# GitM Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Build a cross-platform Gitea repository sync tool with a single-binary Go backend and embedded Vue 3 frontend

**Architecture:** Go (Gin) backend with SQLite storage, Vue 3 + Element Plus frontend embedded via Go embed, JWT authentication, Gitea API integration for repo discovery and git-based mirroring

**Tech Stack:** Go 1.26+, Gin, SQLite (mattn/go-sqlite3), Vue 3, Element Plus, Pinia, Vite, golang-jwt/jwt, bcrypt

***

## Phase 1: Project Initialization and Core Infrastructure

### Task 1: Initialize Go Module and Project Structure

**Files:**

- Create: `go.mod`
- Create: `go.sum` (auto-generated)
- Create: `Makefile`
- Create: `main.go`
- Create: `README.md`
- [ ] **Step 1: Initialize Go module**

```bash
cd /c/electron/gitm
go mod init gitm
```

- [ ] **Step 2: Create go.mod with dependencies**

Create `go.mod`:

```go
module gitm

go 1.26

require (
	github.com/gin-gonic/gin v1.10.0
	github.com/mattn/go-sqlite3 v1.14.22
	github.com/golang-jwt/jwt/v5 v5.2.1
	golang.org/x/crypto v0.25.0
	github.com/robfig/cron/v3 v3.0.1
)
```

- [ ] **Step 3: Download dependencies**

```bash
go mod tidy
```

Expected: `go.sum` created, dependencies downloaded

- [ ] **Step 4: Create Makefile**

Create `Makefile`:

```makefile
.PHONY: all build frontend clean test run

# Build frontend first, then build the binary
all: frontend build

# Build Vue frontend
frontend:
	cd web && npm install && npm run build

# Build Go binary
build:
	go build -o bin/gitm .

# Clean build artifacts
clean:
	rm -rf bin/
	rm -rf web/dist/
	rm -rf web/node_modules/

# Run tests
test:
	go test -v ./...

# Run the application
run:
	go run main.go

# Cross-compile for Linux
build-linux:
	GOOS=linux GOARCH=amd64 go build -o bin/gitm-linux .

# Cross-compile for Windows
build-windows:
	GOOS=windows GOARCH=amd64 go build -o bin/gitm.exe .
```

- [ ] **Step 5: Create main.go skeleton**

Create `main.go`:

```go
package main

import (
	"flag"
	"fmt"
	"log"
)

var (
	flagAddr    = flag.String("addr", ":9000", "Listen address")
	flagDataDir = flag.String("data", "./data", "Data directory")
	flagInit    = flag.Bool("init", false, "Initialize database and set password")
)

func main() {
	flag.Parse()

	fmt.Printf("GitM - Gitea Repository Sync Tool\n")
	fmt.Printf("Listen: %s\n", *flagAddr)
	fmt.Printf("Data: %s\n", *flagDataDir)

	if *flagInit {
		fmt.Println("Initialize mode: TODO")
		return
	}

	log.Fatal(runServer())
}

func runServer() error {
	// TODO: implement server
	return fmt.Errorf("not implemented")
}
```

- [ ] **Step 6: Create README.md**

Create `README.md`:

````markdown
# GitM - Gitea Repository Sync Tool

Cross-platform tool to synchronize all repositories from multiple Gitea servers to local storage.

## Features

- Single binary deployment
- Web UI for management (Vue 3 + Element Plus)
- SQLite database
- JWT authentication
- Scheduled and manual sync
- Cross-platform (Windows, Linux)

## Build

```bash
make all
````

## Run

```bash
# First run - initialize
./bin/gitm --init

# Normal run
./bin/gitm

# Custom port
./bin/gitm --addr :9090
```

## Development

```bash
# Install frontend deps
cd web && npm install

# Run frontend dev server
cd web && npm run dev

# Run backend (requires frontend built first)
go run main.go
```

````

- [ ] **Step 7: Commit**

```bash
git add go.mod go.sum Makefile main.go README.md
git commit -m "feat: initialize project structure and dependencies"
````

***

### Task 2: Create Internal Package Structure

**Files:**

- Create: `internal/config/config.go`
- Create: `internal/models/models.go`
- [ ] **Step 1: Create config package**

