TypeScript 5.7 split ArrayBuffer / SharedArrayBuffer at the type level
(ArrayBuffer now exposes resizable/transfer/detached etc; SharedArrayBuffer
doesn't), and parametrized the typed-array constructors so plain
Uint8Array became Uint8Array<ArrayBufferLike>.
The renderer never uses SharedArrayBuffer, so this is type-level only —
narrowing back to ArrayBuffer at the boundaries:
- BinaryReader.readBytes() / .toArrayBuffer() return the underlying
DataView buffer; cast to ArrayBuffer.
- BinaryWriter.getBuffer() same shape.
- WsSessionCrypto.randomNonce() now returns Uint8Array<ArrayBuffer>
(it's always backed by a plain ArrayBuffer); aesGcmEncrypt/Decrypt
nonce parameter retyped accordingly so SubtleCrypto.encrypt accepts
it as BufferSource.
- ArrayBufferToBase64 now accepts Uint8Array | ArrayBufferLike directly
(pako/inflate hands back Uint8Array<ArrayBuffer> which the old
ArrayBuffer-only signature rejected).
The IRoomSession interface was missing three things that have always
existed on the RoomSession implementation:
- `password: string` — the room session's join password (used by the
reconnect flow in RoomSessionManager).
- `sendBackgroundMessage(backgroundImage, backgroundStand, backgroundOverlay, backgroundCard?)`
— sends the profile-background composer (used by the React client's
BackgroundsView).
Plus a signature relaxation:
- `sendChatMessage` / `sendShoutMessage` `chatColour` is now optional.
The implementation already accepted `undefined` (the composer forwards
it through), and every historical call site in the React client passes
only 2 args — making the 3rd optional simply types reality.
Net renderer typecheck: 26 → 23.
The change also drops 7 errors on the consumer side
(see ../Nitro-V3 typecheck after the workspace link picks this up).
CLAUDE.md gotchas updated to reflect the new interface contract.
`AssetManager.loadRoomImages()` and friends use `import.meta.glob('./assets/...', { eager: true })`
to bundle PNG assets via Vite, but TypeScript doesn't see `glob` on
ImportMeta without pulling `vite/client` — which we avoid here so the
React client (which has its own asset declarations) keeps full control.
src/globals.d.ts adds just the `glob` signature, typed for the eager
image case (`Record<string, { default: string }>`). The call sites'
existing `mod.default ?? mod` narrowing still works.
Net renderer typecheck: 29 → 26 (-3 errors).
Each workspace package was still pinning `typescript: ~5.5.x` or
`~5.8.2` in its own devDependencies even though the root bumped to 6.0.3
in 60b1143. The pins were dead (yarn 1 hoists from root) but they're
misleading when reading a single package.json. Bring them all to
`^6.0.3` to match the root.
Other:
- @thumbmarkjs/thumbmarkjs 1.8.1 → 1.9.0 (root + communication package)
- yarn.lock regenerated from a clean install (vitest 4 hoisting was
flaking on the patch vite bump; reverted vite to ^8.0.10)
Adds CLAUDE.md at the repo root: short project context for future
sessions — stack, the 12-workspace layout, the React-friendly v2.1.0
additions (`subscribe()`, `subscribeMessage()`, snapshot getters), build
scripts, and known gotchas (`SessionDataManager.getUserData` does NOT
exist; sendChat* expects 3 args; dispatchEvent is sync).
- typescript: ~5.8.2 → ^6.0.3 (matches Nitro-V3 client)
- adds @typescript/native-preview (tsgo) as TypeScript 7 preview
- new `compile:fast` script using tsgo (~7× faster: 2.5s vs 17.6s)
- tsconfig cleanup ahead of TypeScript 7 deprecations:
- removed `baseUrl` (unused: no `paths` mappings on this project)
- removed `downlevelIteration` (target ES2022 makes it a no-op)
- `moduleResolution`: "Node" → "bundler" (vite consumes the renderer)
Compile errors: 28 → 29. Net +1 because TS 6's tightened lib types flag
two pre-existing crypto calls (WsSessionCrypto.ts:43,48) and resolves one
prior false positive. All errors are in pre-existing code, unrelated to
the new event/snapshot APIs from 791b8ad.
