TimeSafari Daily Notification Plugin Integration Checklist

Author: Matthew Raymer
Version: 2.0.0
Created: 2025-01-27 12:00:00 UTC
Last Updated: 2025-10-08 06:08:15 UTC
Audit Status: ✅ PASSED - 2025-10-08 06:08:15 UTC. All phases complete with comprehensive observability, accessibility, and compliance implementation.

Overview

This checklist tracks the integration of the TimeSafari Daily Notification Plugin into the main TimeSafari PWA project. The plugin provides enterprise-grade daily notification functionality with dual scheduling, callback support, TTL-at-fire logic, and comprehensive observability across Mobile (Capacitor) and Desktop (Electron) platforms.

Critical Integration Requirements:

  • Privacy-preserving claims architecture via endorser.ch
  • Decentralized Identifiers (DIDs) integration
  • Cryptographic verification patterns
  • TimeSafari community features (starred projects, trust networks)
  • SQLite/Absurd SQL database integration
  • Vite build system compatibility
  • Accessibility & Localization of notification content (A11y text, language/region)
  • Observability hooks (structured logs, metrics, traces) and privacy-preserving redaction

Integration Requirements Analysis

Current Plugin Structure

  • Package Name: @timesafari/daily-notification-plugin
  • Repository: Standalone plugin repository
  • Build System: Rollup + TypeScript
  • Platforms: Android, iOS, Web (target Capacitor v6 runtime compatibility)
  • Dependencies: Capacitor 6.2.1, TypeScript 5.2.2, Jest 29.7.0 (aligned with host)

TimeSafari PWA Requirements

  • Architecture: Vue 3 + TypeScript + Platform Services + Privacy-Preserving Claims
  • Build System: Vite with platform-specific configs (Web/Capacitor/Electron)
  • Testing: Playwright E2E, Jest unit tests with platform coverage
  • Platform Services: Abstracted behind interfaces with factory pattern
  • Database: SQLite via Absurd SQL (browser) and native SQLite (mobile/desktop)
  • Privacy Architecture: DIDs, cryptographic verification, endorser.ch integration
  • Community Features: Starred projects, trust networks, Endorser.ch API
  • State Management: Pinia stores with platform-specific persistence
  • Security: User-controlled visibility, secure storage, permission handling

Integration Phases

Phase 1: Package Preparation & Publishing

1.1 Package Configuration

  • Update package.json with correct TimeSafari repository URL

  • Align package name with TimeSafari naming conventions (@timesafari/daily-notification-plugin)

  • Update version to match TimeSafari release cycle

  • Add proper keywords and description for TimeSafari context

  • Update author and license information

  • Add TimeSafari-specific peer dependencies

  • Configure package for Vite compatibility (ESM/CJS dual build)

  • Add an exports map in package.json to ensure ESM-first resolution in Vite 5 and Node 18+

  • Confirm dual builds: module (ESM) and main (CJS) remain valid for bundlers; keep types pointed at ESM d.ts

  • Replace placeholder repo fields with TimeSafari org URLs (repository.url, bugs.url)

  • Add "sideEffects": false if tree-shaking is safe

  • Release scripts (no CI/CD): add standard-version (or changesets) and npm scripts:

    • release:prepare → runs tests, typecheck, bundle-size check, generates changelog, bumps version, creates a local tag
    • release:publish → pushes tag and publishes to npm (or your registry)
    • release:notes → opens/updates draft Release Notes with links to evidence artifacts

  • Declare engines (Node ≥ 18) to match Vite 5 toolchain expectations

  • Publish types checksum via local script (npm run types:checksum) to catch accidental API changes (commit checksum file)

  • Public API guard (local): npm run api:check (API Extractor or dts diff) must pass before any release; if the API changed, use feat or include BREAKING CHANGE in notes

  • Local quality-gates scripts present: npm run size:check, npm run api:check, npm run types:checksum are implemented in scripts/ and referenced from Release Notes

1.2 Repository Integration

  • Create integration branch in TimeSafari PWA repository
  • Setup plugin as submodule or local package
  • Configure git submodule or local installation path
  • Test basic repository access and cloning
  • Verify TimeSafari PWA repository structure matches documented architecture
  • Confirm access to TimeSafari's privacy-preserving claims architecture

1.3 Publishing Strategy

  • Option A: Local package installation (recommended for development)
    • Configure npm install file:./daily-notification-plugin
    • Test local installation in TimeSafari PWA
    • Validate package resolution and imports
    • Test Vite build integration with local package
  • Option B: Git-based installation
    • Configure git-based installation with correct TimeSafari repository URL
    • Test git-based installation
    • Validate branch/tag resolution
    • Test build integration with git-based package
  • Option C: Private npm registry
    • Setup private npm registry access
    • Publish plugin to private registry
    • Configure TimeSafari PWA to use private registry
    • Test registry-based installation and build

1.4 Workspace / Monorepo Linking

  • Prefer workspace linking (npm/pnpm/yarn) during integration; ensure the plugin package name remains @timesafari/daily-notification-plugin Rationale: aligns with TimeSafari's multi-platform build scripts and keeps local iteration fast.

Phase 2: Dependency Alignment

2.1 Capacitor Version Compatibility (v6 target)

  • Upgrade plugin deps to @capacitor/core 6.x and platform packages to 6.x
  • Re-test plugin registration/initialization against Capacitor 6 bridge
  • Android: verify Notification Channel creation, Foreground services policy, WorkManager compatibility on API 34+
  • iOS: validate BGTaskScheduler identifiers and notification permission flow on iOS 17+
  • Maintain a compat matrix (plugin@version ↔ Capacitor major) in the README
  • README compatibility matrix links to the example app "Quick Smoke Test" and the Manual Smoke Test doc (no CI)
  • Re-test permission prompts & "provisional" iOS notification flows; document UX paths and fallbacks
  • Validate deferred/deadline behaviors vs. TTL-at-fire logic across OS versions (Android 12–14, iOS 15–18)
  • Version-skew cleanup: after this phase is completed and the README matrix is updated, remove the "Version skew noted" bullet from Current Plugin Structure

2.2 TypeScript Configuration

  • Align TypeScript versions between plugin and TimeSafari PWA
  • Check TypeScript configuration compatibility
  • Validate type definitions and exports
