Http example

Your assignment will be to create a key-value database service. It should follow these guidelines:

  • It should be an HTTP server, running on port 4000 on your computer. It just needs to run locally, and doesn't need to follow any production-ready requirements (ie, you can have debug/development mode turned on).

Project spec

We'd like you to implement the following basic features of a key-value database, running as an HTTP service.

  • For all endpoints:
    • Each endpoint should accept JSON and return JSON.
    • Each endpoint should respond with appropriate error codes: 200 for success, 4XX for user error, 5XX for server error.
  • For data storage:
    • You should store data in memory
    • Ideally using a well known data structure from your programming language's standard library.
  • A "Set" endpoint:
    • It should use the POST HTTP method
    • It should be available at the /set url path
    • The request should contain a JSON POST body consisting of a JSON entry of the following form: {"key": "", "value": "" }.
    • This endpoint should set the key value pair in memory.
    • The keys and values should be strings only
    • If successful, the response should be the JSON object that was just set.
  • A "Get" endpoint
    • It should use the GET HTTP method
    • It should be available at the /get url path
    • The request should be of the form: /get?key=someKey, which should return the value stored in memory for "someKey".
    • The response body should be a JSON object of the following form: {"key": "", "value": "" }.
    • If called with no parameters, it should return an error.
  • A "Delete" endpoint
    • It should use the POST HTTP method
    • It should be available at the /delete url path
    • The request should contain a JSON POST body consisting of a JSON entry of the following form: {"key": ""}.
    • If the key was successfully deleted, the response should be a JSON document including the key that was deleted.
    • If called with no parameters, should return an error.
    • If the key doesn't exist, it should respond with a 200, but should contain a message saying the key didn't exist.
