Crucible: A Glue Framework

Crucible is a glue framework based on Flask and includes a number of additional extensions and features found in common use, such as authentication, CSRF protection, and more.

There's a lot to take in that Crucible provides, so the best thing to start with is a list. Crucible:

• provides a more detailed extension system that supports different runtime environments (for running different extension sets)
• includes a wrapper system for unmodified Flask extensions
• exposes default integration with Celery that's relatively easy to use for background task management and offloads long-duration calls like bcrypt() onto Celery out of the box
• includes cryptographic utilities that wrap cryptography.io's primitives and a few high level features
• uses the factory pattern by default for application reuse
• has an extended roster of signals, useful for writing plugins
• integrates primarily with Flask_Classy
• offers additional decorators for use with Flask_Classy
• extensively (ab)uses blueprints
• has an integrated key management with options (eventually) to integrate with KeyStar for centralized key control, rotation, and distribution
• provides an assets pipeline and management with a build tool that integrates with others like webpack
• also includes a "lite" wrapper around SQLAlchemy similar to Flask-SQLAlchemy but without the need to redefine models or worry about potential incompatibilities; use SQLAlchemy as it is!
• supplies integrated Alembic support with motifications to remove the infuriating hash-based naming convention; branches should be managed by your VCS not your migration tool, and migration names should be obvious and communicate clearly in what order they execute
• leans heavily on existing libraries like Click to provide support for custom command line options and even scripts that may be defined in setup.py
• includes a scaffold that can be used to bootstrap new projects with everything needed out of the box

Documentation is currently in the works, including a sample application, so this README is currently little more than a stub. This is because Crucible is not yet ready for general use and may be renamed in the near future to avoid conflicting with projects sharing a similar name.
