Create a db.json or db.json5 file

    { "id": "2", "title": "another title", "views": 200 }
  ],
  "comments": [
    { "id": "1", "text": "a comment about post 1", "postId": "1" },
    { "id": "2", "text": "another comment about post 1", "postId": "1" }
  ],
  "profile": {
    "name": "typicode"
  }
}

View db.json5 example

{
  posts: [
    { id: '1', title: 'a title', views: 100 },
    { id: '2', title: 'another title', views: 200 },
  ],
  comments: [
    { id: '1', text: 'a comment about post 1', postId: '1' },
    { id: '2', text: 'another comment about post 1', postId: '1' },
  ],
  profile: {
    name: 'typicode',
  },
}

Serving static files

If you create a ./public directory, JSON Server will serve its content in addition to the REST API.

You can also add custom directories using -s/--static option.

json-server -s ./static
json-server -s ./static -s ./node_modules

Notable differences with v0.17

id is always a string and will be generated for you if missing
use _per_page with _page instead of _limitfor pagination
use Chrome's Network tab > throtling to delay requests instead of --delay CLI option
