## What it is
EventProxy is a lightweight JavaScript library implementing a task/event-based asynchronous pattern to coordinate multiple async operations. It decouples complex business logic via events, eliminating deep callback nesting and turning serial waits into parallel waits.

## Use cases
- avoid deep nested callbacks in node.js
- wait for multiple async requests in parallel
- coordinate several ajax calls before rendering
- event-based async flow control in javascript
- simplify error handling across async tasks
- replace callback hell in browser and node

## When to choose
- you maintain a legacy callback-style codebase without promises
- you need a tiny dependency-free async coordination tool for browser and node
- you prefer event-driven decoupling of multi-step async logic

## When to avoid
- you're starting a new project - use native Promises or async/await instead
- you need advanced async control flow like cancellation or streams
- you want an actively developed library with recent releases

## Facets
- artifact type: library
- maturity: maintenance
- function: concurrency, error-handling, developer-tools
- domain: developer-tools, web-development
- platform: browser, cross-platform
- tags: event-emitter, async-control-flow, callback-nesting, promise-alternative, frontend-backend, javascript, asynchronous-programming, nodejs
