Installs @total-typescript/ts-reset 0.6.1 as a dev-dependency in
apps/portal/ and apps/app/. Patches TypeScript's loosest default
types: Array.filter(Boolean) returns non-nullable, JSON.parse
returns unknown, fetch().json() returns unknown, Map.get() strict,
etc.
Configuration: src/reset.d.ts in each SPA imports the reset. Both
tsconfig.json files already include ./src/**/* so the .d.ts is
picked up automatically — no tsconfig edits needed.
Issues surfaced during install:
- apps/app — 0 pre-install tsc errors in own code; install
surfaced 2 errors in src/stores/useImpersonationStore.ts
(both from JSON.parse on sessionStorage content returning
unknown instead of any). Fixed inline at lines 19 + 123 via
`as ImpersonationState` casts that make the existing
trust-in-sessionStorage explicit. Backlog entry
TECH-TS-IMPERSONATION tracks proper runtime shape validation.
- apps/portal — 22 pre-existing tsc errors in own code (mostly
tiptap editor components — tracked as TECH-TS-PORTAL-TSC,
unrelated to ts-reset). Zero new errors in portal's own code.
4 additional errors surfaced in tiptap's uncompiled node_modules
.ts sources (third-party); left as-is.
Neither SPA achieves `tsc --noEmit` clean today — pre-existing
state unrelated to this work package. Build + vitest are the
actual working gates and both remain green:
- apps/portal: vitest 113/113 passing; production build succeeds
- apps/app: (no vitest setup — tracked as TECH-APP-VITEST);
production build succeeds
Documentation: /dev-docs/FRONTEND-TOOLING.md added; CLAUDE.md
quality-gates updated.
Backlog: TECH-TS-IMPERSONATION (runtime validation of stored
impersonation state), TECH-TS-PORTAL-TSC (pre-existing portal tsc
errors), TECH-APP-VITEST (Vitest coverage for apps/app).
No production behavior change.

# Frontend tooling
|
|
|
|
Type-safety and quality tooling for the Vue 3 + TypeScript SPAs.
|
|
|
|
## ts-reset
|
|
|
|
Installed in both `apps/portal/` and `apps/app/` as a dev-dependency.
|
|
Imported via `src/reset.d.ts`:
|
|
|
|
```typescript
|
|
import '@total-typescript/ts-reset'
|
|
```
|
|
|
|
Both SPAs' `tsconfig.json` include `./src/**/*`, so the `.d.ts` is
|
|
picked up automatically — no explicit `include` edit needed.
|
|
|
|
### What it changes
|
|
|
|
ts-reset patches TypeScript's loosest default types:
|
|
|
|
- `Array.filter(Boolean)` returns non-nullable `Array<T>` instead
|
|
of `Array<T | null | undefined | false | 0 | "">`
|
|
- `JSON.parse` returns `unknown` instead of `any`
|
|
- `fetch().then(r => r.json())` returns `unknown` instead of `any`
|
|
- `Array.includes()` accepts narrower types
|
|
- `Map.get()` returns `T | undefined` more strictly
|
|
- See <https://github.com/total-typescript/ts-reset> for the full list
|
|
|
|
### Why this matters
|
|
|
|
The default TypeScript types for these built-ins lose information
|
|
that real code relies on. ts-reset fixes the types to match runtime
|
|
behavior, surfacing bugs that were previously hidden.
|
|
|
|
### Adoption state
|
|
|
|
**apps/app** — 0 pre-install tsc errors in own code; install
|
|
surfaced 2 errors in `src/stores/useImpersonationStore.ts` (both
|
|
from `JSON.parse` on sessionStorage content). Both fixed inline via
|
|
`as ImpersonationState` assertions that make the existing trust-in-
|
|
sessionStorage explicit. A backlog entry (TECH-TS-IMPERSONATION)
|
|
tracks proper runtime validation of the stored shape.
|
|
|
|
**apps/portal** — 22 pre-existing tsc errors in own code (mostly
|
|
tiptap editor components — unrelated to ts-reset). ts-reset added
|
|
0 new errors in portal's own code. 4 additional errors surfaced in
|
|
tiptap's third-party `.ts` sources under `node_modules` (tiptap
|
|
ships uncompiled TypeScript and some of its internal `JSON.parse`
|
|
call sites fall under ts-reset's tightening). Not our code; left
|
|
as-is.
|
|
|
|
Neither SPA achieves `tsc --noEmit` clean today — that's a pre-
|
|
existing state unrelated to this work package. Build + vitest are
|
|
the actual CI-relevant gates and both remain green.
|
|
|
|
### Bypassing
|
|
|
|
`@ts-expect-error` with comment justification at the call site —
|
|
never blanket-disable ts-reset. If a specific reset is genuinely
|
|
wrong for the project, document it; the upstream issue is the
|
|
backstop.
|
|
|
|
## Vitest
|
|
|
|
Runs against `apps/portal/`. `apps/app/` has no test suite yet —
|
|
build + typecheck are its only automated gates. Bringing Vitest
|
|
coverage to `apps/app` is a separate backlog item.