Create `internal/config/config.go`:

```go
package config

import (
	"os"
	"path/filepath"
	"sync"
)

type Config struct {
	ListenAddr string
	DataDir    string
	DBPath     string
	ReposDir   string
	once       sync.Once
}

var (
	instance *Config
	initOnce sync.Once
)

func Get() *Config {
	initOnce.Do(func() {
		instance = &Config{
			ListenAddr: ":9000",
			DataDir:    "./data",
		}
	})
	return instance
}

func (c *Config) SetDataDir(dir string) {
	c.DataDir = dir
	c.DBPath = filepath.Join(dir, "gitm.db")
	c.ReposDir = filepath.Join(dir, "repos")
}

func (c *Config) EnsureDirs() error {
	if err := os.MkdirAll(c.DataDir, 0755); err != nil {
		return err
	}
	return os.MkdirAll(c.ReposDir, 0755)
}
```

- [ ] **Step 2: Create models package**

Create `internal/models/models.go`:

```go
package models

import "time"

// GiteaServer represents a Gitea server configuration
type GiteaServer struct {
	ID           int64      `json:"id" db:"id"`

	CreatedAt  time.Time  `json:"created_at" db:"created_at"`
}

// SyncLog represents a sync operation log
type SyncLog struct {
	ID         int64      `json:"id" db:"id"`
	ServerID   int64      `json:"server_id" db:"server_id"`

}

// SyncStatus represents the current sync state
type SyncStatus struct {
	ServerID  int64  `json:"server_id"`
	Status    string `json:"status"` // idle, syncing, failed
	TaskID    string `json:"task_id,omitempty"`
	StartedAt string `json:"started_at,omitempty"`
}
```

- [ ] **Step 3: Commit**

- [ ] **Step 2: Fix imports and issues**

Edit `internal/sync/engine.go`:

```go
package sync

import (
	"fmt"
	"os"
	"os/exec"
	"path/filepath"
	"sync"
	"time"

	"gitm/internal/database"
	db "gitm/internal/database"
	"gitm/internal/gitea"
)
```

- [ ] **Step 3: Create scheduler**

Create `internal/sync/scheduler.go`:

```go
package sync

import (
	"log"
	"time"

	"github.com/robfig/cron/v3"
	"gitm/internal/database"
)

// Scheduler manages scheduled sync tasks

		return err
	}

	for _, server := range servers {

}
```

- [ ] **Step 4: Add missing import to scheduler**

Edit `internal/sync/scheduler.go`:

```go
import (
	"fmt"
	"log"
	"time"

	"github.com/robfig/cron/v3"
	"gitm/internal/database"
)
```

- [ ] **Step 5: Test compilation**

```bash
go build -o /tmp/gitm-test .

Expected: Success

- [ ] **Step 6: Commit**

```bash
git add internal/sync/
git commit -m "feat: implement sync engine and scheduler"

## Phase 5: Frontend Build Integration

### Task 17: Embed Frontend in Go Binary

**Files:**

- Modify: `main.go`
- Modify: `Makefile`
- [ ] **Step 1: Add embed directive to main.go**

Edit `main.go`, add after the imports:

```go
//go:embed web/dist
var webFS embed.FS
```

And add `"embed"` and `"io/fs"` to imports:

```go
import (
	"embed"
	"flag"
	"fmt"
	"io/fs"
	"log"
	"os"

	"github.com/gin-gonic/gin"
	"golang.org/x/crypto/bcrypt"
	"gitm/internal/config"
	"gitm/internal/database"
	"gitm/internal/handler"
	"gitm/internal/middleware"
	"gitm/internal/sync"
)
```

- [ ] **Step 2: Serve embedded frontend**

Edit `main.go`, update the `runServer` function. Find the comment about static files and replace with:

```go
	// Serve embedded frontend
	distFS, err := fs.Sub(webFS, "web/dist")
	if err != nil {
		return fmt.Errorf("failed to create sub filesystem: %w", err)
	}
	r.StaticFS("/", http.FS(distFS))
	// API routes fallback for SPA
	r.NoRoute(func(c *gin.Context) {
		c.FileFromFS("/", http.FS(distFS))
	})
```

