Flask built-in features

The previous section gave us a good understanding of how Flask processes a request, and that's good enough to get you started.

But Flask comes with more helpers, which are quite useful. We'll discover the following main ones in this section:

• The session object: Cookie-based data
• Globals: Storing data in the request context
• Signals: Sending and intercepting events
• Extensions and middlewares: Adding features
• Templates: Building text-based content
• Configuring: Grouping your running options in a config file
• Blueprints: Organizing your code in namespaces
• Error handling and debugging: Dealing with errors in your app
