Obsidian Upgrade Migration

Current State

!npm list 2>/dev/null | head -20 !cat manifest.json 2>/dev/null || echo 'No manifest.json in cwd'

Overview

Upgrade an Obsidian plugin between versions: migrate persisted settings with version checks, replace deprecated API calls, update manifest.json minAppVersion, and test across Obsidian releases.

Prerequisites

• Existing Obsidian plugin with source code
• Current manifest.json and versions.json
• Access to Obsidian changelog and breaking changes docs
• Node.js 18+ with npm or pnpm

Instructions

Step 1: Audit Current Version Compatibility

Check what your plugin currently targets and what the user's Obsidian version requires:

# Current plugin target
echo "=== manifest.json ==="
cat manifest.json | python3 -c "
import json, sys
m = json.load(sys.stdin)
print(f\"Plugin: {m['id']} v{m['version']}\")
print(f\"minAppVersion: {m['minAppVersion']}\")
"

# Current obsidian type definitions
echo "=== obsidian package version ==="
npm ls obsidian 2>/dev/null || echo "Not found in node_modules"

# Check versions.json for version history
echo "=== versions.json ==="
cat versions.json 2>/dev/null | python3 -m json.tool || echo "No versions.json"

Step 2: Update the Obsidian Type Definitions

# Update to latest obsidian types
npm install obsidian@latest --save-dev

# Check what changed
npm diff obsidian 2>/dev/null | head -100

Then check for TypeScript errors against the new types:

npx tsc --noEmit 2>&1 |  -50
