@universal-adapter/server v0.8.0

@universal-adapter

Like adapters for power outlet, but for JavaScript.

For now, there are only adapters for server frameworks (Express, Hapi, Koa).

Server adapters

The server adapters allow you to write server code that can work with several server frameworks.

• Express adapter: @universal-adapter/express
• Hapi adapter: @universal-adapter/hapi
• Koa adapter: @universal-adapter/koa

Example

We define routes / and /hello/{name} that will work with Express, Hapi, and Koa:

// /example/helloPlug.js

module.exports = helloPlug;

async function helloPlug({pathname, method}) {
  if( method!=='GET' || !pathname.startsWith('/hello/') ) {
    return null;
  }
  return {
    body: 'hello '+pathname.slice('/hello/'.length),
    headers: [
      {name: 'Cache-Control', value: 'public, max-age=31536000, immutable'}
    ]
  };
}

We can now use helloPlug with either Express, Hapi, or Koa:

// /example/express

const express = require('express');
const ExpressAdater = require('@universal-adapter/express');
const helloPlug = require('../helloPlug');

module.exports = start();

function start() {
  const app = express();

  app.use(
    new ExpressAdater([
      helloPlug,
    ])
  );

  app.listen(3000, () => console.log('Express server running at http://localhost:3000'));
}

// /example/hapi

const Hapi = require('hapi');
const HapiAdapter = require('@universal-adapter/hapi');
const helloPlug = require('../helloPlug');

module.exports = start();

async function start() {
  const server = Hapi.Server({
    port: 3000,
    debug: {request: ['internal']},
  });

  await server.register(
    new HapiAdapter([
      helloPlug,
    ])
  );

  await server.start();
  console.log('Hapi server running at http://localhost:3000');
}

// /example/koa

const Koa = require('koa');
const KoaAdapter = require('@universal-adapter/koa');
const helloPlug = require('../helloPlug');

module.exports = start();

function start() {
  const server = new Koa();

  server.use(
    new KoaAdapter([
      helloPlug,
    ])
  );

  server.listen(3000);

  console.log('Koa server running at http://localhost:3000');
}
