How to use the extension
Install
To install this extension as a requirement in your project, you can use PIP:
pip install canonicalwebteam.flask-vite
Configure
The extension parses the following values from the Flask app.config object:
VITE_MODE: "development" | "production"- type of environment in which the Vite integration will runVITE_PORT: int- port where Vite's dev server is runningVITE_OUTDIR: str- file system path where the Vite output is expected; the path can be absolute or relative to the Flask app's root directory
Import
The extension adds a new template global function named vite_import. To include a script or stylesheet, simply invoke this template function passing the path to the file you want to import, relative to the app's root directory.
Example
To import a script whose path is < flask app directory >/js/app/main.ts:
{ vite_import("js/app/main.ts") }
Note: all files imported via
vite_importmust be declared as entry points in your Vite config; if this isn't the case, the Vite build command will not process the file you're trying to import, so the extension will NOT work in production mode.
Minimal usage example
# app.py
app = Flask()
app.config["VITE_MODE"] = "development" if app.debug else "production"
app.config["VITE_PORT"] = 9999
app.config["VITE_OUTDIR"] = "static/dist"
vite = FlaskVite()
vite.init_app(app)
# ...
<!-- templates/base.html -->
<head>
{ vite_import("path/to/source/styles.scss") }
</head>
<body>
<!-- ... -->
{ vite_import("path/to/source/file.tsx") }
</body>
