RESTful API With Node.js And Hapi with my favorite Netflix movies and tv shows
- NodeJS - NPM installed
- Postman
We are going to use MongoLab to host our database, so we don't need to have MongoDB installed on our machine.
- Open the terminal and create a new folder for the project
mkdir netflix_favs - Navigate to the root of the folder
cd netflix_favs - Create the package.json file
npm init - Create a file called server.js
touch server.js - Create a folder called api
mkdir api - Inside api folder, we are going to create folders for models, controllers and routes
mkdir api/controllers api/models api/routes - Create talksController.js and speakersController.js in the api/controller folder
touch api/controllers/talksController.js api/controllers/speakerController.js - Create routes.js in the routes folder
touch api/routes/routes.js - Create talkModel.js and speakerModel.js in the model folder
touch api/models/talkModel.js api/models/speakerModel.js
- Install express
npm install hapi --save - Install nodemon as dev dependency
npm install --save-dev nodemon - On the package.json we are going to add the following script
"start": "nodemon server.js" - This will be our initial server.js
'use strict';
const Hapi = require("hapi");
const port = process.env.PORT || 3000;
const server = new Hapi.Server({
host: "localhost",
port: port
});
server.route({
method: "GET",
path: "/",
handler: (request, response) => {
return "Hello World";
}
});
const start = async () => {
try {
await server.start();
}
catch (err) {
console.log(err);
process.exit(1);
}
console.log('Server running at:', server.info.uri);
};
start();- On ther terminal
npm run startso this will start the server
- Install mongoose
npm install mongoose --save - Our speaker model should look like this:
'use strict';
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const MovieSchema = new Schema({
name: {
type: String,
unique : true,
required: 'Please enter the name of the movie'
},
description: {
type: String,
required: 'Please enter the description of the movie'
},
coverUrl: {
type: String,
required: 'Please enter the cover url of the movie'
},
review: {
type: String,
required: 'Please enter the review of the movie'
}
});
module.exports = mongoose.model('Movie', MovieSchema);- Our routes file should look like this:
'use strict';
module.exports = function (server) {
const movies = require('../controllers/moviesController.js');
server.route({
method: 'GET',
path: '/movies',
handler: movies.list_all_movies
});
server.route({
method: 'POST',
path: '/movies',
handler: movies.create_a_movie
});
server.route({
method: 'GET',
path: '/movies/{id}',
handler: movies.get_a_movie
});
server.route({
method: 'PUT',
path: '/movies/{id}',
handler: movies.update_a_movie
});
server.route({
method: 'DELETE',
path: '/movies/{id}',
handler: movies.delete_a_movie
});
}- Require routes.js on server.js
const routes = require('./api/routes/routes.js');- Call the function on server.js
routes(server);- Our speakers controller should look like this:
'use strict';
const mongoose = require('mongoose');
const Movie = mongoose.model('Movie');
exports.list_all_movies = function (req, res) {
return Movie.find({}).exec().then((movie) => {
return { movies: movie };
}).catch((err) => {
return { err: err };
});
};
exports.create_a_movie = function (req, res) {
const movieData = {
name: req.payload.name,
description: req.payload.description,
coverUrl: req.payload.coverUrl,
review: req.payload.review
};
return Movie.create(movieData).then((movie) => {
return { message: "Movie added successfully", movie: movie };
}).catch((err) => {
return { err: err };
});
}
exports.get_a_movie = (req, h) => {
return Movie.findById(req.params.id).exec().then((movie) => {
if(!movie) return { message: 'Movie not Found' };
return { movie: movie };
}).catch((err) => {
return { err: err };
});
}
exports.update_a_movie = (req, h) => {
return Movie.findById(req.params.id).exec().then((movie) => {
if (!movie) return { err: 'movie not found' };
let movieData = movie;
movieData.name = !!req.payload.name ? req.payload.name : movie.name;
movieData.description = !!req.payload.description ? req.payload.description : movie.name;
movieData.coverUrl = !!req.payload.coverUrl ? req.payload.coverUrl : movie.coverUrl;
movieData.review = !!req.payload.review ? req.payload.review : movie.review;
movie.save(movieData);
}).then((data) => {
return { message: "Movie data updated successfully" };
}).catch((err) => {
return { err: err };
});
}
exports.delete_a_movie = (req, h) => {
return Movie.findById(req.params.id).exec().then((movie) => {
if (!movie) return { message: 'Movie not found' };
movie.remove(movie);
}).then((data) => {
return { success: true };
}).catch((err) => {
return { dberror: err };
});
}As mentioned before, we are going to use MongoLab to host our database, in fact it's already created, so let's connect :)
- Create a connection.js file
- Inside that file require mongoose, speaker and talk models
'use strict';
const mongoose = require('mongoose');
const Speaker = require('./api/models/speakerModel');
const Movie = require('./api/models/movieModel');- Connect to de database
Mongoose.connect('mongodb://medjs:medjs2017@ds121089.mlab.com:21089/netflix_movies');
let db = Mongoose.connection;
db.on('error', console.error.bind(console, 'connection error'));
db.once('open', function callback() {
console.log('Connection with database succeeded.');
});
exports.db = db;- Require connection.js on server.js
const connection = require('./connection.js');- Call the connection function on server.js
connection();Finally the server.js file should look like this:
'use strict';
const connection = require('./connection.js');
const Hapi = require("hapi");
const port = process.env.PORT || 3000;
const routes = require('./api/routes/routes.js');
const server = new Hapi.Server({
host: "localhost",
port: port
});
connection.db;
routes(server);
const start = async () => {
try {
await server.start();
}
catch (err) {
console.log(err);
process.exit(1);
}
console.log('Server running at:', server.info.uri);
};
start();
