How to access POST form fields with Node.js and Express?
To access POST form fields with Node.js and Express, we can use the body-parser package.
To install it, we run
npm install --save body-parser
Then we write
const bodyParser = require('body-parser')
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true
}));
to require the body-parser package.
And then we call app.use with bodyParser.json() to let us parse JSON payload from POST requests in our routes.
And we call bodyParser.urlencoded to let us parse URL encoded POST request payloads in our routes.
