‘Shared Module is Not Available for Eager Consumption’ Error in Angular

The error message “shared module is not available for eager consumption” in Angular typically occurs when there’s an issue with how you are importing or exporting modules within your Angular application. This error is often associated with lazy loading in Angular, where certain modules are intended to be loaded lazily, but there’s a misconfiguration.

Here are some steps you can take to troubleshoot and resolve this issue:

• Check Module Imports: Ensure that you are importing and exporting modules correctly. If you have circular dependencies or if a module is not being imported where it’s needed, it can result in this error.
• Lazy Loading Configuration: If you are using lazy loading, verify that the modules you are lazy loading are configured correctly in your routing module. Ensure that you are using the loadChildren property correctly.

// Example lazy loading configuration in app-routing.module.ts
const routes: Routes = [
  {
    path: 'lazy',
    loadChildren: () => import('./lazy/lazy.module').then(m => m.LazyModule)
  }
];

• Check Module Providers: Ensure that services or components from the “shared module” are being provided correctly. If you have services or components that are part of a shared module, they need to be provided in the correct module or in the AppModule if they are meant to be application-wide.
• Angular Version Compatibility: Check if there’s any compatibility issue between your Angular version and the version of third-party libraries or modules you are using. Ensure that you are using compatible versions.
• Inspect Angular CLI Configuration: Review your angular.json file for any misconfigurations related to modules or lazy loading. Ensure that the paths and configurations are accurate.
• Circular Dependencies: Be cautious of circular dependencies between modules. Angular does not support circular dependencies, and this can lead to unexpected behavior.
• Rebuild and Restart: After making changes, rebuild your application and restart the development server to ensure that the changes take effect.
• Check for Typos: Ensure that there are no typos or case-sensitive mismatches in your module names or import statements.

Circular dependencies, improper lazy loading configurations, and inaccuracies in the Angular CLI setup are frequent culprits behind Shared Module Not Eagerly Consumable error. By addressing these common causes, you get the way for a more better and error-free Angular application.

By systematically reviewing your module imports, lazy loading configurations, and provider settings, you should be able to identify and resolve the issue causing the “shared module is not available for eager consumption” error in your Angular application.
