Intro – Rapid Software Development in the Modern World with Golang
(Feel free to skip to the tutorial)
This post is the first in a planned series about rapid software development in the modern world.
Elad was talking to me about how non-trivial it has become to choose a stack in today’s world. And let’s say you’ve chosen your tools – only the most experienced developers know how to set up CI, testing, deployment, instrumentation, monitoring, security, etc. correctly. A lot of Ops knowledge is involved in even getting things initially running.
We’ve been dealing a lot with rapid developer onboarding at Otomato software. But what got us started diving deeper into this – was my conversation with Elad Meidar a few months back.
Our current goal is to take that knowledge we’ve accumulated and make it available as a service. And while we’re doing that – we’re exploring the currently available tooling.
Buffalo is a framework (or a tool) for rapid web development in Go. Cloud Native DevOps folks (and that’s what we are at Otomato) have a soft spot for Golang, so I’m starting this series with Buffalo.
The official getting started section of Buffalo documentation is excellent but as I ran through it, I noticed it lacks some operational details that I’m planning on exposing. Again there’s Ops knowledge lurking in the dark!
Reasonably naturally, one would need to install Golang.
On a Mac:
brew install golang
sudo apt update && sudo apt install golang
Note: on older systems (such as Ubuntu 20.04) you’ll get a very old version of Go (1.13) by default when installing with
apt. So instead – choose the download-n-extract option here.
For additional installation options, go here
On a Mac:
brew install nodejs
sudo apt update sudo apt install nodejs npm
Buffalo makes quite a few educated assumptions when generating your project. One of them is that you’ll want to wrap your app in a container. You can, of course, opt-out, but why? So if you’re going with the flow and enjoying the benefits of containerization – you probably already have Docker installed. If not – please do so now – we’ll need it further along the tutorial.
On a Mac:
brew install gobuffalo/tap/buffalo
wget https://github.com/gobuffalo/cli/releases/download/v0.18.8/buffalo_0.18.8_Linux_x86_64.tar.gz tar -xvzf buffalo_0.18.8_Linux_x86_64.tar.gz sudo mv buffalo /usr/local/bin/buffalo
Buffalo has a project scaffolding feature that allows us to generate a new app complete with:
- a local git repository
- a backend api
- a db integration
- a frontend
- a Dockerfile
- a CI pipeline.
