    Meteor

    Meteor

    Meteor, the JavaScript App Platform

    Meteor is a full-stack JavaScript framework that streamlines building real-time web and mobile applications from a single codebase. It couples a Node.js backend with a reactive data system so UI updates propagate automatically when data changes. The framework popularized DDP (a lightweight pub/sub protocol) and a client cache (Minimongo) to mirror server collections on the client for latency-compensated interactions. A batteries-included build system, package ecosystem, and opinionated project structure reduce setup time for accounts, methods, publications, and UI integration. Historically paired with Blaze, Meteor also works well with modern front-end libraries like React, Vue, or Svelte for rendering. Its dev experience focuses on hot reloads, rapid prototyping, and predictable data flow, making it attractive for teams that want real-time features without stitching together many separate tools.

    Middy

    Middy

    The stylish Node.js middleware engine for AWS Lambda

    Middy is a very simple middleware engine that allows you to simplify your AWS Lambda code when using Node.js. If you have used web frameworks like Express, then you will be familiar with the concepts adopted in Middy and you will be able to get started very quickly. A middleware engine allows you to focus on the strict business logic of your Lambda and then attach additional common elements like authentication, authorization, validation, serialization, etc. in a modular and reusable way by decorating the main business logic. One of the main strengths of serverless and AWS Lambda is that, from a developer perspective, your focus is mostly shifted toward implementing business logic. Anyway, when you are writing a handler, you still have to deal with some common technical concerns outside business logic, like input parsing and validation, output serialization, error handling, etc.

Request data is validated using Joi. Check the documentation for more details on how to write Joi validation schemas. In production mode, only info, warn, and error logs will be printed to the console. It is up to the server (or process manager) to actually read them from the console and store them in log files.
