2 
3Concise but detailed reference for contributors working in the `groupultra/telegram-search` monorepo. Improve code when you touch it; avoid one-off patterns.

5## Tech Stack (by surface)
6 
7- **Server (`apps/server`)**: Node.js, TypeScript, Drizzle ORM, Postgres/pgvector, WebSocket + REST, dotenvx.
8- **Web (`apps/web`)**: Vue 3 + Vite, Pinia.
9- **Core/shared (`packages/*`)**: common types, client SDK, schema, core services, bot.
10- **Tooling**: pnpm workspaces, Vitest, ESLint, TypeScript 5.9, tsdown, Drizzle Kit.
11 
12## Structure & Responsibilities
13 
14- **Apps**
15  - `apps/server`: backend service (runtime entry in `apps/server/src/`).
16  - `apps/web`: web UI (source in `apps/web/src/`).
17- **Packages**
18  - `packages/`: shared libraries and domain logic used by apps.
19- **Root tooling**
20  - Linting: `eslint.config.ts`.
21  - DB tooling: `drizzle/`, `drizzle.config.ts`.
22  - Workspace: `pnpm-workspace.yaml`.
23 
24## Key Path Index (what lives where)
25 
26- `apps/server/src`: API, WebSocket, and session services.
27- `apps/web/src`: Vue UI and client-side logic.
28- `packages/core`: core domain/services.
29- `packages/schema`: shared types + DB schema.
30- `packages/client`: client SDKs for integration.
31- `docker/`: compose files + init scripts for local/dev.
32- `.env.example`: baseline env config.
33 
34## Commands (pnpm with filters)
35 
36> Use pnpm workspace filters to scope tasks, e.g. `pnpm -F @tg-search/server dev`.
37 
38- **Dev (web only)**: `pnpm run web:dev`
39- **Dev (server only)**: `pnpm run server:dev`
40- **Dev (web + server)**: `pnpm run start`
41- **Build web**: `pnpm run build`
42- **Build server**: `pnpm run server:build`
43- **Run tests**: `pnpm run test:run`
44- **Coverage**: `pnpm run test:coverage`
45- **Lint**: `pnpm run lint` / `pnpm run lint:fix`
46- **Typecheck**: `pnpm run typecheck`
47- **DB generate**: `pnpm run db:generate`
48 
49## Dependency Management Rule
50 
51- Do not edit `package.json` directly to add/remove deps. Use `pnpm install` so lockfile and manifest stay in sync.
52- For workspace deps: `pnpm install -F <target> <dependency>` (add `-D` for dev deps).
53- Tooling like `typescript`, `vite`, `vitest`, `tsdown`, `@types/node` belongs at the workspace root (`-w`).
54 
55## Styling & Conventions
56 
57- Favor clear module boundaries; shared logic goes in `packages/`.
58- Keep runtime entrypoints lean; move heavy logic into services/modules.
59- Prefer functional patterns for testability; use DI where helpful. Avoid classes unless required by APIs.
60- Use Valibot for schema validation; keep schemas close to their consumers.
61- Use Eventa (`@moeru/eventa`) for structured IPC/RPC contracts where needed.
62- File names: `kebab-case`.
63- Do not add backward-compatibility guards. If extended support is required, write refactor docs and complete the change in a separate, well-scoped effort.
64- If the refactor scope is small, do a progressive refactor step by step.
65- When modifying code, look for small, safe refactors to reduce duplication or improve clarity.
66- If you need a workaround, add a `// NOTICE:` comment explaining why, the root cause, and any relevant context.
67 
68## Testing Practices
69 
70- Use Vitest for unit/integration tests.
71- Mock external services and Postgres where practical; keep tests deterministic.
72- When fixing a bug, add a Vitest test that documents the previous failure mode and include a short `//` comment about the cause.
73- For DB interactions, prefer migration-driven integration tests with env guards.
74 
75## TypeScript / Tooling
76 
77- Stay strict with types; avoid `any` unless absolutely necessary.
78- Prefer small, composable modules; keep exports minimal and intentional.
79 
80## Refactoring & Comments
81 
82- Prefer progressive, incremental refactors that keep behavior stable.
83- Keep existing comments with the code when moving/refactoring. If a comment becomes obsolete, replace it with a brief note about why it was removed.
84- Use markers consistently: `// TODO:`, `// REVIEW:`, `// NOTICE:`.
85- Add concise comments for complex logic, algorithms, OS-interaction, and shared utilities. Avoid obvious comments.
86 
87## PR / Workflow Tips
88 
89- Keep changes scoped; use workspace filters for commands.
90- Summarize changes, how tested (commands), and follow-ups.
91- Improve legacy when you touch it; avoid one-off patterns.
92- Maintain structured `README.md` documentation for each `packages/` and `apps/` entry.
93- Always run `pnpm run typecheck` and `pnpm run lint:fix` after finishing a task.
94- Use Conventional Commits (e.g., `feat(server): add session refresh`).
95 
96## Docker + SQL Conventions
97 
98- Use `docker-compose.yml` as the compose filename.
99- Do not write SQL migration files manually. Always use `drizzle-kit generate` to create migrations, which will be placed in `**/sql/` with descriptive, kebab-case names.
100- Avoid Postgres enums to keep migrations and imports flexible.
