# React Native AutoLink [![Version][version-image]][package-url] [![Downloads][downloads-image]][package-url] [![Build Status][build-image]][build-url] [![License][license-image]][license-url] Auto-Linking component for React Native. Parses text and wraps URLs, phone numbers, emails, social handles, hashtags, and more with Text nodes and onPress handlers. **New in v4**: Autolink any pattern using [custom regex matchers](#custom-matchers) and click handlers! Thanks @lafiosca! ## Installation ```shell npm i react-native-autolink ``` ## Usage Simply import the library and enable the link types you want to auto-link: ```javascript import Autolink from 'react-native-autolink'; const MyComponent = () => ( ); ``` ## Props - [`component?`](#component) - [`email?`](#email) - [`hashtag?`](#hashtag) - [`linkProps?`](#linkprops) - [`linkStyle?`](#linkstyle) - [`matchers?`](#matchers) - [`mention?`](#mention) - [`onPress?`](#onpress) - [`onLongPress?`](#onlongpress) - [`phone?`](#phone) - [`renderLink?`](#renderlink) - [`renderText?`](#rendertext) - [`showAlert?`](#showalert) - [`stripPrefix?`](#stripprefix) - [`stripTrailingSlash?`](#striptrailingslash) - [`text`](#text) - [`textProps?`](#textprops) - [`truncate?`](#truncate) - [`truncateChars?`](#truncatechars) - [`truncateLocation?`](#truncatelocation) - [`url?`](#url) - [`useNativeSchemes?`](#usenativeschemes) **Note:** All other props (e.g. `numberOfLines`, `style`, etc.) will be passed through to the container component, which is either `Text` (default) or a custom component supplied to the `component` prop. ### `component` | Type | Required | Default | Description | | ------------------- | -------- | ------- | ---------------------------------------------------- | | React.ComponentType | No | `Text` | Override the component used as the output container. | ```js ``` ### `email` | Type | Required | Default | Description | | ------- | -------- | ------- | ------------------------------------------ | | boolean | No | `true` | Whether to link emails (`mailto:{email}`). | ```js ``` ### `hashtag` | Type | Required | Default | Description | | ----------------- | -------- | ------- | ---------------------------------------------------------------------------------------------------------------------------- | | boolean or string | No | `false` | Whether to link hashtags to supplied service.

Due to permissions requirements on iOS and upcoming changes on Android, this feature was removed and instead, services will be linked to the web versions by default. Use the `useNativeSchemes` prop to enable native app linking or use the `onPress` and/or `matchers` props to provide your own custom logic for linking and opening apps. ## Custom Matchers Custom matchers allow for complete customization of Autolink. You can match text based on a custom regular expression, supply custom `onPress` and `onLongPress` handlers, custom link styles, and even custom functions for creating the text and/or URL for the match. Custom matchers are particularly useful for matching other types of data that aren't supported out-of-the-box (e.g. international phone numbers) and for mixing internal app navigation links with standard external links within the same block of content. Check out the section below for a few [ready-to-go custom matchers](#available-matchers). ```ts interface CustomMatcher { /* Regular expression pattern to match/link user-specified patterns */ pattern: RegExp; /* Custom press handler for links of this type */ onPress?: (match: CustomMatch) => void; /* Custom long-press handler for links of this type */ onLongPress?: (match: CustomMatch) => void; /* Custom styling for links of this type */ style?: StyleProp; /* Custom type/identifier for use with match.getType() */ type?: string; /* Custom function for extracting link text using regex replacer args */ getLinkText?: (replacerArgs: ReplacerArgs) => string; /* Custom function for extracting link URL using regex replacer args */ getLinkUrl?: (replacerArgs: ReplacerArgs) => string; } ``` The `ReplacerArgs` type supplied to `getLinkText` and `getLinkUrl` is an array containing the variadic arguments passed to a replacer function as provided to `String.replace`. Essentially, element 0 is the entire matched link, and elements 1 through N are any captured subexpressions. More details can be found [in the documentation on MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace#specifying_a_function_as_a_parameter). The `CustomMatch` class supplied to `onPress` and `onLongPress` (or their non-custom-matcher companions above) includes a few methods that can be useful as well, e.g. `getMatcher()` to return the `CustomMatcher` object and `getReplacerArgs` to return the same array discussed above. ### Custom Matcher Usage When using the built-in link handling, the `getLinkUrl` function can be provided to determine the URL to which the link should navigate. Alternatively the `onPress` function will bypass that entirely, allowing the user to provide custom handling specific to this link type, e.g. for navigating within the application. The following hypothetical example handles custom @-mention links of the format `@[Name](userId)`, navigating to a user profile screen: ```js `@${replacerArgs[1]}`, onPress: (match) => { navigate('userProfile', { userId: match.getReplacerArgs()[2] }); }, }, ]} /> ``` ### Available Matchers A few custom matchers (e.g. `LatLngMatcher`, `IntlPhoneMatcher`, `PhoneMatchersByCountry`) are already included and available for use. They're just objects so they're easily customizable too! PRs are welcome for additional custom matchers that could be useful to the community. ```js import { Autolink, LatLngMatcher } from 'react-native-autolink'; ; // Or customize the matcher const MyLatLngMatcher = { ...LatLngMatcher, onPress: () => alert('LatLng pressed!') }; ; ``` ## Supported By
