Question
body-parser has already been installed and is in your project's package.json file. require it at the top of the myApp.js file and store it in a variable named bodyParser. The middleware to handle URL encoded data is returned by bodyParser.urlencoded({extended: false}). Pass the function returned by the previous method call to app.use(). As usual, the middleware must be mounted before all the routes that depend on it.
Solution
Here are the steps to require body-parser in your myApp.js file and use it:
-
Open your
myApp.jsfile in your text editor. -
At the top of the file, add the following line of code to require
body-parserand store it in a variable namedbodyParser:
var bodyParser = require('body-parser');
- Next, you need to use the
bodyParser.urlencoded({extended: false})method to handle URL encoded data. This method returns a middleware function that you need to pass toapp.use(). Add the following line of code:
app.use(bodyParser.urlencoded({extended: false}));
Remember, this middleware must be mounted before all the routes that depend on it. So, make sure you add this line before your routes in the myApp.js file.
That's it! You have now successfully required body-parser in your myApp.js file and used it to handle URL encoded data.
