addons-moz-compare

A JavaScript library to compare Mozilla add-on versions that follow the Manifest Version Format.

API

This library exposes a mozCompare() function that takes two (string) versions A and B and returns:

• -1 if A < B
• 0 if A == B
• 1 if A > B

This implementation matches the Firefox implementation except that there are only 3 different possible return values (Firefox returns strictly negative and strictly positive values instead of -1 and 1).

Usage

npm i addons-moz-compare

Node

const { mozCompare } = require('addons-moz-compare');

Browser

Use window.mozCompare after having included the source of this library.