- [ ] **Step 3: Add** **`"net/http"`** **to imports**

Edit `main.go` imports:

```go
import (
	"embed"
	"flag"
	"fmt"
	"io/fs"
	"log"
	"net/http"
	"os"

	"github.com/gin-gonic/gin"
	"golang.org/x/crypto/bcrypt"
	"gitm/internal/config"
	"gitm/internal/database"
	"gitm/internal/handler"
	"gitm/internal/middleware"
	"gitm/internal/sync"
)
```

- [ ] **Step 4: Update runServer function**

Edit `main.go`, update `runServer` to serve static files correctly:

```go
func runServer(cfg *config.Config, engine *sync.Engine, scheduler *sync.Scheduler) error {
	gin.SetMode(gin.ReleaseMode)
	r := gin.Default()

	// Serve embedded frontend
	distFS, err := fs.Sub(webFS, "web/dist")
	if err == nil {
		// Try to serve embedded files first
		r.StaticFS("/assets", http.FS(distFS))
		r.NoRoute(func(c *gin.Context) {
			c.Request.URL.Path = "/"
			c.FileFromFS("/", http.FS(distFS))
		})
	} else {
		// Fallback to local files for development
		r.Static("/", "./web/dist")
		r.NoRoute(func(c *gin.Context) {
			c.File("./web/dist/index.html")
		})
	}

	// API routes
	api := r.Group("/api")
	{
		// Public routes
		api.POST("/login", handler.HandleLogin)
		api.POST("/init", handler.HandleInit)

		// Protected routes
		protected := api.Group("")
		protected.Use(middleware.AuthMiddleware())
		{
			// Settings
			protected.GET("/settings", handler.HandleGetSettings)
			protected.PUT("/settings", handler.HandleUpdateSettings)

			// Servers
			protected.GET("/servers", handler.HandleListServers)
			protected.POST("/servers", handler.HandleCreateServer)
			protected.PUT("/servers/:id", handler.HandleUpdateServer)
			protected.DELETE("/servers/:id", handler.HandleDeleteServer)
			protected.POST("/servers/:id/test", handler.HandleTestConnection)
			protected.GET("/servers/:id/repos", handler.HandleListRepos)
			protected.POST("/servers/:id/discover", handler.HandleDiscoverRepos)
			protected.POST("/servers/:id/sync", handler.HandleSyncServer(engine))
			protected.GET("/servers/:id/sync/status", handler.HandleGetSyncStatus(engine))

			// Sync
			protected.POST("/sync/all", handler.HandleSyncAll(engine))

			// Logs and stats
			protected.GET("/sync/logs", handler.HandleGetSyncLogs)
			protected.GET("/sync/stats", handler.HandleGetStats)
		}
	}

	return r.Run(cfg.ListenAddr)
}
```

- [ ] **Step 5: Update Makefile**

Edit `Makefile` to fix build order:

```makefile
.PHONY: all build frontend clean test run

# Build frontend first, then build the binary
all: frontend build

# Build Vue frontend
frontend:
	cd web && npm install && npm run build

# Build Go binary (requires frontend built)
build:
	go build -o bin/gitm .

# Clean build artifacts
clean:
	rm -rf bin/
	rm -rf web/dist/
	rm -rf web/node_modules/

# Run tests
test:
	go test -v ./...

# Run the application (development mode with local frontend)
run-dev:
	cd web && npm run dev

# Run the built binary
run:
	./bin/gitm

# Cross-compile for Linux
build-linux:
	GOOS=linux GOARCH=amd64 go build -o bin/gitm-linux .

# Cross-compile for Windows
build-windows:
	GOOS=windows GOARCH=amd64 go build -o bin/gitm.exe .
```

- [ ] **Step 6: Test build**

```bash
cd web && npm install && npm run build
cd ..
go build -o bin/gitm .
```

Expected: Success, `bin/gitm` created

- [ ] **Step 7: Commit**

```bash
git add main.go Makefile
git commit -m "feat: embed frontend in Go binary"
```

***

## Phase 6: Testing and Documentation

### Task 18: Create Tests

**Files:**

- Create: `internal/database/database_test.go`
- Create: `internal/gitea/client_test.go`
- [ ] **Step 1: Create database tests**

