# Controller

<figure><img src="/files/VpT6zfcNTk0l0pzlMhyQ" alt=""><figcaption></figcaption></figure>

A controller's purpose is to receive specific requests for the application. The **routing** mechanism controls which controller receives which requests. Frequently, each controller has more than one route, and different routes can perform different actions.

Syntax for create controller in Tinh Tinh:

```go
package app

import "github.com/tinh-tinh/tinhtinh/core"

func Controller(module *core.DynamicModule) *core.DynamicController {
    ctrl := module.NewController("users")
    
    ctrl.Get("", func (ctx core.Ctx) {
        ctx.JSON(core.Map{
            "data": "ok"
        })
    })
    
    return ctrl
}
```
