CodeIgniter 4.0 is here!

This is great!
I am new to CodeIgniter as have said in my earlier mail and with little things have seen in the CI 3.4 Documentation, I love this framework. I am PHP and MySQL Savvy but I want my work to be faster.
Please, I want anyone of us here to lead me to :
1) Excellent Tutorials or book or Video subscription especially Udemy.com on CodeIgniter4 and Bootstrap 4 or 3.
2) E-commerce website Using CodeIgniter 4 with full admin panel.
I googled and searched but the rating I am seeing confused me. I don't want to have the same experience I had when learning PHP by using about 6 years to look for the book that will add comment to blog when writing blogs all of them were just saying in order to keep the script simple the would not add comment section.
