Package Exports

composite-validation

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (composite-validation) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

For some data model...

const dataModel = {
    name: 'Leonardo',
    age: 45
};

...describe validation map that folows the structure of the original object.

import { ValidationMap, Conditions, required, equals } from 'composite-validation';

const map = ValidationMap({
    name: Conditions(v => required(v)),
    age: Conditions([
        v => required(v),
        v => equals(v, 21)

    },
