@flourish/semver v1.0.2

A short and simple module for parsing and comparing semantic version numbers, following the Semantic Versioning 2.0.0 specification.

Does not support build metadata.

const semver = require("@flourish/semver");

semver.parse("1.0.0");
// Returns [1, 0, 0]

semver.parse("1.0.0-alpha.1.2.3");
// Returns [1, 0, 0, "alpha", 1, 2, 3]

semver.join([1, 2, 3]); // "1.2.3"

semver.join([1, 2, 3, "alpha", 2]); // "1.2.3-alpha.2"

semver.cmp(semver.parse("1.2.0"), semver.parse("1.2.1")); // -1

semver.cmp(semver.parse("1.2.0"), semver.parse("1.2.0")); // 0

semver.cmp(semver.parse("1.2.2"), semver.parse("1.2.2-alpha.1")); // +1

semver.cmp(semver.parse("1.2.2"), semver.parse("1.2.3-alpha.1")); // -1

// Sort a list of version numbers into order
version_numbers
    .map(semver.parse)
    .sort(semver.cmp)
    .map(semver.join);
