About this course

For learners who finished the JavaScript and browser courses. In about 11 hours you will build a small HTTP API with Node's built-in modules, validate requests, return correct status codes, and test it with real requests 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.
