npm package memorial

ℹ︎ How to read this score
Signals, not verdicts. A ghost score (0–100) estimates the probability that a repository will go 12 months without a non-bot commit, become archived, or be deprecated. A high score is a prompt to check your dependency health — never an accusation against its maintainers.

yallist

“yallist did not die — it faded, release by release, until the pulse went flat.”

Día de los Muertos · Altar of Remembrance

Ofrenda

Every candle represents a person who gave time to yallist. In the Día de los Muertos tradition, an ofrenda welcomes back the memory of those who came before — honoring the hands that built the software we rely on.

Hold a seance

The spirit of yallist answers strictly from its own records — README, releases, and issues. It never impersonates a maintainer and says “I don't remember that” when evidence is missing.

The candles are lit. Pick a question above or ask what yallist did, how to migrate away, or how it ended.
