- Dependency-free
- Tested on node & iojs
- Uses es6, so transpile for browser use
Note: Strings only!
This module simplifies validation that requires regular expressions or multiple steps. It will not include anything that is already simple to calculate and reason about, such as string length.
npm install --save s-valid
var valid = require('s-valid');
// simple validation
if (valid.email('email@test.com')) {
// ...
}
// primary use case: server-side form validation
if (!valid.email(req.body.email)) {
// return error...
}
Use it modularly if you prefer
var email = require('s-valid/email');
if (email('email@test.com')) {
// ...
}
valid.affirmative('yes'); // true
valid.affirmative('y'); // true
valid.affirmative('on'); // true
valid.affirmative('true'); // true
valid.negatory('no'); // true
valid.negatory('n'); // true
valid.negatory('off'); // true
valid.negatory('false'); // true
valid.alpha('Foo'); // true
valid.alpha('Foo bar'); // false
valid.alpha('Test123'); // false
valid.numeric('123'); // true
valid.numeric('-123'); // true
valid.numeric('123px'); // false
valid.numeric('$123000'); // false
valid.alphaNumeric('Test123'); // true
valid.alphaNumeric('Tést'); // false
valid.alphaNumeric('Test 123'); // false
valid.alphaNumeric('Test_123'); // false
valid.alphaNumeric('Test-123'); // false
Note: valid.creditCard()
is an alias for valid.card.generic()
valid.creditCard('4242424242424242'); // true (matches Visa regexp)
valid.creditCard('5610591081018250'); // true with no regexp match (Australian Bankcard)
valid.creditCard('1234123412341234'); // false

valid.card.amex('371449635398431'); // true
valid.card.amex('4242424242424242'); // false (is Visa)

Similar to numeric
, but less restrictive. Passes for $ (or any non-number first character), commas, and units (such as 12px or 38BTC)
valid.value('123'); // true
valid.value('-123'); // true
valid.value('#000000'); // true
valid.value('123px'); // true
valid.value('$123,000.00'); // true
valid.value('test'); // false
valid.value('Infinity'); // false
valid.url('http://test.com'); // true
valid.url('https://test.com'); // true
valid.url('https://test.com:3000'); // true -- works with port numbers
valid.url('http://4.35.153.221'); // true -- IP addresses are valid URLs
valid.url('http://300.35.153.221'); // false -- invalid IP addresses fail
valid.url('http:/test.com'); // false
valid.zipCode('89052'); // true
valid.zipCode('89052-6589'); // false
valid.zipCode('890526589'); // false
Additional 4-digit code is optional and must be separated by a hyphen
valid.zipCodeLong('89052'); // true
valid.zipCodeLong('89052-6589'); // true
valid.zipCodeLong('890526589'); // false
is.js provided some of the regular expressions used behind-the-scenes, however the following improvements have been made to them:
- URLs can include the port number and be IP addresses without failing
- Affirmative string values can include any capitalization
- "on" is also considered affirmative (useful for capturing checkbox values in POST requests)
- Negatory string values ("off", "no", "false") have been added
- More credit card types will pass validation
