Topic: Go

GraphQL has been a buzzword for a while now. I immediately fell in love with it when GitHub announced a public GraphQL API. A few weeks ago AWS introduced AppSync, a serverless GraphQL with support for custom data sources using AWS Lambda. Together with the recently introduced Go support for AWS Lambda, this is just awesome!

After attending a talk at the GitHub Universe 2016 about Hubot, I felt the need to write a little Go library to speed up my process of creating bots for Slack. With hanu you can get started with the buzzword ChatOps in seconds. The final bot will be running on Heroku using a worker dyno, but of course this works fine on your local machine as well.

After the setup of a go command line tool with Cobra it’s now time to release it to the public and publish it to Homebrew for easy installation on MacOS. Together with the steps to use AWS S3, CloudFront and SSL Certificate Manager for easy web hosting it’s a pretty neat setup for your Homebrew application formula and go binary.

Cobra is an awesome and widely used library and generator for Command Line applications written in Go. Together with goxc you can easily create a neat setup to get started with CLI interactions.

It only takes a couple of minutes to deploy a go application to a free Heroku dyno, use a custom domain name and enable free SSL using CloudFlare. If you still have some seconds left - and you will - it’s dead simple to add Prometheus metrics as well.
