Validate javascript object
import ValidaJs from 'valida-js'
const rules = ValidaJs.rulesCreator(ValidaJs.validators, [
{
name: 'firstName',
type: 'required',
stateMap: 'firstName'
},
{
name: 'email',
type: 'required',
stateMap: 'email'
},
{
name: 'email',
type: 'isEmail',
stateMap: 'email'
},
{
name: 'email',
type: 'minLength',
stateMap: 'email',
compareWith: 10
}
])
const state = {
firstName: '',
email: ''
}
const validation = ValidaJs.validate(rules, state)
expect(validation.valid).toBe(false)
expect(validation.errors.firstName).toEqual(['required'])
expect(validation.errors.email).toEqual(['required', 'isEmail', 'minLength'])
The library has available this validators
- minLength
- maxLength
- required
- compareFields
- isEmail
- regex
But you can extend with your own validators, using the next signature
import ValidaJS from 'valida-js'
ValidaJS.validators['newRuleName'] = (stateMap, type, name, compareWithValue, defaultValue = '') => {
return (state) => {
const isValid = !!state[stateMap] // Any type of validation here
/**
* factoryValidationObj
* @param {boolean} isValid
* @param {string} type
* @param {string} name
* @return {Object}
* */
return ValidaJS.factoryValidationObj(isValid, type, name)
}
}
/*
after that in the createRules you will have that available as:
ValidaJs.rulesCreator(validators, [
{
name: 'firstName',
type: 'newRuleName',
stateMap: 'firstName'
}
])
*/
export default validators
