EAS Build configuration starts with your eas.json file, where you define build profiles for iOS and Android with platform-specific settings, credentials, and environment variables. Set up separate profiles for development, preview, and production to manage different signing certificates and provisioning requirements for each build variant.

EAS Build handles credential management by securely storing iOS certificates and provisioning profiles, plus Android keystores. You configure signing per profile in eas.json; EAS manages the secure storage and injection during cloud builds, eliminating manual certificate handling for your team.

Yes, EAS Build integrates with GitHub Actions and other CI/CD platforms to automate builds on every commit or pull request. Trigger builds programmatically via the EAS CLI within your pipeline, enabling fully automated production deployments without manual build steps.

EAS Build supports custom native builds when your Expo app requires native modules or platform-specific modifications. Configure custom build settings in eas.json to run native build steps; local builds let you test custom configurations before cloud deployment.

EAS Build supports monorepo structures with proper path configuration in eas.json to locate your app root and dependencies. Monorepo builds work with environment variables and build caching, though you must ensure correct working directory and dependency resolution across workspaces.

EAS Build provides detailed build logs and error messages in the cloud dashboard. Common failures stem from misconfigured credentials, missing environment variables, or incompatible native dependencies; check eas.json profiles, verify signing setup, and use local builds to replicate and debug issues before resubmitting.
