Leveldown SemVer Query Parser

This parser parses semantic versioning range queries like ^1.3.4 to leveldown compliant queries like { gte: '001003004', lt: '002000000' }. Note that for these queries to work, the version numbers must be in the format of 001003012 (1.3.12).

Pre-Release versions (such as 1.2.3-alpha.3) and the || operator are not supported.

Beware of dragons, this parser might not catch all cases yet.

Example

let SemverRangeParser = require('leveldown-semver-range-parser')

const parser = new SemverRangeParser()
// prints '{ gte: '001003004', lt: '002000000' }'
console.log(parser.parse('^1.3.4'))
// prints '{ gt: '001003004', lte: '004005002' }
console.log(parser.parse('>1.3.4 4.5.2'))
