What I use, 2023 edition

Hi, I’m Louis! I’m the the Gleam programming language guy.

It’s common for people to ask “will Gleam get metaprogramming?”. It’s a good question! A question that has a relatively complex answer, one that takes time to give. This post is an attempt to condense this conversation I’ve had many times into one document so that folks can get their answer more easily.

For the last few months I’ve been working with the Erlang Ecosystem Foundation and the Exercism team to create a Gleam syllabus for the Exercism platform, and as of this morning the final lesson has gone live!

I was talking to Josh over at Alembic and he mentioned that he was interested in taking advantage of Gleam’s compile-to-JavaScript capability and using it to make a front end for an Elixir Phoenix app. What a great idea!

The recently released Gleam v0.22 includes a new command to prepare a Gleam application for deployment. With this in mind I thought it would be a good time to show how deploy Gleam into production with my new favourite platform, Fly.io.
