Created a Node module using Express router to support the routes for the dishes REST API.
Index.js file:
const express = require('express');
const http = require('http');
const morgan = require('morgan');
const bodyParser = require('body-parser');
const app = express(); // here we are saying that our application are going to use express node module
const dishRouter = require('./route/dishRouter');
app.use('/dishes/:dishId', dishRouter);
const hostname = 'localhost';
const port = 3000;
app.use(bodyParser.json()); // This allows us to parse the body of the request message
app.use(morgan('dev')); //it will print out additional information to the screen as required
app.use(express.static(__dirname + '/public')); // This will serve the static files
app.use((req, res, next) => {
console.log(req.headers);
res.statusCode = 200;
res.setHeader('Content-Type', 'text/html');
res.end('<html><body><h1>This is an express server </h1></body></html>');
});
const server = http.createServer(app); // here we set up the server using express App
server.listen(port,hostname,() => {
console.log(`Server runnig at http://${hostname}:${port}`);
})
DishRouter.js file:
const express = require('express');
const bodyparser = require('body-parser');
const dishRouter = express.Router({mergeParams:true});
dishRouter.use(bodyparser.json());
dishRouter.route('/') //mount this express router at the /dishes endpoint.chain all GET PUT POST DELET method already do this router
.all((req,res,next) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
next();
})
.get((req,res,next) => {
res.end('Will send all the dishes to you!');
})
.post((req,res,next) => {
res.end("Will add the dish : " + req.body.name + " with details: " + req.body.description);
})
.put((req,res,next) => {
res.statusCode = 403;
res.end('PUT is not supported by /dishes');
})
.delete((req,res,next) => {
res.end('Deleting all the dishes');
});
// Routes for specific dish
dishRouter.route('/:dishId')
.all((req,res,next) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
next();
})
.get((req,res,next) => {
res.end('Will send the dish ' +req.params.id +' to you!');
})
.post((req,res,next) => {
res.statusCode = 403;
res.end('POST operation not supported on /dishes/'+req.params.id);
})
.put((req,res,next) => {
res.write('Updating the dish: ' + req.params.id + '\n');
res.end("Will add the dish : " + req.body.name + " with details: " + req.body.description);
})
.delete((req,res,next) => {
res.end('Deleting the dish '+req.params.id);
});
module.exports = dishRouter ;
This need to support GET, PUT, POST and DELETE operations on each of the endpoints. The code is properly working for dishes but For dishId it is showing same results as dishes.
When sending a GET request to localhost:3000/dishes/28, the following response is sent:
Will send all the dishes to you!
