Upgrades the monorepo to TypeScript 7.0.2, released 2026-07-08. `tsc` is now the native Go compiler ([announcement](https://devblogs.microsoft.com/typescript/announcing-typescript-7-0/)) — full turbo typecheck drops from ~56s to ~19s locally. TS 7.0 ships **without a programmatic API** (it lands in 7.1), so this uses Microsoft's recommended side-by-side setup: the `typescript` name resolves to `@typescript/typescript6` (the 6.0 API republished) for API consumers — typescript-eslint and Next.js build typechecking — while `@typescript/native` (the real `typescript@7.0.2`) owns the `tsc` bin that typecheck scripts run. Exactly one version of each is in the lockfile; nothing imports the native package as a library. When 7.1 + tool support lands we can collapse back to a single `typescript` dep in the catalog. **Changed:** - `pnpm-workspace.yaml`: catalog aliases for `typescript` / `@typescript/native` - 17 package.json files: `@typescript/native` added beside each `typescript` dep so every package's `tsc` is the native binary - `apps/studio/tsconfig.json`: exclude `dist/` (gitignored build output) from typechecking **Fixed** (real type errors TS 6 under-reported): - `packages/ui-patterns` CodeBlock: `borderLeft: null` → `undefined` (`CSSProperties` doesn't accept null) - `apps/www` CodeBlock: removed a JSX `@ts-ignore` comment that tsgo doesn't honor and fixed what it masked (untyped `.js` theme objects, possibly-undefined highlighter children) ⚠️ **Merge timing:** the new packages are inside pnpm's 3-day `minimumReleaseAge` window until ~July 11. Installs from the committed lockfile are unaffected (resolution is skipped), but anything that forces a re-resolution before then will fail — hold off merging until the window passes. Note for editors: the compat package has no `lib/tsserver.js`, so VS Code's "Use Workspace Version" won't work — use the bundled TS or the TypeScript Native Preview extension. ## To test - `pnpm install && pnpm typecheck` — all 15 tasks green, and `./node_modules/.bin/tsc --version` prints 7.0.2 - `pnpm lint --filter=studio` — typescript-eslint still parses (resolves the 6.0 API) - `pnpm build --filter=design-system` (or any Next app) — Next's tsconfig validation and build typecheck still work - CodeBlock rendering on www (syntax highlighting, line highlights with/without border) — the two fixes are behavior-neutral but worth an eyeball <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Improvements / New Features** * Enhanced TypeScript tooling support across the workspace for smoother development builds and checks. * **Bug Fixes** * Code blocks render more reliably when content is empty or missing. * Highlighted code line styling applies more consistently. * **Maintenance** * Studio TypeScript builds now avoid including generated output (such as `dist`) during compilation. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Alaister Young <10985857+alaister@users.noreply.github.com> Co-authored-by: Ivan Vasilov <vasilov.ivan@gmail.com>
