```

## Quick Start

### 1. Start Backend

```bash
cd server
```

Edit `application.properties` to set the `active` environment, then edit `application-{active}.properties` to configure database connection and other settings:

```properties
# application.properties
active=dev
# application-dev.properties
server.port=8080
database.host=127.0.0.1
database.port=3306
database.name=kenaito_conf
database.user=root
database.password=your_password
jwt.secret=your-jwt-secret
jwt.expireHours=24
```

Start the service (tables and default data will be initialized automatically on first startup):

```bash
go run cmd/main.go -config application.properties
# Or build and run
go build -o bin/server cmd/main.go
./bin/server -config application.properties
```

The backend listens on `:8080` by default.

### 2. Start Frontend

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

The frontend listens on `:3000` by default and automatically proxies API requests to the backend.

### 3. Access

Open http://localhost:3000

Default admin credentials: `admin` / Password: `admin123`

## Client Integration

### Go Client

```go
import client "kenaito-conf/go-client"

cfg := &client.Config{
    BaseURL:      "http://localhost:8080",
    AppName:      "myapp",
    Env:          "dev",
    Version:      "latest",
    Token:        "app-token",
    SyncInterval: 30,
    CacheDir:     ".",
}

c := client.New(cfg)

// Register change callback
c.OnChange(func (changed map[string]string) {
    for k, v := range changed {
        fmt.Printf("%s = %s\n", k, v)
    }
})

// Start (fetch all configs + enable periodic sync)
c.Start()
defer c.Stop()

// Read configuration
dbHost := c.Get("db.host")
```

### Java Spring Boot 2.x Client

Suitable for JDK 8+ and Spring Boot 2.x projects, supports automatic config refresh and dynamic `@Value` updates.

**1. Add Dependency**

```xml
<dependency>
    <groupId>cn.odboy</groupId>
    <artifactId>kenaito-conf-springboot2-client</artifactId>
    <version>1.0.3</version>
</dependency>
```

**2. Add Configuration** (`application.properties`)

```properties
# Config center settings
kenaito.configcenter.base-url=http://localhost:8080
# Application name (required)
kenaito.configcenter.app-name=myapp
# Environment (dev/daily/prod)
kenaito.configcenter.env=daily
# Config version
kenaito.configcenter.version=latest
# Auth token (optional)
kenaito.configcenter.token=app-token
# Sync interval (seconds)
kenaito.configcenter.sync-interval=30
```

**3. Use Configuration**

```java
@Value("${database.host:localhost}")
private String databaseHost;

@Value("${database.port:3306}")
private Integer databasePort;
```

`@Value` fields are automatically refreshed when configuration changes, no application restart required. See [Spring Boot 2 Client Documentation](kenaito-conf-springboot2-client/README.md) for details.

### Python Client

Suitable for Python 3.10+ projects.

**1. Install**

```bash
cd kenaito-conf-python-client

    app_name="my-app",
    env="daily",
    sync_interval=30,
)

client = ConfigClient(config)

# Listen for config changes
def on_change(changed):
    for k, v in changed.items():
        print(f"config changed: {k} = {v}")

client.on_change(on_change)

# Start client (fetch configs + enable periodic sync)
client.start()

# Get configuration
value = client.get("database.host")
all_configs = client.get_all()

# Stop
client.stop()
```

### Node.js Client

    env: 'daily',
    syncInterval: 30,
});

const client = new ConfigClient(config);

// Listen for config changes
client.onChange((changed) => {
    for (const [k, v] of Object.entries(changed)) {
        console.log(`config changed: ${k} = ${v}`);
    }
});

// Start client (fetch configs + enable periodic sync)
await client.start();

// Get configuration
