## What it is
A small JavaScript library for retrying promise-returning or async functions with exponential backoff and customizable retry strategies. It supports aborting retries on non-retryable errors and provides failure context callbacks.

## Use cases
- retry failed http fetch requests
- add exponential backoff to async function calls
- retry flaky network operations in node
- stop retrying on 404 errors
- retry promise with custom retry strategy

## When to choose
- you need robust retry logic with exponential backoff for async operations
- you want fine-grained control over which errors are retried or aborted
- you need per-failure callbacks with retry state information

## When to avoid
- you need retry logic for non-promise synchronous code
- you need circuit breaker or rate limiting beyond simple retries
- your runtime lacks Promise support

## Facets
- artifact type: library
- maturity: active
- function: concurrency, error-handling
- domain: developer-tools, backend, web-development
- platform: browser
- tags: promise, retry, exponential-backoff, async, npm, nodejs, javascript
