Ask HN: What would be your stack if you are building an MVP today?

After working with the PETAL (Phoenix, Elixir, TailwindCSS, Alpine.Js, Liveview) stack at $JOB for a while now, I have to say I've never been more productive. Early on I would still have to lean on Alpine heavily for various JS interactions but with all the features Liveview has been adding and improving on (Hello JS module!) I find myself needing it less and less. Liveview really has been a game changer for me. Tailwind has more or less fixed most of my frustrations with CSS and has worked itself nicely into the company design system resulting in nice re-usable components that can be easily customized for those one-offs. Elixir is a nice language to use and I find myself missing features of it when working with other languages. Phoenix is well structured for projects and the newer generators solve a lot of common issues/features in projects like user auth in a reasonable way.

I second this. I would say that I am pretty advanced with Python (and Django) and same with JavaScript (Vue and Nuxt) and have written applications that got used by multiple users. I saw a sharp rise in my productivity when I knew enough about the frameworks. But Elixir + PhoenixLiveView + Tailwind has been life changing.
I learned Elixir for the sake of the joy of learning a new programming language and I kept playing with it for few random days over 5-6 months. Finally, I took the leap of faith and for our startup I started the switch to Elixir + LiveView with minimal JavaScript hooks and I feel a weird bliss that we are two engineer FTEs and I can add features on a daily basis. Why that's the case, I still haven't ruminated myself, but my guess is 1. I have gotten older, 2. Elixir is beautiful and productive by design-- pattern matching, everything is a process (so the dimensionality of time is not an issue at all) and the code is kind of a right balance of simplicity and complexity, and in my opinionated view, there is "one" right way of doing things. 3. Standard tooling (mix, ExUnit). They have enabled us to write really maintainable code and for our next hires, we are willing to pay for them to learn Elixir than switching to other languages. Of course this is only for true for our web app which is actually a weird beast that interfaces farms, sensors, algorithms, and humans.

I also would choose Elixir/Phoenix. Having spent my career in Python/Django, Elixir/Phoenix/Live View is on another level of productivity.
For anyone needing a reason to jump into Elixir, take 40 minutes and watch this talk by Sasa Juric. He communicates things so well as to all the benefits of Elixir/Erlang/BEAM.
Then take the time to read Elixir in Action book (again, Sasa) and you'll be off to the races.
