Obsidian Data Handling

Overview

Data management patterns for Obsidian plugins: plugin config with loadData/saveData, vault file I/O, frontmatter parsing via metadataCache, handling renames and deletes, cross-device sync considerations, and IndexedDB fallback for large datasets.

Prerequisites

• Working Obsidian plugin (export default class extends Plugin)
• Understanding of Obsidian's Vault and MetadataCache APIs
• TypeScript compilation configured

Instructions

Step 1: Plugin Config with loadData / saveData

Obsidian stores plugin data in .obsidian/plugins/<plugin-id>/data.json. Use loadData() and saveData() — never read that file directly.
