wavelet

🚀 A modern, production-ready full-stack boilerplate for building scalable web applications

中文

📖 Introduction

wavelet is a generic, production-ready full-stack boilerplate built with Go (Gin + GORM) on the backend and Next.js (App Router + Shadcn UI) on the frontend. It ships with everything you need to bootstrap a modern SaaS, internal tool, or developer platform — without the boilerplate headaches.

The project was designed from the ground up to be framework-first and business-agnostic: plug in your own domain logic while reusing the battle-tested infrastructure that comes out of the box.

✨ Key Features

• 🔐 Multi-auth System — Local password login/registration + pluggable OIDC/OAuth2 providers (supports multiple auth sources simultaneously)
• 🗝️ Personal Access Tokens — API key management for programmatic access; supports Authorization: Bearer and X-Access-Token headers
• 👤 User Management — Admin panel for listing, searching, filtering, enabling/disabling user accounts
• ⚙️ Dynamic System Config — Key-value system configuration management with live reload, controllable from the admin UI
• 📋 Async Task Queue — Background job processing with Asynq (Redis-backed), including a scheduling dashboard
• 📁 S3 File Storage — Unified file upload/download via S3-compatible APIs with local disk cache
• 📊 Observability — Structured logging (Zap) + distributed tracing (OpenTelemetry)
• 🎨 Modern UI — Responsive, dark-mode-ready design system built with Tailwind CSS 4 and Shadcn UI
• 📖 Built-in Documentation — Integrated docs portal with usage guides, API reference, privacy policy, and terms of service

🛠️ Tech Stack

Backend

• Go 1.25+ — Primary language
• Gin — HTTP web framework
• GORM — ORM with PostgreSQL & ClickHouse support
• Redis — Cache, session store, and task queue backend
• Asynq — Distributed task queue (Redis-backed)
• Cobra + Viper — CLI entrypoint and configuration management
• OpenTelemetry — Distributed tracing and observability
• Zap — Structured, high-performance logging
• Swagger (Swaggo) — Auto-generated API documentation
• AWS SDK v2 — S3-compatible file storage
• Snowflake — Distributed ID generation

Frontend

• Next.js 16 — React framework with App Router
• React 19 — UI library
• TypeScript — Type safety
• Tailwind CSS 4 — Utility-first styling
• Shadcn UI — Accessible, composable component library
• Lucide Icons — Icon library

📋 Requirements

• Go >= 1.25
• Node.js >= 18.0
• PostgreSQL >= 14
• Redis >= 6.0
• pnpm >= 8.0 (recommended)

🚀 Quick Start

1. Clone the Repository

git clone https://github.com/Rain-kl/Wavelet.git refreshing
cd refreshing

2. Configure Environment

cp config.example.yaml config.yaml

Edit config.yaml to configure your database and Redis. OIDC auth sources are configured at runtime in the admin settings page.

3. Initialize Database

# Start local dependencies (PostgreSQL + Redis)
docker compose up -d

# Optional: also start ClickHouse
docker compose --profile clickhouse up -d

# If you use an external PostgreSQL instance instead of Docker, create the database manually
createdb -h <host> -p 5432 -U postgres refreshing

# Database schema is auto-migrated on first startup

4. Start the Backend

# Install Go dependencies
go mod tidy

# Generate Swagger API documentation
make swagger

# Start the HTTP API server
go run main.go api

The backend also supports separate scheduler and worker processes for async task processing:

go run main.go scheduler   # Cron job scheduler
go run main.go worker      # Asynq task worker

5. Start the Frontend

cd frontend

# Install dependencies
pnpm install

# Start dev server (Turbopack)
pnpm dev

6. Access the Application

Service	URL
Frontend	http://localhost:3000
Swagger API Docs	http://localhost:8000/swagger/index.html
Health Check	http://localhost:8000/api/health

⚙️ Configuration

Key configuration options (see config.example.yaml for the full reference):

Option	Description	Example
app.addr	Backend listen address	:8000
database.host	PostgreSQL host	127.0.0.1
database.database	Database name	refreshing
redis.host	Redis host	127.0.0.1
storage.endpoint	S3-compatible endpoint	s3.amazonaws.com

📚 API Documentation

Swagger API documentation is auto-generated and available once the backend is running:

http://localhost:8000/swagger/index.html

The built-in frontend docs portal at /docs includes:

• Usage Guide — Step-by-step walkthrough for getting started
• API Reference — Detailed interface documentation
