from 'hyperbun'

const server = createServer();

server.post('/users/add', async (request, context) => {
  const user = await request.json();
  const result = await database.create(user);
  return result;
});

Create multiple Routers and use on base path

import {createServer, createRouter} from 'hyperbun';

const server = createServer();
const router1 = createRouter();
const router2 = createRouter();

server.get('/', () => new Response('/ server main router'));

router1.get('/', () => new Response('/users router'));
router2.get('/', () => new Response('/posts router'));

server.use('/users', router1);
server.use('/posts', router2);

server.listen({
  port: 3000,
})

Available methods

These listeners will automatically match the route and method that you setup and respond with a 404 for ones you don't have.

server.get server.post server.put server.delete server.patch
