conver v1.2.0

conver

Comparisons for concrete semantic versions (i.e. compare 1.2.3 instead of ^1.2.3).

Motivation

semver is a great implementation of semantic versioning; including all the edge cases. These edge cases are important in many scenarios, but often we are simply comparing two concrete versions (i.e. compare 1.2.3 instead of ^1.2.3).

In this more limited use-case case including all 1000+ lines of semver into your bundle for a web application is a bit of overkill. conver aims to do ONLY concrete version comparisons in a drastically smaller package size (currently 28 LOC excluding comments).

Usage

conver exposes the same comparison methods you would expect from the semver package. Specifically:

• gt(v1, v2): returns true if v1 is greater than v2.
• lt(v1, v2): returns true if v1 is less than v2.
• equal(v1, v2): returns true if v1 is equal to v2.
• compare(v1, v2) returns 0 if v1 == v2, or 1 if v1 is greater, or -1 if v2 is greater.
• parse(v1): returns an array of [major, minor, patch, build]
• stringify(src): returns a string representation of the specified src – an Array of [major, minor, patch, build].

conver.gt('3.4.5', '1.2.3'); // true
conver.gt('1.2.3', '3.4.5'); // false

conver.lt('1.2.3', '3.4.5'); // true
conver.lt('3.4.5', '1.2.3'); // false

conver.eq('1.2.3', '9.8.0'); // false
conver.eq('1.2.3', '1.2.3'); // true

conver.parse('1.2.3');       // [1, 2, 3, '']
conver.parse('1.2.3-alpha'); // [1, 2, 3, 'alpha']

conver.stringify([1, 2, 3, 'alpha']); // '1.2.3-alpha'
conver.stringify([1, 2, 3]);          // '1.2.3'
conver.stringify([1, 2]);             // '1.2'
conver.stringify([1]);                // '1'
