Custom Storage

The library uses the sessionStorage as the default storage mechanism. If needed, you can create a custom storage implementation, e.g. to use localStorage or cookies. A storage provider is implemented as a class with the AbstractSecurityStorage interface and the read, write and remove methods. The following example shows a custom storage that uses localStorage:

import { AbstractSecurityStorage } from 'angular-auth-oidc-client';

@Injectable()
export class MyStorageService implements AbstractSecurityStorage {
 read(key: string) {
 return localStorage.getItem(key);
 }

 write(key: string, value: any): void {
 localStorage.setItem(key, value);
 }

 remove(key: string): void {
 localStorage.removeItem(key);
 }

 clear(): void {
 localStorage.clear();
 }
}

Then provide the class in the module:

@NgModule({
 imports: [
 AuthModule.forRoot({
 config: {
 // ...
 },
 }),
 ],
 providers: [{ provide: AbstractSecurityStorage, useClass: MyStorageService }],
 exports: [AuthModule],
})
export class AuthConfigModule {}
