This post walks through how I created the [Go Templates Playground][playground]. It pulls Go template rendering capabilities directly into your browser with WebAssembly (Wasm). I was motivated to this after recently seeing the utility of other similar environments out there for different programming languages1. The Go template language has relatively wide adoption in projects like Helm and Hugo, which this tool can be used to prototype and experiment for. I’ve also been interested in incorporating Wasm into a deployed project, and this was a great opportunity for it, as well as chance to play with alternate approaches to help bring what are traditionally backend languages to the browser.
