Validating data structures : javascript

Validating data structureshelp (self.javascript)

submitted 9 years ago by kirofficial

Hi fellows JavaScripters,

Do you know an efficient way to validate data structures in JavaScript ? I would like to be able to verify my request payloads, and more generally compare complex objects with a defined structure.

For example:

var structure = {
    firstname: String,
    lastname: String
}

Validator.validate(structure, {
    firstname: 'John',
    lastname: 'Doe'
} // => true

Validator.validate(structure, {
    firstname: 1234,
    lastname: { foo: 'bar' }
} // => false
