Exercise: Try it out module: express-bodyparser.js HIGHTLIGHT: using express and body-parser : app.use, app.post

Create a Node.js project and install the following dependencies: [email protected] [email protected] this project requires 'npm install express body-parser' in terminal

Copy the above example code into a new JavaScript file and run the program. Test the code with this command: http -v :4000 foo=bar. Thanks to the -v flag you should see both the HTTP request and response Confirm that the api logs the request body to the console Now make a similar request but using HTTPie's "form" mode: http -v --form :4000 foo=bar Confirm that the HTTP request is of the type application/x-www-form-urlencoded and that the express application logs the same information as before.

Exercise: adding ERROR HANDLER: module: express-errorhandler.js Reuse the Node.js project from the previous exercise. Create a new JavaScript file and include the following code: const express = require('express') const app = express() const port = 3000 app.get('/', (req, res, next) => { // Your code goes here }) app.listen(port, () => console.log(Example app listening on port ${port}!)) Implement the logic in the handler function so that 50% of the time (using Math.random()), we trigger the built-in error handler, and the other 50% of the time we respond with the text "Ok". Call your endpoint several times and confirm that 50% of the time you get an error page (HTML).
