[zy445566]

I can use this method at vue2

<script>
const AComponent = {name:'a'}
// doSomeThing(AComponent)
export default AComponent 
</script>

but...How to do at vue3 when I use the setup script.
I try vue plugin,but install run at after export

You can't. You would have to do that in a separate file.

Thanks. but I finally got it by the vite plugin😂. like it

export function getDefineCompentPlugin(): {
  name: string;
  transform(code: string, id: string): string | undefined;
} {
  return {
    name: "get-define-compent-plugin",
    transform(code: string, id: string) {
      if (id.endsWith(".vue")) {
        if (/myDefineFunction[\s]*\(/.exec(code)) {
          code = code.replace(
            /export[\s]+default[\s]+(.*)/,
            "const _export_define_component = $1"
          );
          code += `\nexport default myDefineFunction(_export_define_component );\n`;
        }
        return code;
      }
    },
  };
}
