sampleNodeProject is a basic CRUD app built with node, mongodb, and express.

Summary of day 1

Today we wrote the server, created a mongo database on mlab.com, wrote two REST Apis, and began working on the front-end javascript and css.

The server

We wrote a basic node server that listens on port 8081. We used express to set up the root route. When a GET request is sent to the root route, our server responds with hello world.

const express = require('express');
const app = express();
const port = process.env.PORT || 8081;

app.get('/', function (req, res) {
  res.send('hello world');
});

app.listen(port);

console.log('Listening on localhost:', port);

Then we set up a mongo database (see the database section of this wiki).

REST API Endpoints

We wrote an /add endpoint that will call our addPerson function it receives a POST request with an object in the body.

function addPerson(person) {
  MongoClient.connect(url, function(err, db) {
    assert.equal(null, err);
    console.log("Connected correctly to server");

     db.collection('demo').insertOne(person);

    db.close();
  });
}

app.post('/add', function(req, res) {
  let person = req.body;
  addPerson(person);
  res.send('Added!');
});
