Built-In Validator: min

The min validator checks that a numeric value is at least the minimum value provided.

If the value being validated is null, false, an empty string, or another falsy value other than 0, then the result will be valid. This respects the rule of thumb described in the notes for the required validator.

Named Props

  • min: The minimum value compared against


The min validator supports three parameter signatures:

  1. min(value) where the value is used as the min named prop
  2. min(propsObject) where the props object contains a min named prop
  3. min(propsFunction) where the props function returns a props object with a min named prop


import validate, {min} from 'strickland';

// As a value parameter
const minOf3 = min(3);

// As a named prop
const minOf2 = min({
    min: 2,
    message: 'Must be at least 2'}

// As a function that resolves to have the named prop
const minValidator = min((context) => ({
    min: context.min,
    message: `Must be at least ${context.min}`
