An extension to add support of Plugin in Flask.

Features:

  1. Define plugin routes in the same way as Application, Blueprint, while providing all the Flask features (Template rendering, url_for, message flashing, signals, etc.)
  2. Each plugin can be started, stopped, reloaded while Flask is running.
  3. Configured with Flask, no need to configure separately.
  4. Auto-discovery and management for plugins.

Install

Download from git repo and install:

git clone https://github.com/guiqiqi/flask-plugin
python3 flask-plugin/setup.py install

Quick start

  1. Entering the example directory, you will find the following directory structure, the plugin hello inside plugins directory:

    example
├── app.py
└── plugins
    └── hello
        ├── __init__.py
        ├── static
        │   └── test.txt
        └── templates
            └── index.html

  2. The plugin manager is loaded in the app.py file, and the hello plugin is started:

    from flask import Flask
from flask_plugin import Manager

app = Flask(__name__)
manager = Manager(app)
plugin = manager.find(id_='347336b4fcdd447985aec57f2bc5793c')
if plugin:
    manager.load(plugin)
    manager.start(plugin)

...
# API Management code here
app.run()

  3. Instantiated the Plugin in SayHello/__init__.py and define the route as you did in Flask:

    from flask_plugin import Plugin
from flask import redirect, url_for

plugin = Plugin(
 id_ = '347336b4fcdd447985aec57f2bc5793c', 
 domain='hello', name='Greeting',
 static_folder='static',
 template_folder='templates'
)

...
# Other routes defined here

@plugin.route('/', methods=['GET'])
def index():
    return render_template('index.html', name='Anonymous')

  4. Accessing /plugins/hello/ and see the greeting:

    Hello Anonymous!

    Stop the plugin with accessing /api/stop/347336b4fcdd447985aec57f2bc5793c, check url above again, and get a HTTP 404 error.
