JSON Server

Install JSON Server

npm install -g json-server

Create a db.json file with some data

{
  "posts": [{ "id": 1, "title": "json-server", "author": "typicode" }],
  "comments": [{ "id": 1, "body": "some comment", "postId": 1 }],
  "profile": { "name": "typicode" }
}

Start JSON Server

json-server --watch db.json

Now if you go to http://localhost:3000/posts/1, you'll get

{ "id": 1, "title": "json-server", "author": "typicode" }
