version-compatibility v0.0.1

VersionCompatibility.js

Takes a matrix of primary semantic version numbers that are correlated with secondary semantic version ranges then allows you to quickly determine compatibility between the two sets of version numbers.

Example

    var VersionCompatibility = require('version-compatibility');

    // The key is the module version number
    // The value is the range of system versions that are compatible with the module version number
    var compatibilityMatrix = {
        '1.0.0': '2.4.x',
        '1.1.0': '2.4.x',
        '1.1.3': '2.4.7 - 2.4.x',
        '1.2.0': '2.5.x'
    };

    var versions = VersionCompatibility(compatibilityMatrix);

    versions.compatibilityMatrix;
    // { '1.0.0': '>=2.4.0-0', '1.1.0': '>=2.4.0-0', '1.1.3': '>=2.4.7 <2.5.0-0', '1.2.0': '>=2.5.0-0'}

    versions.all();
    // ['1.0.0','1.1.0','1.1.3','1.2.0']

    versions.compatibleWith('2.4.3'); // ['1.0.0','1.1.0']
    versions.compatibleWith('2.4.8'); // ['1.1.3']
    versions.compatibleWith('2.5.3'); // ['1.2.0']
    versions.compatibleWith('3.0.0'); // []

    versions.recommendedFor('2.4.3'); // '1.1.0'
    versions.recommendedFor('2.4.8'); // '1.1.3'
    versions.recommendedFor('2.5.3'); // '1.2.0'
    versions.recommendedFor('3.0.0'); // Null
