valid-point v1.0.1

Welcome to Valid Point

A simple extensible validation module.

API

Valid Point is written with ES6 syntax, so you'll need a transpiler such as Babel or Traceur.

Validating Fields

To validate your fields, just pass in an object with your data and your validations.

const validate = require('valid-point');

validate({
    data: {
        name: null
    },
    validations: {
        name: {
            required: true
        }
    }
}); // Throws an error because name is null

Each field of data can have as many validations as you'd like.

Out of the box Rules

Currently, we have a few validation rules that are available without any effort:

• required

validate({
    data: {
        name: null
    },
    validations: {
        name: {
            required: true
        }
    }
}); // Throws an error because name is null

• alphanumeric

validate({
    data: {
        name: '123-a'
    },
    validations: {
        name: {
            alphanumeric: true
        }
    }
}); // Throws an error because the name has a dash in it

• string

validate({
    data: {
        name: 33
    },
    validations: {
        name: {
            string: true
        }
    }
}); // Throws an error because name is a number, not a string

• number

validate({
    data: {
        name: '33'
    },
    validations: {
        name: {
            required: true
        }
    }
}); // Throws an error because name is a string, not a number

You can easily add your own as well.

Creating Custom Rules

New rules can be added globally to the validator, by calling the addRule() method:

validate.addRule('phoneNumber', {
    message: 'Please enter a valid phone number',
    fn: (value) => {
        return value.match(/\d/g).length === 10;
    }
});

You can also pass in a rule to the validations object if you have a rule that you only want to apply to the current validation instead of being available globally:

validate({
    data: {
        number: '33'
    },
    validations: {
        number: {
            phoneNumber: {
                message: 'Please enter a valid phone number',
                fn: (value) => {
                    return value.match(/\d/g).length === 10;
                }
            }
        }
    }
});
