SemVerUtils

import { SemVerUtils } from '@kairo-js/utils'

Semantic version utility class. All methods are static. Provides comparison, formatting, and range-checking operations for SemVer objects.

Methods

• compare
• equals
• format
• isPrerelease
• rcompare
• satisfies

compare

static compare(a: SemVer, b: SemVer): number

Compares two semantic versions.

Parameters

• a: SemVer

  The first version.

• b: SemVer

  The second version.

Returns: number — A negative number if a < b, a positive number if a > b, or 0 if they are equal.

---

equals

static equals(a: SemVer, b: SemVer): boolean

Checks whether two semantic versions are equal.

Parameters

• a: SemVer

  The first version.

• b: SemVer

  The second version.

Returns: boolean — true if a and b represent the same version, otherwise false.

---

format

static format(version: SemVer): string

Converts a SemVer object to its string representation (e.g. "1.2.3" or "1.2.3-beta.1").

Parameters

• version: SemVer

  The version to format.

Returns: string — The formatted version string.

---

isPrerelease

static isPrerelease(version: SemVer): boolean

Checks whether a version is a pre-release version.

Parameters

• version: SemVer

  The version to check.

Returns: boolean — true if the version has a non-empty prerelease field, otherwise false.

---

rcompare

static rcompare(a: SemVer, b: SemVer): number

Compares two semantic versions in reverse order. Equivalent to compare(b, a). Useful for sorting a list of versions in descending order.

Parameters

• a: SemVer

  The first version.

• b: SemVer

  The second version.

Returns: number — A positive number if a < b, a negative number if a > b, or 0 if they are equal.

---

satisfies

static satisfies(version: SemVer, range: string): boolean

Checks whether a version satisfies a semver range string.

Parameters

• version: SemVer

  The version to test.

• range: string

  A semver range string (e.g. "^1.0.0", ">=2.1.0 <3.0.0").

Returns: boolean — true if version satisfies the given range, otherwise false.
