performing resolver when needed in angular version 5

I have been working on a project using Angular and recently updated it from version 4.2 to Angular 5. Although I haven't utilized any new features introduced in Angular 5 yet.

My current task involves executing a resolver on a specific route when a certain condition is met within the code. Here's an example:

if (a === b) {
     //execute resolver
}

I am uncertain about the correct approach for accomplishing this, as a resolver is essentially a TypeScript class just like any other.

Answer №1

I thought I'd give it a try. Without seeing any actual code, here's a generalization. Earlier this year, I used a simple ternary operation to accomplish a task.

Within app.module.ts provider section of Resolver

  {
        provide: 'conditionResolver', useValue: (route: ActivatedRouteSnapshot, state: RouterStateSnapshot) => {
            //Here is a sample implementation
            window.open((route.data as any).otherUrl);
        }
    }

In the app.router.ts route section of Implementation

    path: 'SomeComponentURL', component: SomeComponent, resolve: {
        url: 'conditionResolver'
    },
    data: {
        condition: (someCondition != '#/SomeComponent')
            ? 'doSomething()' : orDoSomethingElse()
    }

Answer №2

In the end, I found a solution by making adjustments to my route configuration and adding a condition directly into the resolver's resolve method.
