Getting started on Go Lang with Slack

It is a Republic Day today here in India, January 26th and a national holiday. During one of our random morning conversations with Manoj. Hashicorp cropped up into the topic and that quickly escalated to "Go Lang".

Go Lang has been on my radar for quite some time. I wanted to get started with the language. It's my personal thing that lots of new tools and products are being built on Go and I'm still stuck with JVM. After all moving to Devops demands some change in how I operate right? 😃

While getting started with a new programming language, I always write a simple tool using it and open source it. I wrote a Live NSE Stock information fetcher while I was learning NodeJS 4 years ago and a uClassify Scala client while I was getting started with Scala 3 years ago.

On the similar lines, introducing Slack webhooks library in Go. It's similar to it's Java counterpart, it helps you post messages to slack using a Incoming Webhook url.

Usage - https://github.com/ashwanthkumar/slack-go-webhook/blob/master/README.md

This is still my first Go lang code so any kind of feedback will be helpful.

Slack Java Webhook

GoCD recently added support for notification extension point. I've started building slack notification plugin (its a WIP here). As part of that I wrote a Java client for Slack Webhooks. Although I found a java library here, which said it was published but I couldn't find it anywhere on sonatype / maven central. I can't even publish it, so I took that as an inspiration and wrote my own implementation on https://github.com/ashwanthkumar/slack-java-webhook.

Usage

new Slack(webhookUrl)
    .icon(":smiling_imp:") // Ref - http://www.emoji-cheat-sheet.com/
    .sendToUser("slackbot")
    .displayName("slack-java-client")
    .push(new SlackMessage("Text from my ").bold("Slack-Java-Client"));

It gets posted in the slack channel like below
