validate-by-shorthand
This library offers a wide range of validation tests, easily accessible via shorthands.
Usage
var validate = require('validate-by-shorthand');
// validate using shorthands
validate('string!empty', 'foo'); // true
validate('string!empty', ''); // false
validate('number>0', 5); // true
validate('number>0', 0); // false
validate('string[]', ['foo', '', 'bar']); // true
validate('string[]', ['foo', '', 5]); // false
// validate using regular expressions
validate(/^[A-Z]+$/, 'ABC'); // true
validate(/^[A-Z]+$/, 'abc'); // false
// validate using functions
var test = function(v) {
return [1,2,3].indexOf(v) !== -1;
};
validate(test, 2); // true
validate(test, 5); // false
// validate using an array of shorthands, regexps and/or functions
// returning true if any test succeeds
var arr = ['number<0', test, /^[A-Z]$/];
validate(arr, -2); // true
validate(arr, 0); // false
validate(arr, 2); // true
validate(arr, 5); // false
validate(arr, 'A'); // true
validate(arr, 'a'); // true