Create `internal/database/database_test.go`:

		value, err := GetSetting("test_key")
		if err != nil {
			t.Errorf("Failed to get setting: %v", err)
		}
		if value != "test_value" {
			t.Errorf("Expected test_value, got %s", value)
		}
	})

	// Test server CRUD
	t.Run("ServerCRUD", func(t *testing.T) {
		server := &GiteaServer{
			Name:         "Test Server",
			URL:          "https://test.com",
			Token:        "test-token",
			SyncInterval: 60,
			Status:       "active",
		}

		// Create
		if err := CreateServer(server); err != nil {
			t.Errorf("Failed to create server: %v", err)
		}
		if server.ID == 0 {
			t.Error("Expected server ID to be set")
		}

		// Read
		fetched, err := GetServer(server.ID)
		if err != nil {
			t.Errorf("Failed to get server: %v", err)
		}
		if fetched.Name != server.Name {
			t.Errorf("Expected %s, got %s", server.Name, fetched.Name)
		}

		// Update
		fetched.Name = "Updated Server"
		if err := UpdateServer(fetched); err != nil {
			t.Errorf("Failed to update server: %v", err)
		}

		// List
		servers, err := GetServers()
		if err != nil {
			t.Errorf("Failed to list servers: %v", err)
		}
		if len(servers) != 1 {
			t.Errorf("Expected 1 server, got %d", len(servers))
		}

		// Delete
		if err := DeleteServer(server.ID); err != nil {
			t.Errorf("Failed to delete server: %v", err)
		}
	})
}
```

- [ ] **Step 2: Run tests**

```bash
go test ./internal/database/... -v
```

Expected: All tests pass

- [ ] **Step 3: Create Gitea client tests**

Create `internal/gitea/client_test.go`:

```go
package gitea

import (
	"testing"
)

func TestNewClient(t *testing.T) {
	client, err := NewClient("https://gitea.com", "")
	if err != nil {
		t.Errorf("Failed to create client: %v", err)
	}
	if client == nil {
		t.Error("Expected client to be created")
	}
}

func TestNewClientInvalidURL(t *testing.T) {
	_, err := NewClient("://invalid", "")
	if err == nil {
		t.Error("Expected error for invalid URL")
	}
}
```

- [ ] **Step 4: Run tests**

```bash
go test ./internal/gitea/... -v
```

Expected: All tests pass

- [ ] **Step 5: Commit**

```bash
git add internal/database/database_test.go internal/gitea/client_test.go
git commit -m "test: add unit tests for database and Gitea client"
```

### Task 19: Final Documentation

**Files:**

- Modify: `README.md`
- Create: `.gitignore`
- [ ] **Step 1: Update README.md**

Replace `README.md` with:

````markdown
# GitM - Gitea Repository Sync Tool

Cross-platform tool to synchronize all repositories from multiple Gitea servers to local storage.

## Features

- **Single Binary**: One executable file contains everything
- **Web UI**: Vue 3 + Element Plus management interface
- **SQLite Storage**: Lightweight, portable database
- **JWT Authentication**: Secure token-based auth
- **Scheduled Sync**: Automatic sync with configurable intervals
- **Manual Sync**: On-demand sync for any server
- **Cross-Platform**: Runs on Windows and Linux
- **Mirror Clone**: Uses `git clone --mirror` for complete backup

## Quick Start

### Build

```bash
# Clone the repository
git clone <repository-url>
cd gitm

# Build everything (frontend + backend)
make all

# The binary will be at bin/gitm
````

### First Run

```bash
# Initialize and set admin password
./bin/gitm --init

# Start the server (default port 9000)
./bin/gitm

# Or specify custom port
./bin/gitm --addr :9090
```

### Access Web UI

Open your browser and navigate to:

- <http://localhost:9000> (default)
- <http://localhost:9090> (if you used --addr :9090)

## Usage

### Adding a Gitea Server

1. Log in with the password you set during initialization
2. Go to **Servers** page
3. Click **Add Server**
4. Fill in:
   - **Name**: A friendly name for this server
   - **URL**: The Gitea server URL (e.g., `https://git.example.com`)
   - **Token**: Your Gitea API access token
   - **Sync Interval**: Minutes between automatic syncs (0 = manual only)
5. Click **Test Connection** to verify
6. Click **Save**

### Creating a Gitea API Token

1. Log into your Gitea instance
2. Go to **Settings** → **Applications**
3. Click **Generate New Token**
4. Give it a name and select **read** permission for repositories
5. Copy the token (you won't see it again!)

