EAS Build Preparation

Prepare for an EAS build by validating all configuration, credentials, and environment settings. This command does NOT run the build - it ensures everything is ready and provides the exact command to run.

Workflow Overview

1. Gather build parameters - Platform, profile, submission preference
2. Validate configuration - eas.json, app.config.js
3. Check credentials - iOS certificates, Android keystore, push notifications
4. Verify environment - Environment variables, secrets
5. Run pre-flight checks - expo doctor, native dependencies
6. Output ready-to-run command - With all validated parameters

Interactive Setup

Use AskUserQuestion to gather build parameters:

AskUserQuestion({
  questions: [
    {
      question: "Which platform are you building for?",
      header: "Platform",
      options: [
        {
          label: "iOS",
          description: "Build for iPhone/iPad",
        },
        {
          label: "Android",
          description: "Build for Android devices",
        },
        {
          label: "Both",
          description: "Build for iOS and Android",
        },
      ],
      multiSelect: false,
    },
    {
      question: "Which build profile?",
      header: "Profile",
      options: [
        {
          label: "development",
          description: "Dev client build for local development",
        },
        {
          label: "preview",
          description: "Internal testing build (TestFlight/Internal track)",
        },
        {
          label: "production",
          description: "Production build for app store release",
        },
      ],
      multiSelect: false,
    },
    {
      question: "Auto-submit after build completes?",
      header: "Submit",
      options: [
        {
          label: "Yes, auto-submit (Recommended for iOS)",
          description: "Automatically submit to TestFlight/Play Store",
        },
        {
          label: "No, just build",
          description: "Build only, submit manually later",
        },
      ],
      multiSelect: false,
    },
  ],
});
