How to ignore test files in webpack with ts-loader

Question

I have a project that runs the test files named \"*.test.ts\" with jest and ts-jest. This is fine but when I launch webpack, I get errors for the test files:

ERR         


        

Answer 1

You can specify a function instead of the regular expression for the loader test property; this can give you a more control.

test: function (modulePath) {
  return modulePath.endsWith('.ts') && !modulePath.endsWith('test.ts');
}
