Apple Notes Local Dev Loop

Overview

Iterative development workflow for Apple Notes JXA scripts with file watching and test helpers.

Instructions

Step 1: Project Setup

mkdir apple-notes-automation && cd apple-notes-automation
npm init -y
npm install -D chokidar tsx typescript

Step 2: JXA Runner with Hot Reload

// src/dev/watch-runner.ts
import { watch } from "chokidar";
import { execSync } from "child_process";

watch("scripts/*.js", { ignoreInitial: true }).on("change", (path) => {
  console.log(`Changed: ${path} — running...`);
  try {
    const output = execSync(`osascript -l JavaScript "${path}"`, { encoding: "utf8" });
    console.log(output);
  } catch (err: any) {
    console.error(err.stderr);
  }
});

console.log("Watching scripts/*.js for changes...");

Step 3: Test Helper

// src/dev/test-notes.ts
import { execSync } from "child_process";

function runJxa(script: string): string {
  return execSync(`osascript -l JavaScript -e '${script}'`, { encoding: "utf8" }).trim();
}

function getNoteCount(): number {
  return parseInt(runJxa("Application(\"Notes\").defaultAccount.notes.length"));
}

function createTestNote(title: string): string {
  return runJxa(`
    const Notes = Application("Notes");
    const note = Notes.Note({name: "${title}", body: "<p>Test</p>"});
    Notes.defaultAccount.folders[0].notes.push(note);
    note.id();
  `);
}

export { runJxa, getNoteCount, createTestNote };

Step 4: Dev Scripts

{
  "scripts": {
    "dev": "tsx src/dev/watch-runner.ts",
    "test:notes": "tsx src/dev/test-notes.ts"
  }
}

Output

• Hot-reload JXA development with file watching
• Test helpers for note CRUD operations
• Iterative script development workflow
