When I want to learn something new. It is much easier for me to make something out of it. Probably because my learning type is kinestetic, must involve physical muscle. In the case of learning coding, muscle involved is finger muscle while typing the code. Coding is not typing, but still … typing is involved … for now.

So I decided to learn Go programming language. Intrigued by its well-known good performance, and also its built-in async. And also, which is another big reason, being bored by messy javascript on nodejs.

So before I was able to code in Golang, of-course I need to learn it a bit first, which involved reading. There are my reading list for Golang:

  1. Golang Documentation
  2. A Tour of Go
  3. Writing Web Applications in Go
  4. Building Web Apps with Go
  5. Build web application with Golang

After reading those above, my brain and hands start to be itchy to try the language. And because I also wanted to learn about chatbot, and after reading Facebook Messenger Quick-Start, I decided to rewrite the messenger-bot in Go.

And then, this is what I have come up with so far: this go-messenger-bot Github repo.

Let me just paste its README.md here:


Facebook Messenger Quick-Start Sample in Golang https://glitch.com/edit/#!/project/messenger-bot

building and running

go build messenger-bot.go VERIFY_TOKEN=??? PAGE_ACCESS_TOKEN=??? ./messenger-bot

using docker

docker run --publish 8080:8080 --env VERIFY_TOKEN=??? --env PAGE_ACCESS_TOKEN=??? siriusdely/go-messenger-bot

OK, that’s it.

Point for improvements:

  • Use ngrok so that it can be tried live on FB Apps
  • Use Go Struct on JSON parsing
  • Use Wit.ai - probably for another blog post
  • Add some images/screenshots to this post to make it more interesting.
