I'm new to web development. From looking at popular open-source frameworks for both front-end and back-end, I have a general idea of what the modern full-stack web setup looks like:

Database <-> Back-end language ~ REST API <-> Front-end

Notes:

• The back-end language (Python, Ruby, PHP, Java) generates the API, which is the only layer between the back and the front. The API will have authentication to protect private data.
• The front-end sends GET and POST requests to the API. A MVC framework can be used, such as Backbone, Angular, or Ember.js.

Does this align with best practices for web development?
