feat(deps): update typescript to v6 and peer ranges by Timeless0911 · Pull Request #1553 · web-infra-dev/rslib

Timeless0911 · 2026-03-24T12:02:54Z

Summary

Upgrade the workspace TypeScript version to v6 and align the repo with TypeScript 6 behavior across packages, templates, examples, and integration fixtures.

This removes redundant tsconfig entries where TS 6 now provides the intended default, keeps explicit settings where a floating default would make output less stable, and updates declaration fixtures to match TS 6 ESM output.

TypeScript 6 Default Changes

Change	TypeScript 6 default	Repo handling
`types`	`[]`	Added explicit `"types": ["node"]` in Node-side tsconfig files so built-in modules like `node:fs` continue to resolve during type-checking.
`strict`	`true`	Removed redundant `"strict": true` from templates/examples that already expect strict mode, and kept `"strictNullChecks": true` explicit in the shared internal base tsconfig so the current `rslint` typed rules can resolve the setting reliably.
`module`	`esnext`	Removed redundant `"module": "ESNext"` where ESM was already the intended behavior.
`target`	current-year ES target (`es2025` at the time of TS 6.0)	Kept explicit targets where output/runtime stability matters, instead of relying on a floating default.
`noUncheckedSideEffectImports`	`true`	No repo-wide override was added; current configs and fixtures are compatible with the stricter default.
`libReplacement`	`false`	No repo-wide override was added; the repo does not rely on the previous default behavior.

Peer Changes

Widen the TypeScript peer range in @rslib/core and rsbuild-plugin-dts from ^5 to ^5 || ^6 so package consumers can adopt TS 6 without a peer warning from Rslib itself.

Pull request overview

Upgrades the workspace to TypeScript 6 and adjusts tsconfig/templates/tests/fixtures to match TS 6 defaults and declaration output behavior across the monorepo.

Changes:

Bump TypeScript to ^6.0.2 across root, packages, templates, examples, docs, and integration fixtures.
Update many tsconfig.json files to reflect TS 6 defaults (notably adding types: ["node"] where needed and removing redundant options).
Refresh redirect/dts integration fixtures and snapshots to match TS 6 declaration emission.

scripts/tsconfig/base.json:12

Re-adding/removing strict here changes the default type-checking mode for every project extending @rslib/tsconfig/base. In the current base config there’s no other option enabling strict mode, so dropping strict: true disables noImplicitAny, strictNullChecks, etc. If the repo still expects strict type-checking, put strict: true back in the base config (or explicitly enable the specific strict flags you want) so templates/examples don’t silently lose checks.
