    AWS SAM CLI

    AWS SAM CLI

    CLI tool to build, test, debug, and deploy Serverless applications

    The AWS Serverless Application Model (SAM) CLI is an open-source CLI tool that helps you develop serverless applications containing Lambda functions, Step Functions, API Gateway, EventBridge, SQS, SNS and more. The AWS Serverless Application Model (SAM) is an open-source framework for building serverless applications. It provides shorthand syntax to express functions, APIs, databases, and event source mappings. With just a few lines per resource, you can define the application you want and model it using YAML. During deployment, SAM transforms and expands the SAM syntax into AWS CloudFormation syntax, enabling you to build serverless applications faster. To get started with building SAM-based applications, use the SAM CLI. SAM CLI provides a Lambda-like execution environment that lets you locally build, test, debug, and deploy AWS serverless applications.

    MIDWAY

    MIDWAY

    Serverless Framework for front-end/full-stack developers

    A Node.js serverless framework for front-end/full-stack developers. Build the application for next decade. Works on AWS, Alibaba Cloud, Tencent Cloud, and traditional VM/Container. Super easy integrate with React and Vue. There are many similar frameworks in the community, so why do you need Midway? Midway is a framework that Alibaba has been developing continuously. Before egg was used as the underlying framework, an application-oriented framework was required to connect with the group's scenarios. The full use of TypeScript is the trend for a period of time in the future, and iterating and developing for the future is a requirement for the innovation of the architecture team. Although the community already has a framework like Nest, the maintenance, collaboration, and modification of these products will be restricted by commercial products, and it is impossible to achieve rapid iteration and security assurance of requirements. The overall R&D concept is also different from ours.

    Micro Cloud

    Micro Cloud

    A distributed OS built for the Cloud

    Micro addresses the key requirements for building services in the cloud. It leverages the microservices architecture pattern and provides a set of services which act as the building blocks of a platform. Micro deals with the complexity of distributed systems and provides simpler programmable abstractions to build on. Micro is the all encompassing end to end platform experience from source to running and beyond built with a developer first focus. Micro’s goal is to abstract away the complexity of building services for the Cloud. The cloud itself has gone through a huge boom through managed Compute and infrastructure services from the likes of AWS and others. It’s taken what was an operational burden and turned it into a suite of fully managed on demand services which can be used via APIs. Micro is built as a microservices architecture and abstracts away the complexity of the underlying infrastructure.

    gorilla/mux

    gorilla/mux

    HTTP router and URL matcher for building Go web servers

    Package gorilla/mux implements a request router and dispatcher for matching incoming requests to their respective handler. The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, mux.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are that it implements the http.Handler interface so it is compatible with the standard http.ServeMux, requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers, URL hosts, paths and query values can have variables with an optional regular expression. Also, registered URLs can be built, or "reversed", which helps maintaining references to resources, Routes can be used as subrouters: nested routes are only tested if the parent route matches. And many more features.
