chore: upgrade typescript to 6.0.3 by eduard-jacko · Pull Request #4737 · module-federation/core

eduard-jacko · 2026-05-18T16:30:40Z

Summary

Upgrades TypeScript from 5.9.3 to 6.0.3 (latest stable) across the entire monorepo.

Updates root devDependency and adds pnpm override for consistent resolution
Adds || ^6.0.0 to peer dependencies (keeps backwards compat with TS 4.9+ and 5.x)
Migrates moduleResolution: "node" → "node10" in all tsconfigs (same behavior, silences TS 6 deprecation)
Adds ignoreDeprecations: "6.0" for baseUrl and moduleResolution deprecations
Adds explicit strict: false to base tsconfig (preserves TS 5.x default since TS 6 defaults strict to true)
Fixes 2 source files in chrome-devtools affected by stricter type checking

Key decisions

Backwards compatible: peer deps remain "^4.9.0 || ^5.0.0 || ^6.0.0" so existing TS 5 users are unaffected
moduleResolution: "node10": semantically identical to "node", just the new non-deprecated name
ignoreDeprecations: "6.0": suppresses warnings for baseUrl and moduleResolution until a future migration to "bundler" resolution

Verification

✅ pnpm run build:packages — 41/41 pass
✅ pnpm run test:packages — 76/77 pass (1 unrelated Playwright/Chromium env issue)
✅ pnpm run lint — 35/35 pass
✅ Multi-version type compatibility tested: built .d.ts files validated against TS 5.4.5, 5.9.3, and 6.0.3

Test plan

CI build passes
CI tests pass
Verify no type regressions in consuming projects

Bundle sizes are generated with rslib (Rspack). Package-root metrics preserve the historical report. Tracked subpath exports such as ./bundler are measured separately so ENV_TARGET-driven tree-shaking is visible. Bare imports are externalized to keep package-level sizes consistent, and assets are emitted as resources.

The PR has one comment that needs to be addressed, and it also needs to fix the CI issue.

2heal1 · 2026-05-28T03:29:07Z

Could you please rebase this branch on the latest main and resolve the current conflicts? We can continue review once the branch is up to date.

crutch12 · 2026-06-21T10:51:16Z

Hope for you, guys 👀

eduard-jacko · 2026-06-23T08:44:47Z

@2heal1 please let me know if there is anything else need to be done.

joshuaellis · 2026-06-24T17:40:12Z

This has hit us over at sanity.

CC @gioboa anything you can do to nudge this along?

@ts-expect-error

- Update root devDependency from 5.9.3 to 6.0.3 - Add pnpm override to ensure consistent TS version across all packages - Update peer dependencies to include ^6.0.0 (maintaining ^4.9.0 || ^5.0.0 compat) - Update sub-package devDependencies to ^6.0.3 - Migrate moduleResolution from "node" to "node10" across all tsconfigs - Add ignoreDeprecations: "6.0" for baseUrl and moduleResolution deprecations - Add strict: false to base tsconfig (preserves TS 5.x default behavior) - Fix chrome-devtools type assertion and unused @ts-expect-error - Update native-federation-typescript test expectations for ignoreDeprecations

Remove the heavy-handed `"typescript": "$typescript"` pnpm override and instead add explicit `"typescript": "6.0.3"` devDependencies to the 15 packages that resolve to TS 5.x through transitive peer deps. Also fix dts-plugin test assertions for TS 6 (moduleResolution and ignoreDeprecations values).

@ts-ignore

- bridge-shared: import CSSProperties as type - bridge-shared: types path -> ./dist/src/index.d.ts - bridge-react-webpack-plugin: types: ["node"] for node:* imports - vue3-bridge: @ts-ignore __APP_VERSION__ Vue 3 typing - chrome-devtools: cast __FEDERATION__ assignment (TS2322) - dts-plugin test: node10 + ignoreDeprecations fixture

ogonkov · 2026-07-07T06:43:19Z

  "main": "./dist/index.umd.js",
  "module": "./dist/index.es.js",
-  "types": "./dist/index.d.ts",
+  "types": "./dist/src/index.d.ts",


That doesn't look right tbh

ogonkov · 2026-07-07T06:46:37Z

  hashRoute?: boolean;
 }) {
  return defineAsyncComponent({
+    // @ts-ignore


This ts-ignore will remain in codebase? Or this should be addressed in future?

ogonkov · 2026-07-07T06:58:49Z

  "devDependencies": {
-    "@types/node": "^20.19.5"
+    "@types/node": "^20.19.5",
+    "typescript": "6.0.3"


Why version is explicitly locked?
