We’re going to build a Q&A system from scratch starting off with setting up your project using Yeoman and outlining the structure. Along the way we’ll talk about custom elements, material design, routing, authentication, security rules, and record priority. Users will be able to write questions, answers, and comments. Both questions and answers can be upvoted. Using security rules, we’ll make sure that users can only manage their own content within Firebase.
This is an ambitious blog post with a lot of code. If you find an error or aren’t sure how to continue, leave a comment in the post and I’ll make improvements. Walking through this entire series (in progress) could take an hour or two, but by the end you’ll have a thorough understanding of how to build a basic Polymer app.
