It's a super simple article.
I wanted to know if this works with Ubuntu. I have been getting an error message that looks like this

zeitwerk requires Ruby version >= 2.4.4. The current ruby version is

I have been trying to update Ruby but it keeps saying this

ruby2.5 is already the newest version (2.5.5-1ubuntu1)


Hmm. That sounds like an issue with rbenv, asdf, or RVM (whichever you use).


I have this error when tryin to use it on windows

The number one thing to look at is Tung's LinkedIn Profile as he is quite creative with media attachments and I've learned a few things from him.

I was bit hoping for a more complete example of Jets. Was wondering if this was backed by DynamoDB or Aurora Serverless if it was using Terraform or possibly CloudFormation to manage these resources.

Maybe if I can connect with Tung I could do a tech talk in Toronto at the Serverless meetup on Ruby on Jets.

The biggest question I would have asked Tung is why didn't he call it Ruby on Rockets.


You can hook it up to Dynamo for sure. Planning to do a more complete article later.


The commands looks similar to RoR's commands. Does Jets aims to follow the same 'convention over configuration' path?


To a degree, Jets is very young and the commands are largely designed to smell like Rails.


I don't get it. Is it like 1 big function? Or jets doing a magic on separation?


The second one. The short version: every public method becomes a function, your routes become gateways, jobs are scheduled with cloudwatch, etc.

If you don't want to wait for me to write more articles, Tung has a ton of content at!


Very simple and straightforward...😱😱😱 Amazing. Can't wait for the next article...


Thanks! This is just to get a couple of people interested in the framework. I'll write a much more useful article in the future 😉
