serverless-middleware

Serverless Framework plugin (v3.4.0) enabling middleware chaining directly in serverless.yaml for AWS Lambda functions. Allows defining pre/post handlers, error catches, and execution termination via context.end(). Supports Node.js 14+ (12x–22x) and ES6 modules since v3.2.0. Differentiator: no code changes required—all wiring in YAML; supports mixed then/catch chains and TypeScript with webpack workaround. Released semi-annually, breaking changes limited to runtime/Serverless major bumps.
