Webpack doesn’t resolve properly my alias

Resolving the alias to the absolute path should do the trick:

resolve: {
  alias: {
    myApp: path.resolve(__dirname, 'src'),
  },
  extensions: ['', '.js', '.jsx']
}

Check this webpack resolve alias gist with a simple example.

Another solution to limit the number of relative paths is to add your ./src folder as root instead of aliasing it:

resolve: {
  root: [path.resolve('./src')],
  extensions: ['', '.js', '.jsx']
}

Then you will be able to require all folders inside ./src as if they where modules. For example, assuming you have the following directory structure:

.
├── node_modules
├── src
│   ├── components
│   └── utils

you would be able to import from components and utils like this:

import Header from 'components/Header';
import { myMethod } from 'utils/myUtils';

Something like having an alias for each folder inside ./src.
