Pros of openid-client

• More comprehensive OpenID Connect support, including advanced features like JWT-secured authorization
• Better TypeScript support with full type definitions
• More active development and frequent updates

Cons of openid-client

• Steeper learning curve due to its more extensive API
• Less browser-specific optimizations compared to oidc-client-js
• Requires more setup and configuration for basic use cases

Code Comparison

oidc-client-js:

const 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'
};
const userManager = new Oidc.UserManager(settings);

openid-client:

const client = await Issuer.discover('https://demo.identityserver.io')
  .then(issuer => new issuer.Client({
    client_id: 'implicit',
    redirect_uris: ['https://localhost:5000/callback.html'],
    response_types: ['id_token token'],
  }));

Both libraries provide robust OpenID Connect implementations, but openid-client offers more advanced features and better TypeScript support at the cost of increased complexity. oidc-client-js may be more suitable for simpler use cases and browser-specific optimizations.

Pros of oidc-client-ts

• Written in TypeScript, providing better type safety and developer experience
• More actively maintained with regular updates and bug fixes
• Improved performance and smaller bundle size

Cons of oidc-client-ts

• Potential breaking changes when migrating from oidc-client-js
• May require additional configuration for TypeScript projects

Code Comparison

oidc-client-js:

import { UserManager } from 'oidc-client';

const userManager = new UserManager({
  authority: 'https://example.com',
  client_id: 'client_id',
  redirect_uri: 'https://app.example.com/callback'
});

oidc-client-ts:

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

const userManager = new UserManager({
  authority: 'https://example.com',
  client_id: 'client_id',
  redirect_uri: 'https://app.example.com/callback'
});

The code usage is similar between the two libraries, with the main difference being the import statement. oidc-client-ts uses the 'oidc-client-ts' package instead of 'oidc-client'.

Both libraries provide similar functionality for implementing OpenID Connect and OAuth2 in JavaScript applications. oidc-client-ts is essentially a TypeScript rewrite of oidc-client-js, offering improved type safety and maintenance. While the migration might require some adjustments, the benefits of using oidc-client-ts, especially in TypeScript projects, often outweigh the initial setup costs.

Pros of angular-auth-oidc-client

• Specifically designed for Angular applications, providing seamless integration
• Offers more Angular-specific features and optimizations
• Actively maintained with frequent updates and community support

Cons of angular-auth-oidc-client

• Limited to Angular framework, less versatile for other JavaScript applications
• May have a steeper learning curve for developers not familiar with Angular

Code Comparison

oidc-client-js:

var settings = {
  authority: 'https://demo.identityserver.io/',
  client_id: 'js',
  redirect_uri: 'https://myapp.com/callback.html',
  response_type: 'code',
  scope: 'openid profile 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 offline_access',
        responseType: 'code',
      },
    }),
  ],
})
export class AppModule {}

The code examples show the configuration setup for both libraries. oidc-client-js uses a more generic JavaScript approach, while angular-auth-oidc-client integrates directly with Angular's module system, demonstrating its framework-specific design.
