Package Exports
- json-server
- json-server/package.json
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-server) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
JSON Server

Get a full fake REST API with zero coding in less than 30 seconds (seriously)
Created with <3 for front-end developers who need a quick back-end for prototyping and mocking.
Example
Create a db.json
file
{
"posts": [
{
"id": 1,
"title": "json-server",
"author": "typicode"
}
],
"comments": [
{
"id": 1,
"body": "some comment",
"postId": 1
}
]
}
Start JSON Server
$ json-server db.json
Now if you go to http://localhost:3000/posts/1, you'll get
{
"id": 1,
"title": "json-server",
"author": "typicode"
}
Also, if you make POST, PUT, PATCH or DELETE requests, changes will be automatically saved to db.json
using lowdb
Routes
Based on the previous db.json
file, here are all the available routes. If you need more customization, you can use the project as a module.
GET /posts
GET /posts/1
GET /posts/1/comments
GET /posts?title=json-server&author=typicode
POST /posts
PUT /posts/1
PATCH /posts/1
DELETE /posts/1
To slice resources, add _start
and _end
or _limit
(an X-Total-Count
header is included in the response).
GET /posts?_start=20&_end=30
GET /posts/1/comments?_start=20&_end=30
To sort resources, add _sort
and _order
(ascending order by default).
GET /posts?_sort=views&_order=DESC
GET /posts/1/comments?_sort=votes&_order=ASC
To make a full-text search on resources, add q
.
GET /posts?q=internet
Returns database.
GET /db
Returns default index file or serves ./public
directory.
GET /
Install
$ npm install -g json-server
Extras
Static file server
You can use JSON Server to serve your HTML, JS and CSS, simply create a ./public
directory.
Access from anywhere
You can access your fake API from anywhere using CORS and JSONP.
Remote schema
You can load remote schemas:
$ json-server http://example.com/file.json
$ json-server http://jsonplaceholder.typicode.com/db
JS file support
You can use JS to programmatically create data:
module.exports = function() {
data = { users: [] }
// Create 1000 users
for (var i = 0; i < 1000; i++) {
data.users.push({ id: i, name: 'user' + i })
}
return data
}
$ json-server index.js
Module
var jsonServer = require('json-server')
// Express server
var server = jsonServer.create()
// Default middlewares (logger, public, cors)
server.use(jsonServer.defaults)
// Add other Express middlewares if needed (authentication, redirections, ...)
// ...
// Express router
server.use(jsonServer.router('db.json'))
server.listen(3000)
For an in-memory database, you can pass an object to jsonServer.route()
.
Please note also that you can use the jsonServer.router()
in existing Express servers.
Deployment
You can deploy JSON Server. For example, JSONPlaceholder is an online fake API powered by JSON Server and running on Heroku.
