# Integrate raavl

Add a working audio waveform player using the application's existing framework,
design, and controls. Keep additions within the requested audio experience.

## Read the current contract

When the user provides a raavl documentation URL, read its `/llms.txt` index and
fetch only the relevant Markdown pages. The full reference is `/llms-full.txt`.
When a raavl checkout is available, read the matching files in
`docs/content/docs/` and inspect the exported types in `src/` as needed.

If neither is available, the maintained guides are in the raavl repository:

- [Quickstart](https://github.com/raptisj/raavl/blob/main/docs/content/docs/quickstart.mdx): installation and a first JavaScript or React player.
- [Sources](https://github.com/raptisj/raavl/blob/main/docs/content/docs/sources.mdx): URL, File/Blob, borrowed media, and supplied peaks.
- [Player](https://github.com/raptisj/raavl/blob/main/docs/content/docs/player.mdx), [waveform](https://github.com/raptisj/raavl/blob/main/docs/content/docs/waveform.mdx), and [React](https://github.com/raptisj/raavl/blob/main/docs/content/docs/react.mdx): use the reference matching the selected API.
- [Styling](https://github.com/raptisj/raavl/blob/main/docs/content/docs/styling.mdx): CSS tokens and validated JSON themes.
- [Annotations](https://github.com/raptisj/raavl/blob/main/docs/content/docs/annotations.mdx) and [optional modules](https://github.com/raptisj/raavl/blob/main/docs/content/docs/modules.mdx): read when the requested task needs them.
- [State and errors](https://github.com/raptisj/raavl/blob/main/docs/content/docs/errors.mdx): separate playback and visualization failures.

Match documentation to the installed version. If documentation cannot be fetched,
use the available checkout or installed declarations; report missing information
instead of inventing APIs. Historical proposals under `docs/design/` may describe
unimplemented features.

## Choose an integration

Inspect the consuming app's package manager, package boundaries, framework,
React version, asset serving, existing player code, and design conventions.

- For React with React DOM, use `Waveform` and hooks from `raavl/react`.
  In Next.js App Router, place the interactive integration in a client component.
- For vanilla JavaScript or other frameworks, use `createPlayer` and
  `mountWaveform` through browser lifecycle hooks.
  Preserve the app's framework version unless upgrading it is part of the task.
- Reuse an application-owned media element when the app already owns playback.
  That source requires supplied peaks or `waveform: { kind: 'none' }`.

Follow the quickstart's installation command using the consuming application's
package manager. Match the installed package version to the documentation and
reuse an existing compatible dependency when present.

## Build the requested experience

Use the quickstart and API references for code. Add a waveform and the controls
the user needs, using the app's existing components, colors, and spacing.

- Supply a real audio URL, File/Blob, or borrowed media source with a stable ID.
  Demo recordings from the documentation site are not installed package assets.
- Handle source loading, waveform preparation, buffering, and playback errors
  separately. Metadata readiness does not guarantee a waveform or buffered audio.
- Start playback from a user gesture and handle rejected `play()` promises.
- Keep accessible names, real buttons, and keyboard/touch seeking available.
- Prefer supplied peaks for long recordings instead of decoding the entire audio
  solely for visualization. Verify source ID, revision, and duration match.
- Add a theme, annotations, timeline, minimap, history, or snapping only when the
  requested experience calls for it. Application code owns persistence.

## Preserve ownership

In React, choose an owned `source` or a borrowed `player`, never both. An owned
`Waveform` cleans up its own resources; a supplied player or annotation store
remains application-owned. Keep large peak buffers, Files, and request objects
stable; update source revisions when asset data changes.

With the DOM API, unsubscribe listeners and dispose mounted accessories and
views before the owned player/store during teardown. Disposing a view does not
dispose its borrowed player. Borrowed media must remain application-owned.

All time commands use seconds except `seekFraction()`, which takes a fraction
in `[0, 1]`. After external CSS color changes, call `view.refreshTheme()` or
change React's `themeVersion`; Canvas needs a redraw to reflect computed colors.

## Verify and report

Run checks appropriate to the consuming app and exercise real playback,
pause/resume, pointer and keyboard seeking, source replacement, visible errors,
and component cleanup. Verify waveform CORS separately from native playback for
cross-origin audio. When a browser, agent environment, or audio source is
unavailable, identify the unverified behavior explicitly.

Report the integration chosen, changed files, commands to run, and verification
results. Keep browser-dependent timing claims accurate: range playback uses
best-effort media timing. Recording, spectrograms, sample-accurate playback, and
automatic backend storage are not implemented.
