Provides a few wrappers around Joi's validate()
, attempt()
and assert()
functions with their arguments
re-ordered for easier currying / partial application
npm i joi-fp
When using functions like joi.validate()
, you will almost always have values for schema
and/or options
before you have the value
being validated. This little library re-orders the arguments of joi.validate()
, joi.attempt()
and joi.assert()
allowing you to pass the data you have initially, well, initially :) This library also has a few versions of these functions with fixed arities to make currying and partial application easier.
const _ = require('lodash')
const joi = require('joi-fp')(require('joi'))
// example with currying
const validateInput = _.curry(joi.validateFp3)({
name: joi.string().required()
})({allowUnknown: true});
validateInput({name: 'Max', color: 'blue'})
// { error: null, value: { name: 'Max', color: 'blue' } }
// example with partial application
const validateInputAgain = _.partial(joi.validateFp, {
name: joi.string().required()
}, {allowUnknown: true});
validateInputAgain({name: 'Max', color: 'blue'}, (err, value) => {
console.log(err, value) // null { name: 'Max', color: 'blue' }
})
// fixed arity for easy currying / partial application
