makeDir()

makeDir(path: string, opts?: FilesystemRequestOpts): Promise<boolean>

Create a new directory and all directories along the way if needed on the specified path.

Parameters

Parameter	Type	Description
`path`	`string`	path to a new directory. For example ‘/dirA/dirB’ when creating ‘dirB’.
`opts`?	`FilesystemRequestOpts`	connection options.

Returns

Promise<boolean> true if the directory was created, false if it already exists.

read()

read(path, opts)

read(path: string, opts?: FilesystemRequestOpts & object): Promise<string>

Read file content as a string. You can pass text, bytes, blob, or stream to opts.format to change the return type.

Parameters

Parameter	Type	Description
`path`	`string`	path to the file.
`opts`?	`FilesystemRequestOpts` & `object`	connection options.

Returns

Promise<string> file content as string

read(path, opts)

read(path: string, opts?: FilesystemRequestOpts & object): Promise<Uint8Array>

Read file content as a Uint8Array. You can pass text, bytes, blob, or stream to opts.format to change the return type.

Parameters

Parameter	Type	Description
`path`	`string`	path to the file.
`opts`?	`FilesystemRequestOpts` & `object`	connection options.

Returns

Promise<Uint8Array> file content as Uint8Array

read(path, opts)

read(path: string, opts?: FilesystemRequestOpts & object): Promise<Blob>

Read file content as a Blob. You can pass text, bytes, blob, or stream to opts.format to change the return type.

Parameters

Parameter	Type	Description
`path`	`string`	path to the file.
`opts`?	`FilesystemRequestOpts` & `object`	connection options.

Returns

Promise<Blob> file content as Blob

read(path, opts)

read(path: string, opts?: FilesystemRequestOpts & object): Promise<ReadableStream<Uint8Array>>

Read file content as a ReadableStream. You can pass text, bytes, blob, or stream to opts.format to change the return type.

Parameters

Parameter	Type	Description
`path`	`string`	path to the file.
`opts`?	`FilesystemRequestOpts` & `object`	connection options.

Returns

Promise<ReadableStream<Uint8Array>> file content as ReadableStream

remove()

remove(path: string, opts?: FilesystemRequestOpts): Promise<void>

Remove a file or directory.

Parameters

Parameter	Type	Description
`path`	`string`	path to a file or directory.
`opts`?	`FilesystemRequestOpts`	connection options.

Returns

Promise<void>

rename()

rename(
   oldPath: string, 
   newPath: string, 
opts?: FilesystemRequestOpts): Promise<EntryInfo>

Rename a file or directory.

Parameters

Parameter	Type	Description
`oldPath`	`string`	path to the file or directory to rename.
`newPath`	`string`	new path for the file or directory.
`opts`?	`FilesystemRequestOpts`	connection options.

Returns

Promise<EntryInfo> information about renamed file or directory.

watchDir()

watchDir(
   path: string, 
   onEvent: (event: FilesystemEvent) => void | Promise<void>, 
opts?: WatchOpts): Promise<WatchHandle>

Start watching a directory for filesystem events.

Parameters

Parameter	Type	Description
`path`	`string`	path to directory to watch.
`onEvent`	(`event`: `FilesystemEvent`) => `void` \| `Promise`<`void`>	callback to call when an event in the directory occurs.
`opts`?	`WatchOpts`	connection options.

Returns

Promise<WatchHandle> WatchHandle object for stopping watching directory.

write()

write(
   path: string, 
   data: string | ArrayBuffer | Blob | ReadableStream<any>, 
opts?: FilesystemRequestOpts): Promise<EntryInfo>

Write content to a file. Writing to a file that doesn’t exist creates the file. Writing to a file that already exists overwrites the file. Writing to a file at path that doesn’t exist creates the necessary directories.

Parameters

Parameter	Type	Description
`path`	`string`	path to file.
`data`	`string` \| `ArrayBuffer` \| `Blob` \| `ReadableStream`<`any`>	data to write to the file. Data can be a string, `ArrayBuffer`, `Blob`, or `ReadableStream`.
`opts`?	`FilesystemRequestOpts`	connection options.

Returns

Promise<EntryInfo> information about the written file
