Electron Release

Electron Release Guide

Codex Compatibility

When running this skill in Codex, translate Claude Code-only primitives before acting: AskUserQuestion -> chat/request_user_input, TodoWrite -> update_plan, Task/TaskCreate/TeamCreate/SendMessage -> spawn_agent/send_input/wait_agent when available and allowed, and EnterPlanMode/ExitPlanMode -> a concise chat plan plus explicit approval. Resolve Read/Write/Edit/Bash/WebSearch/WebFetch to Codex file/shell/web tools, and map ~/.claude/... paths to ~/.agents/... or ~/.codex/... unless the task explicitly targets Claude Code.

Cursor Compatibility

When running this skill in Cursor Agent, translate Claude Code-only primitives before acting: AskUserQuestion -> AskQuestion; TodoWrite -> Cursor TodoWrite or an equivalent checklist; Task/TaskCreate/TeamCreate/SendMessage/multi-agent flows -> Cursor Task (subagents), parallel Tasks, or run_in_background when allowed (TeamCreate/SendMessage may have no exact match); EnterPlanMode/ExitPlanMode -> Plan mode (SwitchMode / CreatePlan) plus explicit user approval. Resolve Read/Write/Edit/StrReplace/Bash/web/search/MCP via Cursor Composer or Agent equivalents. MCP names written as mcp__server__tool typically map to call_mcp_tool with configured server identifiers. Map ~/.claude/... to ~/.cursor/skills/, .cursor/skills/, and .cursor/rules/ unless the task explicitly targets Claude Code.

Complete release workflow for Electron applications with auto-update support.

Auto-Update Verification Scope

Standard releases stop after verifying the published assets and latest-mac.yml metadata. Do not install or launch an older app, trigger its updater, download an update, restart into it, or exercise ShipIt as part of this skill. Perform end-to-end auto-update QA only when the user explicitly requests it or asks to investigate a reported update failure.

Supported Configurations

Quick Start (macOS + Vite + electron-builder)

# 1. Build with notarization
APPLE_KEYCHAIN_PROFILE=your-profile pnpm build:mac

# 2. Rename ZIPs (GitHub converts spaces to dots)
cp "dist/App Name-X.Y.Z-arm64-mac.zip" "dist/App-Name-X.Y.Z-arm64-mac.zip"
cp "dist/App Name-X.Y.Z-mac.zip" "dist/App-Name-X.Y.Z-mac.zip"

# 3. Create release with ALL files
gh release create vX.Y.Z \
  dist/latest-mac.yml \
  "dist/App-Name-X.Y.Z-arm64-mac.zip" \
  "dist/App-Name-X.Y.Z-mac.zip" \
  dist/app-name-X.Y.Z-arm64.dmg \
  dist/app-name-X.Y.Z-x64.dmg \
  --title "vX.Y.Z" --notes "Release notes..."

Complete Workflow

Phase 1: Pre-Release

1. Update version in package.json
2. Commit version bump:

   git add package.json
   git commit -m "chore(release): bump version to X.Y.Z"
   git push origin main
   

Phase 2: Build

3. Build with notarization:

   APPLE_KEYCHAIN_PROFILE=your-profile pnpm build:mac
   

   Env Var	Purpose
   APPLE_KEYCHAIN_PROFILE	Keychain profile for notarization
   Alternative: APPLE_ID, APPLE_APP_SPECIFIC_PASSWORD, APPLE_TEAM_ID	Direct credentials

4. Verify build output:

   ls -la dist/*.dmg dist/*.zip dist/*.yml
   

   Expected files:

   • latest-mac.yml - Auto-update metadata
   • App Name-X.Y.Z-arm64-mac.zip - ARM64 update payload
   • App Name-X.Y.Z-mac.zip - x64 update payload
   • app-name-X.Y.Z-arm64.dmg - ARM64 installer
   • app-name-X.Y.Z-x64.dmg - x64 installer

Phase 3: Prepare Release Assets

5. Rename ZIP files (critical for auto-update):

   # GitHub converts spaces to dots, but latest-mac.yml expects hyphens
   cp "dist/App Name-X.Y.Z-arm64-mac.zip" "dist/App-Name-X.Y.Z-arm64-mac.zip"
   cp "dist/App Name-X.Y.Z-mac.zip" "dist/App-Name-X.Y.Z-mac.zip"
   

6. Verify latest-mac.yml URLs match renamed files:

   cat dist/latest-mac.yml
   # Check that 'url:' entries match your renamed ZIP filenames
   

Phase 4: GitHub Release

7. Create release with all required files:

   gh release create vX.Y.Z \
     dist/latest-mac.yml \
     "dist/App-Name-X.Y.Z-arm64-mac.zip" \
     "dist/App-Name-X.Y.Z-mac.zip" \
     dist/app-name-X.Y.Z-arm64.dmg \
     dist/app-name-X.Y.Z-x64.dmg \
     --title "vX.Y.Z" \
     --notes "$(cat <<'EOF'
   ## What's Changed
   - Feature 1
   - Bug fix 2
   EOF
   )"
   

8. Verify release assets:

   gh release view vX.Y.Z --json assets --jq '.assets[].name'
   

Required Files for Auto-Update

Common Mistakes

Troubleshooting

"Download error" on auto-update

# Check if filenames match
cat dist/latest-mac.yml | grep url:
gh release view vX.Y.Z --json assets --jq '.assets[].name'
# URLs in yml must exactly match asset names

"No updates available"

# Verify latest-mac.yml is uploaded
gh release view vX.Y.Z --json assets --jq '.assets[].name' | grep yml

Gatekeeper blocks app

# Rebuild with notarization
APPLE_KEYCHAIN_PROFILE=your-profile pnpm build:mac
# Check build log for "notarization successful"

electron-builder.yml Reference

mac:
  target:
    - target: dmg
      arch: [arm64, x64]
    - target: zip
      arch: [arm64, x64]
  notarize: true
  hardenedRuntime: true

publish:
  provider: github

Success Criteria

• Build completes with "notarization successful"
• All 5 files uploaded to GitHub Release
• ZIP filenames match latest-mac.yml URLs exactly
