Vizzu
Library for animated data visualizations and data stories
Vizzu is a free, open-source Javascript/C++ library utilizing a generic dataviz engine that generates many types of charts and seamlessly animates between them. It can be used to create static charts but more importantly, it is designed for building animated data stories and interactive explorers as Vizzu enables showing different perspectives of the data that the viewers can easily follow due to the animation. Create a placeholder element that will contain the rendered chart. The Vizzu constructor has to load Vizzu's WebAssembly module asynchronously to prevent blocking the whole page. Because of this, any method except animate() will throw an exception while the library is not initialized. There is an initializing promise in the Vizzu class, which will resolve when initialization is finished. You can call all methods after this promise is resolved. -

create-dmg
Create a good-looking DMG for your macOS app in seconds
Imagine you have finished a macOS app, exported it from Xcode, and now want to distribute it to users. The most common way of distributing an app outside the Mac App Store is by putting it in a .dmg file. These are hard to create, especially good-looking ones. You can either pay for a GUI app where you have to customize an existing design or you can run some homebrewed Bash script and you still have to design it. This tool does everything for you, so you can play with your cat instead. The DMG detects the minimum runtime of the app, and uses ULFO (macOS 10.11 or later) or UDZO as appropriate. The resulting image has the filename App Name 0.0.0.dmg, for example, Lungo 1.0.0.dmg. It will try to code sign the DMG, but the DMG is still created and fine even if the code signing fails, for example if you don't have a developer certificate. -

cross-env
Cross platform setting of environment scripts
Run scripts that set and use environment variables across platforms. Cross-env still works well, but is in maintenance mode. No new features will be added, only serious and common-case bugs will be fixed, and it will only be kept up-to-date with Node.js over time. Most Windows command prompts will choke when you set environment variables with NODE_ENV=production like that. (The exception is Bash on Windows, which uses native Bash.) Similarly, there's a difference in how windows and POSIX commands utilize environment variables. -

deck.gl
WebGL2 powered visualization framework
deck.gl is designed to simplify high-performance, WebGL-based visualization of large data sets. Users can quickly get impressive visual results with minimal effort by composing existing layers, or leveraging deck.gl's extensible architecture to address customer needs. deck.gl maps data (usually an array of JSON objects) into a stack of visual layers - e.g. icons, polygons, texts; and look at them with views: e.g. map, first-person, orthographic. deck.gl handles a number of challenges out of the box. Deck.gl is designed to be highly customizable. All layers come with flexible APIs to allow programmatic control of each aspect of the rendering. All core classes such are easily extendable by the users to address custom use cases. deck.gl is part of vis.gl, an OpenJS Foundation project.

eslint-plugin-import
ESLint plugin with rules that help validate proper imports.
This plugin intends to support linting of ES2015+ (ES6+) import/export syntax, and prevent issues with misspelling of file paths and import names. All the goodness that the ES2015+ static module syntax intends to provide, is marked up in your editor. The maintainers of eslint-plugin-import and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open-source dependencies you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use. With the advent of module bundlers and the current state of modules and module syntax specs, it's not always obvious where import x from 'module' should look to find the file behind module. Up through v0.10ish, this plugin has directly used substack's resolve plugin, which implements Node's import behavior. This works pretty well in most cases. -

eslint-plugin-jsdoc
JSDoc specific linting rules for ESLint
JSDoc specific linting rules for ESLint. Install ESLint either locally or globally. Rules may, as per the ESLint user guide, have their own individual options. In eslint-plugin-jsdoc, a few options, such as, exemptedBy and contexts, may be used across different rules. eslint-plugin-jsdoc options, if present, are generally in the form of an object supplied as the second argument in an array after the error level (any exceptions to this format are explained within that rule's docs). One can use minLines and maxLines to indicate how many line breaks (if any) will be checked to find a jsdoc comment block before the given code block. These settings default to 0 and 1 respectively. In conjunction with the require-jsdoc rule, these settings can be enforced so as to report problems if a jsdoc block is not found within the specified boundaries. The settings are also used in the fixer to determine how many line breaks to add when a block is missing. -

h265web.js
A HEVC/H.265 Web Player
h265web.js is a WebAssembly-powered video decoding library designed to enable playback and processing of H.265/HEVC video streams directly in web browsers without relying on native browser codec support. It provides a low-level decoding API that allows developers to build custom video players capable of handling raw H.265 streams, which are typically not widely supported natively in browsers. The project includes components for parsing H.265 bitstreams into NAL units and decoding them into raw YUV frames that can then be rendered onto a canvas or processed further. Its architecture separates parsing, decoding, and rendering, giving developers fine-grained control over how video data is handled and displayed. The system is designed to work with streaming data, allowing incremental feeding of video chunks and real-time decoding, which is useful for surveillance, streaming platforms, and custom media pipelines. -

hiproxy
hiproxy is a lightweight proxy tool for Front-End developers
hiproxy is a lightweight web proxy tool based on Node.js. The primary purpose of hiproxy is to solve the problem of host management and reverse proxy needs of developers. For example, if you are working as a team and each of the developers in the team need a different proxy setting, you will no longer need to modify your hosts file or use a web server like Nginx as a reverse proxy. hiproxy extends the syntax of hosts file to support port numbers. Besides, hiproxy also supports configuration through a syntax similar to the Nginx configuration file. To develop your web projects in a local development environment, you’ll have to run a back-end server (such as a Node.js express application, or a Java SpringBoot application). As a front-end developer, you might not be familiar with the back-end technology stack, simply setting up the development environment can consume a lot of your time. -

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. -
