root 44406b72db Initial commit: img-infinite-canvas AI design workbench MVP

Moteva-style AI design workbench replica. Home prompt creates a project;
the project page provides an infinite canvas with node drag, zoom/pan,
a design chat panel, history replay, image asset upload, and project
save/regenerate.

- Backend: go-zero, DDD layering, sqlc/pgx, optional PostgreSQL; memory
  or Redis cache; asynq job queue; MinIO/S3/R2/OSS object storage;
  sky-valley/pi agent runtime adapter.
- Frontend: Next.js App Router + Vite artifact build, TypeScript, i18n,
  shadcn/ui components, auth (OTP/Turnstile/Google/WeChat).
- Deploy: Docker Compose and k3s manifests.

img-infinite-canvas

Moteva 风格的 AI 设计工作台复刻 MVP：主页 Prompt 创建项目，项目页提供无限画布、节点拖拽、缩放平移、右侧设计对话、历史回放、图片资产上传、项目保存与再生成。

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.

API

See server/API.md.
