Semver extension for the [Joi][] validation library

[joi]: https://github.com/sideway/joi

Usage

``js
const { semver, semverRange } = require('joi-extension-semver')
const Joi = require('joi')
.extend(semver)
.extend(semverRange)

Joi.attempt('1.2.3', Joi.semver().valid()) // '1.2.3'
Joi.attempt('>=1.2.3', Joi.semverRange().valid()) // '>=1.2.3'

Joi.attempt('1.2.3', Joi.semver().gte('1.2.3')) // '1.2.3'
Joi.attempt('1.2.3', Joi.semver().lt('1.2.3')) // throws ValidationError
Joi.attempt('1.2.3', Joi.semver().satisfies('^1.0.0')) // '1.2.3'
`

Validation chains

See semver documentation. All boolean
returning comparisons are supported.

- Joi
- semver
- semver.valid()
- semver.gt(exp)
- semver.gte(exp)
- semver.lt(exp)
- semver.lte(exp)
- semver.eq(exp)
- semver.neq(exp)
- semver.cmp(cmp, exp)
- semver.satisfies(rng)
- semver.gtr(rng)
- semver.ltr(rng)
- semver.outside(hilo, rng)
- semverRange
- semverRange.valid()

$3

Starts the chain.

#### semver.valid()
Asserts valid(value).
#### semver.gt(exp)
Asserts gt(value, exp).
#### semver.gte(exp)
Asserts gte(value, exp).
#### semver.lt(exp)
Asserts lt(value, exp).
#### semver.lte(exp)
Asserts lte(value, exp).
#### semver.eq(exp)
Asserts eq(value, exp).
#### semver.neq(exp)
Asserts neq(value, exp).
#### semver.cmp(comp, exp)
Asserts cmp(value, comp, exp).
#### semver.satisfies(rng)
Asserts satisfies(value, rng).
#### semver.gtr(rng)
Asserts gtr(value, rng).
#### semver.ltr(rng)
Asserts ltr(value, rng).
#### semver.outside(hilo, rng)
Asserts outside(value, hilo, rng).

$3

Starts the chain.

#### semverRange.valid()
Asserts validRange(value)`.
