Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 5702, "days_push": 855, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A native Node.js C++ addon providing fiber/coroutine support for V8, allowing jumping between multiple call stacks within a single thread. The author now recommends avoiding it in favor of async/await, Promises, and Generators.

## Use cases
- run synchronous code in an async node environment
- coroutine support for nodejs
- make sync library play nicely with async code
- fibers for v8
- legacy nodejs coroutine library

## When to choose
- maintaining legacy code that already depends on fibers
- running on old Node.js versions before v16

## When to avoid
- starting any new project
- using Node.js v16 or later (incompatible)
- modern async workflows - use async/await instead

## Facets
- artifact type: library
- maturity: maintenance
- function: concurrency
- domain: developer-tools, backend
- platform: windows
- tags: fibers, coroutines, v8, native-addon, obsolete, async, nodejs, linux, macos
