This month Twitch took a swing at hosting a Developer Day ahead of its annual TwitchCon event, and the fruits of that labor are now available online for curious devs to peruse at their leisure.
Specifically, there are now a bunch of videos and slides archived online (on the company's dev-focused channel) that feature Twitch staffers digging into (and promoting) a bunch of the platform's features that might be of interest to devs.
For example, there's a talk about the nuts and bolts of selling games and items via Twitch Commerce, a presentation on using Twitch to build up your community, and a guide to using the new Extensions toolset to build a game that can be interactive when streamed on Twitch.
For a bit more context on how Twitch is trying to pitch itself to game devs, check out this talk on the topic that Twitch dev relations chief Kathy Astromoff gave at GDC 2016.
