# Debugging

The ability to debug is important for app developers. App SDK provides opt-in verbose logs, that can be enabled for specific modules.

Debug logs are implemented with [debug](https://www.npmjs.com/package/debug) package and work both in Node and Browser.

## Enabling verbose logs

Debug logs are aggregated within [namespaces](#namespaces). They can be enabled, disabled, or configured.

By default, all verbose logs are disabled.

To enable logs, use the following:

<a id="enabling-in-node-context"></a>

### Enabling in Node context

Add `DEBUG=app-sdk:{namespaces}` env variable.

<a id="example"></a>

#### Example

```shell
DEBUG=* pnpm run dev
```

For more details check [debug package](https://github.com/debug-js/debug#usage).

<a id="enabling-in-the-browser-context"></a>

### Enabling in the browser context

Set `localStorage.debug = 'app-sdk:{namepsaces}'` in your frontend code. For more details see [debug package](https://github.com/debug-js/debug#browser-support).

<a id="debug-in-iframe"></a>

#### Debug in iframe

Note, that Saleor Apps are usually hosted on a different domain than Saleor Dashboard. That means `localStorage` must be called in the context of the App's URL, not the Saleor Dashboard.

<a id="example-1"></a>

#### Example

```javascript
// In devtools console
localStorage.debug = "*";
```

<a id="namespaces"></a>

## Namespaces

Use the namespace name to enable debug logs for each module.

| Namespace name | Description |
| --- | --- |
| \\app-sdk:\* | Enable all |
| app-sdk:AppBridge | Enable [AppBridge](/developer/extending/apps/developing-apps/app-sdk/app-bridge.md) (browser only) |
| app-sdk:Middleware:\* | Enable all middlewares (node only) |
| app-sdk:APL:\* | Enable all APLs (node only) |
| app-sdk:SaleorAsyncWebhook:\* | Enable SaleorAsyncWebhook utility |
