nodeProvider provides a single node http server instance to every AbstractResource instance to allow each request to be handled by one resource subclass

abstract-resource.js

const { createClass, inject } = require("kaop");
const { nodeProvider } = require("./node-server");
const url = require("url");

module.exports = AbstractResource = createClass({
  constructor: [inject.args(nodeProvider), function(resourceIdentifier, node) {
    this.uri = resourceIdentifier;
    node.server.on("request", (req, res) =>
      req.url.includes(resourceIdentifier) && this.processRequest(req, res));
  }],
  processRequest(req, res) {
    const query = url.parse(req.url, true).query;
    let body = "";
    req.on("data", d => body += d);
    req.on("end", () => this.dispatch(req, res, query, body));
  },
  dispatch(req, res, query, body) {
    req.body = body ? JSON.parse(body): null;
    req.query = query;
    const methodName = req.method.toLowerCase();
    this[methodName](req, res);
  }
})
