    SlickGrid

    SlickGrid

    A lightning fast JavaScript grid/spreadsheet

    Quite simply, SlickGrid is a JavaScript grid/spreadsheet component. It is an advanced component and is going to be a bit more difficult to learn and configure, but once you realize its full potential, it will blow your mind! SlickGrid utilizes virtual rendering to enable you to easily work with hundreds of thousands of items without any drop in performance. In fact, there is no difference in performance between working with a grid with 10 rows versus a 100’000 rows. This is achieved through virtual rendering where only what’s visible on the screen plus a small buffer is rendered. As the user scrolls, DOM nodes are continuously being created and removed. These operations are highly tuned to provide optimal performance under all browsers. The grid also adapts to the direction and speed of scroll to minimize the number of rows that need to be swapped out and to dynamically switch between synchronous and asynchronous rendering.

    stylefmt

    stylefmt

    stylefmt is a tool that automatically formats stylesheets

    stylefmt is a tool that automatically formats CSS according to stylelint rules. stylefmt'd code is easier to write. Never worry about minor formatting concerns while hacking away. Easier to read, when all code looks the same you need not mentally convert others' formatting style into something you can understand. Easier to maintain, mechanical changes to the source don't cause unrelated changes to the file's formatting; diffs show only the real changes. Uncontroversial, never have a debate about spacing or brace position ever again! If you are using stylefmt with stylelint configuration to format according to its rules, you can now use stylelint's, fix option (from v7.11.0) to auto fix. On the other hand, prettier supports to format not only JavaScript but also CSS, SCSS, and Less code.
