Mobile App (`apps/mobile`)

The mobile application is built with Expo and React Native. It provides the same core functionality as the web app, including authentication, workspace management, task tracking, and invitations, through a native mobile interface.

Architecture

The mobile app follows the same client-only pattern as the web app. It consumes API_BASE_URL from Expo config and communicates exclusively with the API server.

Mobile App -> Axios Client -> API Server (apps/api)

There is no local database or offline-first logic. The app is a thin client that delegates all business logic to the API.

Key Modules

Module	Path	Purpose
Environment	`lib/env.ts`	Runtime configuration read from Expo's config system, not from `process.env` directly
Auth Token	`lib/auth-token.ts`	Secure token storage using the platform's native secure storage mechanisms
Axios Client	`lib/axios.ts`	Pre-configured Axios instance pointing to `API_BASE_URL` with auth token injection
Client API	`lib/client-api.ts`	Typed API client methods wrapping Axios calls with proper request/response typing
Client Auth	`lib/client-auth.ts`	Authentication flow logic: sign-up, sign-in, token refresh, and session management
URL State	`lib/url-state.ts`	Navigation state management adapted for React Navigation rather than browser URLs
Session Store	`stores/session-store.ts`	Centralized session state management for the authenticated user context

Component Test Suites

The mobile app maintains full component test coverage:

Component	Test File
`AuthForm`	`components/AuthForm.test.tsx`
`CreateWorkspaceForm`	`components/CreateWorkspaceForm.test.tsx`
`CreateTaskForm`	`components/CreateTaskForm.test.tsx`
`CreateInvitationForm`	`components/CreateInvitationForm.test.tsx`
`AcceptInvitationForm`	`components/AcceptInvitationForm.test.tsx`
`SignOutButton`	`components/SignOutButton.test.tsx`
`AuthBootstrapProvider`	`components/AuthBootstrapProvider.test.tsx`

Unit Test Suites

Core utility modules have dedicated unit tests:

Module	Coverage
`env`	Environment config resolution
`auth-token`	Token storage read/write/clear
`axios`	Client configuration and interceptors
`client-api`	API method typing and request construction
`client-auth`	Auth flow state transitions
`url-state`	Navigation state serialization
`session-store`	Session state management
