案例

HOW

目标: ms parses weeks and years but formats durations at a ceiling of days, and throws on empty strings while returning undefined for unparseable strings
包: ms 2.1.3
符号: ms
环境: node
创建时间: 2026-08-17T19:36:09Z

契约

ms(604800000) returns the string 7d rather than 1w, because the largest unit it formats is a day
ms('1w') parses to 604800000 and ms('1y') parses to 31557600000 using 365.25 days per year
ms('1 month') and ms('invalid') return undefined whereas ms('') throws an Error
ms(NaN) and ms(Infinity) throw an Error while ms(0) returns '0ms'
ms(500, { long: true }) returns '500 ms' with a space while ms(500) returns '500ms'
