Package Exports
- react-joi
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-joi) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
About
State-based validation hook. Unlike other component/form based validations, react-joi allows you to use native HTML elements & requires no <form /> element to do your submit validation.
The core validator uses Joi as in it's name.
Installation
install package via npm install joi
yarn add react-joi
// or
npm -i react-joiUsage
import Joi from "joi"
import { useValidator } from "react-joi"
function App() {
const { state, setData, validate } = useValidator({
initialData: {
name: null,
email: null,
},
schema: Joi.object({
name: Joi.string().required(),
email: Joi.string()
.email({
tlds: { allow: false },
})
.required(),
}),
})
