# Debugging

When developing a Ray Library, you may find it necessary to debug the data being sent to the Ray app.

You may use the following third-party package to intercept and display the data being sent from your code to the Ray app:

[permafrost-dev/ray-proxy](https://github.com/permafrost-dev/ray-proxy)

## Usage

First, set your port in the Ray app to `23516` in the preferences.

Next, you need to start the proxy application.

The easiest way to run `ray-proxy` is with `npx`:

```
 npx ray-proxy
```

You can also install `ray-proxy` as you would any other npm package:

```
 npm install ray-proxy --save-dev

./node_modules/.bin/ray-proxy
```

Once you start sending Ray messages, you'll see the raw payloads being sent in the proxy, along with statistics!

## Debug without breaking your flow

Ray keeps all your debug output neatly organized in a dedicated desktop app.
