| ## Todos | ||
| - [x] BDecode implementation | ||
| - [ ] Magnet URI scheme (should be trivial) | ||
| - [ ] Convert all `makeXXXTransformStream` functional closure states to [`transformer`](https://developer.mozilla.org/en-US/docs/Web/API/TransformStream/TransformStream#:~:text=Parameters-,transformer,-Optional) class states (should be trivial) | ||
| - [ ] `ArrayKeyedMap` with `ArrayBuffer` keys (use proxy or drop suppport?) | ||
| - [ ] Convert typescript `Enum`s to `Union`s (need investigation) | ||
| - [ ] Other type related issues (need investigation) | ||
| - [ ] Bundleless entry (need investigation) | ||
| - [ ] Support other common BEPs (need investigation) | ||
| - [ ] Add tests | ||
| - [ ] Add demo page | ||
