About this course

After the JavaScript and browser courses, build a small service that other programs can ask for information. In about 11 hours, use Node.js to check requests, send clear replies and test the service on your own computer.

What you will be able to do

Build documented endpoints with appropriate HTTP methods and status codes.
Validate inputs and return useful, consistent errors.
Keep secrets on the server and test requests without a browser interface.
