# File server

## Concepts

- Use the Deno standard library
  [file_server.ts](https://deno.land/std@$STD_VERSION/http/file_server.ts) to
  run your own file server and access your files from your web browser.
- Run [Deno install](../tools/script_installer.md) to install the file server
  locally.

## Example

Serve a local directory via HTTP. First install the remote script to your local
file system. This will install the script to the Deno installation root's bin
directory, e.g. `/home/alice/.deno/bin/file_server`.

```shell
deno install --allow-net --allow-read https://deno.land/std@$STD_VERSION/http/file_server.ts
```

You can now run the script with the simplified script name. Run it:

```shell
$ file_server .
Downloading https://deno.land/std@$STD_VERSION/http/file_server.ts...
[...]
HTTP server listening on http://0.0.0.0:4507/
```

Now go to [http://0.0.0.0:4507/](http://0.0.0.0:4507/) in your web browser to
see your local directory contents.

## Help

Help and a complete list of options are available via:

```shell
file_server --help
```

Example output:

```
