Project 4 for CS50’s Web Programming with Python and JavaScript.

A design of Twitter-like social network website for making posts and following users.

This project fulfills the following requirements:

• New Post: Users who are signed in will be able to write a new text-based post by filling in text into a text area and then clicking a button to submit the post.
  • The screenshot at the top of this specification shows the “New Post” box at the top of the “All Posts” page.
• All Posts: The “All Posts” link in the navigation bar takes the user to a page where they can see all posts from all users, with the most recent posts first.
  • Each post includes the username of the poster, the post content itself, the date and time at which the post was made, and the number of “likes” the post has.
• Profile Page: Clicking on a username loads that user’s profile page. This page:
  • Displays the number of followers the user has, as well as the number of people that the user follows.
  • Displays all the posts for that user, in reverse chronological order.
  • For any other user who is signed in, this page also displays a “Follow” or “Unfollow” button that will let the current user toggle whether they are following this user’s posts. Notice that this only applies to any “other” user: a user can not be able to follow themselves.
• Following: The “Following” link in the navigation bar takes the user to a page where they see all posts made by users that the current user follows.
  • This page behaves just as the “All Posts” page does, just with a more limited set of posts.
  • This page is only be available to users who are signed in.
• Pagination: On any page that displays posts, posts are only displayed 10 on a page. If there are more than ten posts, a “Next” button is appeared to take the user to the next page of posts (which is older than the current page of posts). If not on the first page, a “Previous” button appears to take the user to the previous page of posts as well.
• Edit Post: Users are able to click an “Edit” button or link on any of their own posts to edit that post.
  • When a user clicks “Edit” for one of their own posts, the content of their post should be replaced with a textarea where the user can edit the content of their post.
  • The user should then be able to “Save” the edited post, without reloading the page, using JavaScript.
  • For security, this application is designed such that it is not possible for a user, via any route, to edit another user’s posts.
• “Like” and “Unlike”: Users are able to click a button or link on any post to toggle whether they “like” that post.
  • Using JavaScript, asynchronously I let the server know to update the like count (as via a call to fetch) and then update the post’s like count displayed on the page, without requiring a reload of the entire page.
