The JavaScript/TypeScript library that convert time string to seconds or milliseconds.

Install convert-time-string using npm:

npm install convert-time-string

Install convert-time-string using yarn:

yarn add convert-time-string

Install convert-time-string using pnpm:

pnpm add convert-time-string

The convertTimeString function takes a time string as input and returns the corresponding number of milliseconds. The time string can be in the format of a single time unit (e.g. "1h") or multiple time units separated by spaces or without spaces (e.g. "1h 30m" or "1h30m").

// in CommonJS
const { convertTimeString } = require('convert-time-string');

// or in ES module
import { convertTimeString } from 'convert-time-string';

Parameters:

import { TimeUnitOutPut } from 'convert-time-string';

convertTimeString(timeString: string, unitOutPut?: TimeUnitOutPut | string, leapYear?: boolean): number;

• timeString: The time string to convert.

  const timeString = '1h 30m';
  const timeValue = convertTimeString(timeString);
  console.log(timeValue); // Output: 5400000

• unitOutPut: The time unit to convert to. Can be "second" or "millisecond". Default is "millisecond". Hint: You can use the TimeUnitOutPut enum to avoid typo.

  const timeString = '1h 30m';
  const timeValue = convertTimeString(timeString, 'millisecond'); // default is "millisecond"
  console.log(timeValue); // Output: 5400000
  
  const timeValue = convertTimeString(timeString, 'second');
  console.log(timeValue); // Output: 5400

• leapYear: Whether to consider leap year when converting to "y" (years). Default is false.

  const timeString = '1y';
  const timeValue = convertTimeString(timeString, 'second', false); // default is false
  console.log(timeValue); // Output: 31536000000
  
  const timeValue = convertTimeString(timeString, 'second', true);
  console.log(timeValue); // Output: 31622400000
