Just trying to make sure I am setting up my preact js correct for production.
In my webpack setup with preact, and run npm run build I notice with Bundle Analyzer Plugin the path for the preact js file is
/node_modules/preact/dist/preact.js and not
/node_modules/preact/dist/preact.min.js
I have uglify and minify js set up as well, but just thought it was curious that the minified package is not picked up ?
Entry script within webpack
entry: { app: './src/index.js', vendor: [ 'preact', 'preact-router' ] },
Npm Run build script
"build": "cross-env NODE_ENV=production webpack --progress -p --display-modules --display-chunks"
The default main for preact is dist/preact.js - preact.min.js is there for people who want to take advantage of minification when not applying their own (people hotlinking it off a CDN, for example), and to measure real-world output size.
You're already applying UglifyJS to your bundle by running webpack with the -p flag, so you needn't worry too much about trying to use dist/preact.min.js. It could save a few bytes, but nothing major. The file you're using (dist/preact.js) is actually already run through UglifyJS by Preact, it's just not compressed but not mangled (so the variable names remain intact).
