Changes 4/3/25

Spring Cleaning

• Updated packages: Upgraded all dependencies to their latest versions for compatibility and improved functionality.
• Logout function: Refactored the logout function in auth.js to include a callback for req.logout (required in Passport v0.6.0+). Ensured the session is properly destroyed using req.session.destroy, the session cookie is cleared with res.clearCookie("connect.sid"), and the user is redirected to the homepage (/).
• Deleting posts: Replaced the deprecated Post.remove method with Post.findByIdAndDelete in posts.js for compatibility with Mongoose v7.x. Simplified Post.findById by removing unnecessary curly braces and _id to streamline the query.
• Comment creation: Fixed the comment creation functionality by correcting the res.redirect URL in comments.js to include the missing / between /post and the post ID, ensuring proper redirection back to the post page.
• Passport.js refactor: Refactored passport.js to replace callback-based Mongoose queries (e.g., User.findOne) with async/await for compatibility with Mongoose v7.x, which no longer supports callbacks. Improved error handling by wrapping queries in try/catch blocks for better reliability and debugging.

Added Comment functionality to the Social Media site

• Added a like button for comments:

• Updated the comments.js route file to include a PUT route for liking comments (/likeComment/:id).

• Added a likeComment method in the commentsController to increment the likes field in the Comment model using findByIdAndUpdate.

• Updated the post.ejs file to include a like button for each comment, which sends a PUT request to the server using the method-override middleware.

• Added a delete button for comments:

• Updated the comments.js route file to include a DELETE route for deleting comments (/deleteComment/:id).

• Added a deleteComment method in the commentsController to find and delete a comment by its ID using findById and deleteOne.

• Updated the post.ejs file to include a delete button for each comment, which sends a DELETE request to the server using the method-override middleware.

• Ensured the postId is passed as a hidden input in the form to allow redirection back to the correct post page after deletion.

• Updated deleting comments when deleting posts:

• deleteMany() is a mongoDB method that is used to delete multiple documents from a collection that match a specified filter. This allows for easy removal of comments when getting rid of a post.

• Added some CSS to make comments nicer to look at.
