Obsidian Rate Limits

Overview

Obsidian has no traditional API rate limits, but it runs on Electron with a single-threaded UI. This skill covers debouncing, batching, throttling, and async queue patterns to keep plugins responsive and prevent UI freezes.

Prerequisites

• Understanding of JavaScript event loop and requestAnimationFrame
• Familiarity with async/await and Promises
• Working Obsidian plugin with file operations

Instructions

Step 1: Debounce vault.on('modify') Events

vault.on('modify') fires on every keystroke when a user types in a note. Without debouncing, your handler runs hundreds of times per second.

import { Plugin, TFile, debounce } from 'obsidian';
