Laplacenoma

Laplacenoma is a reactivity analyzer built on top of the TypeScript language service, inspired by the reactivity visualization feature in vuejs/language-tools. Its goal is to provide framework-agnostic and configurable reactivity analysis.

Installation

  ts: typeof import("typescript"),
  languageService: ts.LanguageService,
  fileName: string,
  position: number,
) {
  const program = languageService.getProgram()!;
  const sourceFile = program.getSourceFile(fileName)!;
  return analyzer.analyze(sourceFile, position, {
    typescript: ts,
    languageService,
  });
}
