In this exercise, you are going to extend the REST APIs you have been building to handle DELETE and PUT requests. You will also learn how to make your route handling more modular in express using express.Router.
- Use Express.Router to encapsulate routing behavior for different resources
- Explain and build a CRUD RESTful JSON API including PUT and DELETE
- Fork this repository
- Clone the forked repository onto your local machines
- In the root directory, type
npm install
, which installs dependencies for the project - Finally, type
npm start
, which starts a development server that will reload whenever you make any changes to source files
Your instructor will demonstrate how to encapsulate route parameters for the /users
endpoints using express.Router and also implement the PUT
and DELETE
endpoints for user.
- Implement the
films
andbooks
endpoints for this API according to the API spec
- Implement a
PATCH
method onbooks
andfilms
so that the client can update a subset of fields, rather than all of them. - Implement the following validation rules:
- The client should not be able to get, delete, or update a film that doesn't exist
- The client should not be able to add a film or book if one with the same title already exists
- When making a POST request, the client must specify a value for all required fields
- When any of these checks fail, have your API return an appropriate HTTP response code and error message.
- Use the express documentation to find out how to return different HTTP response codes.
