CSS Modules: Extract Imports

Transforms:

:local(.continueButton) {
  composes: button from "library/button.css";
  color: green;
}

into:

:import("library/button.css") {
  button: __tmp_487387465fczSDGHSABb;
}
:local(.continueButton) {
  composes: __tmp_487387465fczSDGHSABb;
  color: green;
}

Specification

• Only a certain whitelist of properties are inspected. Currently, that whitelist is ['composes'] alone.
• An extend-import has the following format:

composes: className [... className] from "path/to/file.css";

Options

• failOnWrongOrder bool generates exception for unpredictable imports order.

.aa {
  composes: b from "./b.css";
  composes: c from "./c.css";
}

.bb {
  /* "b.css" should be before "c.css" in this case */
  composes: c from "./c.css";
  composes: b from "./b.css";
}
