POS Application

A Point of Sale (POS) application built with React Native.

Environment Configuration

This project uses environment configuration for different settings and API endpoints.

Configuration Files

The configuration is located in the config/ directory:

• env.example.js - Example configuration file with all available options
• env.js - Your actual environment configuration (not tracked in git)
• index.js - Centralized configuration object and helper functions

Setup

1. Copy env.example.js to env.js:

   cp config/env.example.js config/env.js

2. Update the values in config/env.js according to your environment

Configuration Options

API Configuration

• API_BASE_URL - Base URL for your API
• API_TIMEOUT - Request timeout in milliseconds

App Configuration

• APP_NAME - Application name
• APP_VERSION - Application version
• APP_ENVIRONMENT - Environment (development, staging, production)

Security

• TOKEN_STORAGE_KEY - Key for storing authentication token
• USER_STORAGE_KEY - Key for storing user data

File System

• CACHE_DIRECTORY - Directory for caching files
• PROFILE_PICTURE_CACHE - Subdirectory for profile pictures

Toast Messages

• TOAST_DURATION - Toast message duration in milliseconds
• TOAST_POSITION - Toast message position

Development

• DEBUG_MODE - Enable/disable debug logging
• LOG_LEVEL - Logging level (debug, info, warn, error)

Usage

Import the configuration in your components:

import { CONFIG, getApiUrl, log, isDevelopment } from '../config';

// Use configuration values
const apiUrl = getApiUrl('login');
const isDev = isDevelopment();

// Log messages
log('This is a debug message', 'debug');

Environment-Specific Configurations

Development

export const ENV_CONFIG = {
  API_BASE_URL: 'http://10.0.2.2:8000/api',
  APP_ENVIRONMENT: 'development',
  DEBUG_MODE: true,
  LOG_LEVEL: 'debug',
};

Production

export const ENV_CONFIG = {
  API_BASE_URL: 'https://your-production-api.com/api',
  APP_ENVIRONMENT: 'production',
  DEBUG_MODE: false,
  LOG_LEVEL: 'error',
};

Security Notes

• Never commit config/env.js to version control
• Use different API URLs for different environments
• Disable debug mode in production
• Use secure storage keys that are environment-specific
