babel-plugin-add-filehash

babel-plugin-add-filehash

This Babel plugin makes sure the Babel output changes whenever the input file changes, even if it are only trivial/whitespace changes.

This makes sure subsequent tools like webpack reprocess the file and show updated eslint messages/... It specificall works around a webpack bug that loses error messages on "unchanged" files: https://github.com/webpack/webpack/issues/2538

Installation

With npm:

npm install --save-dev babel-plugin-add-filehash

Or with yarn:

yarn --dev babel-plugin-add-filehash

After installation of the package you need to add the plugin to your project's .babelrc:

{
  "plugins": ["add-filehash"]
}
