## What it is
C++React is a reactive programming library for C++ that enables declarative definition of data dependencies between state variables and event flows. It builds a dependency graph to automatically propagate changes with correctness, consistency, and efficiency guarantees, including parallel updates.

## Use cases
- automatically recompute derived values when inputs change in C++
- replace manual callbacks with declarative signal bindings
- build event stream pipelines with filter, transform, and merge
- propagate state changes across a dependency graph
- parallelize reactive updates safely across threads
- model UI or simulation state as reactive signals

## When to choose
- you want reactive/functional-reactive programming idioms in C++14
- you need automatic, glitch-free change propagation with dependency tracking
- you want automatic parallelization of independent updates

## When to avoid
- you need a mature, well-documented release - the master branch is being rewritten and is broken/outdated
- you need long-term support or active maintenance
- your project targets C++11 only

## Facets
- artifact type: library
- maturity: experimental
- function: state-management, concurrency, developer-tools
- domain: developer-tools, programming-languages
- platform: cpp, cross-platform
- tags: reactive-programming, signals, event-streams, dataflow, declarative, c-plus-plus, algorithms
