    Flask

    Flask

    The Python micro framework for building web applications

    Flask is a lightweight WSGI web application framework designed to help developers get started with their web applications quickly and easily with the ability to scale up to complex applications. Being a “micro” framework does not mean that your whole web application must fit into a single Python file (although it can) or that it be limited; rather it means that Flask aims to keep the core simple but extensible. Flask offers suggestions, but it won’t make any decisions for you such as what database to use or what dependencies or project layout to choose. You get to choose the tools and libraries you want to use, so Flask can be everything you need and nothing you don’t. Flask has become one of the most popular Python web application frameworks, and has amassed a great number of extensions provided by the community that make adding new functionality easy.

    Lucky

    Lucky

    A full-featured Crystal web framework that catches bugs for you

    Lucky is a web framework written in Crystal. It helps you work quickly, catch bugs at compile time, and deliver blazing-fast responses. Lucky is extremely fast and uses very little memory. You and your users will love the extra dose of speed. Authentication, asset management, CORS, database ORM, and more can all be included when creating a new Lucky project. Instead of finding bugs in QA or in production, Lucky is designed to catch as many bugs as possible at compile time. Lucky uses Action classes for handling HTTP requests and responses. The classes map the routes and parameters it handles to a response block. Lucky can generate these classes for you with ’lucky gen.action`. Using a class per action provides very solid automatic error detection, as well as the generation of routing, path, and link helpers and methods.

    Rocket

    Rocket

    A web framework for Rust

    Rocket is a web framework for Rust that makes it simple to write fast, secure web applications without sacrificing flexibility, usability, or type safety. Handling forms is simple and easy. Simply derive FromForm for your structure and let Rocket know which parameter to use. Rocket parses and validates the form request, creates the structure, and calls your function. Bad form request? Rocket doesn’t call your function! What if you want to know if the form was bad? Simple! Change the type of task to Option or Result! Rocket has first-class support for JSON, right out of the box. Simply derive Deserialize or Serialize to receive or return JSON, respectively. Like other important features, JSON works through Rocket’s FromData trait, Rocket’s approach to deriving types from body data. It works like this: specify a data route parameter of any type that implements FromData. A value of that type will then be created automatically from the incoming request body.

    Apollo Server

    Apollo Server

    Spec-compliant and production ready JavaScript GraphQL server

    Apollo Server is an open-source, spec-compliant GraphQL server that's compatible with any GraphQL client, including Apollo Client. It's the best way to build a production-ready, self-documenting GraphQL API that can use data from any source. Apollo Server provides a simple API for integrating with any Node.js web framework or serverless environment. The @apollo/server package itself ships with a minimally-configurable, standalone web server that handles CORS and body parsing out of the box. Integrations with other environments are community-maintained. Apollo Server's standalone server lets you get a GraphQL server up and running quickly without needing to set up an HTTP server yourself. It allows all the same configuration of GraphQL logic as the Express integration, but does not provide the ability to make fine-grained tweaks to the HTTP-specific behavior of your server.

    Blazor

    Blazor

    Build client web apps with C#

    Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries. Blazor is a feature of ASP.NET, the popular web development framework that extends the .NET developer platform with tools and libraries for building web apps. Blazor can run your client-side C# code directly in the browser, using WebAssembly. Because it's real .NET running on WebAssembly, you can re-use code and libraries from server-side parts of your application. Alternatively, Blazor can run your client logic on the server. Client UI events are sent back to the server using SignalR - a real-time messaging framework. Once execution completes, the required UI changes are sent to the client and merged into the DOM. Blazor uses open web standards without plug-ins or code transpilation.

    Modern.js

    The meta-framework suite designed from scratch for web development

    The meta-framework suite was designed from scratch for frontend-focused modern web development. Both "server-side routing" and "client-side routing" are supported. Serverless paradigm of "dynamic and static integrated Web". Low-threshold, full-featured, integrated "BFF" development. Modern.js provides out-of-the-box support for mainstream IDEs such as VS Code, and has features such as automatic detection and repair of Lint problems, access checks before code submission, etc., which can make code development more efficient and intelligent. The current project is a SPA application. Although the client route can simulate the effect of multiple pages, in fact, different routes use the same HTML document, so by default, the head elements such as title, meta etc. in the HTML document element are always unchanged.

    Networked-Aframe

    Networked-Aframe

    Web framework for building multi-user virtual reality experiences

    Multi-user VR on the Web. A framework for writing multi-user VR apps in HTML and JS. Built on top of A-Frame. Follow the NAF Getting Started tutorial to build your own example from scratch, including setting up a local server. Networked-Aframe works by syncing entities and their components to connected users. To connect to a room you need to add the networked-scene component to the a-scene element. For an entity to be synced, add the networked component to it. By default the position and rotation components are synced, but if you want to sync other components or child components you need to define a schema. For more advanced control over the network messages see the sections on Broadcasting Custom Messages and Options. Create an instance of a template to be synced across clients. The position and rotation will be synced by default. The buffered-interpolation is added to allow for less network updates while keeping smooth motion.
