Buffalo 1.0: Rapid Web Development in Go — Buffalo has been around for many years, and while 1.0 isn’t a big, feature packed release (indeed, no new code since 0.18.9), it’s a key milestone so congratulations to the team! If you’re new to Buffalo, there are plenty of tutorials to get you going.

GopherJS: A Go to JavaScript Transpiler — It’s been a few years since we featured GopherJS but the latest beta brings it up to Go 1.18 (though without generics for now, alas) and ES6/ES2015 standards. There’s an online playground if you want to have a quick play.


Meet GoLand 2022.2 — This version offers new features for generics and go․work. We’ve added support for fuzz tests, and SQL statements are now automatically detected. GoLand also now supports WebSocket connections and can send GraphQL queries out of the box.
