### Using Cargo

If you have already installed [Cargo][cargo], you can install `wstcp` easily in the following command:

```console

$ cargo install wstcp

```

[cargo]: https://doc.rust-lang.org/cargo/

[releases]: https://github.com/sile/wstcp/releases

Examples

---------

Run `wstcp` in a terminal:

```console

$ wstcp 127.0.0.1:3000

Apr 22 23:21:20.717 INFO Starts a WebSocket proxy server, server_addr: 127.0.0.1:3000, proxy_addr: 0.0.0.0:13892

```

Run a TCP server (in this example `nc` is used) in another terminal:

```console

$ nc -l 127.0.0.1 -p 3000

```

Use [ws](https://github.com/hashrocket/ws) to launch a WebSocket client:

```console

$ ws ws://localhost:13892/

> foo # Enter "foo" and press the Enter key

```

After this, the "foo" string is displayed on the terminal running `nc`.
