I'm currently on hold for my frontend, as I await SvelteKit to be released (I built my other product with Sapper/Svelte and love it, and SvelteKit is the next iteration of Sapper).
As I wait, I've been building out the backends of Producer- Users, Accounts, Organizations, Roles, Projects, Tasks, Comments, Flagging, and more.
I don't normally TDD/test a ton, but as this product is going to have a lot more domain and business logic (especially around subscription levels and roles) I've added a lot more tests than I normally would which, for this application, has been fantastic. (For ListenAddict, they're not really necessary as it's only basic users + me as an admin and fairly simple logic).
Next up, diving into the YouTube APIs!
