Readme
Flask-Bundler allows you to serve your project assets from Webpack directly, allowing cache busting and easy deployment.
It uses Webpack's BundleTracker plugin to get information about the bundles in your configuration and to serve them.
You need to configure Webpack to output webpack-stats.json
. For this, add
webpack-bundle-tracker
as a Node dependency to your project and in your
webpack.config.js
add:
const BundleTracker = require("webpack-bundle-tracker");
// ...
module.exports = {
// ...
plugins: [
// ...
new BundleTracker({
filename: "./myapp/static/webpack-stats.json"
}),
// ...
],
// ...
};
You can place the webpack-stats.json
file anywhere in the application. By
default Flask-Bundler will check for webpack-stats.json
inside the
application's static folder.
Afterwards, just initialize Flask-Bundler like you would with any extension.
from flask import Flask
from flask_bundler import Bundler
app = Flask(__name__)
# ...
bundler = Bundler(app)
from flask import Flask
from flask_bundler import Bundler
bundler = Bundler()
def create_app():
app = Flask(__name__)
# ...
bundler.init_app(app)
# ...
return app
When initializing Bundler, you can specify a few options.
stats_file
Path to the webpack-stats.json. Defaults to
{app.static_folder}/webpack-stats.json.
custom_renderers
A dictionary of custom renderers. str.format
will be called on the given
string with the public path of the asset as the only parameter. The default
renderers are css
and js
, but additional renderers can be passed if your
application contains other types of outputs.
strict
If True, an error will be raised in exceptional situations. Otherwise, a warning will be issued and the empty string will be returned for the bundle.
