# CLAUDE.md
|
||||
|
||||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Project Overview
|
||||
|
||||
Memos is a lightweight, self-hosted knowledge management and note-taking platform. The architecture pairs a Go backend with a React+Vite frontend, using gRPC for internal communication and providing REST API access via gRPC-Gateway.
|
||||
|
||||
## Development Commands
|
||||
|
||||
### Backend (Go)
|
||||
|
||||
**Start Development Server:**
|
||||
```bash
|
||||
go run ./cmd/memos --mode dev --port 8081
|
||||
```
|
||||
|
||||
**Build Binary:**
|
||||
```bash
|
||||
go build ./cmd/memos
|
||||
```
|
||||
|
||||
**Run Tests:**
|
||||
```bash
|
||||
go test ./... # All tests
|
||||
go test ./store/... # Store layer tests only
|
||||
go test ./server/router/api/v1/test/... # API tests
|
||||
```
|
||||
|
||||
**Lint:**
|
||||
```bash
|
||||
golangci-lint run # Full lint check (uses .golangci.yaml)
|
||||
```
|
||||
|
||||
**Generate Protocol Buffers:**
|
||||
```bash
|
||||
cd proto
|
||||
buf generate # Generate Go/TypeScript from .proto files
|
||||
buf format -w # Format proto files
|
||||
```
|
||||
|
||||
### Frontend (React + Vite)
|
||||
|
||||
**Install Dependencies:**
|
||||
```bash
|
||||
cd web
|
||||
pnpm install
|
||||
```
|
||||
|
||||
**Development Server:**
|
||||
```bash
|
||||
cd web
|
||||
pnpm dev # Hot-reload dev server (typically :5173)
|
||||
```
|
||||
|
||||
**Build:**
|
||||
```bash
|
||||
cd web
|
||||
pnpm build # Build to web/dist/
|
||||
pnpm release # Build and copy to server/router/frontend/dist/
|
||||
```
|
||||
|
||||
**Lint:**
|
||||
```bash
|
||||
cd web
|
||||
pnpm lint # TypeScript check + ESLint
|
||||
```
|
||||
|
||||
### CLI Flags and Environment Variables
|
||||
|
||||
The backend accepts the following configuration via flags or `MEMOS_*` environment variables:
|
||||
|
||||
- `--mode` / `MEMOS_MODE` - Runtime mode: `dev`, `prod`, `demo` (default: `prod`)
|
||||
- `--addr` / `MEMOS_ADDR` - Bind address (default: `0.0.0.0`)
|
||||
- `--port` / `MEMOS_PORT` - HTTP/gRPC port (default: `5230`)
|
||||
- `--unix-sock` / `MEMOS_UNIX_SOCK` - Unix socket path (optional)
|
||||
- `--data` / `MEMOS_DATA` - Data directory for SQLite (default: `~/.memos`)
|
||||
- `--driver` / `MEMOS_DRIVER` - Database driver: `sqlite`, `mysql`, `postgres` (default: `sqlite`)
|
||||
- `--dsn` / `MEMOS_DSN` - Database connection string (for MySQL/PostgreSQL)
|
||||
- `--instance-url` / `MEMOS_INSTANCE_URL` - Public instance URL for webhooks/OAuth
|
||||
|
||||

```
|
||||
|
||||
### API Architecture
|
||||
|
||||
**Dual Protocol Serving:**
|
||||
The server uses `cmux` (connection multiplexer) to serve both gRPC and HTTP on the same port:
|
||||
- **HTTP/2 + `application/grpc`** → Native gRPC server
|
||||
- **HTTP/1.1** → Echo server (REST API via gRPC-Gateway, static files, RSS)
|
||||
|
||||
**API Services** (defined in `proto/api/v1/*.proto`):
|
||||
- `WorkspaceService` - Workspace settings and profiles
|
||||
- `AuthService` - Authentication and session management
|
||||
- `UserService` - User management
|
||||
- `MemoService` - Core memo CRUD operations
|
||||
- `AttachmentService` - File uploads and storage
|
||||
- `InboxService` - Inbox items
|
||||
- `ActivityService` - Activity logging
|
||||
- `MarkdownService` - Markdown utilities (link metadata, etc.)
