    Draft.js

    Draft.js

    React framework for building text editors

    Draft.js is a framework for building rich text editors in React, powered by an immutable model and abstracting over cross-browser differences. Draft.js allows you to build any type of rich text input, whether you're only looking to support a few inline text styles or building a complex text editor for composing long-form articles. We provide the building blocks to enable the creation of a broad variety of rich text composition experiences, from basic text styles to embedded media. Draft.js fits seamlessly into React applications, abstracting away the details of rendering, selection, and input behavior with a familiar declarative API. The Draft.js model is built with immutable-js, offering an API with functional state updates and aggressively leveraging data persistence for scalable memory usage.

    Eagle.js is a web-based slideshow framework for Vue.js. It supports animations, themes, interactive widgets (for web demos), and makes it easy to reuse components, slides and styles across presentations. Most of all, Eagle aims at offering a simple and very hackable API so you can get off the beaten tracks and craft the slideshows you really want. If you are not familiar with Vue.js you will find eagle.js harder to use than, say, Reveal.js, but on the long term eagle.js makes it easier to organize your slides and implement new ideas. Eagle.js is a vue plugin. You need to use eagle.js in your vue app's main file. New in 0.3, animate.css is now a peer dependency. User need install their own version. New in 0.5, By default eagle.js doesn't export all plugins but only core components. You have to explicitly use your widgets or plugins from now on.

    Electrode Stateless CSRF

    Electrode Stateless CSRF

    Stateless Cross-Site Request Forgery (CSRF) protection with JWT

    An electrode plugin that enables stateless CSRF protection using JWT in Electrode, Express, Hapi, or Koa 2 applications. CSRF protection is an important security feature, but in systems which don't have backend session persistence, validation is tricky. Stateless CSRF support addresses this need. CSRF attacks can be bad when a malicious script can make a request that can perform harmful operations through the user (victim)'s browser, attaching user-specific and sensitive data in the cookies. For use with XMLHttpRequest and fetch, we extend the technique by using two JWT tokens for validation. One token in the cookies and the other in the HTTP headers. Since XSS cannot set HTTP headers also, it strengthens the security further.

    Ethlint (Formerly Solium) analyzes your Solidity code for style & security issues and fixes them. Standardize Smart Contract practices across your organization. Integrate with your build system. Deploy with confidence! Solium does not strictly follow Solidity Style Guide. The practices it enforces by default are best practices for the community at large. If you’re using vim with syntastic, and prefer to use a locally installed version of Solium (rather than a global version), you can install syntastic local solium to automatically load the local version in packages that have installed their own. Solium does not strictly adhere to Solidity Style Guide. It aims to promote coding practices agreed upon by the community at large. You can specify rules or plugins to apply as command line options. If you specify one, it overrides its corresponding configuration in the soliumrc file.
