Compositional async utilities

Node-style async composition, translated for Java systems.

Queues, series, parallel work, retries, and fan-out are universal control-flow problems. Async Java translates the practical vocabulary of Node’s async ecosystem into patterns that fit Java runtimes.

Asynchrony is easier to reason about when the control flow has a name.

01 / PRINCIPLES

What the system protects.

Named control flow

Express series, parallel, queue, and retry behavior directly.

Multiple runtimes

Explore integrations for Vert.x, Akka, futures, and reactive styles.

Familiar semantics

Carry a proven async vocabulary into Java without hiding execution state.

02 / METHOD

A visible sequence.

01
Compose
Describe operations and the control-flow relationship between them.
02
Execute
Apply the chosen concurrency and error semantics.
03
Resolve
Return a result whose path through the pipeline remains understandable.

03 / ACCESS

One product. Clear account boundaries.
