A huge, ongoing project.
I'd love to build a web app with Twitter functionality, and this is one of the larger tutorial projects I have worked on, with currently over twelve hours of coding, and nearly five hours of pure instruction completed. The project can really be split into two separate sections, the first being a backend MongoDB server using Apollo and GraphQL:
The second part of the project is a React frontend styled by SemanticUI.
The project is still being worked on. At the moment users can login, post and like tweets.
