api-mock-lite

Start a tiny local mock API server from a JSON file.

Why

Frontend developers often need fake APIs before backend endpoints are ready. api-mock-lite starts a simple JSON API in one command.

Install

npm install -g api-mock-lite

Usage

api-mock-lite mock.json
api-mock-lite mock.json --port 3001
api-mock-lite mock.json --host 0.0.0.0
api-mock-lite mock.json --delay 300

mock.json

{
  "GET /users": [
    { "id": 1, "name": "Tom" }
  ],
  "POST /login": {
    "status": 201,
    "body": { "token": "fake-token" }
  }
}

Then visit:

curl http://127.0.0.1:3001/users

Features
