Rollup with absolute Typescript imports


Rollup bundles it fine, but it throws some warnings for wrong source maps (Error when using sourcemap for reporting an error: Can't resolve original location of error.). The root of the problem seems to be @babel/preset-react development: true (setting it false makes the warning disappear). Am I doing something wrong, or this is expected behavior? The generated code seems fine to me...

There is also a warning about 'this' has been rewritten to 'undefined', seems related because it disappears when switching off that option.


Solution

  • At the end, I decided to disable development: true and set it to false. Definitely it should not be true when building libraries.
