Thanks for your interest in contributing to DS2API!

Development Setup

Prerequisites

• Go 1.24+
• Node.js 20+ (for WebUI development)
• npm (bundled with Node.js)

Backend Development

# 1. Clone
git clone https://github.com/CJackHwang/ds2api.git
cd ds2api

# 2. Configure
cp config.example.json config.json
# Edit config.json with test accounts

# 3. Run backend
go run ./cmd/ds2api
# Default: http://localhost:5001

Frontend Development (WebUI)

# 1. Navigate to WebUI directory
cd webui

# 2. Install dependencies
npm install

# 3. Start dev server (hot reload)
npm run dev
# Default: http://localhost:5173, auto-proxies API to backend

WebUI tech stack:

• React + Vite
• Tailwind CSS
• Bilingual language packs: webui/src/locales/zh.json / en.json

Docker Development

docker-compose -f docker-compose.dev.yml up

Code Standards

Language	Standards
Go	Run gofmt and ensure go test ./... passes before committing
JavaScript/React	Follow existing project style (functional components)
Commit messages	Use semantic prefixes: feat:, fix:, docs:, refactor:, style:, perf:, chore:

Submitting a PR

1. Fork the repo
2. Create a branch (e.g. feature/xxx or fix/xxx)
3. Commit changes
4. Push your branch
5. Open a Pull Request

💡 If you modify files under webui/, no manual build is needed — CI handles it automatically.

Build WebUI

Manually build WebUI to static/admin/:

./scripts/build-webui.sh

Running Tests

# Go unit tests
go test ./...

# End-to-end live tests (real accounts)
./scripts/testsuite/run-live.sh
