Use global container for Dependency injection

[jorgebenzeno]

It should be interesting to use a container for dependency injection
Because if somone like me wants to extends the resolver using a different database we need to rewrite the whole code

even for test it's better for injecting memory database is needed or some mocks

What's do you think ?

app.py

from flask import Flask, jsonify
from flask_injector import FlaskInjector
from injector import inject, Binder
from services import DatabaseService, UserService

app = Flask(name)

Configure bindings

def configure(binder: Binder):
binder.bind(DatabaseService, to=DatabaseService, scope=singleton)
binder.bind(UserService, to=UserService, scope=singleton)

Inject dependencies into routes

@app.route('/user')
@Inject
def get_user(user_service: UserService):
return jsonify(user=user_service.get_user())

Setup FlaskInjector

FlaskInjector(app=app, modules=[configure])

if name == 'main':
app.run()
