{
"posts": [
{
"id": 1,
"title": "json-server",
"author": "typicode"
},
{
"id": 2,
"title": "json-server",
"author": "typicode2"
},
{
"id": 3,
"title": "json-server",
"author": "typicode3"
},
{
"id": 4,
"title": "fy-server",
"author": "typicode3"
},
{
"id": 5,
"title": "fy-server",
"author": "typicode3"
}
],
"comments": [
{
"id": 1,
"body": "some comment",
"postId": 1

{
"id": 3,
"body": "some comment",
"postId": 2
}
],
"profile": {
