The Darker Corners of Go — A long, long list of lessons learned about Go aimed at new to intermediate gophers (including experienced developers coming from other languages). This is a trove of things that will give you a deeper understanding of Go. 50 Shades of Go is another article in a similar vein we first linked six years ago that you may also find interesting.

Practical Go Lessons: An Online Go Book — This is a neat project. An online book (free, but there are paid PDF and paper copy versions) that covers the essentials of Go in an accessible way. Releasing it on Hacker News, the author said this is the result of over two years of writing and includes cute illustrations by his spouse.

gofakeit is a library for generating contextual random data from Go, so if you need to create job titles, names, currencies, beer names, or more, it will have the right function for you.

It's created by Brian Voelker, a senior full stack software engineer at Fluidpay, and we caught up to ask him a few questions about the project:

Do you use gofakeit in any of your own projects? If so, how?

I have used Gofakeit on practically all my own projects and company projects. It's a great way of seeding databases with information that better represents what you expect to see with tests and front end development.

What was your favourite category of data to implement?

My favorite implementation has been generating data for struct fields. Gofakeit uses a lookup system to help struct tags find the function to call to associate to the data they want to generate. It's been a pretty unique feature that can be extended upon if the user has their own data they want to generate for struct tags.

Are you keen for people to extend the amount of data in the project?

If people have data they want to add, most of the time I would be willing to add them. Otherwise, due to the way Gofakeit is set up, they have various options to utilize their own data set within Gofakeit.

What are the future plans for Gofakeit?

I'm working on a public API that can be accessed for various usages like a Chrome Extension to fill out forms. I also want to implement a service that developers can use to mimic an API service with random data.
