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" }
}
json-server --watch db.json
Tenemos 3 categorías, posts, comments y profile.
Para ver posts:
curl http://localhost:3000/posts
[
  {
    "id": 1,
    "title": "json-server",
    "author": "typicode"
  }
]
