How To Use

First setup mongo database

* for hosting mongodb server locally see setup-mongodb.md for how to

* Run the create-dotenv-file.sh script to create the .env file

code npm i to install the NPM packages

code npm run startServer to start the server

app folder is parent folder

• /models/ folder
  • the models folder contains the object definitions for saving to the mongo database.

  const mongoose = require('mongoose');
  const DataSchema = new mongoose.Schema({
      name: {
      type: String,
      required: true,
      minlength: 1,
      trim: true,
      }
  })
  module.exports = mongoose.model('Data', DataSchema);

  • to create a new entry in the database, call the .save() method on the object. This usually goes in a route for the POST method

  const Data = require('../models/data');
  const data = await new Data({
    name
  }).save()

• /routes/ folder
  • this will store the routes for the REST api. create a route for each type of data stored in the database.

  const express = require('express');
  const bodyParser = require('body-parser');
  const mongoose = require('mongoose');
  const dataRoute = require('./routes/data');
  const router = require('express').express.Router();
  const Data = require('../models/data');
  
  //mongoDB
  mongoose.Promise = global.Promise;
  mongoose.connect(getSecret(secretNames.dbUri)).then(
    () => {
      console.log('Connected to mongoDB');
    },
    (err) => console.log('Error connect ing to mongoDB', err)
  );
  
  router.post('/', async (req, res) => {
      try {
          const {name} = req.body;
          const data = await new Data({name}).save()
          res
          .status(201)
          .json({
              title: 'Created New Data',
              detail: 'Successfully create new dataentry',
              json: { name,}
              });
      }catch (err) {
              res.status(400).json({
                  errors: [
                          {
                          title: 'RegistrationError',
                          detail: 'Something wentwrong',
                          errorMessage: err.message,
                          },
                  ],
              });
      }
  });

• server.js file
  • this is where the server goes and singleton objects. include each route and

//express 
const app = express();
const port = getSecret(secretNames.port);
//middleware
app.use(bodyParser.json());
app.use(cors())
//routes
app.use('/api/data', dataRoute);

app.listen(port, () => {
  console.log(`Server running on port ${port}`);
});

module.exports = { app };

• secrets.js file
  • use this as a layer for the .env variables

require('dotenv-expand').expand(require('dotenv').config({path:'../.env'}))

const secrets = {
  dbUri: process.env.DB_URI || '',
  port: process.env.PORT || 3000
};
const secretNames = {
  dbUri:'dbUri',
  port:'port',
}

const getSecret = (key) => secrets[key];

module.exports = { getSecret, secretNames };
