semver-compare-multi

Compare two semver version strings, returning -1, 0, or 1

They don't need to be strict x.y.z formated strings, the size is automaticaly checked. As the size is dynamic, comparing cmp("1.0.0", "1.0.0.1")returns -1, that is, the longer version is considered greater.

The return value of cmp can be fed straight into [].sort.

You can pass newComparer, which returns an cmp(a,b), an array of characters to match as split points, mind to escape regex special symbols with \\, as of: newComparer(["\\.", "-"])

example

import { cmp } from "semver-compare-multi";
var versions = [
    '1.2.3',
    '4.11.6',
    '4.2.0',
    '1.5.19',
    '1.5.5',
    '4.1.3',
    '2.3.1',
    '10.5.5',
    '11.3.0'
];
console.log(versions.sort(cmp).join('\n'));

Or

import { newComparer } from "semver-compare-multi";
var versions = [
    '1.2-3',
    '4.11_6',
    '4.2_0',
    '1.5-19',
    '1.5-5',
    '4.1-3',
    '2.3_1',
    '10.5_5',
    '11.3_0'
];
console.log(versions.sort(newComparer(["\\.", "-", "_"])).join('\n'));

prints:

1.2-3
1.5-5
1.5-19
2.3_1
4.1-3
4.2_0
4.11_6
10.5_5
11.3_0

whereas the default lexicographic sort (versions.sort()) would be:

1.2-3
1.5-19
1.5-5
10.5_5
11.3_0
2.3_1
4.1-3
4.11_6
4.2_0

methods

import { cmp, newComparer } from "semver-compare-multi";

cmp(a, b)

If the semver string a is greater than b, return 1. If the semver string b is greater than a, return -1. If a equals b, return 0;

It is the same as newComparer(), which returns an cmp(a, b) with "." and "-" default separators.

install

With npm do:
