turbo-flask
Integration of Hotwire's Turbo library with Flask, to allow you to create applications that look and feel like single-page apps without using JavaScript.
How to Install
pip install turbo-flask
How to Add to your Project
Direct initialization:
from flask import Flask
from turbo_flask import Turbo
app = Flask(__name__)
turbo = Turbo(app)
Factory function initialization:
from flask import Flask
from turbo_flask import Turbo
turbo = Turbo()
def create_app():
app = Flask(__name__)
turbo.init_app(app)
return app
To add Turbo-Flask to your pages, include {{ turbo() }} in the element of your main Jinja template:
>
<html>
<head>
{{ turbo() }}
head>
<body>
...
body>
html>
How to Use
See the turbo.js documentation to learn how to take advantage of this library.
If you decide to use the Turbo Streams feature, this extension has helper functions to generate the correct Flask responses. Here is an example with a single streamed response:
if turbo.can_stream():
return turbo.stream(
turbo.append(render_template('_todo.html', todo=todo), target='todos'),
)
else:
return render_template('index.html', todos=todos)
And here is another with a list of them:
if turbo.can_stream():
return turbo.stream([
turbo.append(render_template('_todo.html', todo=todo), target='todos'),
turbo.update(render_template('_todo_input.html'), target='form')
])
else:
return render_template('index.html', todos=todos)
WebSocket Streaming
This feature of turbo.js has not been implemented at this time.
