Regex exclude a folder from node_modules - regex

Question

I am currently using webpack and running a test that goes through node_modules and excludes one specific module.
However, i am struggling with the regular expression as i am trying it on the regex checker, and it works fine. However, on the webpack it fails.
Example: https://regex101.com/r/rO4jD0/34
^node_modules\/(?!example).*
On the webpack itself, i am writing the following:
vendor: {
test: /^[\\/]node_modules[\\/](?!example).*[\\/]/,
// test: /^[\\/]node_modules[\\/](?!example)[\\/].*/,
// test: /^node_modules\/(?!example).*/,
name: 'vendor',
chunks: 'all',
}
The tests are examples of the tests i've run so far but unfortunately all of them failed.
As an FYI - this works fine but it doesnt exclude that one example folder.
test: /[\\/]node_modules[\\/]/,

Answer 1

Is this to split out a large vendor module into its own bundle? Here is how I did that:
vendor: {
name: 'vendor',
test: /[\\/]node_modules[\\/]((?!(example.js|slick-carousel)).*)[\\/]/,
name: 'vendors',
chunks: 'all'
},
v_example: {
test: /[\\/]node_modules[\\/]((example.js).*)[\\/]/,
name: 'v_example',
chunks: 'all'
},
v_slick: {
test: /[\\/]node_modules[\\/]((slick-carousel).*)[\\/]/,
name: 'v_slick',
chunks: 'all'
}
