cached-validations
Create validation functions that cache results
Install
$ npm install --save cached-validations
Usage
Create a validation schema and then you can create a validation function that takes in values and outputs any errors based on the passed validation functions.
If an error has already been returned for a specific value then it will be cached and returned on the next invocation, making this a relatively performant option for doing things like form validations on keyup
.
; const formValidations = { if !email return 'Email is required'; if return 'Must be a valid email'; } { if !age return 'Age is required'; if age > 120 || age < 13 return 'Must provide a valid age.' } const formValidator = ; const dummyInput = email: 'notanemail' age: 44const errors = // {email: 'Must be a valid email'}
API
createValidator(validations: object) => function => object
Takes an object mapping validation functions to keys, returns a function that will validate objects with those same keys and return any errors based on the initially provided validations.
