I recommend the Mattermost server: https://github.com/mattermost/mattermost-server https://github.com/mattermost/mattermost-server And I disagree with those that say stdlib is the best way of looking at the best Go code for two reasons: 1. A lot of times stdlib code is restricted to use only backward compatible code with old API contracts, some parts are neat but others are unwieldy. It's a hit or miss. 2. Library code is different to application code. You can't get as much variety in style, abstractions, design patterns in stdlib as you can in a real world application. I reckon it's important to read to get a whiff of succinct Go code, very good at learning protocols (like OAuth, Http etc) if you're interested, but won't be hugely helpful in building a CRUD app.
