Intermediate React Tutorial - Todoist Clone (with Firebase, Custom Hooks, SCSS, React Testing)

In this course, we're going to be creating the popular Todoist list application (https://todoist.com) from scratch using React (Custom Hooks, Context), Firebase & React Testing Library (unit & integration testing). In addition to the latter technologies, we will be styling the application using SCSS (CSS) and following the BEM naming methodology. We'll make sure that the application is fully responsive. You will see how to use Lighthouse (Chrome extension) to make sure your website is fully accessible by getting all accessibility features integrated into our application. 💻 Github repo: https://github.com/karlhadwen/todoist (don't forget, you can contribute to this project (highly encouraged!)) 🎥 Video by Karl Hadwen.
