Walkthrough

The changes in this pull request involve updates to environment variable declarations and configurations related to Google authentication. New variables CALLBACK_URL, PROD_CALLBACK_URL, and NODE_ENV are introduced in the backend/.env.example file. The backend/config/oauth.config.js file is modified to conditionally set the callbackURL based on the NODE_ENV variable. Additionally, the backend/config/secret.js file exports the new environment variables, making them accessible throughout the application.

Changes

File Path Change Summary
backend/.env.example Added CALLBACK_URL, PROD_CALLBACK_URL, and NODE_ENV variables; FRONTEND_URL remains unchanged.
backend/config/oauth.config.js Added console log for config object; updated callbackURL to use NODE_ENV for conditional URL assignment.
backend/config/secret.js Introduced constants for CALLBACK_URL and PROD_CALLBACK_URL from environment variables; updated exports accordingly.

Poem

In the land of code where rabbits play,
New paths are set for a brighter day.
With callbacks ready, both near and far,
We hop along, guided by our star.
Environment's whispers, a sweet, soft tune,
In the garden of code, we'll dance 'neath the moon! 🐇✨

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

🧹 Outside diff range and nitpick comments (5)

8-8: LGTM! Consider adding a comment for clarity.

The CALLBACK_URL is correctly set for local development.

Consider adding a comment to clarify its purpose:

-CALLBACK_URL=http://localhost:3000/auth/google/callback
+CALLBACK_URL=http://localhost:3000/auth/google/callback # Local development callback URL for Google OAuth
backend/config/secret.js (1)

8-9: LGTM! Consider adding comments for clarity.

The addition of CALLBACK_URL and PROD_CALLBACK_URL environment variables is consistent with the existing code style and aligns with the PR objective of configuring environment variables for Google OAuth.

To improve maintainability, consider adding comments explaining the purpose and expected format of these URLs. For example:

// The callback URL for Google OAuth in development environment
const CALLBACK_URL = process.env.CALLBACK_URL;

// The callback URL for Google OAuth in production environment
const PROD_CALLBACK_URL = process.env.PROD_CALLBACK_URL;
backend/config/oauth.config.js (3)

5-5: Consider removing or improving the console log statement.

While console logs can be useful for debugging, they should generally be avoided in production code. If this log is necessary for development or troubleshooting, consider the following improvements:

  1. Add more context to the log message.
  2. Use a logging library that supports log levels.
  3. Ensure it's only executed in non-production environments.

You could replace the current log with:

if (process.env.NODE_ENV !== 'production') {
  console.log('OAuth configuration:', JSON.stringify(config, null, 2));
}

This ensures the log only appears in non-production environments and provides more context and readable output.


12-15: Approve the environment-based callback URL with suggestions for improvement.

The conditional setting of callbackURL based on the environment is a good practice. However, consider the following improvements for increased robustness:

  1. Add a fallback value in case the environment variables are not set.
  2. Consider using a more flexible approach to handle multiple environments.

Here's a suggested improvement:

callbackURL: (() => {
  switch(process.env.NODE_ENV) {
    case 'production':
      return process.env.PROD_CALLBACK_URL;
    case 'staging':
      return process.env.STAGING_CALLBACK_URL;
    case 'development':
    default:
      return process.env.DEV_CALLBACK_URL;
  }
})() || 'http://localhost:3000/auth/google/callback', // Fallback URL

This approach allows for multiple environments and provides a fallback URL if none of the environment variables are set.


Line range hint 1-42: Overall structure is good, but consider some improvements.

The overall structure of the OAuth configuration is solid, with good use of environment variables and error handling. However, consider the following suggestions to enhance the code:

  1. Consolidate configuration sources: The code uses both environment variables and a secret.js file. Consider using a single source of configuration to avoid potential conflicts or confusion.

  2. Enhance error logging: The current error logging in the catch block could be more informative. Consider including more details about the error.

  3. Use TypeScript: If not already using it in the project, consider adopting TypeScript to catch potential type-related issues early in development.

Here's an example of how you might improve the error logging:

catch (error) {
  console.error('Error during Google authentication:', {
    message: error.message,
    stack: error.stack,
    profileId: profile.id
  });
  return done(error, false, { message: "Authentication failed" });
}

This provides more context about the error, which can be crucial for debugging in production environments.
