QuickBEAM

Judgement

What it is

Building block

What it does

Runs JavaScript inside Elixir and Erlang applications, with each runtime as a supervised process that has Web APIs, a DOM and a TypeScript toolchain.

Adopt it when

Your Elixir app needs to run JavaScript, such as server-side rendering of a Svelte or Vue bundle, without calling out to Node.js.

Watch out

It is eight months old and pre-1.0, with native code built in Zig that adds build complexity.

Ready for

Experimental
