HOW

ゴール: Evaluate custom usage statistics with browserslist popularity queries and coverage calculations
パッケージ: browserslist 4.28.8
シンボル: browserslist
browserslist.coverage
環境: node
作成日: 2026-08-17T12:46:26Z

browserslist('> 10%', { stats }) evaluates against global caniuse-lite usage data and ignores opts.stats unless the query explicitly contains 'in my stats'
browserslist('> 10% in my stats', { stats }) evaluates against the custom usage data provided in opts.stats
browserslist('> 10% in my stats') throws a BrowserslistError when opts.stats is omitted
browserslist.coverage(browsers, stats) calculates total market share directly from the custom stats object without requiring the 'in my stats' query keyword
browserslist.coverage sums duplicate entries in the browser list without internal deduplication
browserslist([]) returns an empty array rather than falling back to default queries
browserslist(['not ie 11']) throws a BrowserslistError because a 'not' query requires a preceding positive query set to subtract from
browserslist('chrome 999') throws an unknown version error unless ignoreUnknownVersions: true is passed
