Usage is a two steps process.
First, a schema is constructed using the provided joi and constraints:. Note that joi schema objects are immutable which search every additional rule added e.
Converts literal schema definition to joi schema object or returns the same back if already a joi schema object where:. Note that this whitelist of allowed values is in addition to any other permitted values. To create an exclusive whitelist of values, see any. Adds the store room sex values into the allowed whitelist and marks them as the only valid values allowed where:.
Marks a key as required which will not allow undefined as value. All keys are optional by default.

Marks a key as optional which will allow undefined as values. Used to annotate the schema for readability as all keys are optional by default. Marks a key as forbidden joi will not allow any value except undefined.
Used to explicitly forbid keys.

Marks a key to be removed from a resulting object or array after validation. Used to sanitize output. Naked girls huge insertions mode sets the options. Note that if value is an object, any changes to the object after default is called will change the reference and any future assignment.
Additionally, when specifying a method you must either have a description property on your method or the second parameter is required. Converts the type into an alternatives type where the conditions are merged into the type definition where:. Alternatively, if you want to specify a specific type such as stringarrayetc, you can do so like this:. Generates a schema object that matches an array data type.
Note that undefined values inside arrays are not allowed by default but joi be by using sparse. Allow this array to be sparse. If a given type is. If a type is. Required items can be added multiple times to signify that multiple items must be found.
Errors will contain the number joi items that didn't match. Any unmatched item having a label will be mentioned explicitly. Be aware that a deep equality is performed on elements of the array having a type of objecta performance penalty is to be expected for this kind of operation. Generates a schema object that matches a boolean data type as well as the strings 'true', 'false', 'yes', 'no', 'on' or 'off'. Can also be called via bool.
Generates a schema object that matches a Buffer data type as well as the strings which will be converted to Buffers. Generates a schema object that matches a date type as well as a Joi date string or number of milliseconds. Generates a schema object that matches a number data type as well as strings that can be converted to numbers. Infinity and -Infinity are invalid by default, you can change that behavior by calling allow Infinity, -Infinity.
Generates a schema object that matches an object data type as well as Search strings that parsed into objects. Defaults to allowing any child key. Defines an all-or-nothing relationship between keys where if one of the peers is present, all of them are required as well where:.

Defines a relationship between keys where one of the peers is required and more than one is allowed where:. Defines an exclusive relationship between a set of keys where search of them is required but not at the same time where:. Note that unlike object. Overrides the handling of unknown keys for the scope of the current object only does not apply to search where:. Note that in this example search means the current object, a is not required but b is, as well as c and d.
Generates a schema object that matches a string data type.
Note that empty strings are not allowed by default and must be enabled with allow ''. Requires the number to be a credit card number Using Lunh Algorithm. Replace characters matching the given pattern with joi specified replacement string where:. Requires the string value to be a valid hostname as per RFC Requires the string value to be all lowercase. If the validation convert option is on enabled by defaultthe string will be forced to lowercase.
Requires the string value to be all uppercase. If the validation convert option is on enabled by defaultthe string will be forced to uppercase. Requires the string value to contain no whitespace before or after. If the validation convert option is on enabled by defaultthe string joi be trimmed. Generates a type that will match one of the provided alternative schemas via the try method. If no schemas are added, the type will not match any value except for undefined.
Adds a conditional alternative schema type based on another key not the same as any. Note that when only adds additional alternatives to try and does not impact the overall type. Setting a required rule on a single alternative will not apply to the overall key. For example, this definition of a:. Does not turn a into a required key when b is true. Instead, it tells the validator to try and match the value to anything that's your pleasure hot pantyhose porn undefined.
However, since Joi. This rule is the same as Joi. Generates a reference to the value of the named key. References are resolved at validation time and in order of dependency so that if one key validation depends on another, the dependent naked girls pussy panties is validated second after the reference is validated.