|
||||
- `IdentityProviderService` - OAuth/SSO providers
|
||||
- `ShortcutService` - User shortcuts
|
||||
|
||||
**API Access Methods:**
|
||||
1. **Native gRPC** - Direct gRPC calls to `memos.api.v1.*` services
|
||||
2. **REST API** - HTTP REST at `/api/v1/*` (via gRPC-Gateway)
|
||||
3. **gRPC-Web** - Browser gRPC calls to `/memos.api.v1.*` (via grpc-web proxy)
|
||||
|
||||
### Database Layer
|
||||
|
||||
**Store Interface:**
|
||||
The `store.Driver` interface (`store/driver.go`) defines all data access methods. Three implementations exist:
|
||||
- `store/db/sqlite/` - SQLite driver (default, embedded database)
|
||||
- `store/db/mysql/` - MySQL driver
|
||||
- `store/db/postgres/` - PostgreSQL driver
|
||||
|
||||
**Migrations:**
|
||||
Each driver contains its own migration files in subdirectories. Schema version tracking is stored in `workspace_setting` (key: `bb.general.version`). The `store/migrator.go` orchestrates migrations across all drivers.
|
||||
|
||||
**Key Models:**
|
||||
- `Memo` - Core note/memo entity
|
||||
- `User` - User accounts
|
||||
- `Attachment` - Uploaded files and images
|
||||
- `MemoRelation` - Graph relationships between memos
|
||||
- `Activity` - Activity log entries
|
||||
- `Inbox` - Inbox items
|
||||
- `Reaction` - Emoji reactions
|
||||
- `WorkspaceSetting` - Workspace-level configuration
|
||||
- `UserSetting` - User preferences
|
||||
- `IdentityProvider` - OAuth/SSO provider configs
|
||||
|
||||
### Frontend Architecture
|
||||
|
||||
**Tech Stack:**
|
||||
- **Framework:** React 18 with TypeScript
|
||||
- **Build Tool:** Vite 7
|
||||
- **Routing:** React Router 7
|
||||
- **State Management:** MobX
|
||||
- **Styling:** Tailwind CSS 4 + Emotion
|
||||
- **UI Components:** Radix UI primitives
|
||||
- **i18n:** react-i18next with language files in `web/src/locales/`
|
||||
|
||||
**State Management:**
|
||||
MobX stores in `web/src/store/` handle global state:
|
||||
- `userStore` - Current user session
|
||||
- `memoStore` - Memo collection and filters
|
||||
- `editorStore` - Memo editor state
|
||||
- `dialogStore` - Modal dialogs
|
||||
- etc.
|
||||
|
||||
**gRPC-Web Client:**
|
||||
The frontend uses `nice-grpc-web` to call backend services. Client setup is in `web/src/grpcweb.ts`.
|
||||
|
||||
### Authentication
|
||||
|
||||
**Dual Auth Support:**
|
||||
1. **Session-based (Cookie):** `user_session` cookie with format `{userID}-{sessionID}`
|
||||
2. **Token-based (JWT):** `Authorization: Bearer <token>` header
|
||||
|
||||
**Flow:**
|
||||
- Authentication interceptor (`server/router/api/v1/acl.go`) runs on all gRPC methods
|
||||
- Public endpoints bypass auth (see `acl_config.go` for allowlist)
|
||||
- Context values set: `userIDContextKey`, `sessionIDContextKey`, `accessTokenContextKey`
|
||||
- Sessions have sliding expiration (14 days from last access)
|
||||
|
||||
## Code Style and Conventions
|
||||
|
||||
### Go
|
||||
|
||||
- **Formatting:** All code must be `gofmt`-compliant (tabs for indentation)
|
||||
- **Imports:** Group stdlib, external, and local imports (enforced by `goimports`)
|
||||
- **Error Handling:** Wrap errors with `%w` when propagating: `errors.Wrap(err, "context")`
|
||||
- **Naming:** Package names lowercase, no underscores
|
||||
- **Linting:** Enforced via `.golangci.yaml` (revive, staticcheck, gocritic, etc.)
|
||||
|
||||
### TypeScript/React
|
||||
|
||||
- **Components:** PascalCase filenames (e.g., `MemoEditor.tsx`)
|
||||
- **Hooks:** camelCase filenames (e.g., `useMemoList.ts`)
|
||||
- **Formatting:** Prettier enforced (see `web/.prettierrc.js`)
|
||||
- **Import Ordering:** Managed by `@trivago/prettier-plugin-sort-imports`
|
||||
- **Styling:** Tailwind utility classes preferred over custom CSS
|
||||
|
||||
### Commit Messages
|
||||
|
||||
Follow Conventional Commits format:
|
||||
- `feat(scope): description` - New features
|
||||
- `fix(scope): description` - Bug fixes
|
||||
- `chore(scope): description` - Maintenance tasks
|
||||
- `refactor(scope): description` - Code restructuring
|
||||
- `test(scope): description` - Test additions/fixes
|
||||
- `docs(scope): description` - Documentation updates
|
||||
|
||||
Scopes: `server`, `api`, `store`, `web`, `proto`, etc.
