`@helia/unixfs` is an implementation of a UnixFS filesystem compatible with Helia.

See the [API docs](https://ipfs.github.io/helia/modules/_helia_unixfs.html) for all available operations.

## Example - Creating files and directories

```typescript
import { createHelia } from 'helia'
import { unixfs } from '@helia/unixfs'

const helia = await createHelia()
const fs = unixfs(helia)

// create an empty dir and a file, then add the file to the dir
const emptyDirCid = await fs.addDirectory()
const fileCid = await fs.addBytes(Uint8Array.from([0, 1, 2, 3]))
const updateDirCid = await fs.cp(fileCid, emptyDirCid, 'foo.txt')

// or doing the same thing as a stream
for await (const entry of fs.addAll([{
  path: 'foo.txt',
  content: Uint8Array.from([0, 1, 2, 3])
}])) {
  console.info(entry)
}
```

## Example - Recursively adding a directory

Node.js-compatibly environments only:

```typescript
import { createHelia } from 'helia'
import { unixfs } from '@helia/unixfs'
import { globSource } from '@helia/unixfs'

const helia = await createHelia()
const fs = unixfs(helia)

for await (const entry of fs.addAll(globSource('path/to/containing/dir', 'glob-pattern'))) {
  console.info(entry)
}
```

## Example - Adding files and directories in the browser

Uses [@cypsela/browser-source](https://github.com/cypsela/browser-source) to read [FileList](https://developer.mozilla.org/en-US/docs/Web/API/FileList), [FileSystemEntry](https://developer.mozilla.org/en-US/docs/Web/API/FileSystemEntry), and [FileSystemHandle](https://developer.mozilla.org/en-US/docs/Web/API/FileSystemHandle) files and directories.

Instances of these data types are available from [\<input type="file" />](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/input/file) elements, [drag-and-drop events](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/drop_event), and window methods like [showOpenFilePicker](https://developer.mozilla.org/en-US/docs/Web/API/Window/showOpenFilePicker).

```typescript
import { createHelia } from 'helia'
import { unixfs } from '@helia/unixfs'
import { fileListSource, fsEntrySource, fsHandleSource } from '@cypsela/browser-source'

const helia = await createHelia()
const fs = unixfs(helia)

// get FileList from <input type="file" /> elements
const fileList = {} as FileList

for await (const entry of fs.addAll(fileListSource(fileList))) {
  console.info(entry)
}

// get FileSystemEntry from drag and drop events
const fileEntry = {} as FileSystemEntry

for await (const entry of fs.addAll(fsEntrySource(fileEntry))) {
  console.info(entry)
}

// get FileSystemHandle from drag and drop events or window methods
const fileHandle = {} as FileSystemHandle

for await (const entry of fs.addAll(fsHandleSource(fileHandle))) {
  console.info(entry)
}
```

# Install

```console
$ npm i @helia/unixfs
```

## Browser `<script>` tag

Loading this module through a script tag will make its exports available as `HeliaUnixfs` in the global namespace.

```html
<script src="https://unpkg.com/@helia/unixfs/dist/index.min.js"></script>
```
