CSS Module localIdentName

Created by: abubakir1997

Problem

Currently react uses [filename]\_[classname]\_\_[hash] for localIdentName when using CSS Modules. This causes an issue if the filename contains a period, since a period is not a valid character in css class names.

Example

Filename: product.drawer.module.css ClassName: .SomeClass {} Generated ClassName: product.drawer_SomeClass_[hash]

Suggestion

• Remove the period from the class name (Allowing for period filenames)
• Or, clarify in the docs that filenames should not contain invalid css class name characters such as periods.