|
||||
|
||||
## Testing
|
||||
|
||||
**Go Tests:**
|
||||
- Test files: `*_test.go` alongside source files
|
||||
- Run specific package: `go test ./store/cache/...`
|
||||
- API integration tests: `server/router/api/v1/test/*_test.go`
|
||||
- Prefer table-driven tests for multiple test cases
|
||||
|
||||
**Frontend:**
|
||||
Currently relies on linting and manual testing. For UI changes, validate with local dev server.
|
||||
|
||||
## Protocol Buffer Workflow
|
||||
|
||||
**Prerequisites:** Install [buf](https://docs.buf.build/installation)
|
||||
|
||||
**Modifying APIs:**
|
||||
1. Edit `.proto` files in `proto/api/v1/`
|
||||
2. Run `cd proto && buf generate` to regenerate Go and TypeScript code
|
||||
3. Update service implementations in `server/router/api/v1/`
|
||||
4. Update frontend gRPC-Web clients in `web/src/`
|
||||
|
||||
**Generated Code Locations:**
|
||||
- Go: `proto/gen/api/v1/`
|
||||
- TypeScript: `web/src/types/proto/api/v1/`
|
||||
|
||||
## Database Migrations
|
||||
|
||||
When adding database schema changes:
|
||||
|
||||
1. Create migration file in driver-specific directory:
|
||||
- SQLite: `store/db/sqlite/migration/`
|
||||
- MySQL: `store/db/mysql/migration/`
|
||||
- PostgreSQL: `store/db/postgres/migration/`
|
||||
|
||||
2. Follow naming: `prod_YYYYMMDD_description.sql`
|
||||
|
||||
3. Update schema version constant in `store/migrator.go`
|
||||
|
||||
4. Test migration locally with all three database drivers
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Adding a New API Endpoint
|
||||
|
||||
1. Define service method in `proto/api/v1/{service}_service.proto`
|
||||
2. Run `buf generate` to regenerate code
|
||||
3. Implement method in `server/router/api/v1/{service}_service.go`
|
||||
4. Add to public allowlist in `acl_config.go` if unauthenticated
|
||||
5. Update frontend client in `web/src/`
|
||||
|
||||
### Adding a New Data Model
|
||||
|
||||
1. Define struct in `store/{model}.go`
|
||||
2. Add CRUD methods to `store.Driver` interface in `store/driver.go`
|
||||
3. Implement methods in each driver:
|
||||
- `store/db/sqlite/{model}.go`
|
||||
- `store/db/mysql/{model}.go`
|
||||
- `store/db/postgres/{model}.go`
|
||||
4. Create migration files for schema changes
|
||||
5. Add tests in `store/test/{model}_test.go`
|
||||
|
||||
### Frontend Data Fetching
|
||||
|
||||
Use gRPC-Web client from `web/src/grpcweb.ts`:
|
||||
|
||||
```typescript
|
||||
import { memoServiceClient } from "@/grpcweb";
|
||||
|
||||
const response = await memoServiceClient.listMemos({
|
||||
filter: "creator == 'users/1'",
|
||||
});
|
||||
```
|
||||
|
||||
State is typically managed in MobX stores (`web/src/store/`).
|
||||
|
||||
## Production Deployment
|
||||
|
||||
**Docker (Recommended):**
|
||||
```bash
|
||||
docker run -d \
|
||||
--name memos \
|
||||
-p 5230:5230 \
|
||||
-v ~/.memos:/var/opt/memos \
|
||||
neosmemo/memos:stable
|
||||
```
|
||||
|
||||
**From Source:**
|
||||
1. Build frontend: `cd web && pnpm install && pnpm release`
|
||||
2. Build backend: `go build -o memos ./cmd/memos`
|
||||
3. Run: `./memos --mode prod --port 5230`
|
||||
|
||||
**Data Directory:**
|
||||
For SQLite (default), all data is stored in the directory specified by `--data` flag. This includes:
|
||||
- `memos_prod.db` - SQLite database
|
||||
- `assets/` - Uploaded files (unless using S3-compatible storage)
|
||||
|
||||
