| `@elata-biosciences/eeg-web`           | modern browser with WebAssembly            | `>= 20` | browser usage depends on serving packaged WASM assets |
| `@elata-biosciences/eeg-web-ble`       | Chrome or Edge with Web Bluetooth          | `>= 20` | depends on `@elata-biosciences/eeg-web`               |
| `@elata-biosciences/rppg-web`          | modern browser with camera and WebAssembly | `>= 20` | packaged WASM assets must be reachable by the browser |

## Browser Support

| Workflow                            | Chrome / Edge               | Safari macOS  | Safari iOS                        | Notes                            |
| ----------------------------------- | --------------------------- | ------------- | --------------------------------- | -------------------------------- |
| `create-elata-demo`                 | n/a                         | n/a           | n/a                               | scaffolder runs in Node          |
| EEG WASM with `eeg-web`             | Supported                   | Supported     | Supported                         | requires packaged `wasm/` assets |
| Muse browser BLE with `eeg-web-ble` | Supported in secure context | Not supported | Not supported                     | requires Web Bluetooth           |
| rPPG with `rppg-web`                | Supported                   | Supported     | Supported with camera permissions | requires packaged `pkg/` assets  |

***

## Web Bluetooth Expectations

* Use Chrome or Edge.
* Run on `https://` or `localhost`.
* Enable Bluetooth on the machine.
* Expect Safari and iOS browser BLE to be unsupported for this workflow.

<Warning>
  `eeg-web-ble` requires Web Bluetooth and an `https://` origin or `localhost`. Safari and iOS do not support Web Bluetooth for Muse browser workflows.
</Warning>

***

## Supported Device Classes

* Muse 2 and Muse S classic BLE devices
* Muse S Athena protocol v2 devices
* The synthetic Muse-compatible BLE bridge used for testing

***

## Safari And iOS Notes

* `eeg-web` can be used as a browser-side WASM package on Safari when your app serves its packaged assets correctly.
* `eeg-web-ble` is not a Safari or iOS browser workflow. Use a native app shell with CoreBluetooth or a companion bridge app streaming frames over WebSocket.
* `rppg-web` can run on Safari and iOS, but camera permissions and packaged WASM delivery still need to be correct.

***

## Package Manager Notes

Generated demo apps work with `pnpm` or `npm`. This repo prefers `pnpm` for
local development.

If you scaffold a demo app inside another `pnpm` workspace and do not add it to
that workspace, use:

<CodeGroup>
  ```bash pnpm theme={null}
  pnpm --dir my-app --ignore-workspace install
  pnpm --dir my-app --ignore-workspace run dev
  ```

  ```bash npm theme={null}
  cd my-app
  npm install
  npm run dev
  ```
</CodeGroup>
