# `patchFs(vol[, fs])` |
|
|
|
Rewrites Node's filesystem module `fs` with *fs-like* object. |
|
|
|
- `vol` - fs-like object |
|
- `fs` *(optional)* - a filesystem to patch, defaults to `require('fs')` |
|
|
|
```js |
|
import {patchFs} from 'fs-monkey'; |
|
|
|
const myfs = { |
|
readFileSync: () => 'hello world', |
|
}; |
|
|
|
patchFs(myfs); |
|
console.log(require('fs').readFileSync('/foo/bar')); // hello world |
|
``` |
|
|
|
You don't need to create *fs-like* objects yourself, use [`memfs`](https://github.com/streamich/memfs) |
|
to create a virtual filesystem for you: |
|
|
|
```js |
|
import {vol} from 'memfs'; |
|
import {patchFs} from 'fs-monkey'; |
|
|
|
vol.fromJSON({'/dir/foo': 'bar'}); |
|
patchFs(vol); |
|
console.log(require('fs').readdirSync('/')); // [ 'dir' ] |
|
```
