Bragg: AWS Lambda Web Framework

Bragg is a concise AWS Lambda web framework that provides a Koa.js-inspired middleware pattern for handling serverless HTTP requests. It simplifies the process of building API Gateway-backed Lambda functions by allowing developers to chain middleware functions that operate on a `ctx` (context) object. As of its current stable version, 1.4.0, Bragg maintains a focused scope, emphasizing a clear request-response cycle and robust error handling through its `app.onError()` mechanism, which supports asynchronous cleanup processes. Its release cadence appears stable rather than rapid, indicating a mature project. A key differentiator is its straightforward approach to promise resolution for `ctx.body`, automatically awaiting results before sending the Lambda response. It requires Node.js version 4 or higher.
