Replace Google CDN
A Chrome plugin: Replace Google CDN with domestic
For well-known reasons, just substituting a domain name can continue to use the front-end public library provided by Google. Likewise, referencing these resources via the scripttag will instantly speed up your website access! Many websites, especially foreign websites, use Google's CDN in order to speed up the website. But in China, due to some reasons, the world's fastest CDN has become the world's slowest. So, I wrote this plugin/extension to replace Google's CDN with a domestic one. This plugin/extension can replace the cdn resources with domestic ones. -

webpack DevServer
Serves a webpack app and updates the browser on changes
webpack-dev-server can be used to quickly develop an application. Options that are compatible with webpack-dev-middleware have a key icon next to them. This set of options is picked up by webpack-dev-server and can be used to change its behavior in various ways. When the server is started, there will be a message prior to the list of resolved modules. If you're using dev-server through the Node.js API, the options in devServer will be ignored. Pass the options as a second parameter instead: new WebpackDevServer(compiler, {...}). Be aware that when exporting multiple configurations only the devServer options for the first configuration will be taken into account and used for all the configurations in the array. HTML template is required to serve the bundle, usually it is an index.html file. Make sure that script references are added into HTML, webpack-dev-server doesn't inject them automatically. -

GhostText
Use your text editor to write in your browser
Whenever you’re writing more than a little snippet of code anywhere on the web, activate GhostText to open your preferred text editor and enjoy your own development environment. GhostText is a browser extension that connects to your editor via its own extension. Install both extensions and, if necessary, start the GhostText server in the editor’s extension. Most editor extensions are authored by third parties. You can create more extensions for your favorite editor! Refer to the protocol document. Once you have installed both browser and editor extensions, you can activate GhostText in the current browser tab by clicking its icon in the toolbar or by using a keyboard shortcut. The editor needs to be launched first. In some editors you’ll need to run the Enable GhostText command to start the server. Refer to the documentation of each extension. Sublime Text doesn’t need this step. -

IPFS Web UI
A frontend for an IPFS node
A web interface to IPFS, shipped with Kubo, and ipfs-desktop. Check on your node stats, explore the IPLD powered merkle forest, see peers around the world and manage your files, without needing to touch the CLI. When working on the code, run an ipfs daemon, the local dev server, the unit tests, and the storybook component viewer and see the results of your changes as you save files. If you need to run IPFS in a Docker container, you can still have Web UI available by exposing both the Gateway and Web UI ports. The end-to-end tests (E2E) test the full app in a headless Chromium browser. They spawn real IPFS node for HTTP API and a static HTTP server to serve the app. The purpose of those tests is not being comprehensible, but act as a quick regression and integration suite. -

Saka Key
A keyboard interface to the web
Saka Key lets you control your browser with keyboard shortcuts. It is easy to use, highly configurable and will transform how you surf the web. Put away your mouse. When the web isn't accessible, it's because people who author content don't understand the benefit of making it accessible. Saka Key leverages accessibility information to make the browsing experience better for everyone. I hope this will encourage the creation of accessible content. Keyboard shortcuts are only the beginning of this journey. Screen reading and voice commands are on the roadmap. Map keyboard keys to browser tasks like scrolling, clicking links, switching, moving, closing, muting, and refreshing tabs, zooming, and navigating pages. Keyboard shortcuts are flexible, powerful, and easy to customize. Saka Key lets you easily switch between shortcut profiles (e.g. left hand, right hand, default, Vimium), and lets you import and export your settings. -

SingleFileZ
Web Extension for Firefox/MS Edge and CLI tool
SingleFileZ is a fork of SingleFile that allows you to save a webpage as a self-extracting HTML file. This HTML file is also a valid ZIP file that contains the resources (images, fonts, stylesheets, and frames) of the saved page. This ZIP file can be unzipped on the filesystem in order, for example, to view the page in a browser that would not support pages saved with SingleFileZ. To open saved pages from the filesystem in a Chromium-based browser, SingleFileZ must be installed and the option "Allow access to file URLs" must be enabled in the details page of the extension. Otherwise, the browser must be started with the switch. To open saved pages from the filesystem in Safari, the option "Disable Local File Restrictions" must be selected in the "Develop" menu. SingleFileZ is available on Firefox, Chrome and Microsoft Edge. You can save web pages to HTML from the command line interface. -

