First slice of the plugin system. Lays down the data model and a read-only admin surface; nothing executes yet. - Migration 155: plugins, plugin_meta_migrations, plugin_error_log and plugin_settings_fields tables. Plugin data will live in a per-plugin sqlite file under /plugins-data, never in these tables. - New Nest module server/src/nest/plugins with GET /api/admin/plugins (admin-gated, returns the installed list + the runtime-enabled flag). - TREK_PLUGINS_ENABLED kill switch (config.pluginsEnabled), off by default. - Admin → Plugins tab with a read-only panel: installed list, status badges, and a clear banner when the runtime is disabled by server config. - i18n keys for the tab and panel across all locales. Install, activation, the isolated runtime and the registry browser follow in later slices.
@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.
