-### Webpack bug
-
-If you have `require('deepmerge')` (as opposed to `import merge from 'deepmerge'`) anywhere in your codebase, Webpack 3 and 4 have a bug that [breaks bundling](https://github.com/webpack/webpack/issues/6584).
-
-If you see `Error: merge is not a function`, add this alias to your Webpack config:
-
-```
-alias: {
-	deepmerge$: path.resolve(__dirname, 'node_modules/deepmerge/dist/umd.js'),
-}
