@j-o-r/apiserver

Fast http api server An easy way to expose a class/object as an API for micro http services

npm install --save @j-o-r/apiserver

Project Overview: This project is an HTTP API server designed to expose classes or objects as APIs.

Simple Usage Example:

import {server} from '@j-o-r/apiserver';
// This also could be an object
class TestController {
  static async index(client) {
    // Local endpoint: http://127.0.0.1:9022/testcontroller/index
    await client.serve(200, { 'joe': ['bar'] });
  }

  static async visitme(client) {
    // Local endpoint: http://127.0.0.1:9022/testcontroller/visitme?q=yes
    // @example:
    const params = client.parameters();
    const query = client.query();
    const method = client.method();
    await client.serve(200, { params, query, method});
  }

  /**
  * Stream/Chunk javascript content
  * @param {ClientWrapper} client
  */
  static async stream(client) {
    // Local endpoint: http://127.0.0.1:9022/testcontroller/stream
    // Create a stream
    client.writeHeaders(200);
    // Open object with an array
    await client.write('{"test":[');
    let i = 0;
    let len = 10;
    for (; i < len; i++) {
      // The last object should not have a ','
      const SEP = (i + 1 === len) ? '' : ','; 
      await client.write(JSON.stringify({
        id: i,
        date: new Date(),
        collection: ['one', 'two'],
        escape: ' escape " me'
      }) + SEP);
    }
    await client.write(']}');
    await client.end();
  }
  static error(client) {
    // Local endpoint: http://127.0.0.1:9022/testcontroller/error
    await client.serve(500, 'Error: an error');
  }
}
await server.create('testcontroller', { port: 9022, host: '127.0.0.1' }, TestController);

@see scenarios/apiObject.js for a more complete example.

Use case

A typical use case would be to launch this service on a high port (> 1024) as a regular 'linux' user. And create a VHOST in 'apache' or 'nginx' and re-route requests to the internal port.

NGINX example:

server {
    # --------------- customer conf ------------------
    server_name my.test.com;
    set $proxy_port 9022; # local port
    # ------------------------------------------------
    client_max_body_size 50M;
    client_body_timeout 60s;
    keepalive_timeout     70;
    add_header X-Robots-Tag "none" always;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto https;
    location / {
      # no se encuentra para todas las solicitudes
      return 404;
    }
    # This should reflects the namespace used on `server.create`
    location /testcontroller {
      # pasar solicitudes a punto final
      proxy_pass http://127.0.0.1:$proxy_port$request_uri;
    }
    # listen to IPV6 and http2
    listen [::]:443 ssl http2;
    # listen to IPV4 and http2
    listen 443 ssl http2;

    ssl_certificate /etc/cert//my.test.com/fullchain.pem;
    ssl_certificate_key /etc/cert/my.test.com/privkey.pem;
}

The url now would be:

https://my.test.com/testcontroller/index