### Syncing Repositories

There are two ways to sync:

1. **Automatic**: Set a sync interval (in minutes) when adding a server
2. **Manual**: Click the **Sync** button on the Servers page

To discover new repositories without syncing, click **Discover**.

### Storage

Repositories are stored as bare git mirrors at:

```
<data_dir>/repos/server_<id>_<name>/<owner>/<repo>.git
```

Default data directory is `./data` relative to the binary.

## Configuration

Settings are stored in the SQLite database and can be changed via the Web UI:

- **Admin Password**: Change your login password
- **Listen Address**: Port to listen on (requires restart)
- **Repos Directory**: Where to store cloned repositories
- **Max Concurrent Sync**: Maximum parallel sync operations

## API Endpoints

The API is available at `/api/` and requires JWT authentication:

### Authentication

- `POST /api/login` - Authenticate and get token
- `POST /api/init` - Initialize admin password

### Settings

- `GET /api/settings` - Get all settings
- `PUT /api/settings` - Update settings

### Servers

- `GET /api/servers` - List all servers
- `POST /api/servers` - Add a server
- `PUT /api/servers/:id` - Update a server
- `DELETE /api/servers/:id` - Delete a server
- `POST /api/servers/:id/test` - Test connection
- `GET /api/servers/:id/repos` - List repositories
- `POST /api/servers/:id/discover` - Discover repositories
- `POST /api/servers/:id/sync` - Trigger sync
- `GET /api/servers/:id/sync/status` - Get sync status

### Sync

- `POST /api/sync/all` - Sync all servers
- `GET /api/sync/logs` - Get sync logs
- `GET /api/sync/stats` - Get statistics

## Development

### Prerequisites

- Go 1.26+
- Node.js 18+
- npm

### Frontend Development

```bash
cd web
npm install
npm run dev
```

The dev server runs on <http://localhost:5173> with API proxy to :9000.

### Backend Development

```bash
go run main.go
```

### Running Tests

```bash
go test ./...
```

## Security Notes

- Gitea API tokens are stored encrypted in the database
- JWT tokens expire after 24 hours
- By default, the server listens on localhost only
- Change the default JWT secret in production

Create `.gitignore`:

```

# Binaries

bin/
gitm
gitm.exe
gitm-linux

# Data

data/
\*.db
\*.db-shm
\*.db-wal

# Go

\*.exe
\*.exe\~
\*.dll
\*.so
\*.dylib
\*.test
\*.out
go.work

# Node

web/node\_modules/
web/dist/

# IDE

.idea/
.vscode/
\*.swp
\*.swo
\*\~

# OS

.DS\_Store
Thumbs.db

# Temporary

\*.log
\*.tmp

````

- [ ] **Step 3: Commit**

```bash
git add README.md .gitignore
git commit -m "docs: update README and add .gitignore"
````

## Task 20: Final Build Verification

**Files:**

- None (verification task)
- [ ] **Step 1: Full clean build**

```bash
make clean
make all
```

Expected: Clean build completes successfully

- [ ] **Step 2: Verify binary works**

```bash
./bin/gitm --help
```

Expected: Shows usage or starts server

- [ ] **Step 3: Test initialization**

```bash
rm -rf data/
./bin/gitm --init
# Enter: testpassword123
```

Expected: "Initialized successfully!"

- [ ] **Step 4: Quick functional test**

```bash
# Start server in background
./bin/gitm &
SERVER_PID=$!

# Wait for startup
sleep 2

# Test API (login)
curl -X POST http://localhost:9000/api/login \
  -H "Content-Type: application/json" \
  -d '{"password":"testpassword123"}'

# Kill server
kill $SERVER_PID
```

Expected: Returns `{"token":"..."}`

- [ ] **Step 5: Cross-compile test**

```bash
make build-linux
make build-windows
ls -lh bin/
```

Expected: `gitm-linux` and `gitm.exe` created

- [ ] **Step 6: Final commit**

```bash
git add -A
git commit -m "chore: final build verification complete"
```
