scrape-it
A Node.js scraper for humans
scrape-it is a Node.js library for converting web pages and HTML documents into structured JavaScript objects. Developers describe the desired output through a declarative schema based on CSS selectors. Fields can extract text, raw HTML, element attributes, repeated items, and nested lists. Conversion functions can transform captured values into dates, numbers, or other application-specific types. The library supports promises, async and await workflows, and callback-based usage. It can request ordinary pages directly or parse HTML obtained from local files and headless browsers. Scrape It does not execute client-side JavaScript itself, so dynamic sites may require an API endpoint or a separate browser automation tool. -

serverless-chrome
Run headless Chrome/Chromium on AWS Lambda
Serverless Chrome contains everything you need to get started running headless Chrome on AWS Lambda (possibly Azure and GCP Functions soon). The aim of this project is to provide the scaffolding for using Headless Chrome during a serverless function invocation. Serverless Chrome takes care of building and bundling the Chrome binaries and making sure Chrome is running when your serverless function executes. In addition, this project also provides a few example services for common patterns (e.g. taking a screenshot of a page, printing to PDF, some scraping, etc.). Why? Because it's neat. It also opens up interesting possibilities for using the Chrome DevTools Protocol (and tools like Chromeless or Puppeteer) in serverless architectures and doing testing/CI, web-scraping, pre-rendering, etc. You must configure your AWS credentials either by defining AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environmental variables, or using an AWS profile. -

sigma.js
A JavaScript library dedicated to graph drawing
Sigma is a JavaScript library dedicated to graph drawing. It makes easy to publish networks on Web pages, and allows developers to integrate network exploration in rich Web applications. Sigma provides a lot of built-in features, such as Canvas and WebGL renderers or mouse and touch support, to make networks manipulation on Web pages smooth and fast for the user. The default configuration of sigma deals with mouse and touch support, refreshing and rescaling when the container's size changes, rendering on WebGL if the browser supports it and Canvas else, recentering the graph and adapting the nodes and edges sizes to the screen. Sigma provides a lot of different settings to make it easy to customize how to draw and interact with networks. And you can also directly add your own functions to your scripts to render nodes and edges the exact way you want. Sigma is a rendering engine, and it is up to you to add all the interactivity you want. -

simple-git-hooks
A simple git hooks manager for small projects
A simple git hooks manager for small projects. A git hook is a command or script that is going to be run every time you perform a git action, like git commit or git push. If the execution of a git hook fails, then the git action aborts. For example, if you want to run linter on every commit to ensure code quality in your project, then you can create a pre-commit hook that would call npx lint-staged. Check out lint-staged. It works really well with simple-git-hooks. You can look up about git hooks on the Pro Git book. simple-git-hooks works well for small-sized projects when you need quickly set up hooks and forget about it. However, this package requires you to manually apply the changes to git hooks. If you update them often, this is probably not the best choice. Also, this package allows you to set only one command per git hook. -

spider_collection
Collection of Python web scraping scripts for data extraction tasks
spider_collection is a collection of Python web crawler scripts created primarily for experimentation, learning, and practical scraping tasks. spider_collection gathers multiple independent spiders designed to collect data from different platforms and services, demonstrating a variety of scraping techniques and workflows. These crawlers make use of common Python scraping tools such as requests, parsel, BeautifulSoup, and the Scrapy framework to extract structured information from web pages. Several scripts also incorporate multi-threading and proxy usage to improve scraping efficiency and help avoid common anti-scraping limitations. In addition to raw data collection, some spiders include basic data processing and analysis using tools such as pandas and simple visualization with matplotlib. It also contains examples of proxy pool integration and encapsulation to support more reliable crawling when working with sites that enforce request limits. -

stylus
Expressive, robust, feature-rich CSS language built for nodejs
Stylus is a revolutionary new language, providing an efficient, dynamic, and expressive way to generate CSS. Supporting both an indented syntax and regular CSS style. Installing Stylus is very easy once you have Node.js. So get the binaries for your platform and make sure that they also include npm, Node’s package manager. Stylus features powerful in-language function definitions. Function definitions appear identical to mixins; however, functions may return a value. Optional arguments may default to a given expression. With Stylus we may even default arguments to earlier arguments! Stylus is an innovative stylesheet language that compiles down to CSS. Inspired by SASS, Stylus is built with node.js and capable of running in the browser. Stylus is “pythonic” (i.e. indentation-based). Whitespace is significant, so we substitute { and } with an indent, and an outdent. Stylus, just like CSS, allows you to define properties for several selectors at once through comma separation. -

tv.js
Apple TV for Torrent Streaming in JS (Node/Chrome)
tv.js is a JavaScript smart TV experiment for streaming movies through a TV-style interface. It was built as a 24-hour hackathon project and is designed to run as a server with a browser-based front end. The app can run on a Raspberry Pi connected to a television through HDMI. Its interface can be controlled from a smartphone, so users do not need a keyboard or mouse in the living room. The project originally combined movie lookup, torrent search, BitTorrent streaming, and video conversion into one prototype. Because it deals with torrent-based media access, it should only be used with content the user is legally allowed to stream. -

unfetch
Bare minimum 500b fetch polyfill
Tiny 500b fetch "barely-polyfill". With a module bundler like rollup or webpack, you can import unfetch to use in your code without modifying any globals. While one of Unfetch's goals is to provide a familiar interface, its API may differ from other fetch polyfills/ponyfills. One of the key differences is that Unfetch focuses on implementing the fetch() API, while offering minimal (yet functional) support to the other sections of the Fetch spec, like the Headers class or the Response class. Uses simple arrays instead of iterables, since arrays are iterables. No streaming, just Promisifies existing XMLHttpRequest response bodies. Use in Node.JS is handled by isomorphic-unfetch. -

web4
Web4 is a new way to distribute decentralized apps
Web4 is a new way to distribute decentralized apps. Deploy a single WASM smart contract to deploy the whole web app. You only need to deploy a single smart contract using WebAssembly to host your app's HTTP backend, static resources, and blockchain logic. There is an HTTP gateway to NEAR blockchain which allows smart contract to handle arbitrary GET requests. Every smart contract on NEAR also gets a corresponding API endpoint which can be accessed through regular HTTP requests. You can load any required data in web4_get by returning list of URLs to preload in preloadUrls field. Note that both JSON and form data are supported. When transaction is processed by server user gets redirected to wallet for signing this transaction.
