Package Management

Package Management

Package.json Requirements

When creating or modifying subpackages:

{
    "name": "@cdk-constructs/{package-name}",
    "version": "0.1.0",
    "main": "dist/src/index.js",
    "types": "dist/src/index.d.ts",
    "files": ["dist"],
    "dependencies": {
        "@cdk-constructs/cdk": "*",
        "@cdk-constructs/aws": "*"
    },
    "peerDependencies": {
        "aws-cdk-lib": "^2.225.0",
        "constructs": "^10.0.0"
    },
    "devDependencies": {
        "aws-cdk-lib": "2.225.0",
        "constructs": "10.4.2"
    }
}

Key Points:

• Use "@cdk-constructs/*": "*" to reference workspace packages
• peerDependencies and devDependencies must match the root package's CDK version
• main and types point to dist/src/ (TypeScript compiles from src/)

Inter-Package Dependencies

Some packages depend on others:

• @cdk-constructs/codeartifact depends on @cdk-constructs/aws
• @cdk-constructs/cloudwatch depends on both @cdk-constructs/cdk and @cdk-constructs/api-gateway

When adding cross-package dependencies:

1. Add them to dependencies in package.json
2. Ensure proper build order in tsconfig.build.json
3. Verify no circular dependencies are created

CDK Version Management

Version Synchronization

All packages must use the same aws-cdk-lib version. The current version is defined in the root package.json.

Updating CDK Version

When updating CDK version, modify these files:

1. Root package.json: version, devDependencies.aws-cdk-lib, devDependencies.aws-cdk, peerDependencies.aws-cdk-lib
2. Each packages/*/package.json: peerDependencies.aws-cdk-lib, devDependencies.aws-cdk-lib

Workspace Dependencies

Using Workspace References

Packages reference each other using "*" in dependencies:

{
    "dependencies": {
        "@cdk-constructs/aws": "*",
        "@cdk-constructs/cdk": "*"
    }
}

The "*" tells npm to use the workspace version, preventing circular dependencies.

Postinstall Script

The postinstall script removes nested node_modules to prevent circular dependencies:

"postinstall": "rm -rf node_modules/@cdk-constructs/*/node_modules"

This ensures all packages use the workspace root's node_modules.
