Build A SaaS App in Rails 6
Build A SaaS App in Rails 6
About the Book
Building an application to provide business is tough. It's overwhelming. There are so many choices! What gems do you use? How do you manage users? What if there was a step-by-step guide to feed you those answers?
This book will guide you from your very first rails commands, through integrating Stripe, background jobs and finally deploying your app to a cloud provider. You'll be mastering a SaaS application, getting customers and monetizing your expertise in no time!
Worried the material won't help you build a complex application? I am currently running Mail Buffer and Pull Manager using the very same code and techniques from the book.
