# Packages

The Packages tab lists every library your app depends on, organised into three cards:

<table><thead><tr><th width="217.18603515625">Card</th><th>What it shows</th></tr></thead><tbody><tr><td><strong>Frontend packages</strong></td><td>Installed NPM packages for your React / TypeScript frontend</td></tr><tr><td><strong>Backend packages</strong></td><td>Installed Python packages for your FastAPI backend</td></tr><tr><td><strong>Build artifacts</strong></td><td>Compiled build output</td></tr></tbody></table>

Each card shows package names and versions, with controls to add or remove packages.

## How packages are managed

The Riff agent installs packages automatically when it needs a library to complete a build task — you usually do not need to think about this.

If you need a specific package that the agent has not installed, ask it in chat: *"Install the pandas library"* or *"Add a charting library for the frontend."*

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.riff.ai/reference/app-builder/packages.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
