How to set up the development environment and contribute to OwnCord.

Development Setup

Prerequisites

Platform	Server	Client
Windows 10+ x64	✅	✅
Linux x64	✅	✅
Linux ARM64	✅	✅ (CI only)

• Go 1.25+ (server)
• Node.js 20+ (client)
• Rust / Cargo (Tauri client — not needed for server-only work)
• Docker + Compose v2 (optional — alternative to building the server locally)

Available Commands

Server (Go)

Command	Description
go build -o chatserver.exe -ldflags "-s -w" .	Build server binary (Windows)
CGO_ENABLED=0 go build -o chatserver -ldflags "-s -w" .	Build server binary (Linux)
go build -tags otel .	Build with OpenTelemetry SDK (requires go get first — see Phase B)
go build -tags wazero .	Build with Wazero plugin runtime (requires go get first — see Phase C)
go build -tags postgres .	Build with PostgreSQL backend (requires pgx in go.mod)
go test ./...	Run all server tests
go test ./... -cover	Run server tests with coverage
go test -race ./...	Run server tests with race detection

Make targets (run from Server/):

Command	Description
make sqlc-install	Install the pinned sqlc version into $GOBIN
make sqlc-generate	Regenerate type-safe Go for both SQLite (db/dbgen/) and PostgreSQL (db/pgdbgen/) engines
make sqlc-verify	Fail if committed dbgen / pgdbgen output is stale (used by CI)
make otel-up	Start Jaeger (traces) + Prometheus (metrics) via Docker for local OTel development
make otel-down	Stop and remove the OTel dev containers

Client (Tauri v2)

Build & dev

Command	Description
npm run dev	Start Vite dev server with hot reload
npm run build	TypeScript check + Vite production build
npm run tauri dev	Launch Tauri app in dev mode
npm run tauri build	Build release installer (NSIS on Windows, AppImage+deb on Linux)

Tests

Command	Description
npm test	Run all tests (vitest)
npm run test:unit	Unit tests only
npm run test:integration	Integration tests only
npm run test:e2e	Playwright E2E (mocked Tauri)
npm run test:e2e:native	Playwright E2E (real Tauri exe + CDP)
npm run test:e2e:prod	Playwright E2E (prod build)
npm run test:e2e:ui	Playwright UI mode
npm run test:watch	Vitest watch mode
npm run test:coverage	Coverage report
npm run test:mutate	Stryker mutation testing
npm run test:mutate:dry	Stryker dry-run (no mutations applied)
npm run test:browser	Vitest browser-mode tests

Type checking, linting & formatting

Command	Description
npm run typecheck	Full typecheck (all sources)
npm run typecheck:build	Typecheck build config only
npm run lint	oxlint + ESLint check (src/)
npm run lint:fix	ESLint auto-fix
npm run lint:ox	oxlint only (fast correctness checks)
npm run format	Prettier format (src/ + tests/)
npm run format:check	Prettier check only (no writes)
npm run knip	Dead code and unused export detection

Plugin Development

Plugins are WASM modules loaded at runtime when the server is built with -tags wazero. See Server/plugin/examples/hello/README.md for the full plugin ABI and build instructions.

Toolchain requirements for building .wasm plugins with TinyGo:

Tool	Version	Notes
TinyGo	0.40.1	Supports Go 1.19–1.25 only
Go SDK	1.25.x	Install alongside the system Go via go install golang.org/dl/go1.25.3@latest && go1.25.3 download
wasm-opt	Binaryen 129	Required by TinyGo for the wasi target; download from Binaryen GitHub releases

Any WASM toolchain (Rust/wasm32-wasi, AssemblyScript, etc.) that exports the five ABI functions is equally valid — TinyGo is just the example toolchain used by examples/hello/.

Active Branches

• main -- stable releases
• dev -- active development

Branch Naming

• feature/<name> -- new features
• fix/<name> -- bug fixes
• docs/<name> -- documentation changes

Commit Format

Use conventional commits:

feat: add thread support to channels
fix: prevent duplicate WebSocket connections
refactor: extract permission checks into middleware
docs: update quick-start guide
test: add integration tests for invite flow
chore: bump Go dependencies
perf: cache role permissions in memory
ci: add lint step to GitHub Actions

Pull Request Process

1. Branch from main
2. PRs target main; releases are cut from tagged commits on main
3. CI must pass (build + test + lint)
4. Request code review
5. Squash merge preferred

Testing

Target 80%+ coverage. Follow test-driven development workflow.

Code Style

• TypeScript: See Client Architecture
• Go: gofmt + golangci-lint, standard library preferred
• Rust: cargo fmt + cargo clippy, minimal code (native APIs only)
