Following up on designing delightful dark themes, I wanted to share this post from Kyle Stetz on the frontend engineering strategy for building Slack’s dark mode on desktop.

As is usually the case with large codebases, finding an implementation that works is only half the battle; gracefully changing infrastructural code and educating engineers on how to use new tools accounts for much of what we do when working on new capabilities of the product. Working in a large engineering organization — especially within a rapidly growing company — means that every change needs to consider the momentum and roadmaps of many other teams. The overarching question for this project was: how can we build sustainable and maintainable support for themes?
