# fs-es6
|
||
|
|
Simple FileSystem API in the browser
|
||
|
|
> fs-es6 is a module that emulates in-browser the Node JS file system API using the FileSystem API of HTML5. fs-es6 can create, read, navigate, and write in the local file system nicely.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
```shell
|
||
|
|
npm install fs-es6
|
||
|
|
```
|
||
|
|
Here's a using the LocalStorage-backed file system:
|
||
|
|
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
The following is an example of simple use that creates a `canisLupus` folder in the `/tmp` path.
|
||
|
|
|
||
|
|
```js
|
||
|
|
import fs from 'fs-es6'
|
||
|
|
|
||
|
|
fs.mkdirSync('/tmp/canisLupus').then()
|
||
|
|
```
|
||
|
|
|
||
|
|
## Override the `fs` module
|
||
|
|
You can map your project to use this module in place of the standard Node.js fs
|
||
|
|
module by adding a _browser_ object like so into the package.json before
|
||
|
|
running the browserify command. Just make sure fs-es6 is installed as a
|
||
|
|
dependency first.
|
||
|
|
|
||
|
|
```json
|
||
|
|
"browser": {
|
||
|
|
"fs": "fs-es6"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
