Implement the App with ability to show posts of a current logged-in user. The user should be able to create a new post with their userId. Each post can be opened in the sidebar with its comments, can be edited and deleted. There should delete a comment and a form to add new comments.

Here is the working version

1. Learn the .html files to get all needed layouts;

2. Initially the App shows the Posts table and Create new post button

   • show the <Loader> while waiting for the API response;
   • show an error notification if posts loading fails;
   • if the user has no posts show the No posts yet notification.

3. Add the Sidebar--open class to the sidebar when user click on Create new post;

   • the form for new post should be appear there immediately;
   • add validation to the fields;
   • when user click on Create component with post details and comments should be appear there immediately ;

4. In the Post preview user should see edit and delete buttons;

   • When user click on Delete, post should be deleted and sidebar close;
   • When user click on Edit show edit post form;
   • When user click on Save in edit mode - show post preview in the sidebar;

5. Add the Sidebar--open class to the sidebar when a post is selected;

   • the post details should appear there immediately;
   • the post commnets should be loaded from the API;
   • the Loader is shown before comments are loaded;
   • CommentsError notification is show on loading error;
   • NoComments message is shown if the post does not have comments yet;

6. Show the Write a comment button below the comments

   • after click hide the button and show the form to add new comment;
   • the form stays visible until the other post is opened;
   • the form should be implemented as a separate component;

7. The form requires an author's name and email and a comment text.

   • show errors only after the form is submitted;
   • remove an error on the field change;
   • keep the name and email after the successful submit but clear a comment text;
   • The Clear button should also clear all errors;
   • Add the is-loading class to the submit button while waiting for a response;
   • Add the new comment received as a response from the API to the end of the list;

8. Implement comment deletion

   • Delete the commnet immediately not waiting for the server response to improve the UX.

9. (*) Handle Add and Delete errors so the user can retry
