Stack
- Backend: go-zero, DDD layering, sqlc, pgx, PostgreSQL optional persistence
- Cache: memory or Redis, default memory
- Agent: sky-valley/pi Go agent runtime adapter, local desktop agent disabled
- Image storage: memory, MinIO, AWS S3, Cloudflare R2, Aliyun OSS
- Frontend: Next.js App Router, pnpm, Vite artifact build, TypeScript, gzip, i18n
- Deploy: local binary, Docker Compose, k3s manifests
Run Locally
Backend:
cd server
go mod tidy
go run . -f etc/config.yaml
Frontend:
cd frontend
pnpm install
pnpm dev
Open http://localhost:5173. Next.js rewrites /api to http://localhost:8888 in development. pnpm build runs next build and vite build, producing gzip assets in frontend/dist.
Cache Config
Default in-memory cache:
Cache:
Driver: memory
TTLSeconds: 300
Redis cache:
Cache:
Driver: redis
Addr: localhost:6379
Password: ""
DB: 0
TTLSeconds: 300
Storage Config
Default memory storage is useful for local UI work:
Storage:
Driver: memory
Image Object Storage
Default memory mode is useful for local prototyping. Production can use MinIO, AWS S3, Cloudflare R2, or Aliyun OSS:
ObjectStorage:
Driver: minio # memory|minio|s3|aws|r2|aliyun
Bucket: canvas-assets
Endpoint: localhost:9000
Region: us-east-1
AccessKey: canvas
SecretKey: canvas-secret
PublicBase: http://localhost:9000/canvas-assets
UseSSL: false
ExpiresIn: 900
PostgreSQL storage:
Storage:
Driver: postgres
DataSource: postgres://canvas:canvas@localhost:5432/canvas?sslmode=disable
Docker Compose
cd deploy
docker compose up --build
Open http://localhost:3000.
k3s
Build and load/push these images first:
docker build -t img-infinite-canvas-api:latest server
docker build -t img-infinite-canvas-web:latest frontend
kubectl apply -f deploy/k3s/img-infinite-canvas.yaml
The sample ingress host is canvas.local.
