# reactive-json-file 

Sync JSON mutations to disk using reactive magic!

Great for removing saving-to-disk concerns when updating a JSON object.

```js

import { openJson } from 'reactive-json-file'

// Open a JSON file

const object = openJson('./data.json')

// No need to save changes to disk, just update the object

object.name = 'John Doe'

```

## :rocket: Install

```sh

npm i reactive-json-file

```

## ⚙️ API

### openJson(filePath, options)

Open a file (eg. JSON file) and return the object

#### Options

- `throttle` `` - Milliseconds to throttle saves by. Saves are already batched at the end of every event-loop, but this adds time-based throttling.

- `fs` `` ([fs](https://nodejs.org/api/fs.html)) - Pass in a custom file-system. Defaults to native Node.js fs

- `serialize`/`deserialize` `` - Functions to serialize/deserialize the object with. eg. to save output to YAML

    ```js

    import { openJson as openYaml } from 'reactive-json-file'

    import yaml from 'js-yaml'

    const object = openYaml('./file.yaml', {

        serialize: data => yaml.dump(data),

        deserialize: string => yaml.load(string)

    })

    object.message = 'YAML!'

    ```

### closeJson(object)

Close a file to disable syncing
