Phase 0 diagnostic — what's actually blocking the TypeScript 6.0 bump

I dug into this to figure out whether the 9,475 errors reported by CI represent the real scope of the migration or not. Good news: the real scope is dramatically smaller than it looks.

Setup

• Bumped to TS 6.0.3, clean npm ci
• rm -rf packages/*/lib plugins/*/lib + deleted *.tsbuildinfo
• Ran root tsc --build

Error count by compiler-option regime

Config	Total errors
Clean build, noEmitOnError: true (repo default)	9,475
Same build, noEmitOnError: false	63

That ~150× ratio is the whole story. Here's what's happening:

1. The repo uses project references (composite: true).
2. Upstream packages like superset-core have a handful of real TS 6.0 errors (class-property init + CSS side-effect import declarations + the baseUrl deprecation — 10 errors total).
3. With noEmitOnError: true, those 10 errors block emission of packages/superset-core/lib/**/*.d.ts.
4. Every downstream package and the main src/ tree then fails with TS6305 for each import of @apache-superset/core / @superset-ui/core, and because the types don't resolve, every destructured prop falls back to any — producing ~2,500 spurious TS7006/TS7031 errors plus ~500 TS2339s.

Fix the upstream 10, and the cascade vanishes.

The real error set (63 errors, 36 files)

With emission forced (noEmitOnError: false), the actual TS 6.0 migration surface is:

Errors	Code	Fix
24	TS5101	Add \"ignoreDeprecations\": \"6.0\" to root tsconfig.json and each package/plugin tsconfig that sets baseUrl
20	TS4023	Export the referenced type from its source module (affects src/dashboard/components/gridComponents/index.ts, src/explore/components/controls/index.ts, withAsyncVerification.tsx, TabbedSqlEditors/index.tsx)
8	TS4082	Name the default-export type explicitly (Dashboard.ts, DashboardGrid.tsx, FilterScope.tsx, reducerIndex.ts, TabbedSqlEditors)
5	TS2883	Add an explicit return-type annotation for StyledJsonEditor (DatabaseModal/styles.ts) and StyledCronPicker (ReportModal/styles.tsx)
4	TS4058	Related to the TS4082 fixes in TabbedSqlEditors
2	TS9006	Add explicit annotations in spec/fixtures/mockDashboardFilters.js, mockStore.js

Plus the 10 upstream errors (TS2564 in Theme.tsx, TS2882 in GlobalStyles.tsx, TS5101 in each package tsconfig) that are already counted above or fall under the same categories.

That totals roughly 35–40 files of mechanical edits, no design decisions, no large-scale rewrites.

Revised migration plan

Given the real scope, this is much closer to a single PR than the ~15-PR estimate I initially sketched. Reasonable staging:

1. Phase A — tsconfig hygiene + CSS module declarations (new PR, can land today on TS 5.4)

   • ignoreDeprecations: \"6.0\" in ~24 tsconfigs (caveat: may require TS 5.5+ — checking)
   • Add *.d.ts declaring @fontsource/* CSS side-effect modules
   • Add definite-assignment (!) to Theme.tsx class properties

2. Phase B — declaration-emit annotations (new PR on TS 5.4)

   • Fix the TS4023/TS4058/TS4082/TS9006/TS2883 cases by exporting/annotating types in the ~10 affected files.
   • These are all forward-compatible with TS 5.4.

3. Phase C — the actual bump (rebase this PR)

   • Once A and B land, the TS 5.4.5 → 6.0.3 diff is just package.json/package-lock.json.

The flaky FiltersConfigModal keyboard-reorder 30s timeout from the original triage is unrelated to TS and should be handled separately.

Next step

I'll open the Phase A PR shortly. Holding this PR open as tracker for the full migration.

[rusackas]

Phase A is up for review: #39530

Following up on the Phase 0 diagnostic above — I split out the forward-compatible subset of fixes into #39530 so they can land on TS 5.4 today without waiting for the full bump.

Phase A contents (20 files):

• TS2883 — as typeof Component casts on styled(JsonEditor) / styled(CronPicker) (named-reference emit)
• TS2882 — declare module '@fontsource/*' for side-effect CSS imports
• TS2564 — definite-assignment on Theme.tsx class fields
• TS4023/TS4082 — export on 15 interfaces/types reachable from exported symbols

Verified clean on TS 5.4.5 (tsc --build + full pre-commit suite). All 65 CI checks green.

Remaining for this PR (Phase C): once Phase A lands, the TS 5.4 → 6.0 bump itself becomes a smaller diff focused on tsconfig.json (baseUrl removal, ignoreDeprecations: "6.0") and any straggler cases. I'd suggest closing this Dependabot PR once #39530 merges so Dependabot re-opens a fresh bump against the already-prepared tree.
