fonk-min-number-validator

CircleCI NPM Version bundle-size

This is a fonk microlibrary that brings validation capabilities to:

  • Validate if a number field of a form is greater (or optionally equal) than a minimum value

How to install it:

npm install @lemoncode/fonk-min-number-validator --save

How to add it to an existing form validation schema:

We have the following form model:

const myFormValues = {
  product: 'shoes',
  price: 20,
}

We can add a minNumber validation to the myFormValues

import { minNumber } from '@lemoncode/fonk-min-number-validator';
 
const validationSchema = {
  field: {
    price: [minNumber.validator],
  },
};

We can specify the minimun value allowed and if it is inclusive:

import { minNumber } from '@lemoncode/fonk-min-number-validator';
 
const validationSchema = {
  field: {
    price: [
      {
        validator: minNumber.validator,
        customArgs: { minValue: 5, inclusive: false },
      },
    ],
  },
};

You can specify the custom arguments in two ways:

  • Locally just customize the arguments for this validationSchema:
import { minNumber } from '@lemoncode/fonk-min-number-validator';
 
const validationSchema = {
  field: {
    price: [
      {
        validator: minNumber.validator,
        customArgs: { minValue: 5, inclusive: false, strictTypes: true },
      },
    ],
  },
};
  • Globally, replace the default custom arguments in all validationSchemas (e.g. enable strict types):
import { minNumber } from '@lemoncode/fonk-min-number-validator';
 
minNumber.setCustomArgs({ minValue: 5, inclusive: false, strictTypes: true });

You can customize the error message displayed in two ways:

  • Globally, replace the default error message in all validationSchemas (e.g. porting to spanish):
import { minNumber } from '@lemoncode/fonk-min-number-validator';
 
minNumber.setErrorMessage('El campo debe de ser mayor que {{minValue}}');
  • Locally just override the error message for this validationSchema:
import { minNumber } from '@lemoncode/fonk-min-number-validator';
 
const validationSchema = {
  field: {
    price: [
      {
        validator: minNumber.validator,
        message: 'Error message only updated for the validation schema',
      },
    ],
  },
};
