import { WebApp } from 'meteor/webapp';

// Basic
WebApp.connectHandlers.use('/hello', (req, res, next) => {
  res.writeHead(200);
  res.end(`Hello world from: ${Meteor.release}`);
});

// Getting Data From Post
WebApp.connectHandlers.use('/route-name', (req, res) => {
  let body = '';
  req.on('data', Meteor.bindEnvironment((data) => {
    body += data;
  }));

  req.on('end', Meteor.bindEnvironment(() => {
    const data = JSON.parse(body);
    
    // Here is where you can do stuff with the data.
    // I use this technique for writing webhook routes instead of adding
    // an additional package.
    
    res.writeHead(200);
    res.end('Success');
  }));
});
