# Lightpanda

> Use the lightpanda build extension to add Lightpanda browser to your project

To use the Lightpanda browser in your project, add the extension to your `trigger.config.ts` file:

```ts trigger.config.ts theme={"theme":"css-variables"}
import { defineConfig } from "@trigger.dev/sdk";
import { lightpanda } from "@trigger.dev/build/extensions/lightpanda";

export default defineConfig({
  project: "<project ref>",
  build: {
    extensions: [lightpanda()],
  },
});
```

## Options

* `version`: The version of the browser to install. Default: `"latest"`.
* `disableTelemetry`: Whether to disable telemetry. Default: `false`.

For example:

```ts trigger.config.ts theme={"theme":"css-variables"}
import { defineConfig } from "@trigger.dev/sdk";
import { lightpanda } from "@trigger.dev/build/extensions/lightpanda";

export default defineConfig({
  project: "<project ref>",
  build: {
    extensions: [
      lightpanda({
        version: "nightly",
        disableTelemetry: true,
      }),
    ],
  },
});
```

## Development

When running in dev, you will first have to download the Lightpanda browser binary and make sure it's in your `PATH`. See [Lightpanda's installation guide](https://lightpanda.io/docs/getting-started/installation).
