Transport Vite apps.

Project description

🚚 vite-transporter

Transport Vite apps.

pip install vite-transporter

Currently compatible with:

  • Flask
  • Quart

Note (Flask/Quart): When including credentials in fetch requests in the vite app. You must visit the serve app first to set the credentials.

For example, if the serve app is running on http://127.0.0.1:5001, you must visit this address first.

This won't be needed in production, as it's expected that the Vite app will be served from the same domain.

How it works

The pyproject.toml file

The pyproject.toml file is used to store what Vite apps are available.

Adding the following to the pyproject.toml file will transfer all the Vite apps listed in the vite_app_dirs list to the serving app listed in the serve_app key.

pyproject.toml:

[tool.vite_transporter]
npm_exec = "npm"
npx_exec = "npx"
serve_app = "app_flask_demo"
vite_apps = ["app_vite_demo"]

The compiling of the Vite apps requires the npx and npm to be available. You can use absolute paths here.

npm_exec is used to run npm install if your Vite app does not have the node_modules folder.

npx is used to run the Vite app build command.

serve_app is the app that will serve the Vite compiled files.

vite_app_dirs is a list of directories that contain Vite apps.

You can send over many Vite apps to the serving app, they will be accessible within template files.

List the Vite apps

You can see what apps can be compiled by running:

vt list

Compiling the Vite apps

vt compile

The Vite apps are compiled into a dist folder, the files contained in this folder are then moved to a folder called vt in the serving app.

Any js file that is compiled that contains an asset reference will replace assets/ with /__vt/{app_name}.

Working with vite-transporter using Flask / Quart

vite-transporter creates a couple of Flask / Quart context processors that match the Vite apps to a Flask / Quart template.

The context processors

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    {{ vt_head('app_vite_demo') }}
    <title>Test</title>
</head>
<body>
{{ vt_body() }}
</body>
</html>
vt_head(
    vite_app_name: str  # The name of the Vite app to load
)
vt_body(
    root_id: str = "root",  # The id of the root element
    noscript_message: str = "You need to enable JavaScript to run this app.",
)

Flask Example

from flask import Flask, render_template

from vite_transporter.platform.flask import ViteTransporter


def create_app():
    app = Flask(__name__)
    ViteTransporter(app)

    @app.route("/")
    def index():
        return render_template("index.html")

    return app

Quart Example

from quart import Quart, render_template

from vite_transporter.platform.quart import ViteTransporter


def create_app():
    app = Quart(__name__)
    ViteTransporter(app)

    @app.route("/")
    async def index():
        return await render_template("index.html")

    return app

CORS

Setting:

ViteTransporter(app, cors_allowed_hosts=["http://127.0.0.1:5003"])

This is to allow the Vite app to communicate with the app.

Note: It's recommended to remove this in production.

Running the demos

We will be using a package call pyqwe to run commands from the pyproject file. Installing the development requirements will install pyqwe:

pip install -r requirements/development.txt

Use pyqwe to install the local version of vite-transporter:

pyqwe install

serve_app is currently set to use the Flask demo app.

We will run this in terminal 1:

pyqwe flask

Next, we will run the Vite app in terminal 2:

pyqwe vite

Visit the vite app from the link in the terminal. Change something, save, then in terminal 3 run:

vt compile

The Vite app will be compiled, and the files will be moved to the Flask app. Visiting the Flask app from the link in terminal 1 should show the changes.
