Description: Get a full fake REST API with zero coding in less than 30 seconds
Author: Typicode
Latest version: 0.16.2

# JSON Server [![](https://travis-ci.org/typicode/json-server.svg?branch=master)](https://travis-ci.org/typicode/json-server) [![](https://badge.fury.io/js/json-server.svg)](http://badge.fury.io/js/json-server)

# Why we fork?
json-server is forked from [typicode/json-server](https://github.com/typicode/json-server)

So basically the reason why we fork?
- Adapt to change API standard to fit our need
- Some importand features we need support? (TBD)

High level changes we made:
- Change sort, use plus sign (+), minus sign (-) to identify sort direction
- Remove slice feature
- Simplify relation operation, merge _embed and _expand to _include
- Change pagination response, to use meta root element in JSON response instead of X-Total-Count header
- Keep name convention consistend, q changed to _q. all reserved param name starts with _

ToDo:
- mock action response instead of empty response (collection and member)

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.

## Getting started

Install JSON Server 

```
npm install -g json-server
```

Create a `db.json` file with some data

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

Start JSON Server

```bash
json-server --watch db.json
```

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

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

Also when doing requests, it's good to know that:

- If you make POST, PUT, PATCH or DELETE requests, changes will be automatically and safely saved to `db.json` using [lowdb](https://github.com/typicode/lowdb).
- Your request body JSON should be object enclosed, just like the GET output. (for example `{"name": "Foobar"}`)
- Id values are not mutable. Any `id` value in the body of your PUT or PATCH request will be ignored. Only a value set in a POST request will be respected, but only if not already taken.
- A POST, PUT or PATCH request should include a `Content-Type: application/json` header to use the JSON in the request body. Otherwise it will result in a 200 OK but without changes being made to the data.

## Routes

Based on the previous `db.json` file, here are all the default routes. You can also add [other routes](#add-custom-routes) using `--routes`.

### Plural routes

```
GET    /posts
GET    /posts/1
POST   /posts
PUT    /posts/1
PATCH  /posts/1
DELETE /posts/1
```

### Singular routes

```
GET    /profile
POST   /profile
PUT    /profile
PATCH  /profile
```

### Filter

Use `.` to access deep properties

```
GET /posts?title=json-server&author=typicode
GET /posts?id=1&id=2
GET /comments?author.name=typicode
```

### Paginate

Use `_page` and optionally `_limit` to paginate returned data.

```
GET /posts?_page=7
GET /posts?_page=7&_limit=20
```

_10 items are returned by default_

### Sort

Add `_sort`, ascending order by default)

```
GET /posts?_sort=+view                // + means asc
GET /posts/1/comments?_sort=-votes    // - means desc
```

For multiple fields, use the following format:

```
GET /posts?_sort=+user,-views
```

_Works exactly as [Array.slice](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/slice) (i.e. `_start` is inclusive and `_end` exclusive)_

### Operators

Add `_gte` or `_lte` for getting a range

```
GET /posts?views_gte=10&views_lte=20
```

Add `_ne` to exclude a value

```
GET /posts?id_ne=1
```

Add `_like` to filter (RegExp supported)

```
GET /posts?title_like=server
```

### Full-text search

Add `_q`

```
GET /posts?q=internet
```

### Relationships

To include children resources, add `_include`

```
GET /posts?_include=comments
GET /posts/1?_include=comments
```

To include parent resource, add `_include`

```
GET /comments?_include=post
GET /comments/1?_include=post
```

To get or create nested resources (by default one level, [add custom routes](#add-custom-routes) for more)

```
GET  /posts/1/comments
POST /posts/1/comments
```

### Database

```
GET /db
```

### Homepage

Returns default index file or serves `./public` directory

```
GET /
```

## Extras

### Static file server

You can use JSON Server to serve your HTML, JS and CSS, simply create a `./public` directory
or use `--static` to set a different static files directory.

```bash
mkdir public
echo 'hello world' > public/index.html
json-server db.json
```

```bash
json-server db.json --static ./some-other-dir
```

### Alternative port

You can start JSON Server on other ports with the `--port` flag:

```bash
$ json-server --watch db.json --port 3004
```

### Access from anywhere

You can access your fake API from anywhere using CORS and JSONP.

### Remote schema

You can load remote schemas.

```bash
$ json-server http://example.com/file.json
$ json-server http://jsonplaceholder.typicode.com/db
```

### Generate random data

Using JS instead of a JSON file, you can create data programmatically.

```javascript
// index.js
module.exports = () => {
  const data = { users: [] }
  // Create 1000 users
  for (let i = 0; i < 1000; i++) {
    data.users.push({ id: i, name: `user${i}` })
  }
  return data
}
```

```bash
$ json-server index.js
```

__Tip__ use modules like [Faker](https://github.com/Marak/faker.js), [Casual](https://github.com/boo1ean/casual), [Chance](https://github.com/victorquinn/chancejs) or [JSON Schema Faker](https://github.com/json-schema-faker/json-schema-faker).

