Week 7 API Design

HTTP Method Mayhem

100

This HTTP method reads all tasks from /api/tasks.

What is GET?

200

This HTTP method creates a new task.

What is POST?

300

This HTTP method updates one task at /api/tasks/:id.

What is PUT?

400

This HTTP method removes one task at /api/tasks/:id.

What is DELETE?

500

In “the URL is the address; the method is the verb,” this part tells the server what job to do.

What is the HTTP method?

Express Route Room

100

Add this middleware line so Express can read JSON request bodies.

What is app.use(express.json());?

200

In a POST route, the submitted JSON body appears on this Express object.

What is req.body?

300

In /api/tasks/:id, this part of the route is a placeholder.

What is :id?

400

Express stores the URL value from /api/tasks/:id here.

What is req.params.id?

500

This code turns the route id from a string into a number.

What is Number(req.params.id)?

Status Code Street

100

A successful POST that creates a new task should return this status code.

 What is 201?

200

Empty POST bodies should return this status code because the client sent bad data.

What is 400?

300

If the route exists but the requested task id does not, return this status code.

 What is 404?

400

This Express chain sends both a 400 status and a JSON error body.

What is res.status(400).json(...)?

500

The path exists, but no task matches the id. This kind of 404 comes from this source.

What is our route handler, or our code?
