Packages

Declarative, schema-first authorization middleware for Absinthe GraphQL. Auth rules live next to the field they protect.

A powerful Elixir library for parsing and evaluating JSONPath expressions.

Fast arbitrary-precision decimal arithmetic for Elixir. A pure-Elixir alternative to the decimal library — ~10x faster on average across the common operations (add, sub, mult, div, compare, parse), with a drop-in compatibility shim, ~d sigil, and Ecto.Type.

HyParView membership protocol — a clean, BEAM-native implementation of the hybrid partial-view membership protocol from Leitão, Pereira, and Rodrigues (DSN 2007). Provides bounded partial views and reactive failure handling for large-scale peer-to-peer overlays.

Coyote-style controlled concurrency testing for the BEAM. PCT/POS scheduling, schedule shrinking, trace replay, Elixir + Erlang AST rewriters, and ETS / atomics / persistent_term sync points -- so message-passing AND shared-state races surface deterministically.

libcluster strategy that uses HyParView for membership: nodes are connected via Erlang distribution only when present in the local active view, giving Elixir clusters partial-mesh BEAM distribution.
