compare-versions
A simple version comparison tool.
The comparison principle is very simple, the version string is converted into a string of the same length, the default is 10, and then directly determine the size. But if the version of the type is inconsistent, such as 3.13.1
and 3.14
, may get unexpected results, So, please make sure the version type you entered is the same.
'3.13.1'
=> '0000000003.0000000013.0000000001'
Judgment rules and return results are as follows:
- if a > b, return 1
- if a === b, return 0
- if a < b, return -1
- if (versions type is inconsistent) return null
Install
npm install -S @workplus/compare-versions
