Session Handoff: Build Fixes & Dev Environment

Date: 2026-03-15 Session Duration: ~2 hours Session Focus: Resolve all TypeScript/ESLint build errors from dependency updates; fix dev server startup Context Usage at Handoff: Medium

What Was Accomplished

1. Fixed 30 TypeScript errors (14 files) → build now passes with 0 errors
2. Fixed 12 ESLint problems (6 errors, 6 warnings) → 0 remaining
3. Fixed quasar dev startup error (FlatESLint is not a constructor) → downgraded ESLint v10→v9
4. Fixed missing Appwrite env vars in .env.local → app connects to backend on dev

Exact State of Work in Progress

• Build: CLEAN — yarn quasar build exits 0, no TS or ESLint errors
• Dev server: FUNCTIONAL — quasar dev starts without errors; ESLint inline checking via vite-plugin-checker is restored
• Runtime: UNTESTED this session — app has not been manually tested against the dev Appwrite backend

Decisions Made This Session

• as unknown as Type for all Appwrite store casts — CONFIRMED: Appwrite v23 made DefaultDocument strict; it no longer overlaps domain types, so the double-cast is required. Applied to: boat.ts, interval.ts, intervalTemplate.ts, reservation.ts, task.ts
• ESLint downgraded v10.0.3 → v9.39.4 — CONFIRMED: vite-plugin-checker v0.12.0 calls FlatESLint which was merged back into ESLint in v10; v9 preserves the API. Also downgraded @eslint/js (v10→v9) and eslint-plugin-vue (v10→v9)
• getWeekdaySkips removed — CONFIRMED: removed from @quasar/quasar-ui-qcalendar API; createDayList now takes weekdays array directly as 4th param (previously took weekdaySkips computed value)
• subtasks removed from TaskCardComponent template — ASSUMED SAFE: Task type has no subtasks field; template refs were dead code. See open question.
• no-debugger: 'off' — CONFIRMED: hardcoded because process is not available in ESLint globals when linting .js files (config file context)
• .env.local variable names corrected — CONFIRMED: file had VITE_APPWRITE_ENDPOINT / VITE_APPWRITE_PROJECT; appwrite.ts reads VITE_APPWRITE_API_ENDPOINT / VITE_APPWRITE_API_PROJECT

Key Numbers Generated or Discovered This Session

• TypeScript errors at session start: 30 (across 14 files)
• ESLint problems at session start: 12 (6 errors, 6 warnings)
• TypeScript errors at session end: 0
• ESLint problems at session end: 0
• ESLint: v10.0.3 → v9.39.4
• @eslint/js: v10 → v9
• eslint-plugin-vue: v10 → v9
• register-service-worker: newly added (was missing from package.json)

Conditional Logic Established

• IF Appwrite SDK returns DefaultDocument THEN cast via as unknown as DomainType BECAUSE v23 DefaultDocument is strict and no longer assignable to domain types that extend Partial<Models.Document>
• IF vite-plugin-checker is v0.12.x THEN ESLint must be v9.x BECAUSE v0.12.x uses FlatESLint constructor removed in ESLint v10
• IF createDayList is called from qcalendar THEN pass weekdays array as 4th arg directly BECAUSE getWeekdaySkips was removed from the qcalendar public API
• IF .env.local is updated THEN variable names must match import.meta.env.VITE_APPWRITE_API_ENDPOINT / VITE_APPWRITE_API_PROJECT as read in src/boot/appwrite.ts

What the NEXT Session Should Do

1. First: Run quasar dev and manually test the login flow against the dev Appwrite backend to validate v23 API calls work at runtime
2. Validate: Boat listing, reservation creation/cancellation, interval loading — confirm no runtime errors from the v23 positional-param deprecations
3. Commit: Stage all modified files and commit as "fix: Resolve build errors from dependency updates" (single clean commit covering all TS/ESLint/qcalendar/env fixes)
4. Optional: Migrate Appwrite calls from deprecated positional-param style to object-param style (affects all stores — low priority, they still work)
5. Optional: Add subtasks?: Task[] to Task interface in src/stores/task.ts if that feature is planned

Open Questions Requiring User Input

• task.subtasks removed from TaskCardComponent template — should subtasks?: Task[] be added to the Task interface for future use, or is subtask support not planned?
• Appwrite v23 deprecated positional-param overloads (hints in every store call). Migrate now or leave for later?

Assumptions That Need Validation

• ASSUMED: Appwrite v23 positional-param API calls behave identically at runtime to v14 — validate by doing a full login + reservation flow against the dev backend
• ASSUMED: subtasks in TaskCardComponent was dead/future code — no user confirmed this

What NOT to Re-Read

• docs/archive/handoffs/handoff-2026-03-15-dependency-updates.md — archived; superseded by this file
• docs/archive/handoffs/handoff-2026-03-15-auth-magic-link.md — archived; auth work complete

Files to Load Next Session

• src/stores/task.ts — if adding subtasks to Task interface
• src/boot/appwrite.ts — if migrating to Appwrite v23 object-param style
• Any store file (boat.ts, interval.ts, reservation.ts, etc.) — if migrating Appwrite calls
