#Rule index

Description

There is a same name package which is bundled in multiple versions in your application.

This negatively impacts the bundle size of your application.

General Solution

Add an entry in resolve.alias to configure Webpack to route any package references to a single specified path.

For example, if lodash is duplicated in your bundle, the following configuration would make all Lodash imports refer to the lodash instance found at ./node_modules/lodash:

{
  alias: {
    lodash: path.resolve(__dirname, 'node_modules/lodash')
  }
}
