# Lifecylce Hook: onModeExit
|
||
|
|
|
||
|
|
If an extension defines the `onModeExit` lifecycle hook, it is called when navigating
|
||
|
|
away from a mode. This hook can be used to clean up data tasks such as unregistering services,
|
||
|
|
removing annotations that do not need to be persisted.
|
||
|
|
|
||
|
|
_Example `onModeExit` hook implementation_
|
||
|
|
|
||
|
|
```js
|
||
|
|
export default {
|
||
|
|
id: 'myExampleExtension',
|
||
|
|
|
||
|
|
onModeExit({ servicesManager, commandsManager}) {
|
||
|
|
myCacheServie.purge()
|
||
|
|
},
|
||
|
|
};
|
||
|
|
```
