Radium Grid: A React Grid System Injected With The Power of Radium

Check out Radium Grid on GitHub! After spending my formative frontend years implementing layouts with the CSS grid systems from both Bootstrap and Foundation, I developed a clear understanding of the strengths and weaknesses of both. Later, grid systems like Jeet solved many of the pain points of...


Why we chose MobX over Redux for Spectacle Editor

For Spectacle Editor, our current collaboration with Plot.ly, we decided to use MobX to handle application state instead of Redux. Redux is an amazing framework, and here at Formidable we continue to use it on new and existing client projects with great results. In part, the decision to use MobX was...


Announcing Spectacle Editor, a work in progress

Spectacle Editor is a collaboration between Plotly and Formidable. The end result will be the first open source presentation tool with deep Plotly integration. Building on top of everyone’s favorite React slide show framework, Spectacle, we’re inviting the community to witness and participate in...

React Inline Styles and the Future of CSS

Writing and maintaining CSS for large applications (and large teams) can be challenging. Teams often have trouble with brittle selectors, naming collisions, specificity, and pile-ups of dead code. After seeing these issues first-hand on large projects, we built Radium: a JavaScript library for...

When I write CSS it takes me longer than it should, and often ends with someone more talented indulgently explaining how I could have avoided making such a mess of things. So, while I can literally do the thing, I can��...


Unit testing React Native with Mocha and Enzyme

Working in React Native has been an amazing experience. Coming from React, the workflow has been nearly frictionless. There has, however, been one question lingering: How the hell am I going to test this? Specifically, what is the best way to unit test my component logic? Testing JavaScript that...


First impressions with the web’s latest presentation tool: Spectacle

Spectacle, if you haven’t seen it, is another in a long line of HTML presentation tools, but this one has rocketed into popularity (which isn’t exactly common for something like presentation tooling). Since I had heard it has a few neat tricks up its sleeve, and as a born and bred skeptic, I...


The Only Correct Script Loader Ever Made

A team here at Formidable was recently tasked with choosing a JavaScript loader in order to dynamically load scripts in the browser. After exhaustively testing every script loader we could think of, we found them all to fail in at least one way. With a complete test suite in hand, we set out to...


Using React is a Business Decision, Not a Technology Choice

Preamble: React has become very popular among developers and there are lots of resources that speak to its technical merits. However, migrating to (or choosing) a new framework ultimately comes down to selling it to everybody at the table — including non-developers. There are very few...
