From 34% to 96%: The Porting Initiative Delivers - Hologram v0.7.0
Hologram v0.7.0 is out! This is a milestone release for the Elixir-to-JavaScript porting initiative. 49 contributors ported 150 Erlang functions across 19 modules, pushing client-side Erlang runtime coverage from 34% to 96% and overall Elixir standard library readiness from 74% to 87%.
This means the vast majority of Elixir standard library functions needed for full-stack web and basic local-first apps now work in the browser - string processing, collections, sets, binary operations, Unicode normalization, math, time operations, file path handling, and more.
Beyond porting, the release includes enhancements, bug fixes, and infrastructure groundwork.
Thanks to our sponsors for making sustained development possible: Curiosum (Main Sponsor), Erlang Ecosystem Foundation (Milestones Sponsor), and our GitHub sponsors - Innovation Partner: @sheharyarn, Framework Visionaries: @absowoot, @uzairaslam196, Oban, @Lucassifoni, @robertu, and all other GitHub sponsors.
If you took part in the porting initiative, drop a comment - I’d love to give you a shout-out!
