* fix(journey): authorize reads of the journey share link GET /api/journeys/:id/share-link now requires journey access (canAccessJourney), matching the create/delete share-link routes and the get_journey_share_link MCP tool. Returns no link when the caller lacks access to the journey. * feat(costs): rework Budget into Costs — Splitwise-style, multi-currency, mobile Renames the Budget addon to "Costs" (UI only) and reworks it into a Tricount/ Splitwise-style cost tracker: multiple payers per expense, equal split across chosen members, settle-up with persisted history + undo, 12 fixed categories, per-expense currency with live FX conversion to a user-set display currency (Settings -> Display), and locale-correct money formatting. Adds a desktop and a dedicated mobile layout. A migration backfills existing budget items (single payer, split members, currency). Closes #551 (per-expense currency). Also switches the app font to self-hosted Poppins (Geist for secondary subtext), replacing the Google Fonts CDN dependency. * fix(costs): neutral dashboard dark palette + liquid glass, full page width, entry-count badge - Dark mode used a warm oklch palette that read brownish; switch to the neutral zinc tokens used by the dashboard (#121215 bg, #f4f4f5 ink) and add a subtle backdrop-blur glass on cards. - Costs now uses the full available page width on desktop instead of a 1280px cap. - Render the expense count next to the Expenses title as a badge. - Adapt budget/journey unit tests to the new payer-based settlement model and the Costs rename (category default 'other', Costs tab/CostsPanel). * fix(costs): drop the entry-count badge, always show row edit/delete actions Removes the count badge next to the Expenses title and makes the per-row edit/delete actions permanently visible (no longer hover-only) on desktop too. * feat(costs): currency-native money formatting, custom select/date, rename addon to Costs - Format every amount in its own currency convention (symbol position, grouping and decimal separators) regardless of app language, via a currency->locale map (EUR -> '12,00 €', USD -> '$12.00', JPY -> '¥12', ...). Previously Intl used the app locale, so EUR showed the symbol in front under an English UI. - Use TREK's CustomSelect (searchable, with symbols) and CustomDatePicker in the add/edit expense modal instead of the native <select>/<input type=date>. - Rename the 'Budget Planner' add-on to 'Costs' in the admin list (display only; id/tables/permissions/MCP stay 'budget') via seed + a migration for existing DBs. * feat(auth): configurable session duration via SESSION_DURATION Adds a SESSION_DURATION env var (ms-style strings: 1h, 7d, 30d, ...) controlling how long a session stays valid before re-login. It drives both the trek_session JWT exp claim and the cookie maxAge from one source, so they never drift. Invalid values warn at startup and fall back to the default (24h — unchanged). The MFA challenge token and MCP OAuth tokens keep their own TTL. Implements the request from discussion #946. Documented in the env-var wiki page, .env.example and docker-compose.yml.
@trek/shared
Single source of truth for TREK's API contracts, expressed as Zod schemas and consumed by both the server (request validation + inferred DTO types) and the client (typed requests/responses).
This package is part of the incremental NestJS + React 19 migration (see the "Brownfield Rewrite" board). It is intentionally dormant until modules start importing it — adding it changes nothing for users.
Rules
- One folder per domain:
src/<domain>/<domain>.schema.ts(+.spec.ts). - Domain-agnostic building blocks live in
src/common/. - A route is only considered migrated once its contract lives here.
- Schemas are the source of truth; server DTOs and client types are inferred from them
(
z.infer<typeof schema>), never hand-duplicated.
Consumption (dev)
Both apps resolve @trek/shared to this package's TypeScript source:
- Server (
tsx): viapathsinserver/tsconfig.json. - Client (
vite): viaresolve.aliasinclient/vite.config.ts(+pathsfor the type-checker).
Production packaging (Docker / workspace wiring) is introduced in card F2, when the server first depends on this package at runtime. Until then prod builds are untouched.
Not yet here
The canonical error envelope is finalised in card F5 (it must match TREK's current Express error responses byte-for-byte), so it is deliberately not invented in F1.
