Stop Building APIs from Scratch for Prototypes — Use This Instead

Every time I start a new frontend project, the same problem hits: the backend isn't ready yet. I used to build minimal Express/Flask servers just to have something to fetch from. That's at least 30 minutes of boilerplate before writing any frontend code. Then I built a tool that creates a full REST API from a JSON file in 10 seconds. The Problem You're building a React dashboard. You need: GET /users — list of users GET /users/1 — single user POST /users — create user PUT /users/1 — update user DELETE /users/1 — delete user Plus filtering, pagination, and sorting. Setting this up with Express: 30-60 minutes. Setting this up with json-api-mocker: 10 seconds. How It Works Create a JSON file with your data: { "users": [ {"id": 1, "name": "Alice", "email": "[email protected]", "role": "admin"}, {"id": 2, "name": "Bob", "email": "[email protected]", "role": "user"} ], "posts": [ {"id": 1, "userId": 1, "title": "Hello World"}, {"id": 2, "userId": 2, "title": "Python Tips"} ] } Run the mocker: pip in
