Derived only from GitHub GraphQL starredAt events after daily star totals are reconciled.

180 observed daily rows. Missing days are not fabricated.

Hotness formula

40% Hot today + 40% Hot this week + 20% Breakout.

  • 40% Hot today: 1
  • 40% Hot this week: 12
  • 20% Breakout: 25
  • Stars gained: 1d: 0
  • Stars gained: 7d: 3
  • Stars gained: 14d: 2315
  • Stars gained: 30d: 2315
  • Stars gained: 90d: 2315

Per-day formula: 0.40 Γ— Hot today + 0.40 Γ— Hot week + 0.20 Γ— Breakout.

  • Same-day multiplier = stars 1d Γ· max(1, stars 7d Γ· 7)
  • Weekly multiplier = stars 7d Γ· max(1, stars 30d Γ· 30 Γ— 7)
  • Fortnight multiplier = stars 14d Γ· max(1, stars 90d Γ· 90 Γ— 14)
  • Hot today = clamp(70 Γ— log-scale(stars 1d, 1000) + 30 Γ— breakout-scale(same-day, 4))
  • Hot week = clamp(75 Γ— log-scale(stars 7d, 5000) + 25 Γ— breakout-scale(weekly, 3))
  • Breakout = clamp(35 Γ— breakout-scale(same-day, 4) + 40 Γ— breakout-scale(weekly, 3) + 25 Γ— breakout-scale(fortnight, 2.5))

Full metrics details

Derived from the displayed continuity, closure, shipping, liveness, and support-burden components.

180 observed daily rows. Missing days are not fabricated.

Reliability formula

30% Continuity + 30% Closure + 20% Shipping + 10% Liveness + 10% Support burden.

  • 30% Continuity: 3
  • 30% Closure: 0
  • 20% Shipping: 0
  • 10% Liveness: 21
  • 10% Support burden: 16

Per-day formula: 0.30 Γ— Continuity + 0.30 Γ— Closure + 0.20 Γ— Shipping + 0.10 Γ— Liveness + 0.10 Γ— Support burden.

  • Continuity = 35% active ratio 90d + 20% active ratio 30d + 15% PR efficiency 90d + 10% PR efficiency 30d + 10% liveness + 10% observed-history coverage
  • Closure = 55% PR merge efficiency 90d + 45% issue close efficiency 90d
  • Shipping = 100 Γ— (20% Γ— release ratio 30d + 30% Γ— release ratio 90d + 50% Γ— release ratio 180d); ratios are releases Γ· 2, 6, and 12, capped at 1
  • Support burden = 100 βˆ’ 2 Γ— open issues per 1,000 stars
  • Liveness = 100 Γ— exp(βˆ’pushed days ago Γ· 120)

Stars, issues, pull requests, and releases are daily observations. Pushed-days and license are repository snapshot-derived inputs and are not independent historical GitHub events.

Reliability breakdown

What drives the reliability score

Component scores measured daily from GitHub activity (2026-07-18).

Continuity30% of headline3

Activity on 0 of 90 tracked days in the last 90 and 0 of 30 in the last 30.

Activity pulse
Closure30% of headline0

Merged 0 of 0 PRs opened and closed 0 of 0 issues opened over the last 90 tracked days β€” PR flow carries 55% of this component, issue flow 45%.

PRs merged (90d)PRs opened (90d)Issues closed (90d)Issues opened (90d)
Shipping20% of headline0

0 releases in the last 180 days, 0 in the last 90 and 0 in the last 30 β€” a steady cadence scores highest.

Releases
Liveness10% of headline21

Last push 329 days ago β€” freshness decays as pushes age (roughly halves every 83 days without a push).

About User Event

testing-library/user-event is a companion library for Testing Library that simulates realistic user interactions in the browser, including typing, clicking, tabbing, and clipboard actions. It models event sequences closer to real usage than low-level event dispatch helpers. The package is commonly used in frontend unit and integration tests for React, Vue, Angular, and other DOM-based frameworks.
