React Native Semantic Versioning Sync

A comprehensive library for managing semantic versions and build numbers across React Native iOS and Android projects following SemVer 2.0.0 specification.

✨ Features

• 🔧 SemVer 2.0.0 Compliance: Strict adherence to semantic versioning specification
• 📱 Cross-Platform Sync: Automatic version synchronization between package.json, iOS, and Android
• 🔢 Build Number Management: Proper build number handling for App Store/Google Play requirements
• 🚀 CLI Interface: Easy-to-use command-line interface
• 📚 Programmatic API: TypeScript API for Node build scripts (not for RN runtime)
• ⚡ Zero Configuration: Works out of the box with standard React Native projects
• 🛡️ Type Safe: Full TypeScript support with comprehensive type definitions

📦 Installation

Install as a development dependency:

npm install --save-dev react-native-semver-sync
# or
yarn add -D react-native-semver-sync

🚀 Quick Start

CLI Usage

# Increment patch version (1.0.0 → 1.0.1)
npx rn-semver patch

# Increment minor version (1.0.1 → 1.1.0, patch resets to 0)
npx rn-semver minor

# Increment major version (1.1.0 → 2.0.0, minor and patch reset to 0)
npx rn-semver major

# Sync current package.json version to platforms
npx rn-semver sync

Programmatic Usage (Node scripts only)

import { syncVersions, incrementVersion } from 'react-native-semver-sync';

// Sync current package.json version
const result = await syncVersions();

// Increment version and sync
const patchResult = await incrementVersion('patch');
console.log(`Updated to version ${patchResult.version.version}`);

📚 Semantic Versioning Rules

This library follows SemVer 2.0.0 specification strictly:

Version Format: MAJOR.MINOR.PATCH

• MAJOR: Breaking changes (incompatible API changes)
• MINOR: New features (backward compatible)
• PATCH: Bug fixes (backward compatible)

Reset Rules

• PATCH version MUST be reset to 0 when MINOR is incremented
• PATCH and MINOR MUST be reset to 0 when MAJOR is incremented

Build Numbers

• Always increment (never reset)
• Required for App Store/Google Play (must be higher than previous)
• Internal identifier, not visible to users

🔧 CLI Commands

Basic Commands

rn-semver patch     # Bug fix release (1.0.0 → 1.0.1)
rn-semver minor     # Feature release (1.0.1 → 1.1.0)
rn-semver major     # Breaking change release (1.1.0 → 2.0.0)
rn-semver sync      # Sync current version to platforms
rn-semver help      # Show help information

Options

--verbose, -v       # Enable verbose logging
--ios-only          # Update iOS only
--android-only      # Update Android only
--help, -h          # Show help

Examples

# Bug fix with verbose output
rn-semver patch --verbose

# Feature release for iOS only
rn-semver minor --ios-only

# Major release for Android only
rn-semver major --android-only

📱 Platform Support

iOS

Updates the following in ios/*.xcodeproj/project.pbxproj:

• MARKETING_VERSION: User-facing version (e.g., "1.2.3")
• CURRENT_PROJECT_VERSION: Build number (e.g., "42")

Android

Updates the following in android/app/build.gradle:

• versionName: User-facing version (e.g., "1.2.3")
• versionCode: Build number (e.g., 42)

🛠️ API Reference

Functions

syncVersions(options?)

Syncs the current package.json version to iOS and Android platforms.

import { syncVersions } from 'react-native-semver-sync';

const result = await syncVersions({
  platforms: ['ios', 'android'], // Default: both
  verbose: true,                  // Default: false
});

incrementVersion(type, options?)

Increments the package.json version and syncs to all platforms.

import { incrementVersion } from 'react-native-semver-sync';

const result = await incrementVersion('patch', {
  platforms: ['ios'],
  verbose: true,
});

Note: Convenience functions like incrementPatch, incrementMinor, incrementMajor are not exported. Use incrementVersion('patch' | 'minor' | 'major') instead, preferably via the CLI.

VersionManager Class

For advanced usage:

import { VersionManager } from 'react-native-semver-sync';

const manager = new VersionManager({
  config: {
    iosProjectPath: './ios/MyApp.xcodeproj/project.pbxproj',
    androidGradlePath: './android/app/build.gradle',
    packageJsonPath: './package.json',
  },
  platforms: ['ios', 'android'],
  verbose: true,
});

const result = await manager.syncVersions();

Types

interface SyncResult {
  success: boolean;
  version: VersionInfo;
  build: BuildInfo;
  platforms: PlatformUpdateResult[];
  errors: string[];
}

interface VersionInfo {
  version: string;
  major: number;
  minor: number;
  patch: number;
  prerelease?: string;
  buildMetadata?: string;
}

⚙️ Configuration

Default Paths

The library automatically detects standard React Native project structure:

your-project/
├── package.json                          # Version source
├── ios/YourApp.xcodeproj/project.pbxproj # iOS versions
└── android/app/build.gradle              # Android versions

Custom Paths

import { syncVersions } from 'react-native-semver-sync';

await syncVersions({
  config: {
    iosProjectPath: './ios/CustomApp.xcodeproj/project.pbxproj',
    androidGradlePath: './android/app/build.gradle',
    packageJsonPath: './package.json',
  },
});

📋 NPM Scripts Integration

Add to your package.json:

{
  "scripts": {
    "version:patch": "rn-semver patch",
    "version:minor": "rn-semver minor", 
    "version:major": "rn-semver major",
    "version:sync": "rn-semver sync"
  }
}

Then use:

npm run version:patch
npm run version:minor
npm run version:major
npm run version:sync
