Version Comparator

With the version comparator you can compare semver valid version strings. Additionally, the version comparator can compare version strings like 5.04, 5.06.

Install

npm install @mr42/version-comparator

Usage

Compare

Compare two version strings

import { compare } from '@mr42/version-comparator/dist/version.comparator';
// left < right
compare('4.04', '4.06') // -1
compare('4.4.1', '4.4.2') // -1
compare('4.04', '4.4.0') // -1, since left.length < right.length
// left > right
compare('4.06', '4.04') // 1
compare('4.4.2', '4.4.1') // 1
compare('4.4.0', '4.04') // 1, since left.length > right.length
// left == right
compare('4.06', '4.06') // 0
compare('4.4.1', '4.4.1') // 0
compare('4.04', '4.4') // 0

Less than equal

Checks if version1 <= version2

import { lte } from '@mr42/version-comparator/dist/version.comparator';
// check returns true
lte('4.04', '4.06') // true
lte('4.4.1', '4.4.2') // true
lte('4.04', '4.4.0') // true, since left.length < right.length
lte('4.06', '4.06') // true
lte('4.4.1', '4.4.1') // true
lte('4.04', '4.4') // true
// check returns false
lte('4.06', '4.04') // false
lte('4.4.2', '4.4.1') // false
lte('4.4.0', '4.04') // false, since left.length > right.length

Greater than equal

Checks if version1 >= version2

import { gte } from '@mr42/version-comparator/dist/version.comparator';
// check returns true
gte('4.06', '4.04') // true
gte('4.4.2', '4.4.1') // true
gte('4.4.0', '4.04') // true, since left.length > right.length
gte('4.06', '4.06') // true
gte('4.4.1', '4.4.1') // true
gte('4.04', '4.4') // true
// check returns false
gte('4.04', '4.06') // false
gte('4.4.1', '4.4.2') // false
gte('4.04', '4.4.0') // false, since left.length < right.length

Equal

Checks if version1 == version2

import { eq } from '@mr42/version-comparator/dist/version.comparator';
// check returns true
eq('4.06', '4.06') // true
eq('4.4.1', '4.4.1') // true
eq('4.04', '4.4') // true
// check returns false
eq('4.06', '4.04') // false
eq('4.4.2', '4.4.1') // false
eq('4.4.0', '4.04') // false, since left.length > right.length
eq('4.04', '4.06') // false
eq('4.4.1', '4.4.2') // false
eq('4.04', '4.4.0') // false, since left.length < right.length
