    Hyperapp

    Hyperapp

    Tiny framework for building hypertext applications

    The tiny framework for building hypertext applications. Do more with less—We have minimized the concepts you need to learn to get stuff done. Views, actions, effects, and subscriptions are all pretty easy to get to grips with and work together seamlessly. Write what, not how—With a declarative API that's easy to read and fun to write, Hyperapp is the best way to build purely functional, feature-rich, browser-based apps in JavaScript. Smaller than a favicon—1 kB, give or take. Hyperapp is an ultra-lightweight Virtual DOM, highly-optimized diff algorithm, and state management library obsessed with minimalism. Official packages provide access to The Web Platform, and ensure that the APIs are exposed in a way that makes sense for Hyperapp, and the underlying code is stable. We already cover a decent amount of features, but you can always create your own effects and subscriptions if something is not available yet.

    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.

    Protractor

    Protractor

    E2E test framework for Angular apps

    Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would. Protractor is built on top of WebDriverJS, which uses native events and browser-specific drivers to interact with your application as a user would. Protractor supports Angular-specific locator strategies, which allows you to test Angular-specific elements without any setup effort on your part. You no longer need to add waits and sleeps to your test. Protractor can automatically execute the next step in your test the moment the webpage finishes pending tasks, so you don’t have to worry about waiting for your test and webpage to sync. Protractor needs two files to run, a spec file and a configuration file. Open a new command line or terminal window and create a clean folder for testing.

    The warehouse's SpringBoot-based rights management system

    The warehouse's SpringBoot-based rights management system is easy to read and understand, and the interface is simple and beautiful. The core technology uses Spring, MyBatis, and Shiro without any other heavy dependencies. I have always wanted to make a background management system, and I have seen many excellent open source projects but found no suitable ones. So I started to write a background system in my spare time. So there is Zoe. She can be used for all web applications, such as website management background, website member center, CMS, CRM, OA. All front-end and back-end codes are very compact and easy to use after encapsulation, and the probability of errors is low. Also supports mobile client access. The system will continue to update some useful functions. The user is the system operator, and this function mainly completes the system user configuration. Configure the system organization (company, department, group).

    Express & Koa middlewares and Fastify & Hapi plugins for CLS-based request ID generation, batteries included. An out-of-the-box solution for adding request IDs into your logs. Check out this blog post that describes the rationale behind cls-rtracer. Automatically generates a UUID V1 value as the id for each request and stores it in AsyncLocalStorage. Optionally, if the request contains an X-Request-Id header, uses its value instead. Allows to obtain the generated request id anywhere in your routes later and use it for logging or any other purposes.

    Web app and framework offering modular conversion and encoding

    Web app and framework offering modular conversion, encoding and encryption. Translations are done client-side without any server interaction. This framework and web app aims to support a wide variety of ciphers, formats, algorithms and methods (called 'Bricks') while keeping them easily combinable. There are currently two types of Bricks: Encoders and Viewers. Encoders manipulate content by encoding or decoding in a specific way and using specific settings while Viewers allow users to access and edit the content fed into or outputted by Encoders in a certain way and format. Bricks can be arranged inside a Pipe. When the content gets edited inside a Viewer or when Brick settings get changed, the result propagates through the Pipe's Bricks in order and in both directions. Chain objects encapsulate UTF-8 text or binary-based content exchanged between Bricks.

    goober

    goober

    A less than 1KB css-in-js solution

    As the subtitle notes, this is the smallest and fullest featured css-in-js solution out there. Weighing at 1KB and once bundled it's gonna be less due to tree-shake. goober does more with less! Since the code measure less in size, it's served, read and ran quicker. goober is built on the shoulders of well-established solutions. That means the API has been paved and we need to follow it. You'll find as, forwarded, CSS, keyframes, styled and so much more. Easily access your common sizes, colors, and anything really with the use of a theme. On the server, you can easily extract the CSS for the current state with extractCss. The initial thought of goober was a CSS-in-js solution at the cost of peanuts. Hence the peanuts emoji. By using goober, you are practically getting back space in size to build more of the needed features.

    jsdom

    jsdom

    JavaScript implementation of various web standards, for use with Node

    jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. The latest versions of jsdom require Node.js v10 or newer. To use jsdom, you will primarily use the JSDOM constructor, which is a named export of the jsdom main module. Pass the constructor a string. The resulting object is an instance of the JSDOM class, which contains a number of useful properties and methods besides window. In general, it can be used to act on the jsdom from the "outside," doing things that are not possible with the normal DOM APIs. For simple cases, where you don't need any of this functionality, we recommend a coding pattern.
