Adding Middleware

Add middleware to authenticate requests or perform additional tasks

let myMiddleware = (req, res, next) => {
    //authentication code goes here
    next();
}

app.use(myMiddleware);

Building multiple CRUD interfaces:

GET /

app.get('/', (req, res) => {
    let response = Endpoints.list();
    res.send(response);
});

GET /:id

app.get('/:id', (req, res) => {
    let id = req.params.id;
    let response = Endpoints.getById(id);
    res.send(response);
});

POST /

app.post('/', (req, res) => {
    let response = Endpoints.create();
    res.send(response);
});

PUT /:id

app.put('/:id', (req, res) => {
    let id = req.params.id;
    let body = req.body;
    let response = Endpoints.update(id, body);
    res.send(response);
});

DELETE /:id

app.delete('/:id', (req, res) => {
    let id = req.params.id;
    let response = Endpoints.delete(id);
    res.send(response);
});
