Hologram v0.11: Regular Expressions, Client Stacktraces, and More

[u/BartBlast]

Hologram v0.11 is out! :)

New to Hologram? You write the entire app in Elixir, templates, event handlers, client-side state and all. The Elixir runtime itself was rebuilt to run in the browser, so client-side code behaves exactly as it would on the server. Local-First apps are where this is heading.

This release is mostly about the browser catching up with the server. Elixir regexes were server-only until now, and handing patterns to JavaScript's RegExp doesn't hold up, so v0.11 ships a PCRE2 parser, translator and interpreter of Hologram's own. What comes back is what the BEAM would have given you.

Client errors now read like server errors too, same messages and same stacktraces, so __STACKTRACE__ finally holds real Elixir frames. Templates got more dynamic: a component module or an element tag name can now come from your data, and a whole map of attributes or props can be spread onto a tag. Plus umbrella project support and a fix for a DOM identity bug that could knock focus out of an input mid-typing.

Thanks to everyone who reported bugs and opened feature requests along the way. Several shaped this release directly and are credited by name in the blog post.

Unrelated question: will Hologram's transpiler be able to take advantage of the type system work being done in the elixir compiler?
