# feathers-json-patch

Add [JSON Patch](http://jsonpatch.com/) support to any [Feathers](https://feathersjs.com) database adapter or service.

```bash

$ npm install --save feathers-json-patch

```

## Usage

### Feathers server

An example using the [feathers-memory](https://github.com/feathersjs-ecosystem/feathers-memory) adapter.

```js

const memoryService = require('feathers-memory');

const withJsonPatch = require('feathers-json-patch');

const service = withJsonPatch(memoryService);

app.use('/messages', service());

```

Another example, using service constructor:

```js

const MemoryService = require('feathers-memory').Service;

const withJsonPatch = require('feathers-json-patch');

const MyService = withJsonPatch(memoryService);

app.use('/messages', new MyService());

```

### Feathers client

```js

import feathers from '@feathersjs/client';

import { compare } from 'fast-json-patch';

const client = feathers().configure(...);

const id = 1;

const message = await client.service('/messages').get(id);

const newValues = {

  ...message,

  text: 'My updated message!',

  tags: ['info']

};

// Generate a JSON patch object

const diff = compare(message, newValues);

// Optional check, but no need to send

// a patch request if the diff has length == 0

if (diff.length) {

  client.service('/messages').patch(id, diff);

}

```

### HTTP
