reduxform-validator

Exposes methods validate and validateMany for validating your redux-form payloads. One would use it to get rid of the boilerplate when writing form field validations.

We also made a video tutorials if you are interested on how this library was inspired:

Installation via NPM / Yarn

npm install reduxform-validator --save

yarn add reduxform-validator

Usage

validate(predicate, value, error)

import * as v from 'reduxform-validator';

// Custom validator function
// You could also use any function from lodash/underscore etc.
const hasValue = val => val && val.length > 0;

const validate = values => ({
  name: v.validate(hasValue, values.name, 'enter your name'),
  surname: v.validate(hasValue, values.surname, 'enter your surname'),
});

validateMany(validators, value)

import * as v from 'reduxform-validator';

const validate = values => ({
  age: v.validateMany([
    {
      predicate: v => !!v,
      error: 'Please set your age',
    },
    {
      predicate: v => !isNaN(Number(values.age)),
      error: 'Age must be a number!',
    },
    {
      predicate: v => v >= 18,
      error: 'You must be at least 18 years old',
    },
  ], values.age),
});

Development (src, lib and the build process)

NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.

To build run npm run build To test run npm run test
