JavaScript

Reproducing an issue with treeshaking

yarn install
yarn build
yarn analyze-bundle

Observe that the whole mdi.js is imported (at 2.6MB) even though only a few icons are used

package.json has

   "sideEffects": [
    "*.scss",
    "*.css"
  ],

Babel is configured with "modules": false
webpack config has:
- usedExports: true,
- terser 3 passes

Solution

Removing devtool setting fixes this.
