It will probably faster and for sure will cope a lot more under load, due to the BEAM, that is well exemplified here by @sasajuric.
We already have several projects in Elixir fore ecommerce:
- Crimsom repo and article.
- Shopix repo and aritcle.
- Freshcom repos. They have separated it in several repos.
- Many more here.
I don’t really know if any of them is being/continued to be used in production. I think Freshcom was being used in prod at some point or was about to launch. The author is here in the forum @rbao.
If you search the forum you have more questions like yours:
- Resources for building an e-commerce store in Phoenix?
- Presenting Aviacommerce, open source e-commerce in Elixir
I know that some people have ecommerce apps in Elixir in prod and that they around the forum, but don’t recall who they are.
