The configuration here refers to the configuration information of the plugin. In general, the plugin needs to obtain the configuration of the web application. In the first case, the python module of the plugin needs configuration information, and the second case is that the template code of the plugin needs to obtain configuration information.

In the first case, the plugin can be imported directly into the configuration file module, or use current_app.config.

In the second case, the Flask itself already supports the configuration of current_app.config directly in the template using config, but the old version (before 0.10) may not support it, so Flask-PluginKit adds a template “global variable”, emit_config(), the configuration passed to PluginManager with the pluginkit_config parameter and the configuration of current_app.config can be obtained directly.


The emit_config will first look in the pluginkit_config parameter. If not found, then find current_app.config. If still can’t find, return None.

from flask_pluginkit import PluginManager
PluginManager(app, pluginkit_config=dict(HELLO="WORLD"))
  • Plugin call

Suppose the following code is a template file under a plugin, get HELLO and DEBUG configuration:

    Hello: {{ emit_config("HELLO") }}
    App is debug: {{ emit_config("DEBUG") }}
