## React, Vue, Angular and Svelte Components
We provide React, Vue, Angular and Svelte (beta) components alongside the regular JavaScript plugin. This readme is for the JavaScript plugin. View the [React Component](https://intl-tel-input.com/docs/react-component), the [Vue Component](https://intl-tel-input.com/docs/vue-component) the [Angular Component](https://intl-tel-input.com/docs/angular-component), or the [Svelte component](https://intl-tel-input.com/docs/svelte-component).

## Docs and Examples
We have a newly updated website, where you can find [a full set of docs](https://intl-tel-input.com/docs/getting-started.html), a [live playground](https://intl-tel-input.com/playground/) where you can try out all of the options, as well as plenty of [examples](https://intl-tel-input.com/examples/validation-practical.html) of different setups.
