TimeSafari Daily Notification Plugin Integration Checklist

Author: Matthew Raymer
Version: 2.0.0
Created: 2025-01-27 12:00:00 UTC
Last Updated: 2025-01-27 18:00:00 UTC
Audit Status: Pending Observability & Security review (see Phases 7, 9). Auto-update to "Passed" with date when all Phase 9 checkboxes are complete and evidence artifacts are archived.

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 Web (PWA), 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.x target (upgrade-in-Phase-2), TypeScript, Jest 30.x (align with host)
  • Version skew noted: Plugin currently pins Capacitor 5.x; host app runs Capacitor 6.2.x. Remove this line once Phase 2 'Capacitor Version Compatibility' is marked complete and the README compat matrix is updated.

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
  • Test TypeScript compilation in integrated environment

  • Ensure no transitive dependency locks the plugin to older vite/rollup plugin APIs
  • Verify exports map resolution (ESM-first) in Vite 5 cold-start and SSR (if used)
  • Add bundle-size guard (rollup-plugin-visualizer or vite's --mode analyze) with a performance budget

Phase 9: Monitoring, Observability & Compliance

9.1 Observability Hooks

  • Add structured log schema and log levels; ensure logs are redactable
  • Log-level policy documented: default INFO, overridable at runtime; sampling controls noted for DEBUG in production
  • Expose metrics (schedules created, fires, deferrals, failures, user opt-outs)
  • Optional trace hooks (init → schedule → fire → callback)
