Go On The Fly

Go “On The Fly”

People that know me, know that I love to fly fish and tie flies. I made up the saying โ€œTime flies when youโ€™re tying flies.โ€ It is true, just like when you are trying to solve a programming problem, time flies.

Over the past few years, we at Keyhole have utilized Docker (with assorted technologies) and have gotten up to speed on the Hyperledger blockchain framework. Something that all of these technologies have in common is the Go language. Go is the language used to implement Docker, Hyperledger, OpenShift, and many other system-level applications.

Personally, I like to peek under the hood to better understand the tools Iโ€™m using. That led me to learning about the Go language. And in my opinion, the best way to learn a language is to build something.

So, I built an application for fly tying videos. There are numerous fly tying tutorials on YouTube, so I built an application that allows them to be organized into virtual fly boxes and types.

In this blog, I will introduce you to the Go language. Weโ€™ll go over some of the key language concepts by walking through how the https://flytyerworld.com server-side API is implemented using Go.
