A library of customized React Native/React Native Web components

by React Native Example

React Native Web UI Components

React Native Web UI Components is a library of customized React Native/React Native Web components for mobile and web UI. This library is used by React Native Web Jsonschema Form.

Setup

React Native Web UI Components was created to facilitate the development of write once, run anywhere web and mobile apps. In order to accomplish that, this library heavily based on React Native, React Native Web and Expo.

Requirements

First you need to install react ^16.8.3 (this library uses react-hooks).

yarn add react react-dom react-router react-router-dom react-router-native expo

Expo uses a custom version of react-native and therefore you need to check what is the React Native repository for the Expo version you're using. For Expo v33.x.x you'd run:

yarn add https://github.com/expo/react-native/archive/sdk-33.0.0.tar.gz

If your project is also being used for web, please install React Native Web. Make sure your babel/webpack build replace all react-native imports with react-native-web (details here). If you used React Create App, aliasing is already taken care off for you.

yarn add react-native-web

Installation

First, install the library.

yarn add react-native-web-ui-components

Mobile

  1. You need to import the fonts. First, download the font files and add them to src/assets/fonts in your project. Then, make sure you import the font at App.js.
  2. Wrap your entry screen with UIProvider. Note that UIProvider must be within Router.
import React from 'react';
import { StyleSheet } from 'react-native';
import { UIProvider, Router, Switch } from 'react-native-web-ui-components';
import { createMemoryHistory } from 'history';

const history = createMemoryHistory();

const theme = {
  input: {
    focused: StyleSheet.create({
      border: {
        borderColor: 'yellow',
      },
    }),
  },
};

class App extends React.Component {
  state = {
    fontLoaded: false,
  };

  async componentDidMount() {
    await Font.loadAsync({
      'Lucida Sans': require('./src/assets/fonts/Lucida-Sans.ttf'),
      'Lucida Sans Bold': require('./src/assets/fonts/Lucida-Sans-Bold.ttf'),
    });
    this.setState({ fontLoaded: true });
  }

  render() {
    const { fontLoaded } = this.state;
    if (fontLoaded) {
      return (
        <Router history={history}>
          <Switch history={history}>
            <UIProvider theme={theme} amp={false}>
              <AMPProvider 
              <EntryScreen {...props} />
            </UIProvider>
          </Switch>
        </Router>
      );
    }
    return null;
  }
}

export default App;

Web

This library was built with Google's new standard Accelerated Mobile Page in mind. Although most components exported by this library are AMP compatible by default, some components will have different implementations for AMP and non-AMP pages. This usually happens when the usabability would be degraded by complying with AMP requirements. If you're using server-side rendering (SSR), set amp to true for AMP pages.

  1. Wrap your entry screen with UIProvider. Note that UIProvider must be within Router.
import React from 'react';
import { StyleSheet } from 'react-native';
import { UIProvider, Router, Switch } from 'react-native-web-ui-components';
import { createMemoryHistory } from 'history';

const history = createMemoryHistory();

const theme = {
  input: {
    focused: StyleSheet.create({
      border: {
        borderColor: 'yellow',
      },
    }),
  },
};

const App = props => (
  <Router history={history}>
    <Switch history={history}>
      <UIProvider theme={theme} amp={false}>
        <AMPProvider 
        <EntryScreen {...props} />
      </UIProvider>
    </Switch>
  </Router>
);

export default App;

Usage

React Native Web UI Components was developed with file size in mind and therefore exports individual components without the need of using the entire library.

import Autocomplete from 'react-native-web-ui-components/Autocomplete';

Or using babel-plugin-lodash. This can be done by updating lodash config in .babelrc.

{
  "plugins": [
    ["lodash", { "id": ["lodash", "react-native-web-ui-components"] }]
  ]
}

After that, you can do imports like below without actually include the entire library content.

import { Autocomplete } from 'react-native-web-ui-components';

Class Names

While mobile components are indiferent to the className property, that is very useful for the web. React Native Web components no longer accept class names but for convenience, this library accepts the className property for all exported components. Please note that class names are converted into data-class attribute.

import React from 'react';
import { Row } from 'react-native-web-ui-components';

// You must use the Helmet export by this library to avoid conflicts.
import Helmet, { style } from 'react-native-web-ui-components/Helmet';

const MyComponent = () => (
  <React.Fragment>
    <Helmet>
      <style>
        {`
          [data-class~="MyComponent__Row"] {
            width: calc(100% - 20px);
          }
        `}
      </style>
    </Helmet>
    <Row className="MyComponent__Row" />
  </React.Fragment>
);

Components

Alert

Opens an Alert popup. This library uses React Modal to display modals for web.

Autocomplete

Column

Column is a View with flexDirection: "column" that follows Bootstrap's grid system. You can define the percentage of the width that should be used in different screen sizes. For example:

<Row>
  <Column xs={12} sm={4} md={3} lg={2} style={{ backgroundColor: 'red', height: 25 }} />
  <Column xs={12} sm={4} md={3} lg={2} style={{ backgroundColor: 'green', height: 25 }} />

Helmet

This library exports React Helmet. For mobile, Helmet won't do anything.

import React from 'react';
import { Row } from 'react-native-web-ui-components';

// You must use the Helmet export by this library to avoid conflicts.
import Helmet, { style } from 'react-native-web-ui-components/Helmet';

const MyComponent = () => (
  <React.Fragment>
    <Helmet>
      <style>
        {`
          [data-class~="MyComponent__Row"] {
