Angular - Routing

You want to lazy load a feature module ProfileModule only when the user navigates to /profile. The module has child routes. Which is the best way to configure the main app routing to achieve this and ensure accessibility and performance?

A{ path: 'profile', loadChildren: () => import('./profile/profile.module').then(m => m.ProfileModule), canActivate: [AuthGuard] }

B{ path: 'profile', component: ProfileModule }

C{ path: 'profile', loadChildren: () => import('./profile/profile.module').then(m => m.ProfileModule) }

D{ path: 'profile', loadChildren: './profile/profile.module#ProfileModule' }

Step-by-Step Solution

Solution:

Step 1: Identify modern lazy loading syntax
The correct syntax uses dynamic import with an arrow function returning a promise: loadChildren: () => import('./profile/profile.module').then(m => m.ProfileModule).
Step 2: Consider best practices for accessibility and performance
For protected features like a user profile, adding canActivate: [AuthGuard] ensures secure access while lazy loading maintains performance.
Step 3: Eliminate incorrect configurations
Using component property fails for modules with child routes. String syntax like './profile/profile.module#ProfileModule' is deprecated.
Final Answer:
{ path: 'profile', loadChildren: () => import('./profile/profile.module').then(m => m.ProfileModule), canActivate: [AuthGuard] } -> Option A
Quick Check:
Lazy load with guard for best practice [OK]

Quick Trick: Lazy load with import and add guards for security [OK]

Common Mistakes:

MISTAKES

Using component instead of loadChildren for modules
Using deprecated string syntax
Forgetting route guards for protected routes
