CDK Booster - Speeding Up Bundling of Lambda Handlers

CDK Booster is a tool that accelerates AWS CDK builds by bundling all Lambda functions simultaneously instead of sequentially. It works as a drop-in replacement requiring only npm installation and a small cdk.json modification. The tool prevents duplicate bundling when CDK synthesis runs multiple times and uses ESbuild's multiple entry points for significant speed improvements, particularly beneficial for large projects with many TypeScript/JavaScript Lambda functions.
