# Change Current Theme
|
||
|
|
|
||
|
|
Nebular Theme System provides 3 color schemes out of the box - `default`, `corporate` and `cosmic`. It is both possible to change the theme statically and dynamically during the runtime.
|
||
|
|
|
||
|
|
|
||
|
|
## Switch from Cosmic to Default
|
||
|
|
It is extremely simple to replace a theme from one to another.
|
||
|
|
All you need to do is to find your `NbThemeModule.forRoot` declaration and change a value of the `name` setting:
|
||
|
|
|
||
|
|
```ts
|
||
|
|
@NgModule({
|
||
|
|
imports: [
|
||
|
|
// ...
|
||
|
|
NbThemeModule.forRoot({ name: 'default' }),
|
||
|
|
],
|
||
|
|
}
|
||
|
|
```
|
||
|

|
||
|
|
|
||
|
|
## Runtime Theme Switch
|
||
|
|
In case you want to have a better control when a theme is changed, or for instance need to change it based on a user role,
|
||
|
|
it is possible to dynamically tell Nebular which theme should be enabled.
|
||
|
|
`NbThemeService` is our friend in this case and particularly the `changeTheme` method:
|
||
|
|
|
||
|
|
```ts
|
||
|
|
|
||
|
|
// ...
|
||
|
|
constructor(private themeService: NbThemeService) {
|
||
|
|
this.themeService.changeTheme('corporate');
|
||
|
|
}
|
||
|
|
|
||
|
|
```
|
||
|
|

|
||
|
|
|
||
|
|
## Listen to Theme Change
|
||
|
|
And of course it is possible to subscribe to an event when the current theme gets changed so that you can adjust something in your code accordingly:
|
||
|
|
|
||
|
|
```ts
|
||
|
|
|
||
|
|
// ...
|
||
|
|
constructor(private themeService: NbThemeService) {
|
||
|
|
|
||
|
|
this.themeService.onThemeChange()
|
||
|
|
.subscribe((theme: any) => {
|
||
|
|
console.log(`Theme changed to ${theme.name}`);
|
||
|
|
});
|
||
|
|
}
|
||
|
|
|
||
|
|
```
