chore: upgrade TypeScript to v7 by RounakKumarAgarwal · Pull Request #385 · AOSSIE-Org/Rein

RounakKumarAgarwal · 2026-08-16T07:55:31Z

Closes #381

What

Bumps typescript from ^5.7.2 to ^7.0.0.

Why

TS 7.0 (native Go compiler, "Project Corsa") went GA on July 8, 2026 with
typically 8-12x faster full builds. It's a faithful port, not a redesign —
type-checking semantics match 6.0.

Risk assessment for this repo

tsconfig.json uses moduleResolution: bundler + noEmit: true — Vite
does actual transpilation, tsc is type-check only.
Lint/format is Biome (Rust toolchain), not ESLint/@typescript-eslint, so
there's no typed-lint plugin depending on the TS compiler API.
TS 7.0 lacks a stable programmatic compiler API until 7.1 (~Oct 2026), but
nothing in this stack calls into that API directly, so it doesn't apply here.

Verification

npx tsc --noEmit — passes, zero errors
npm run build (Vite + Nitro) — passes
npm run check (Biome) — 56 pre-existing errors, confirmed unrelated by
comparing against TS 5.7.2 via git stash
npm test (Vitest) — no test files exist in the repo currently
(confirmed pre-existing, unrelated to this change)

Scoped narrowly to the TS version bump only — did not touch the pre-existing
Biome errors or missing tests, to keep this reviewable and separate from the
broader dependency cleanup in #362.

Summary by CodeRabbit

Chores
- Updated the TypeScript development tooling to a newer version.

- Bump typescript from ^5.7.2 to ^7.0.0 - TS 7.0 is a native Go port (Project Corsa), GA July 8 2026; type-checking semantics are unchanged from 6.0 - Verified: tsc --noEmit passes with zero errors, npm run build (Vite + Nitro) succeeds - Biome lint errors (56, pre-existing) and missing test files were confirmed unrelated to this change via git stash comparison against the prior TS version - No programmatic-compiler-API dependents in this stack (Vite uses bundler mode with noEmit:true; Biome is a separate Rust toolchain), so the 7.1 API gap does not apply here Closes AOSSIE-Org#381

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

package-lock.json is excluded by !**/package-lock.json

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

Hi, I received the Gitcord bot message asking me to join the AOSSIE Discord and verify my GitHub account. However, I'm currently unable to join the Discord because my account isn't recognized as a verified contributor yet. Could someone please help me get verified or let me know how I should proceed with the Gitcord linking process?

@RounakKumarAgarwal , could you share a screenshot of the error you get when you try to join https://discord.gg/hjUhu33uAn ?

@Zahnentferner

PinJinx · 2026-08-17T12:32:20Z

@RounakKumarAgarwal Just remove the node modules and package-lock then use npm install again to fix windows build error. ping me once done

RounakKumarAgarwal · 2026-08-17T12:35:00Z

@PinJinx yeah bro let me know what to do ?

PinJinx · 2026-08-17T12:36:30Z

Exactly what I have said in above message it will fix itself it's usually due to package-lock mismatch

RounakKumarAgarwal · 2026-08-17T12:48:39Z

I'm doing wait

@PinJinx

Delete node_modules and package-lock.json and reinstall fresh, per maintainer request (@PinJinx), to resolve the Windows CI failure where npm ci reported missing lru-cache/typescript entries. Also picks up transitive dependency drift in the Oxc/Rolldown toolchain used by Vite (unrelated to TypeScript itself). Verified tsc --noEmit and npm run build both still pass cleanly.

RounakKumarAgarwal · 2026-08-17T12:58:09Z

Done @PinJinx

PinJinx · 2026-08-18T15:22:14Z

Merged, Thanks for the contribution!
