range
The
range
validator combines the min
and max
validators to check that a value is within a range. Both the min
and max
values are inclusive.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.min
: The minimum value compared againstmax
: The maximum value compared against
The
range
validator supports three parameter signatures:- 1.
range(min, max)
where themin
andmax
named props are specified as values - 2.
range(propsObject)
where the props object containsmin
andmax
named props - 3.
range(propsFunction)
where the props function returns a props object withmin
andmax
named props
import validate, {range} from 'strickland';
// As value parameters
const between5and10 = range(5, 10);
// As named props
const between10and20 = range({
min: 10,
max: 20,
message: 'Must be between 10 and 20'
});
// As a function that resolves to have the named props
const rangeValidator = range((context) => ({
min: context.min,
max: context.max,
message: `Must be between ${context.min} and ${context.max}`
}));
