Angular pass resolve data to child-routes

You just need to do this in child components:

ngOnInit() {
    this.route.parent.data
        .subscribe((data) => {
            this.edit = data.edit;
        });
}

You have two options here:

1. You can access parent resolve data via the child's resolver by creating a child-specific resolver and accessing the route's parent property.

[...module.ts | ...component.ts]

{
    path: 'project/:projectId', 
    component: ProjectDetailComponent,
    resolve: { project: ProjectResolver }
    children: [
        { 
            path: ':projectId/edit',
            component: EditProjectComponent,
            resolve: { edit: EditProjectResolve }
        }
    ]
}

edit-project-component.ts

ngOnInit() {
    this.edit = this.route.snapshot.data.edit;
}

2. You can bypass the child's resolver all together and access parent data from within the child component.

[...module.ts | ...component.ts]

{
    path: 'project/:projectId', 
    component: ProjectDetailComponent,
    resolve: { project: ProjectResolver }
    children: [
        { 
            path: ':projectId/edit',
            component: EditProjectComponent
        }
    ]
}

edit-project-component.ts

ngOnInit() {
    this.route.parent.data
        .subscribe((data) => {
            this.edit = data.edit;
        });
}
