How to consume the JSON POST data in an Express application?
To consume the JSON POST data in an Express application, we call app.post.
For instance, we write
const express = require('express');
const app = express();
app.use(express.json());
app.post('/', (request, response) => {
console.log(request.body);
response.send(request.body);
});
app.listen(3000);
to call app.post with the route URL and the route handler callback.
In the callback, we get the request body from request.body.
request.body is available since we use the middleware returned by express.json with
app.use(express.json());
Conclusion
