Turn on Production Mode

During development, Strudel provides a lot of warnings to help you with common errors and pitfalls. However, these warning strings become useless in production and bloat your app’s payload size.

With Build Tools

When using a build tool like Webpack, the production mode will be determined by process.env.NODE_ENV inside source code, and it will be in development mode by default. Webpack provide a way to overwrite this variable to enable production mode, and warnings will be stripped by minifiers during the build. It can be done following way:

Webpack 4

module.exports = {
mode: 'production'

Webpack 3 and earlier

const webpack = require('webpack');

module.exports = {
// ...
plugins: [
// ...
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify('production')

Without Build Tools

If you are somehow using the full build, i.e. directly including Strudel via a script tag without a build tool, make sure to use the minified version (strudel.min.js) for production.
