A Tasty Treats NEWSLETTER for Web Developers

Issue #55:

First up, a warm welcome to Niki Brandner, the newest member of the Syntax team! She’s joining us as a Senior Podcast Producer — and we’re stoked to have her on board.

Gear up for a long one — but trust us, it’s stacked. We'll skip the bullets, dive on in.

BIG NEWS

Open AI Launched a few new products yesterday at their Dev Day.

Some interesting ones are ChatKit - a sort of boilerplate for building agentic chat experiences.

They also launched their Apps SDK” - which gives the ability to add custom apps into ChatGPT with the MCP protocol. They have used the MCP resource spec to include registering UI widgets - so not only will your app return MCP data, it can also return components which look like they can be written in Vanilla JS or React.
