Pros of oidc-client-js

• Framework-agnostic, can be used with any JavaScript application
• More mature and widely adopted in the community
• Extensive documentation and examples available

Cons of oidc-client-js

• Less Angular-specific features and integration
• May require more manual configuration for Angular projects
• Not actively maintained (last update was in 2021)

Code Comparison

oidc-client-js:

var settings = {
    authority: 'https://demo.identityserver.io/',
    client_id: 'implicit',
    redirect_uri: 'https://localhost:5000/callback.html',
    response_type: 'id_token token',
    scope: 'openid profile email api',
};
var mgr = new Oidc.UserManager(settings);

angular-auth-oidc-client:

@NgModule({
    imports: [
        AuthModule.forRoot({
            config: {
                authority: 'https://demo.identityserver.io',
                redirectUrl: window.location.origin,
                clientId: 'angular',
                scope: 'openid profile email api',
            },
        }),
    ],
})
export class AppModule {}

The code snippets demonstrate the configuration differences between the two libraries. oidc-client-js uses a more generic JavaScript approach, while angular-auth-oidc-client is specifically designed for Angular applications, offering a more integrated and type-safe configuration within the Angular module system.

Pros of angular-oauth2-oidc

• More comprehensive documentation and examples
• Support for multiple OAuth 2.0 flows, including implicit and code flow
• Active community with frequent updates and contributions

Cons of angular-oauth2-oidc

• Slightly more complex setup process
• May have a steeper learning curve for beginners
• Some users report occasional issues with token refresh

Code Comparison

angular-oauth2-oidc:

import { AuthConfig } from 'angular-oauth2-oidc';

export const authConfig: AuthConfig = {
  issuer: 'https://idsvr4.azurewebsites.net',
  redirectUri: window.location.origin + '/index.html',
  clientId: 'spa',
  scope: 'openid profile email api',
};

angular-auth-oidc-client:

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

export const config: OpenIdConfiguration = {
  authority: 'https://idsvr4.azurewebsites.net',
  redirectUrl: window.location.origin,
  clientId: 'spa',
  scope: 'openid profile email api',
};

Both libraries offer similar functionality for implementing OAuth 2.0 and OpenID Connect in Angular applications. angular-oauth2-oidc provides more extensive documentation and supports multiple OAuth flows, making it suitable for complex scenarios. However, it may be slightly more challenging to set up initially. angular-auth-oidc-client offers a simpler setup process and may be more suitable for beginners or straightforward authentication requirements. The code comparison shows that both libraries use similar configuration objects, with minor differences in property names.

Pros of oidc-client-ts

• Framework-agnostic, can be used with any JavaScript framework
• Smaller bundle size, focused solely on OIDC functionality
• More active development and frequent updates

Cons of oidc-client-ts

• Less Angular-specific features and integrations
• May require more manual configuration for Angular projects
• Fewer built-in guards and interceptors for Angular routing

Code Comparison

oidc-client-ts:

import { UserManager } from "oidc-client-ts";

const userManager = new UserManager(settings);
const user = await userManager.signinRedirect();

angular-auth-oidc-client:

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

constructor(public oidcSecurityService: OidcSecurityService) {}
this.oidcSecurityService.authorize();

The oidc-client-ts library provides a more generic approach, while angular-auth-oidc-client offers Angular-specific implementations. oidc-client-ts requires manual instantiation of the UserManager, whereas angular-auth-oidc-client integrates more seamlessly with Angular's dependency injection system.

Both libraries serve the purpose of implementing OpenID Connect authentication, but they cater to different use cases. oidc-client-ts is more versatile for various JavaScript projects, while angular-auth-oidc-client is tailored specifically for Angular applications, providing a more integrated experience within the Angular ecosystem.

Pros of openid-client

• Language-agnostic: Can be used with various programming languages and frameworks
• More comprehensive OpenID Connect support, including advanced features
• Actively maintained with frequent updates and improvements

Cons of openid-client

• Steeper learning curve due to its broader scope and flexibility
• Less Angular-specific optimizations and integrations
• May require additional configuration for Angular projects

Code Comparison

angular-auth-oidc-client:

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

@NgModule({
  imports: [AuthModule.forRoot({
    config: { authority: 'https://example.com', clientId: 'client' }
  })]
})
export class AppModule {}

openid-client:

const { Issuer } = require('openid-client');

Issuer.discover('https://example.com')
  .then(issuer => {
    const client = new issuer.Client({
      client_id: 'client',
      client_secret: 'secret'
    });
  });

The angular-auth-oidc-client example shows a more Angular-specific implementation, while openid-client demonstrates a more generic approach that can be adapted to various environments. The openid-client example requires additional setup for Angular integration, but offers more flexibility for different use cases.
