Blueprint Extension Point


The extension point abbreviation is bep.

This extension point is very simple, just add a blueprint to the web application, no different from the normal blueprint.

The plugin needs to return the bep field via register. The bep data type returned is a dictionary with the format {blueprint: Blueprint Instance, prefix: /your_blueprint_url_prefix, parent: Name}. Only one blueprint is currently supported.

Changed in version 3.6.2: Support Flask2.0 nested blueprint with the parent param(beta). But only blueprints of other plugins can be nested.

The Flask-PluginKit loads bep via _bep_handler(), this method will detect bep rules and specific content.

The blueprint can be mounted under None or under other prefixes. Flask-PluginKit does not detect blueprint routing, as long as the prefix is legal.

The user only needs to ensure that the plugin is harmless and does not pollute your original application. Others are plugin developers.

If you just want to add the view to the existing blueprint, you can refer to vep on blueprint
