Use Bun's semantic versioning API
Bun implements a semantic versioning API which can be used to compare versions and determine if a version is compatible with another range of versions. The versions and ranges are designed to be compatible with node-semver, which is used by npm clients.
It's about 20x faster than node-semver.
Currently, this API provides two functions:
Bun.semver.satisfies(version: string, range: string): boolean
Returns true if version satisfies range, otherwise false.
Example:
import { semver } from "bun";
semver.satisfies("1.0.0", "^1.0.0"); // true
semver.satisfies("1.0.0", "^1.0.1"); // false
semver.satisfies("1.0.0", "~1.0.0"); // true
semver.satisfies("1.0.0", "~1.0.1"); // false
semver.satisfies("1.0.0", "1.0.0"); // true
semver.satisfies("1.0.0", "1.0.1"); // false
semver.satisfies("1.0.1", "1.0.0"); // false
semver.satisfies("1.0.0", "1.0.x"); // true
semver.satisfies("1.0.0", "1.x.x"); // true
semver.satisfies("1.0.0", "x.x.x"); // true
semver.satisfies("1.0.0", "1.0.0 - 2.0.0"); // true
semver.satisfies("1.0.0", "1.0.0 - 1.0.1"); // true
If range is invalid, it returns false. If version is invalid, it returns false.
Bun.semver.order(versionA: string, versionB: string): 0 | 1 | -1
Returns 0 if versionA and versionB are equal, 1 if versionA is greater than versionB, and -1 if versionA is less than versionB.
Example:
import { semver } from "bun";
semver.order("1.0.0", "1.0.0"); // 0
semver.order("1.0.0", "1.0.1"); // -1
semver.order("1.0.1", "1.0.0"); // 1
const unsorted = ["1.0.0", "1.0.1", "1.0.0-alpha", "1.0.0-beta", "1.0.0-rc"];
unsorted.sort(semver.order); // ["1.0.0-alpha", "1.0.0-beta", "1.0.0-rc", "1.0.0", "1.0.1"]
console.log(unsorted);
