Description

there is a same name package which bundled more than one version in your application.

it is not good to the bundle size of your application.

General Solution

add an entry in resolve.alias which will 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 render all Lodash imports to always refer to the lodash instance found at ./node_modules/lodash:

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