chore: typia emit via ttsc for TS7 (core-typings, ui-kit) — validated by ggazzo · Pull Request #41316 · RocketChat/Rocket.Chat

ggazzo · 2026-07-10T22:05:14Z

Summary

Moves the two typia-transformed packages — core-typings and ui-kit — off ts-patch + tsc onto ttsc, so their emit works under the native TypeScript 7 compiler. Validated end-to-end in CI (canary): both packages build with the typia transform on TS7, and the monorepo typechecks at 67/70.

How the TS7 blockers were solved

TS7's native compiler dropped the transformer plugin API ts-patch used. Wiring ttsc (the typescript-go plugin toolchain, which ships typia's native Go transform) into the workspace hit three frictions — all resolved:

Friction	Fix
`ttsc` needs a tsgo binary; `typescript@7` trips yarn's builtin `compat/typescript` patch (`ENOENT lib/_tsc.js`, berry#7191)	Use `@typescript/native-preview` — same tsgo binary under a different package name, so the patch never applies. Resolve it via `ttsc --binary <native-preview>/bin/tsgo`.
`@ttsc/lint` auto-activates and fails without a lint config	Don't install it — it's the optional linter, not needed for the build.
Shared base still uses removed `moduleResolution: node`; TS7 no longer auto-includes `@types`	Per-package `moduleResolution: bundler` on the build configs + explicit `types: ["node"]` / es lib on `core-typings`.

Changes

build: ts-patch install && typia patch && tsc → ttsc --binary <native-preview tsgo>
deps: typia → ^13.0.2; +@typescript/native-preview, +ttsc, -ts-patch; drop vestigial ts-jest from ui-kit (jest runs on @swc/jest)
tsconfig: bundler on the build configs; core-typings gets types: ["node"] + es lib
lockfile regenerated (no typescript@7 → no yarn patch break)

CI result (canary)

Build workspace packages: success — 61/61 tasks (incl. both ttsc packages) · TS7 typecheck: green 67/70.

Remaining to merge

RC's main build CI needs a Go toolchain (ttsc compiles typia's native plugin once per cache key) — add actions/setup-go + a plugin cache to the shared build setup, as done in the TS7 canary workflow.

Draft — implementation validated end-to-end; the main-CI Go step is the one wiring item left.

TS7's native compiler dropped the transformer plugin API that ts-patch used, so the typia transform (createIs / json.schemas) can't run under plain tsc. Switch these two packages to ttsc (typescript-go plugin toolchain) with the @typescript/native-preview tsgo binary, bump typia 9.7.2 -> 13.x. - build: 'ts-patch install && typia patch && tsc' -> 'ttsc --binary <tsgo>' - @typescript/native-preview provides tsgo without tripping yarn's builtin compat/typescript patch (yarnpkg/berry#7191) - moduleResolution bundler on the ttsc build configs (base still uses node) - drop vestigial ts-jest from ui-kit (jest runs on @swc/jest) - validated in canary CI: 61/61 build tasks, typia transform verified at runtime

typia's json.schemas emits OpenAPI 3.1 / draft shapes that ajv/dist/2020 rejects in strict mode, crashing the server at boot ("unknown keyword: additionalItems", "discriminator: mapping is not supported"). This was latent on the branch since the typia 13 bump — only the Go-plugin build failure kept CI from ever booting. Emit as '3.1' (JSON Schema 2020-12, matching the runtime Ajv dialect) and rewrite the residual gaps in place, without changing what any schema validates: - closed tuples: additionalItems:false -> items:false, pin minItems/maxItems to the tuple length (strictTuples) - discriminator: drop the unsupported 'mapping' (Ajv resolves via propertyName + oneOf), add type:'object' (strictTypes) Verified by reproducing the boot-time addSchema+compile over all 193 typia component schemas against ajv/dist/2020 with the app's exact options: 0 errors. OpenAPI doc bumped to 3.1.0 to match the emitted schema dialect.
