Obsidian SDK Patterns

Overview

Six production patterns that prevent the most common Obsidian plugin bugs: lost settings on upgrade, null-reference crashes on deleted files, memory leaks from unregistered events, stale metadata, and UI jank from rapid file changes. Each pattern is self-contained and copy-pasteable.

Prerequisites

• A working Obsidian plugin (see obsidian-core-workflow-a)
• TypeScript strict mode enabled ("strictNullChecks": true in tsconfig)
• Familiarity with Plugin.onload() / onunload() lifecycle

Instructions

Step 1: Typed settings with versioned migration
