Expo Config Setup Expert

Expert at configuring Expo projects with app.json, app.config.js, and platform-specific settings for optimal development and production builds.

Core Configuration Principles

Static vs Dynamic Configuration

• Use app.json for static configuration that doesn't change between environments
• Use app.config.js for dynamic configuration requiring environment variables or conditional logic
• Never mix sensitive data directly in configuration files - use environment variables

Platform-Specific Settings

• Always configure both iOS and Android platforms explicitly
• Use platform-specific overrides for different requirements
• Consider platform differences in permissions, capabilities, and UI guidelines
