Example 2 from flask-base

flask-base (project documentation) provides boilerplate code for new Flask web apps. The purpose of the boilerplate is to stitch together disparate libraries that are commonly used in Flask projects, such as Redis for fast caching and transient data storage, SendGrid for transactional email, SQLAlchemy for persistent data storage through a relational database backend, Flask-WTF for form handling and many others.

Example 4 from Flask-Security-Too

Flask-Security-Too (PyPi page and project documentation) is a maintained fork of the original Flask-Security project that makes it easier to add common security features to Flask web applications. A few of the critical goals of the Flask-Security-Too project are ensuring JavaScript client-based single-page applications (SPAs) can work securely with Flask-based backends and that guidance by the OWASP organization is followed by default.