Bowser
Bowser is a browser detector
A small, fast and rich-API browser/platform/engine detector for both browser and node. The library is made to help to detect what browser your user has and gives you a convenient API to filter the users somehow depending on their browsers. Version 2.0 has drastically changed the API. All available methods are on the docs page. Often we need to pick users' browser properties such as the name, the version, the rendering engine and so on. You could want to filter some particular browsers to provide any special support for them or make any workarounds. Settings for any particular OS or platform has more priority and redefines settings of standalone browsers. Thus, you can define OS or platform-specific rules and they will have more priority in the end. More of API and possibilities you will find in the docs folder. -

Masonry
A cascading grid layout plugin
Masonry is a JavaScript grid layout library. It works by placing elements in optimal position based on available vertical space, sort of like a mason fitting stones in a wall. You’ve probably seen it in use all over the Internet. All sizing and styling of items is handled by your own CSS. tem sizes can be set with percentages for responsive layouts. With the masonry layout mode, set percentage-width columnWidth with element sizing. Set percentPosition: true so item positions are likewise set with percentages to reduce adjustment transitions on window resize. Unloaded images can throw off Masonry layouts and cause item elements to overlap. imagesLoaded resolves this issue. imagesLoaded is a separate script you can download at imagesloaded.desandro.com. Or, initialize Masonry after all images have been loaded. -

It checks the GitHub Notifications API every minute. Supports GitHub Enterprise and an option to only show the unread count for issues you're participating in.

The first time you click on the extension icon, it will ask you for access to browser tabs. We need this to know if there is already an opened GitHub notifications page and switch to it if so. If you want to receive desktop notifications, you can enable them on the extension options page. You will then be asked for the notification's permission. -

jqGrid
jQuery grid plugin
jqGrid is an Ajax-enabled JavaScript control that provides solutions for representing and manipulating tabular data on the web. Since the grid is a client-side solution, loading data dynamically through Ajax callbacks, it can be integrated with any server-side technology, including PHP, ASP, Java Servlets, JSP, ColdFusion, and Perl. Improve the maxGridHeigh method. Add a third parameter to indicate the minimum height at which the method run. jqGrid uses a jQuery JavaScript Library and is written as a plug-in for that package. JqGrid was developed by Tony Tomov at Trirand Inc., a software development firm based in Sofia. Trirand specializes in the development of web components and embraces free and open standards like jQuery, ThemeRoller, & jQuery UI. Tony got the idea for jqGrid when he needed an easy way to represent database information in a project. The first requirement was speed and the second, was independence from server-side technology and the database backend. -

nightTab
A neutral new tab page accented with a chosen colour
A neutral new tab page accented with a chosen color. Customize the layout, style, background and bookmarks with nightTab. Make the browser start page dark (or light, or anything in between). Do not access user information. This means nightTab will not request browser permissions. Aim to make everything on the user interface, within reason, customizable. Aim to make the user experience easy while supporting the above. Keep nightTab open source. Sharing the look and feel of one Bookmark to another can be achieved when editing a single Bookmark. The Bookmark edit modal has three options to copy settings to other Bookmarks. These checkboxes can be found at the bottom of the Visual & Name, Layout and Theme tab. Development and testing is only conducted on Chrome and Firefox. The performance and reliability of nightTab on other browsers is out of the scope of this project. -

organice
An implementation of Org mode without the dependency of Emacs
organice is an implementation of Org mode without the dependency of Emacs. It is built for mobile and desktop browsers and syncs with Dropbox, GitLab, and WebDAV. At 200ok, we run an instance of organice at https://organice.200ok.ch, which is open for anyone to use! organice does not have a back-end (it’s just a front-end application, which uses different back-end storage providers). We don’t store any kind of data on our servers - we also don’t use analytics on organice.200ok.ch. Emacs is great, but it’s desktop software. For users who want to access or edit their Org mode files whilst on the go, organice is a great choice. organice is a web application. You can use it from any browser. On iOS and Android, you can install organice to your homescreen. When started from there, it will run in full-screen as a Progressive Web Application (PWA) which will add offline capabilities (see chapters progressive web app and offline support). -
