next-bar: Better API Routes for Next.js

Higher order function for Next.js that makes it easier to orchestrate API route handlers based on the request's method.

What?

Instead of having to do this:

// pages/api/hello.ts
export default function(req, res) {
  if (req.method === 'GET') {
    return res.send('Hello from GET!');
  }

  if (req.method === 'POST') {
    return res.send('Hello from POST!');
  }

  // ...
}

you can now do this:

// pages/api/hello.ts
import bar from 'next-bar';

function get(req, res) {
  return res.send('Hello from GET!');
}

function post(req, res) {
  return res.send('Hello from POST!');
}

export default bar({ get, post });

Usage

1. Install the module:

Using npm:

npm install next-bar

Using yarn:

yarn add next-bar

2. Define per-method routes:

// Tip: You can export these functions in separate files and import them in your
// route to organize your source code better.

function getUser(req, res) {
  const user = User.findOne(/* ... */);
  return res.json({ ok: true, user });
}

function createUser(req, res) {
  const user = User.create(/* ... */);;
  return res.json({ ok: true, user });
}

// ...

3. Import the library and use it as your API route's default export:

import bar from 'next-bar';

// ...

export default bar({
  get: getUser,
  post: createUser
});

Tip: You can define a custom handler for unsupported requests by providing a fallback property when calling bar():

function fallback(req, res) {
  return res.status(405).json({
    ok: false,
    error: `Method ${req.method} is not allowed.`
  });
}

export default bar({
  // ...,
  fallback
});

Supported Methods

The library supports the following methods: GET, POST, PATCH, PUT, DELETE, OPTIONS.
