build: upgrade to TypeScript 7 by zhyd1997 · Pull Request #827 · softmaple/softmaple

zhyd1997 · 2026-07-29T21:44:32Z

Summary

use the native TypeScript 7.0.2 compiler for repository typechecking
retain the official TypeScript 6 compatibility package for tools that still import the JavaScript API, including ESLint, Storybook, Vite declaration tooling, and tsup
enable Next.js's TypeScript CLI integration so the web production build runs TS7 directly
remove TS7-incompatible baseUrl settings and add explicit Node ambient types where the new defaults require them
scope a workaround for tsup#1388 to the eg-walker declaration build
update Renovate grouping and the pnpm lockfile

This follows the TypeScript 7 migration guidance while the stable programmatic API is still transitioning.

Closes #825.

Performance

Measured on an Apple M1 MacBook Pro with 16 GB RAM and Node 24.12.0. The web comparison used seven warmed, alternating direct runs of:

tsc -p apps/web/tsconfig.json --noEmit --pretty false

Compiler	Median wall time	Peak RSS	Relative
TypeScript 5.9.3	3.33 s	504,437 KB	1.00x
TypeScript 7.0.2	0.53 s	322,384 KB	6.28x faster

--extendedDiagnostics compiler time improved from 2.57 s to 0.45 s (5.71x), while peak memory fell by 36.1%.

Across five representative workspace configurations, the co-installed TS6 API bridge took 11.54 s in aggregate versus 2.23 s for native TS7, a 5.17x speedup.

Validation

pnpm install --offline --frozen-lockfile
pnpm build — 7/7 production build tasks passed
native TS7 typechecks for web, playground, awareness, bench, config, editor, eg-walker, md2latex, and UI
Vitest/Node test suites for web, playground, awareness, editor, bench, md2latex, and ESLint config
pnpm --filter @softmaple/web lint
pnpm --filter @softmaple/eg-walker lint
pre-commit Biome and lint-staged hooks
git diff --check

Existing unrelated failures

Repository-wide pnpm lint still reports existing Biome errors in unchanged playground source files; targeted checks for this change pass.
The existing eg-walker deferred-text-materialization property test reproducibly exposes a runtime algorithm defect after hundreds of generated traces. No eg-walker runtime or test source changed here; the other 710 tests pass, including the convergence property when rerun in isolation.

Screenshots are not applicable because this change has no UI impact.

Summary by CodeRabbit

Chores
- Updated the project’s TypeScript tooling to support newer TypeScript releases.
- Enabled the web app’s TypeScript command-line integration.
- Removed obsolete module-resolution settings while preserving existing path aliases.

📝 Walkthrough

Walkthrough

The repository updates its TypeScript development toolchain to TypeScript 6 and native TypeScript 7, removes baseUrl compiler settings, adds explicit Node typings where needed, and adjusts Next.js and tsup integrations.

Changes

TypeScript toolchain upgrade

Layer / File(s)	Summary
TypeScript dependency rollout `.github/renovate.json`, `package.json`, `apps//package.json`, `packages//package.json`	TypeScript 6 aliases and native TypeScript 7 dependencies are added across the repository, and Renovate grouping includes `@typescript/typescript6`.
Compiler configuration updates `apps//tsconfig.json`, `packages//tsconfig*.json`	`baseUrl` is removed while existing path mappings remain; benchmark and eg-walker configurations explicitly include Node typings.
Build and DTS integrations `apps/web/next.config.mjs`, `packages/eg-walker/tsup.config.ts`	Next.js enables `useTypeScriptCli`, and tsup declaration generation receives an `ignoreDeprecations` compiler option.
