What is Compass?

The compass core framework is a design-agnostic framework that provides common code that would otherwise be duplicated across other frameworks and extensions.

What is Less?

Less is a CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins, functions and many other techniques that allow you to make CSS that is more maintainable, themable and extendable.

What is Sass?

Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.

        ReactQL is a React + GraphQL front-end starter kit. #JSX is a natural way to think about building UI, and it renders to pure #HTML in the browser and on the server, making it trivial to build server-rendered Single Page Apps. GraphQL via Apollo was chosen for the data layer; #GraphQL makes it simple to request just the data your app needs, and #Apollo takes care of communicating with your API (written in any language; doesn't have to be JavaScript!), caching, and rendering to #React.

        ReactQL is written in TypeScript to provide full types/Intellisense, and pick up hard-to-diagnose goofs that might later show up at runtime. React makes heavy use of Webpack 4 to handle transforming your code to an optimised client-side bundle, and in throws back just enough code needed for the initial render, while seamlessly handling import statements asynchronously as needed, making the payload your user downloads ultimately much smaller than trying to do it by hand.

        React Helmet was chosen to handle <head> content, because it works universally, making it easy to throw back the correct <title> and other tags on the initial render, as well as inject new tags for subsequent client-side views.

        styled-components, Sass, Less and PostCSS were added to give developers a choice of whether to build styles purely in React / JavaScript, or whether to defer to a #css #preprocessor. This is especially useful for interop with UI frameworks like Bootstrap, Semantic UI, Foundation, etc - ReactQL lets you mix and match #css and renders to both a static .css file during bundling as well as generates per-page <style> tags when using #StyledComponents.

        React Router handles routing, because it works both on the server and in the client. ReactQL customises it further by capturing non-200 responses on the server, redirecting or throwing back custom 404 pages as needed.

        Koa is the web server that handles all incoming HTTP requests, because it's fast (TTFB < 5ms, even after fully rendering React), and its natively #async, making it easy to async/await inside routes and middleware.

        We use Sass because I invented it! No, that's not a joke at all! Well, let me explain. So, we used Sass before I started at Rent the Runway because it's the de-facto industry standard for pre-compiled and pre-processed CSS. We do also use PostCSS for stuff like vendor prefixing and various transformations, but Sass (specifically SCSS) is the main developer-focused language for describing our styling. Some internal apps use styled-components and @Aphrodite, but our main website is allllll Sassy. Oh, but the non-joking part is the inventing part. /shrug

        Absolutely fantastic, not only does it allow for modularity but it is armed with the most useful features like colour operations and nested styles to make you achive more by writing LESS.

        It was a little awkward building BS3 with LESS, and the rest of the site with SCSS, but it works. SCSS made building the UI elements (ink/flip buttons, img navs, etc) a breeze. It also drives the mobile menu open/close transitions - that would have been much too much with vanilla css.

        Sass helps us write better stylesheets. One major improvement over CSS that we use a lot is variables - it allows for much easier theming to quickly change brand colors for new instances of the xCoLab.

        When you realise that countless lines of CSS codes could be made countable. And off course, a wonderful and cool way to use the logic behind variables and nesting. Simply love it.

        Sass is used as a part of Woltlab Suite Core, which offers to submit/configure own styles via the injection of own Sass-CSS. So we exclusively rely on Sass for our CSS needs.

        CSS is a mess. There, we said it. Sass, on the other hand takes CSS and makes it pretty, easy to work with and has stuff like variables which make things seriously awesome.

        Customise the UIkit Front-End Framework, because of that is used to create the application CSS. I prefer SASS but is equivalent.

        Sass library that was originally used on the current JourneyMaker app. We've been slowly removing it from the front end.

        CSS Preprocessor, used primarily for variables to ensure brand colour continuity.

        We use Less to organize our CSS code with imports, variables, mixins, and more.
