The purpose of this package is to generate CSS with arbitrary classes that have sourcemaps to arbitrary lines in JS (at runtime). This may be useful for CSS-in-JS abstractions.

Because parsing and generating sourcemaps is expensive, this package provides a web worker implementation so it can be performed off the main thread.

className: string,
stackInfo: ErrorLikeObject,

| {id: "invalidate"};

{id: "render_css", css: string};
