Flask bundle
Support for Flask in applauncher
Install: pip install flask_applauncher_bundle
Configuration example
flask:
use_debugger: True
port: {flask_port}
host: {flask_host}
cors: False,
debug: False, # True for internal webserver, False to use with wsgi
secret_key: "cHanGeME"Usage
Flask can load resources by a modular way called Blueprints. Your application only has to provide a blueprint (with your controllers). Lets see how to do this.
from flask import Blueprint, jsonify
import zope.event
import applauncher.kernel
import inject
from flask_bundle import ApiBlueprints
my_blueprint = Blueprint(
'myApp', __name__
)
@my_blueprint.route("/lol", methods=['GET'])
def my_app_get_index():
return jsonify({"foo": "bar"})
# The bundle
class WebBundle(object):
def __init__(self):
# I dont need any configuration so I simply ignore the field config_mapping
# We need to add our blueprint when the dependency injection is ready so
# we need to listen for this event
zope.event.subscribers.append(self.event_listener)
def event_listener(self, event):
if isinstance(event, applauncher.kernel.InjectorReadyEvent):
# When the injection is ready, we fetch the blueprints array
# provided by the FlaskBundle
bp = inject.instance(ApiBlueprints)
bp.append(my_blueprint)
# that's all, later the FlaskBundle will configure this blueprint#WSGI To use with a wsgi server, set the debug option to False (when debug is true, the interal web server of flask is used). Next in your main.py, where the kernel runs, use something like this:
from applauncher.kernel import Environments, Kernel
import flask_bundle
import myapp.bundle
bundle_list = [
flask_bundle.FlaskBundle(),
myapp.bundle.CueBundle(),
]
kernel = Kernel(Environments.DEVELOPMENT, bundle_list, configuration_file="config/config_web.yml")
app = flask_bundle.FlaskBundle.app
And run the uwsgi like this
uwsgi --protocol=uwsgi --processes=2 --threads=1 --socket=0.0.0.0:3031 --module="main:app"
