Gitako stores access tokens in your chrome extension storage (not the LocalStorage) and use them only when authenticating with GitHub. -

PostCSS
A tool for transforming CSS with JavaScript
PostCSS is a tool for transforming styles with JS plugins. These plugins can do a great number of things: transpile future CSS syntax, lint your CSS, support variables and mixins, and so much more. PostCSS works by taking a CSS file and providing an API to analyze and modify its rules (through its transformation into an Abstract Syntax Tree). The API can then be used by plugins to do a lot of useful things. With PostCSS, you can increase code readability by adding vendor prefixes to CSS rules; convert modern CSS so it's understood by more browsers; and avoid errors in your CSS via stylelint, a modern CSS linter. PostCSS currently has over 200 plugins, and is being used by industry leaders worldwide. -

You may see exact list of target browsers by running npx browserslist within this repository folder.

Conquer Of Completion
Nodejs extension host for vim & neovim, load extensions like VSCode
Configuration is required to make coc.nvim easier to work with, since it doesn't change your key-mappings or Vim options. This is done as much as possible to avoid conflict with your other plugins. Some Vim plugins could change key mappings. Please use commands like verbose imap <tab> to make sure that your keymap has taken effect. Different plug-ins of VSCode provide many configuration items, most of which are used by the server, but some are used by the client. If you do not use plug-ins, you need to make different adaptations to specific servers in the code. At present, most vim LSP plug-ins only support The configuration used by the server. Some functions require the client to do some specific extensions. For example, the jdt.ls of java requires the client to support the uri starting with jdt. When using the coc-java plug-in, users only need to install the plug-in without manual configuration. -

Reverse Image Search Anywhere
4-engine reverse image search that works on Instagram & Pinterest
Reverse Image Search Anywhere is a free, open-source (MIT) browser extension for Chrome, Firefox, Edge and Opera. Most reverse-image tools work by handing a search engine the image's URL. That breaks the moment a site hides it. Instagram and Pinterest do, and so does anything drawn to a canvas or served as a blob: or data: URL. They also make you check one engine at a time, which is the slow half of the job. This extension fixes both halves. Right-click any image and search Google Lens, Yandex, Bing Visual and TinEye, one engine or all of them at once. It also handles clipboard paste, region capture, and a face-search-first flow for finding people. Privacy: plain searches never touch our servers. Uploads happen only when you ask for them, get a link that expires after 15 minutes, and the file is deleted automatically about a day after it arrives. The source is published here so you can check that rather than take it on trust. -

BetterScroll
Inspired by iscroll, supports more features and has better performance
BetterScroll is a plugin which is aimed at solving scrolling circumstances on the mobile side (PC supported already). The core is inspired by the implementation of iscroll (opens new window), so the APIs of BetterScroll are compatible with iscroll on the whole. What's more, BetterScroll also extends some features and optimizes for performance based on iscroll. BetterScroll is implemented with plain JavaScript, which means it's dependency free. BetterScroll provides a class whose first parameter is a plain DOM object when instantiated. Certainly, BetterScroll inside would try to use querySelector to get the DOM object. In BetterScroll 2.X, we split the 1.X-coupled feature into the plugin to achieve on-demand loading and reduce the volume of the package. Therefore, @better-scroll/core only provides the most core scrolling capabilities. If you want to implement the pull-up load, pull-down refresh function, you need to use the corresponding [plugin] (/en-US/plugins). -
