The Angular code does not work when used within a custom library

If you are facing issues with Angular code not working when used within a custom library, you are not alone. This is a common problem that many developers face when trying to integrate Angular code into a custom library. However, there are a few solutions that you can try to resolve this issue.

Solution 1: Exporting Angular Modules

One possible reason why your Angular code is not working within a custom library is because the required Angular modules are not being exported correctly. To fix this, you need to ensure that all the necessary modules are exported from your library.

Here’s an example of how you can export Angular modules from your custom library:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { MyComponent } from './my-component/my-component.component';

@NgModule({
  declarations: [MyComponent],
  imports: [CommonModule],
  exports: [MyComponent] // Exporting the component
})
export class MyLibraryModule { }

Make sure to export all the required modules and components from your library. This will allow you to use them in your Angular application.

Solution 2: Importing the Library Module

Another reason why your Angular code might not be working within a custom library is because you are not importing the library module correctly in your Angular application. To fix this, you need to ensure that you are importing the library module in your application’s module file.

Here’s an example of how you can import the library module in your Angular application:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MyLibraryModule } from 'my-library';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, MyLibraryModule], // Importing the library module
  bootstrap: [AppComponent]
})
export class AppModule { }

Make sure to import the library module in the imports array of your application’s module file. This will ensure that the required modules and components from your library are available in your Angular application.

Solution 3: Checking Angular Version Compatibility

It’s also possible that the Angular version used in your custom library is not compatible with the Angular version used in your application. This can lead to compatibility issues and cause your Angular code to not work properly.

Make sure to check the Angular version compatibility between your library and application. Ensure that both are using the same or compatible versions of Angular. You can check the Angular version in the package.json file of your library and application.

If there is a version mismatch, you might need to update either your library or application to ensure compatibility.

By following these solutions, you should be able to resolve the issue of Angular code not working within a custom library. Remember to export the required modules, import the library module correctly, and check for Angular version compatibility.

Happy coding!
