busy-praying

A prayer times SPA built with Nuxt 3, Vuetify 3, and Pinia. Fetches daily prayer times via the Al Adhan API based on the user's configured city and country. Syncs those times to your Outlook or Google Calendar as recurring events.

Tech Stack

Nuxt 3 — SSR-disabled, static-target SPA
Vuetify 3 — UI component library (Material Design)
Pinia with pinia-plugin-persistedstate — state management
Al Adhan API — prayer times data source
country-state-city — country/city selection
@azure/msal-browser — Microsoft identity / Outlook Calendar auth

Setup

# ChromeDriver downloads are blocked in some environments; skip them if needed
CHROMEDRIVER_SKIP_DOWNLOAD=true npm install --legacy-peer-deps

Development

# Serve with hot reload at localhost:3000
npm run dev

# Build for production
npm run build

# Generate static site
npm run generate

Environment Variables

Variable	Required	Description
`NUXT_PUBLIC_MSAL_CLIENT_ID`	For Outlook sync	Azure AD application (client) ID

Create a .env file at the project root:

NUXT_PUBLIC_MSAL_CLIENT_ID=your-azure-client-id-here

Testing

Unit Tests (Jest)

Unit tests cover Pinia stores, calendar provider integrations, and the sync composable. They run in Node and require no browser or network access.

npm run test:unit

Coverage is collected from stores/, plugins/, integrations/, and composables/. A full report is written to coverage/.

E2E Tests (Nightwatch + ChromeDriver)

E2E tests require a running dev server and Chrome. Run them in two terminals:

# Terminal 1 — start the dev server
npm run dev

# Terminal 2 — run E2E tests
npm run test:e2e

If npm install fails due to a blocked ChromeDriver download, skip it:

CHROMEDRIVER_SKIP_DOWNLOAD=true npm install --legacy-peer-deps

Then point Nightwatch at a manually installed ChromeDriver or a running ChromeDriver service by editing nightwatch.conf.js.

# JS + Vue linting (ESLint)

npm run lint:style

# Run all linters

Outlook Calendar Sync — Local Setup

To test the Outlook sync feature you need an Azure AD application registration.

Register an app in Azure Portal → Microsoft Entra ID → App registrations → New registration.
Redirect URI — add http://localhost:3000 as a Single-page application redirect URI.
API permissions — add the delegated permission Calendars.ReadWrite (Microsoft Graph).

Copy the client ID from the app's Overview page and set it in .env:

NUXT_PUBLIC_MSAL_CLIENT_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Start the dev server (npm run dev), navigate to /sync, and click Connect under "Outlook / Microsoft 365". A Microsoft login popup will appear.

Note: No client secret is needed. The app uses the PKCE auth-code flow via MSAL.js, which is safe for browser SPAs without a backend.

Google Calendar Sync — Coming Soon

The GoogleProvider stub in integrations/calendar/GoogleProvider.js documents the implementation path. When ready:

Register a project in Google Cloud Console.
Enable the Google Calendar API.
Create an OAuth 2.0 client ID (Web application type) and add http://localhost:3000 as an authorised redirect URI.
Implement GoogleProvider using Google Identity Services (GIS) and the Calendar REST API (see comments in the stub file).
