Developed a Node module utilizing the Express router to facilitate 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(); // indicating the use of the express node module
const dishRouter = require('./route/dishRouter');
app.use('/dishes/:dishId', dishRouter);
const hostname = 'localhost';
const port = 3000;
app.use(bodyParser.json());
app.use(morgan('dev'));
app.use(express.static(__dirname + '/public'));
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);
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('/')
.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');
});
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 ;
The implementation required to support GET, PUT, POST, and DELETE operations on each endpoint. Although the code works correctly for dishes, it presents the same results for dishId as well.
Upon sending a GET request to localhost:3000/dishes/28, the following response is returned:
Will send all the dishes to you!
