Oboe.js
A streaming approach to JSON
Oboe.js is a streaming approach to JSON. Oboe.js speeds up web applications by providing parsed objects before the response completes. Oboe.js is an open source Javascript library for loading JSON using streaming, combining the convenience of DOM with the speed and fluidity of SAX. It can parse any JSON as a stream, is small enough to be a micro-library, doesn't have dependencies, and doesn't care which other libraries you need it to speak to. We can load trees larger than the available memory. Or we can instantiate classical OOP models from JSON, or completely transform your JSON while it is being read. Oboe makes it really easy to start using json from a response before the ajax request completes. Or even if it never completes. -

OnlineToolsBook
Online tool cheats, write a high-quality manual for online tools
OnlineToolsBook positions itself as a “manual/handbook” for useful online tools — collating, documenting, and explaining many web-based utilities to help users discover, understand, and effectively use them. Rather than building a single web-tool, this repository serves as a knowledge base: descriptions, guidance, and possibly examples or usage notes about a variety of online tools, organized in a way that’s meant to help “make online tools benefit humanity.” For someone who frequently resorts to ad-hoc web tools to solve tasks (text manipulation, image processing, conversion, utilities), OnlineToolsBook acts as an aggregator of “cheat sheets” or curated pointer collection rather than a specific application. The intention appears to be long-term: the repository can be updated to reflect new tools, remove broken ones, organize categories, or provide usage hints — so it becomes a living, crowd-maintained reference. -

OpenZeppelin Contracts
OpenZeppelin Contracts is a library for secure smart contracts
A library for secure smart contract development. Build on a solid foundation of community-vetted code. OpenZeppelin Contracts uses semantic versioning to communicate backward compatibility of its API and storage layout. To keep your system secure, you should always use the installed code as-is, and neither copy-paste it from online sources nor modify it yourself. The library is designed so that only the contracts and functions you use are deployed, so you don't need to worry about it needlessly increasing gas costs. Reduce the risk of vulnerabilities in your applications by using standard, tested, community-reviewed code. -

Page Monitor
capture webpage and diff the dom change with phantomjs
Page Monitor is a JavaScript webpage monitoring tool that captures a page and compares its DOM changes over time. It uses PhantomJS to render webpages and generate screenshots, which makes it useful for visual and structural change tracking. The tool can detect when elements are added, removed, edited, or restyled. It saves captures and compares them against previous versions, giving developers a way to inspect how a page changed between snapshots. It exposes a Monitor API with methods for capturing pages and manually comparing two saved states. Overall, it is a practical utility for developers who need automated webpage change detection, regression checks, or historical DOM comparison. -

Permit
An unopinionated authentication library for building Node.js APIs
This project is an unopinionated authentication library for Node.js APIs that focuses on adding an auth layer without forcing a specific framework or application style. It’s built to slot into popular server stacks like Express, Koa, Hapi, or Fastify, and it stays compatible with different API styles including REST and GraphQL. The library concentrates on the core authentication schemes many APIs need, including bearer token authentication and basic username/password credentials. It also supports pulling credentials from common request locations, prioritizing standards-based headers while allowing practical alternatives when needed. The design aims to keep authentication logic centralized and consistent, so you avoid copy-pasting auth checks across handlers and middleware. In short, it provides a small, reusable abstraction for authenticating requests that you can adapt to your project’s policies and user model. -

PhotoJShop
Photo editing JavaScript library
PhotoJShop is a JavaScript library for photo editing using the canvas and kernel convolution matrixes, aiming to reproduce the most usual filters. A demo of its capabilities can be seen in Nuophoto, a project that uses this library for all the editing. The idea is to provide a simple library to developers that will allow quick integration of photo filters to their website. After including jQuery, include photojshop.jquery.js. Once loaded you simply need to call it on a valid element. You have to ensure that the element has loaded, $(document).ready() doesn't mean images have loaded. -

Polymer
A Web Component library
Polymer is a lightweight Web Components library that lets you create encapsulated Web Components that work just like standard HTML elements. These elements can be used in building web applications and are reusable. Polymer can be particularly useful when building UI components. Instead of having to constantly rebuild components such as a specific navigation bar or button in different frameworks and for different projects, simply define this component once with Polymer, and you can use it again and again in your future projects. Because Polymer is built on top of the web standards-based Web Components APIs, custom HTML elements made from it are built totally from the platform up and are interoperable across frameworks. Polymer also works across all major browsers. -
