Working on these challenges will involve you writing your code using one of the following methods:
During the development process, it is important to be able to check what’s going on in your code.
Node is just a JavaScript environment. Like client side JavaScript, you can use the console to display useful debug information. On your local machine, you would see console output in a terminal.
We recommend to keep the terminal open while working at these challenges. By reading the output in the terminal, you can see any errors that may occur.
The server must be restarted after making changes to its files.
You can stop the server from the terminal using Ctrl + C and start it using Node directly (node mainEntryFile.js) or using a run script in the package.json file with npm run.
For example, the "start": "node server.js" script would be run from the terminal using npm run start.
To implement server auto restarting on file save Node provides the --watch flag you can add to your start script "start": "node --watch server.js" or you can install an npm package like nodemon. We will leave this to you as an exercise.
Modify the myApp.js file to log "Hello World" to the console.
"Hello World" should be in the console
const response = await fetch(code + '/_api/hello-console');
if (!response.ok) {
throw new Error(await response.text());
}
const data = await response.json();
assert.isTrue(data.passed, '"Hello World" is not in the server console');
