It’s honestly been one of the smartest choices we’ve made. We’ve been running it for four or five years now. It powers high throughput systems and those systems are classified as critical (if they go down, most of the product goes down.) Not a single regret. New hires new to Elixir have spun up on it very quickly, in my opinion what a team needs is one or two people experienced in Elixir to give some initial guidance but you don’t need a staff of experienced Elixir engineers to do great work. I have not found it a hard language to teach. Personally I’ve found the library ecosystem very strong, and writing our own libraries has not been hard. It’s important to note that interop with Erlang is quite good, so you have access to decades of library development from the Erlang ecosystem in addition to libraries written in Elixir. The basic elements you’re given out of the box for handling fault tolerance and concurrency are graceful and intuitive. The performance has also deeply impressed us. On a personal level, it’s also the most enjoyable language I’ve worked in and I’ve had very good experiences with the community. I find the tooling very good, including the VSCode extension (I have contributed a few features) but the default dialyzer setting definitely does hog the CPU on first build. I disabled it since we don’t get much out of it. I’ve built and run software in production in a lot of different languages over the last 15 years. Nothing has compared to Elixir, not even close. YMMV, I’m not here to refute the experiences of others, I’m just here to say for us it’s been an incredible experience. Absolute joy to use.
