Built-in Validators

Built in validators are implemented here. Here is a list of the validators and what they do:

number

Checks that the value is numeric - and that it's within the fields min & max range, if these are defined in the schema.

integer

Checks that the value is a valid Javascript Number - and that it's an integer.

double

Checks that the value is a valid number.

string

Checks that the value is a string - and that its length is within the fields min & max range, if these are defined in the schema.

array

Checks that the value is an array - and that the arrays length is within the fields min & max range, if these are defined in the schema.

Expects the value to be a valid Javascript array literal - something like this: ["John", "Doe", "Jane"] or [1, 2, 3].

date

Checks that the value is a valid Javascript Date - and that the date is between the fields min and max dates, if these are defined in the schema.

regexp

Checks that the value matches the regex defined in the fields schema.pattern. If schema.pattern isn't set, validation is skipped.

email

Checks that the value is a plausible looking email address, using a regular expression.

url

Checks that the value is a plausible looking http url, using a regular expression. Among other checks, the URL needs to start with http:// or https://.

creditCard

Checks that the value is a valid credit card number, using code from here.

alpha

Checks that the value is a letter, using this regex: /^[a-zA-Z]*$/

alphaNumeric

Checks that the value is a letter or a number, using this regex: /^[a-zA-Z0-9]*$/
