# IntlTelInput React Component
A React component wrapper for the [intl-tel-input](https://github.com/jackocnr/intl-tel-input) JavaScript plugin. View the [source code](https://github.com/jackocnr/intl-tel-input/blob/master/react/src/intl-tel-input/react.tsx).

## Demo and Examples
Check out [Storybook](https://intl-tel-input.com/storybook/?path=/docs/intltelinput--vanilla) where you can play with the various props. Alternatively, try it for yourself by downloading the project and opening /react/demo/validation.html (etc) in a browser.
## Getting Started
```js
import IntlTelInput from "intl-tel-input/reactWithUtils";
import "intl-tel-input/styles";
<IntlTelInput
onChangeNumber={setNumber}
onChangeValidity={setIsValid}
initOptions={{
initialCountry: "us",
}}
/>
```
See the [Validation demo](https://github.com/jackocnr/intl-tel-input/blob/master/react/demo/validation/ValidationApp.tsx) for a more fleshed-out example of how to handle validation.
A note on the utils script (~260KB): if you're lazy loading the IntlTelInput chunk (and so less worried about filesize) then you can just import IntlTelInput from `"intl-tel-input/reactWithUtils"`, to include the utils script. Alternatively, if you use the main `"intl-tel-input/react"` import, then you should couple this with the `loadUtils` initialisation option - you will need to host the [utils.js](https://github.com/jackocnr/intl-tel-input/blob/master/build/js/utils.js) file, and then set the `loadUtils` option to that URL, or alternatively just point it to a CDN hosted version e.g. `"https://cdn.jsdelivr.net/npm/intl-tel-input@25.3.1/build/js/utils.js"`.
## Props
Here's a list of all of the current props you can pass to the IntlTelInput React component.
**disabled**
Type: `Boolean`, Default: `false`
Sets the disabled attribute of both the telephone input and selected country button. _Note: we recommend using this instead of `inputProps.disabled`._
**initialValue**
Type: `String`
The initial value to put in the input. This will get auto-formatted on init (according to `formatOnDisplay` initialisation option). IntlTelInput is an uncontrolled input, and so will ignore any changes to this value.
**initOptions**
Type: `Object`
An object containing the [initialisation options](https://github.com/jackocnr/intl-tel-input?tab=readme-ov-file#initialisation-options) to pass to the plugin. You can use these exactly the same way as with the main JavaScript plugin.
**inputProps**
Type: `Object`
The props to pass to the input element e.g. `className`, `placeholder`, `required`, `onBlur` etc. _Note: we recommend using the separate `disabled` prop instead of `inputProps.disabled`._
**onChangeCountry**
Type: `Function`
A handler to be called when the selected country changes. It will be passed the new country iso2 code e.g. "gb" for UK.
**onChangeErrorCode**
Type: `Function`
A handler to be called when the number validation error changes. It will be passed the new error code (or `null`).
**onChangeNumber**
Type: `Function`
A handler to be called when the number changes. It will be passed the new number.
**onChangeValidity**
Type: `Function`
A handler to be called when the number validity changes e.g. to true/false. It will be passed the new isValid boolean.
**usePreciseValidation**
Type: `Boolean`, Default: `false`
By default we use `isValidNumber` for validation, but if you'd rather use `isValidNumberPrecise` you can set this to `true`.
## Accessing Instance Methods
You can access all of the plugin's [instance methods](https://github.com/jackocnr/intl-tel-input/blob/master/README.md#instance-methods) (`setNumber`, `setCountry`, `setPlaceholderNumberType` etc) by passing a ref into the IntlTelInput component (using the `ref` prop), and then calling `ref.current.getInstance()` e.g. `ref.current.getInstance().setNumber(...);`. See the [Set Number demo](https://github.com/jackocnr/intl-tel-input/blob/master/react/demo/set-number/SetNumberApp.tsx) for a full example. You can also access the input DOM element in a similar way: `ref.current.getInput()`.
## Accessing Static Methods
You can access all of the plugin's [static methods](https://github.com/jackocnr/intl-tel-input/blob/master/README.md#static-methods) by importing `intlTelInput` from the same file as the react component e.g. `import { intlTelInput } from "intl-tel-input/react"` (note the lower case "i" in "intlTelInput"). You can then use this as you would with the main plugin e.g. `intlTelInput.getCountryData()` or `intlTelInput.utils.numberType` etc.
## Troubleshooting
**Error when toggle presence of IntlTelInput component**
Error message: `Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.`
Solution: wrap the component in a div e.g.
```js
{showIntlTelInput && (
<div>
<IntlTelInput />
</div>
)}
```