### HTTPS

There are many ways to set up SSL in development. One simple way is to use [hotel](https://github.com/typicode/hotel).

### Add custom routes

Create a `routes.json` file. Pay attention to start every route with `/`.

```json
{
  "/api/*": "/$1",
  "/:resource/:id/show": "/:resource/:id",
  "/posts/:category": "/posts?category=:category",
  "/articles\\?id=:id": "/posts/:id"
}
```

Start JSON Server with `--routes` option.

```bash
json-server db.json --routes routes.json
```

Now you can access resources using additional routes.

```sh
/api/posts # → /posts
/api/posts/1  # → /posts/1
/posts/1/show # → /posts/1
/posts/javascript # → /posts?category=javascript
/articles?id=1 # → /posts/1
```

### Add middlewares

You can add your middlewares from the CLI using `--middlewares` option:

```js
// hello.js
module.exports = (req, res, next) => {
  res.header('X-Hello', 'World')
  next()
}
```

```bash
json-server db.json --middlewares ./hello.js
json-server db.json --middlewares ./first.js ./second.js
```

  json-server file.js
  json-server http://example.com/db.json

https://github.com/typicode/json-server
```

You can also set options in a `json-server.json` configuration file.

```json
{
  "port": 3000
}
```

### Module

If you need to add authentication, validation, or __any behavior__, you can use the project as a module in combination with other Express middlewares.

#### Simple example

```sh
$ npm install json-server --save-dev
```

```js
// server.js
const jsonServer = require('json-server')
const server = jsonServer.create()
const router = jsonServer.router('db.json')
const middlewares = jsonServer.defaults()

server.use(middlewares)
server.use(router)
server.listen(3000, () => {
  console.log('JSON Server is running')
})
```

```sh
$ node server.js
```

The path you provide to the `jsonServer.router` function  is relative to the directory from where you launch your node process. If you run the above code from another directory, it’s better to use an absolute path:

```js
const path = require('path')
const router = jsonServer.router(path.join(__dirname, 'db.json'))
```

For an in-memory database, simply pass an object to `jsonServer.router()`.

Please note also that `jsonServer.router()` can be used in existing Express projects.

#### Custom routes example

Let's say you want a route that echoes query parameters and another one that set a timestamp on every resource created.

```js
const jsonServer = require('json-server')
const server = jsonServer.create()
const router = jsonServer.router('db.json')
const middlewares = jsonServer.defaults()

// Set default middlewares (logger, static, cors and no-cache)
server.use(middlewares)

// Add custom routes before JSON Server router
server.get('/echo', (req, res) => {
  res.jsonp(req.query)
})

// To handle POST, PUT and PATCH you need to use a body-parser
// You can use the one used by JSON Server
server.use(jsonServer.bodyParser)
server.use((req, res, next) => {
  if (req.method === 'POST') {
    req.body.createdAt = Date.now()
  }
  // Continue to JSON Server router
  next()
})

// Use default router
server.use(router)
server.listen(3000, () => {
  console.log('JSON Server is running')
})
```

#### Access control example

```js
const jsonServer = require('json-server')
const server = jsonServer.create()
const router = jsonServer.router('db.json')
const middlewares = jsonServer.defaults()

server.use(middlewares)
server.use((req, res, next) => {
 if (isAuthorized(req)) { // add your authorization logic here
   next() // continue to JSON Server router
 } else {
   res.sendStatus(401)
 }
})
server.use(router)
server.listen(3000, () => {
  console.log('JSON Server is running')
})
```
#### Custom output example

To modify responses, overwrite `router.render` method:

```javascript
// In this example, returned resources will be wrapped in a body property
router.render = (req, res) => {
  res.jsonp({
    body: res.locals.data
  })
}
```

You can set your own status code for the response:


```javascript
// In this example we simulate a server side error response
router.render = (req, res) => {
  res.status(500).jsonp({
    error: "error message here"
  })
}
```

#### Rewriter example

To add rewrite rules, use `jsonServer.rewriter()`:

```javascript
// Add this before server.use(router)
server.use(jsonServer.rewriter({
  '/api/*': '/$1',
  '/blog/:resource/:id/show': '/:resource/:id'
}))
```

#### Mounting JSON Server on another endpoint example

Alternatively, you can also mount the router on `/api`.

```javascript
server.use('/api', router)
```

#### API

__`jsonServer.create()`__

Returns an Express server.

__`jsonServer.defaults([options])`__

Returns middlewares used by JSON Server.

* options
  * `static` path to static files
  * `logger` enable logger middleware (default: true)
  * `bodyParser` enable body-parser middleware (default: true)
  * `noCors` disable CORS (default: false)
  * `readOnly` accept only GET requests (default: false)

__`jsonServer.router([path|object])`__

Returns JSON Server router.

### Deployment

You can deploy JSON Server. For example, [JSONPlaceholder](http://jsonplaceholder.typicode.com) is an online fake API powered by JSON Server and running on Heroku.
