Here we create a basic hello world server using Express. Routes:
- '/'
- '/wiki'
- for rest will give "404" , i.e. page not found.
let port = process.env.PORT || 3000;
let app = require('express')();
app.listen(port);
app.get('/',
(req, res) =>
res.send('Hello Morol!')
);
app.get('/wiki',
(req, res) =>
res.send('This is wiki page.')
);
app.use((req, res) =>
res.send('404-Page Not Found')
);Note: We have put 404 route as the last route as Express stacks routes in order and processes them for each request sequentially.
