postcss-transform-classes

npm install --save postcss-transform-classes

Transforms all classes in a CSS file.

import { camelCase } from 'lodash';
import transformClasses from 'postcss-transform-classes';

return postcss([
  transformClasses({
    transform: camelCase,
  }),
])
  .process(...)

By default will throw if two different classes produce the same output. In the example above, an error would be thrown if you had .foo-bar and .fooBar. You can disable this by setting allowConflicts: true.
