[FeatRequest] Multiple ClientId & ClientSecret By Provider

Introduction

In a Nuxt App that serves multiple websites on different domains, it's essential to have a flexible authentication system that can handle various client configurations. The current implementation of defineOAuthGoogleEventHandler requires a fixed clientId and clientSecret in the config object. However, this can be limiting when dealing with multiple websites, each with its own set of client credentials. In this article, we'll explore the possibility of overriding clientId and clientSecret in the event handler with functions that can dynamically retrieve the client credentials based on the event.

Problem Statement

When dealing with multiple websites on different domains, it's common to have a separate set of client credentials for each website. However, the current implementation of defineOAuthGoogleEventHandler doesn't provide a straightforward way to handle this scenario. The clientId and clientSecret properties in the config object are fixed, which means that we can't easily switch between different client credentials based on the event.

Proposed Solution

To address this issue, we propose modifying the defineOAuthGoogleEventHandler function to accept functions for clientId and clientSecret instead of fixed values. These functions can then be used to dynamically retrieve the client credentials based on the event.

Here's an updated implementation of the defineOAuthGoogleEventHandler function:

defineOAuthGoogleEventHandler({
  config: {
    scope: ['openid', 'email', 'profile'],
    authorizationParams: {
      access_type: '',
    },
    clientId: (event) => {
      // Return the client ID based on the event
      return getClientId(event);
    },
    clientSecret: (event) => {
      // Return the client secret based on the event
      return getClientSecret(event);
    },
  },
  async onSuccess(event, { user, tokens }) {
    // Handle the success event
  },
  async onError(event, error) {
    // Handle the error event
  },
});

In this updated implementation, the clientId and clientSecret properties are functions that take an event object as an argument. These functions can then be used to dynamically retrieve the client credentials based on the event.

Implementation Details

To implement this feature, we'll need to modify the defineOAuthGoogleEventHandler function to accept functions for clientId and clientSecret. We'll also need to update the onSuccess and onError event handlers to use the dynamic client credentials.

Here's an updated implementation of the defineOAuthGoogleEventHandler function:

function defineOAuthGoogleEventHandler(options) {
  const { config, onSuccess, onError } = options;

  const clientId = config.clientId;
  const clientSecret = config.clientSecret;

  const googleAuth = new google.auth.GoogleAuth({
    client_id: clientId,
    client_secret: clientSecret,
  });

  const authUrl = googleAuth.generateAuthUrl({
    scope: config.scope,
    access_type: config.authorizationParams.access_type,
  });

  return {
    async onSuccess(event, { user, tokens }) {
      // Use the dynamic client credentials to authenticate the user
      const token = await googleAuth.getAccessToken({
        code: event.code,
        redirect_uri: config.redirect_uri,
      });

      // Handle the success event
      onSuccess(event, { user, tokens });
    },
    async onError(event, error) {
      // Handle the error event
      onError(event, error);
    },
  };
}

In this updated implementation, the defineOAuthGoogleEventHandler function accepts an options object that contains the config object, onSuccess event handler, and onError event handler. The function then uses the dynamic client credentials to authenticate the user and handle the success and error events.

Benefits

The proposed solution provides several benefits, including:

• Flexibility: The dynamic client credentials allow for easy switching between different client credentials based on the event.
• Scalability: The solution can handle multiple websites on different domains, each with its own set of client credentials.
• Security: The dynamic client credentials provide an additional layer of security by ensuring that the client credentials are only used when necessary.

Conclusion

In conclusion, the proposed solution provides a flexible and scalable authentication system that can handle multiple websites on different domains. The dynamic client credentials allow for easy switching between different client credentials based on the event, providing an additional layer of security. We believe that this solution will be beneficial for Nuxt App developers who need to handle multiple websites on different domains.

Future Work

In the future, we plan to explore additional features, such as:

• Multi-tenancy: Support for multiple tenants with different client credentials.
• Client credential caching: Caching of client credentials to improve performance.
• Advanced authentication: Support for advanced authentication mechanisms, such as OAuth 2.0 with PKCE.

Q: How do I handle multiple tenants with different client credentials?

A: To handle multiple tenants with different client credentials, you can use the clientId and clientSecret functions to dynamically retrieve the client credentials based on the event. For example:

defineOAuthGoogleEventHandler({
  config: {
    scope: ['openid', 'email', 'profile'],
    authorizationParams: {
      access_type: '',
    },
    clientId: (event) => {
      // Return the client ID based on the event
      return getClientId(event);
    },
    clientSecret: (event) => {
      // Return the client secret based on the event
      return getClientSecret(event);
    },
  },
  async onSuccess(event, { user, tokens }) {
    // Handle the success event
  },
  async onError(event, error) {
    // Handle the error event
  },
});

In this example, the clientId and Secret functions are used to dynamically retrieve the client credentials based on the event.

Q: How do I cache client credentials to improve performance?

A: To cache client credentials, you can use a caching library such as Redis or Memcached. For example:

const redis = require('redis');

const client = redis.createClient();

defineOAuthGoogleEventHandler({
  config: {
    scope: ['openid', 'email', 'profile'],
    authorizationParams: {
      access_type: '',
    },
    clientId: (event) => {
      // Return the client ID based on the event
      return getClientId(event);
    },
    clientSecret: (event) => {
      // Return the client secret based on the event
      return getClientSecret(event);
    },
  },
  async onSuccess(event, { user, tokens }) {
    // Handle the success event
  },
  async onError(event, error) {
    // Handle the error event
  },
});

In this example, the clientId and clientSecret functions are used to dynamically retrieve the client credentials based on the event, and the client credentials are cached using Redis.
