Usage

⚠ This library is ONLY compatible with node version 14 and above

First, you must import the library using the following code:

const versionTools = require('major-version-check');
// or `import * as versionTools from 'major-version-check';` for ESM users

Then all you have to do is call the function with some values:

const versionTools = require('major-version-check');
// or `import * as versionTools from 'major-version-check';` for ESM users

// Will return true
console.log(versionTools.majorVer('1.0.0', '2.0.0'));

// Will return false
console.log(versionTools.majorVer('1.0.0', '1.0.1'));

// Will return info about the version
console.log(JSON.stringify(versionTools.parseVersion('1.0.0-beta')));

// Will return true
console.log(`Output:\n${versionTools.compare(versionTools.parseVersion('1.0.1'), versionTools.parseVersion('1.0.0'), { type: 'greaterThan' })}`);

// Will return false
console.log(`Output:\n${versionTools.compare(versionTools.parseVersion('1.0.1'), versionTools.parseVersion('1.0.0'), { type: 'lessThan' })}`);

That's it! Now you have it running!
