## Summary
Upgrades the workspace to TypeScript 6.0.3 and applies the compiler,
type, and build configuration changes required to preserve package
layouts and existing runtime behavior, apart from correcting the HTTP
status field used for deployment connection errors.
## Compatibility
- Centralizes TypeScript 6.0.3 through the pnpm workspace catalog.
- Replaces compiler options and module resolution modes that TypeScript
6 no longer accepts.
- Restores explicit Node types where TypeScript 6 no longer includes
them transitively.
- Adds explicit declaration build roots that preserve each package's
existing output layout.
- Patches tsup to stop injecting the removed `baseUrl` option during
declaration builds.
- Uses type-only assertions for stricter typed-array and stream
definitions without changing runtime behavior.
- Reads the EventSource v3 HTTP status from `code`, so deployment
connection errors include it correctly.
- Keeps standalone CLI compatibility fixtures pinned to their existing
TypeScript version and lockfiles.
`turbo run typecheck` and the complete PR test suite are green.
Once this is merged, oxlint is at a pretty sensible baseline.
**Enable `no-unused-vars`, `typescript/consistent-type-imports`, and
`import/no-duplicates` lint rules**
Turns on three previously-disabled oxlint rules across the monorepo and
fixes all violations:
- **`no-unused-vars`** – enabled as an error with standard ignore
patterns: unused function arguments are ignored by default (`args:
"none"`), variables/caught errors/destructured array elements prefixed
with `_` are allowed, and rest siblings are permitted.
- **`typescript/consistent-type-imports`** – enforced as an error; all
type-only imports now use the `import type` syntax.
- **`import/no-duplicates`** – enforced as an error; duplicate import
statements from the same module have been merged.
The remaining commits clean up the violations found across the codebase:
removing unused variables/imports/type aliases, adding `_` prefixes to
intentionally unused bindings, fixing duplicate imports, and converting
value imports to `import type` where appropriate.
Bundle superjson and its dependency (copy-anything) during build to
avoid
ERR_REQUIRE_ESM errors on Node.js versions that don't support
require(ESM)
by default (< 22.12.0) and AWS Lambda which intentionally disables it.
- Add scripts/bundle-superjson.mjs to bundle superjson with esbuild
- Update build script to bundle vendor files before tshy compilation
- Move superjson from dependencies to devDependencies
- Update imports to use vendored bundles
