Change

Limited AST for Pre Extraction

{
  "type": "Object",
  "properties": [
    {
      "key": "color",
      "value": {
        "type": "String",
        "value": "red"
      },
    },
  ],
}

This feature makes it easy to create a CSS in JS library using kaze style.

Abolition of __pre***

Merge __pre*** into style & globalStyle

before

// style
export const style = <K extends string>(styles: KazeStyle<K>): Classes<K> => {
  const [cssRules, classes] = resolveStyle(styles);
  if (typeof document !== 'undefined') setCssRules(cssRules);
  return classes;
};
// __preStyle
export const __preStyle = <K extends string>(
  styles: KazeStyle<K>,
  forBuild: ForBuild<K>,
  filename: string,
  index: number,
): Classes<K> => {
  const [cssRules, classes, staticClasses] = resolveStyle(styles);
  if (forBuild[0] === filename) {
    forBuild[1].push(...cssRules);
    forBuild[2].push([staticClasses, index]);
  }

  return classes;
};

after

// style
export function style<K extends string>(styles: KazeStyle<K>): Classes<K>;
export function style<K extends string>(
  styles: KazeStyle<K>,
  buildArg: BuildArg,
  index: number,
): Classes<K>;
export function style<K extends string>(
  styles: KazeStyle<K>,
  buildArg?: BuildArg,
  index?: number,
): Classes<K> {
  const [cssRules, classes, staticClasses] = resolveStyle(styles);
  if (isBuildTime(buildArg) && typeof index !== 'undefined') {
    const classesNode = classesSerialize(staticClasses);
    buildArg.injector.cssRules.push(...cssRules);
    buildArg.injector.args.push({ value: [classesNode], index });
  } else if (typeof document !== 'undefined') setCssRules(cssRules);
  return classes;
}

TreeShake does not work at Webpack Child Compiler for NodeTarget, cause unknown.

I frustration to Single file support....

I will try to take a look this weekend 👍 Great work so far!

As for the Limited AST, it is almost complete.
However, I am struggling a lot with Single file styles.

I would like to support multiple UI libraries, but single file syles are very dependent on the behavior of the UI library.

This PR does not seem to be able to support single file styles.
