Since the day I started using Slack at my last company I marveled at the composition of the application and how it ran both on Web and native desktop environments using a native wrapper around Web. I spent a little time trying to reverse-engineer the stack to understand what it was building on top of, deducing only it wasn't using NW.js. So, what then? I queried colleagues and Twitterverse only to come up empty-handed…
And then, as things sometimes are in the world of discovery, I stumbled across a repo starred by @sindresorhus and there it was: Electron.
Of course the search would've been much easier had I know about StackShare at the time when Slack posted their tech stack.
