js-semver

A parser and evaluator for semantic versioning in JavaScript, such as Node.js and Deno.
It's a crate for the JavaScript ecosystem, designed to maintain minimal dependencies.

Example

use js_semver::{BuildMetadata, PreRelease, Range, Version};

fn main() {
    let range = Range::parse(">=1.2.3 <1.8.0").unwrap();

    // Pre-release versions are not included in the range unless explicitly specified.
    let version = Version {
        major: 1,
        minor: 2,
        patch: 3,
        pre_release: PreRelease::parse("alpha.1").unwrap(),
        build: BuildMetadata::default(),
    };
    assert!(!range.satisfies(&version));

    let version = Version::parse("1.3.0").unwrap();
    assert!(range.satisfies(&version));
}
