The way below is to use alias. This way we save us from having to write lengthy paths, having to compare the relative position between one file and another. In general, people use alias to create the root path for the project.

2. resolve.alias

Code file webpack.config.js

Note that when we use alias, there can be two problems while writing code:

  • Eslint does not understand and reports errors.
  • The specific texteditor I am using is that VSCode does not suggest.

3. resolve.extensions

Resolve file extensions in order.

Code file webpack.config.js

If multiple files share the same name but have different extensions, webpack will resolve the one with the extension listed first in the array and skip the rest.
