## What it is
NoFlo is a JavaScript implementation of Flow-Based Programming (FBP), where applications are defined as graphs of independent components communicating via message passing. It runs on both Node.js and the browser and can be used for full flow-based applications or to manage complex workflows and ETL processes.

## Use cases
- build data pipelines and ETL workflows in JavaScript
- coordinate asynchronous processes as visual graphs
- run flow-based applications on Node.js
- build event-driven browser applications with component graphs
- visually design and live-program applications
- wire up IoT devices and art installations with dataflows

## When to choose
- you want to separate control flow from logic using flow-based programming
- you need to orchestrate complex asynchronous data flows in JavaScript
- you prefer visual/graph-based application design
- you want reusable, reconnectable black-box components

## When to avoid
- you need a traditional web framework or UI toolkit
- your team prefers imperative or OOP paradigms
- you need minimal overhead for simple synchronous logic
- you require strong static typing across the graph
