Get a full fake REST API with zero coding in less than 30 seconds (seriously)
Created with 💖 for front-end developers who need a quick back-end for prototyping and mocking.
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 --watch 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.
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 /
$ npm install -g json-server
You can use JSON Server to serve your HTML, JS and CSS, simply create a ./public
directory.
You can access your fake API from anywhere using CORS and JSONP.
You can load remote schemas:
$ json-server http://example.com/file.json
$ json-server http://jsonplaceholder.typicode.com/db
You can use JS to programmatically create data:
module.exports = function() {
var 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
If you need to add authentication, validation, rewrite or add routes, you can use the project as a module in combination with other Express middlewares.
var jsonServer = require('json-server')
var server = jsonServer.create() // Returns an Express server
var router = jsonServer.router('db.json') // Returns an Express router
server.use(jsonServer.defaults) // logger, static and cors middlewares
server.use(router) // Mount router on '/'
server.listen(3000)
For an in-memory database, you can pass an object to jsonServer.route()
.
Please note also that jsonServer.router()
can be used in existing Express projects.
You can deploy JSON Server. For example, JSONPlaceholder is an online fake API powered by JSON Server and running on Heroku.
