|

|
| 16 | * if a component can be instantiated as part of a navigation.
|
| 17 | *
|
| 18 | * <aside class="is-right">
|
| 19 | * Note that unlike other lifecycle hooks, this one uses an annotation rather than an interface.
|
| 20 | * This is because the `CanActivate` function is called before the component is instantiated.
|
| 21 | * </aside>
|
| 22 | *
|
| 23 | * The `CanActivate` hook is called with two {@link ComponentInstruction}s as parameters, the first
|
| 24 | * representing the current route being navigated to, and the second parameter representing the
|
| 25 | * previous route or `null`.
|
| 26 | *
|
| 27 | * ```typescript
|
| 28 | * @CanActivate((next, prev) => boolean | Promise<boolean>)
|
| 29 | * ```
|
| 30 | *
|
| 31 | * If `CanActivate` returns or resolves to `false`, the navigation is cancelled.
|
| 32 | * If `CanActivate` throws or rejects, the navigation is also cancelled.
|
| 33 | * If `CanActivate` returns or resolves to `true`, navigation continues, the component is
|
| 34 | * instantiated, and the {@link OnActivate} hook of that component is called if implemented.
|
| 35 | *
|
| 36 | * ### Example
|
| 37 | *
|
| 38 | * {@example router/ts/can_activate/can_activate_example.ts region='canActivate' }
