vue-properties v1.0.0

Vue.js properties

npm install vue-properties

Allowing a string to be one of a set

import {oneOf} from 'vue-properties';

export default {
    props: {
        size: {
            type: String, 
            validator: oneOf('large', 'medium', 'small')
        }
    }
}

Matching a property by regular expression

import {regex} from 'vue-properties';

export default {
    props: {
        field: {
            type: String, 
            validator: regex(/[A-Z][a-z]+/)
        }
    }
}

Checking whether an integer is between two numbers

import {range, between} from 'vue-properties';

export default {
    props: {
        percentage: {
            type: Integer, 
            validator: range(0, 100)
        },
        teen: {
            type: Integer,
            validator: between(0, 20)
        }
    }
}

:bulb: range() is inclusive (so 0 and 100 also match). between() is exclusive, so 0 and 20 don't match.

Checking whether an integer is smaller or greater

import {smallerThan, biggerThan} from 'vue-properties';

export default {
    props: {
        canDrink: {
            type: Integer, 
            validator: biggerThan(18)
        },
        negative: {
            type: Integer,
            validator: smallerThan(0)
        }
    }
}

This is a set of handy validators for Vue.js.
