CSS Blocks vs Emotion: What are the differences?

CSS Blocks: A component-oriented CSS authoring system by LinkedIn. By combining an opinionated authoring system, build-time analysis and rewriting of templates, and a new type of CSS optimizer, css-blocks breathes new power and ease of use into the technologies and best practices that stylesheet developers already know and love; Emotion: The Next Generation of CSS in JS. Emotion is a performant and flexible CSS-in-JS library. Building on many other CSS-in-JS libraries, it allows you to style apps quickly with string or object styles. It has predictable composition to avoid specificity issues with CSS. With source maps and labels, Emotion has a great developer experience and great performance with heavy caching in production.

CSS Blocks and Emotion can be categorized as "JavaScript Framework Components" tools.

          When we rebooted our front-end stack earlier this year, we wanted to have a consolidated and friendly developer experience. Up to that point we were using Sass and BEM. There was a mix of HAML views, React components and Angular. Since our ongoing development was going to be exclusively in React, we wanted to shift to an inline styling library so the "wall of classnames" could be eliminated. The ever-shifting landscape of inline CSS libraries for React is sometimes difficult to navigate.

          We decided to go with Glamorous for a few reasons:

          1) Previous team experience with this library 2) We can write our styles in plain JavaScript (which brings many benefits) 3) It supports server-side rendering 4) It has great composition patterns

          As you may or may not know, Glamorous has ceased active development and been mostly superseded by Emotion. We are planning to migrate to either Emotion or @styled-components in the near future, and I'll write another Stack Decision when we get there!

          For Stack Decisions I needed to add Markdown in the decision composer to give our users access to some general styling when writing their decisions. We used React & GraphQL on the #Frontend and Ruby & GraphQL on the backend.

          Instead of using Showdown or another tool, We decided to parse the Markdown on the backend so we had more control over what we wanted to render in Markdown because we didn't want to enable all Markdown options, we also wanted to limit any malicious code or images to be embedded into the decisions and Markdown was a fairly large to import into our component so it was going to add a lot of kilobytes that we didn't need.

          We also needed to style how the markdown looked, we are currently using Glamorous so I used that but we are planning to update this to Emotion at some stage as it has a fairly easy upgrade path rather than switching over to styled-components or one of the other cssInJs alternatives.

          Also we used React-Mentions for tagging tools and topics in the decisions. Typing @ will let you tag a tool, and typing # will allow you to tag a topic.

          The Markdown options that we chose to support are tags: a, code, u, b, em, pre, ul, ol, li.

          If there are anymore tags you'd love to see added in the composer leave me a comment below and we will look into adding them.

          We are in the process of adopting Next.js as our React framework and using Storybook to help build our React components in isolation. This new part of our frontend is written in TypeScript, and we use Emotion for CSS/styling. For delivering data, we use GraphQL and Apollo. Jest, Percy, and Cypress are used for testing.
