    Bot Framework Emulator

    Bot Framework Emulator

    Locally test and debug chat bots built with the Bot Framework SDK

    Bot Framework Emulator is a desktop application that allows bot developers to test and debug bots, either locally or remotely. Using the Emulator, you can chat with your bot and inspect the messages that your bot sends and receives. The Emulator displays messages as they would appear in a web chat UI and logs JSON requests and responses as you exchange messages with your bot. Before you deploy your bot to the cloud, run it locally and test it using the Emulator. You can test your bot using the Emulator even if you haven't yet created it with Azure Bot Service or configured it to run on any channels. Before connecting your bot to the Bot Framework Emulator, you need to run your bot locally. You can use Visual Studio or Visual Studio Code to run your bot, or use the command line. When you are developing behind a corporate proxy, the Emulator will use the configured environment variables HTTP_PROXY and HTTPS_PROXY, which specify the proxy URL route for HTTP and HTTPs requests.

    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.

    GraphQL WebSocket

    Coherent, zero-dependency, lazy, simple, GraphQL

    Coherent, zero-dependency, lazy, simple, GraphQL over WebSocket Protocol compliant server and client. Messages are represented through the JSON structure and are stringified before being sent over the network. They are bidirectional, meaning both the server and the client must conform to the specified message structure. Connection is a connection within the established socket describing a "connection" through which the operation requests will be communicated. The server can close the socket (kick the client off) at any time. The close event dispatched by the server is used to describe the fatal error to the client. The client closes the socket and the connection by dispatching a 1000: Normal Closure close event to the server indicating a normal closure.

    Geek Navigation

    Geek Navigation

    Navigation Station for Independent Developers!

    Geek Ape Navigation. Navigation Station for Independent Developers! It originated from Tencent Navigation Station. At that time, when I first came into contact with the front end, I was looking for a website to imitate. This navigation station was born. The previous version added navigation to modify HTML, the JSON version solved the problem of managing navigation modification code, and managed all navigation in the form of managing JSON files. The management and navigation of the above version is still too cumbersome. Starting from this version, the database is used for management. The Vue family bucket is used in the front desk, the framework used by the server is Express, and the database is Mongodb. Vue dynamic navigation is a single-page method, which is very unfavorable for SEO optimization, so the Nuxt SSR method is used instead, which is also the biggest change in this version.

    Blazing fast, simple and complete solution for micro frontends

    Qiankun enables you and your teams to build next-generation and enterprise-ready web applications leveraging Micro Frontends. It is inspired by and based on single-spa. Qiankun was birthed internally in our group during the time web app development by distributed teams had turned to complete chaos. We faced every problem the micro frontend was conceived to solve, so naturally, it became part of our solution. After solving these common problems of micro frontends and lots of polishing and testing, we extracted the minimal viable framework of our solution, and named it qiankun, as it can contain and serve anything. Not long after, it became the cornerstone of hundreds of our web applications in production, and we decided to open-source it to save you the suffering. Inside the examples folder, there is a sample Shell app and multiple mounted Micro FE apps. To get it running, first clone qiankun.

    After.js

    After.js

    Next.js-like framework for server-rendered React apps

    Next.js is awesome. However, its routing system isn't for me. IMHO React Router is a better foundation upon which such a framework should be built, and that's the goal here. Routes are just components and don't / should not have anything to do with folder structure. Static route configs are fine. Next.js's getInitialProps was/is a brilliant idea. Route-based code-splitting should come for free or be easy to opt into. Route-based transitions/analytics/data loading/preloading etc., should either come for free or be trivial to implement on your own. After.js enables Next. js-like data fetching with any React SSR app that uses React Router. You can quickly bootstrap an SSR React app with After.js using Razzle. While Razzle is not required, this documentation assumes you have the tooling setup for an isomorphic React application. Refer to Razzle's docs for tooling, babel, and webpack customization.

    Hydrogen

    Hydrogen

    Run code interactively, inspect data, and plot

    Hydrogen is an interactive coding environment that supports Python, R, JavaScript and other Jupyter kernels. Hydrogen was inspired by Bret Victor's ideas about the power of instantaneous feedback and the design of Light Table. Running code inline and in real-time is a more natural way to develop. By bringing the interactive style of Light Table to the rock-solid usability of Atom, Hydrogen makes it easy to write code the way you want to. You also may be interested in our latest project – interact – a desktop application that wraps up the best of the web-based Jupyter notebook. Watch expressions let you keep track of variables and re-run snippets after every change. Completions from the running kernel, just like autocomplete in the Chrome dev tools. Code can be inspected to show useful information provided by the running kernel. One kernel per language (so you can run snippets from several files, all in the same namespace).
