SDS React Native Components Library

NPM package

Installation

yarn add @dfhernandez/sds-react-native-components

Needed packages

If you don't already have them on your app, yarn will install the following packages needed for usability. These packages are added as peerDependencies

• @dfhernandez/js-utilities - Contains useful js functions and shareable configurations
• @dfhernandez/sds-native-theme - Contains theme available for react native apps that use styled-components
• Styled-Components - Library to style react components
• react-native-svg - Provides SVG support to React Native on iOS and Android, and a compatibility layer for the web
• tslib - Contains all of the TypeScript helper functions. Even if your project doesn't use Typescript, you need this package for native-components to function properly

Packages considerations

If you already have those libraries on your app, then you need to make the following changes on configuration files for the package to function properly

// metro.config.js
const modules = [
  '@dfhernandez/js-utilities',
  '@dfhernandez/sds-native-theme',
  'react',
  'react-dom',
  'react-native',
  'react-native-svg',
  'styled-components',
  'tslib',
];
module.exports = (async () => {
  return {
    // ...
    resolver: {
      extraNodeModules: modules.reduce((acc, name) => {
        acc[name] = path.join(__dirname, 'node_modules', name);
        return acc;
      }, {}),
    },
    // ...
  };
})();

Now use that in webpack file

// webpack.config.js
const metroConfig = require('./metro.config');
const node_modules = path.join(__dirname, 'node_modules');

module.exports = async function (env, argv) {
  const config = await createExpoWebpackConfigAsync(env, argv);
  const { resolver } = await metroConfig;

  // We need to make sure that only one version is loaded for peerDependencies
  // So we alias them to the versions in example's node_modules
  Object.assign(config.resolve.alias, {
    ...resolver.extraNodeModules,
  });

  return config;
};

Styled-Components considerations We use a theme built for styled-components. Styled components can be used from two sources

• The one installed automatically when installing @dfhernandez/sds-react-native-components
• The one installed manually by you on your app

On the first case, components package will use the theme you set up on ThemeProvider, for your own components and the built-in components in the package. If you install styled-components on your app, components package won't use the theme you setup automatically. therefore you need to ensure only one installing of styled-components is used, the app one.

We fix this by doing the changes in metro-config.js and webpack-config.js showed previously.

React Native Svg considerations There should be only one version of react-native-svg installed, if you manually install it in your app, make sure you add it in the list of extraNodeModules so we make sure only one version is used. Otherwise it will throw an error on execution.

Usage

It relies on styled-components, so it needs a theme set for the application. Get the theme from @dfhernandez/sds-native-theme You can set the DefaultTheme as the one from sds-native-theme. Create a declaration file, name it for convention styled.d.ts

import {} from 'styled-components';
import { DefaultThemeProps } from '@dfhernandez/sds-native-theme';

declare module 'styled-components' {
  export interface DefaultTheme extends DefaultThemeProps {}
}

Now use it in your entry point component

import { lightTheme } from '@dfhernandez/sds-native-theme';

<ThemeProvider theme={lightTheme}>
  {/* <App ... /> */}
  {children}
</ThemeProvider>

This theme will apply to your components and the ones coming from sds-react-native-components

Now in your components

import { Button, Telicon } from "@dfhernandez/sds-react-native-components";

// ...

<Button onPress={handleCall} title="Call" color="#aaffcc" />
<View>
  <Telicon
    name="volume-x"
    size="xsmall"
    fill="green"
    fillSecondary="pink"
  />
</View>

Svg Files

The package already have components to treat svg xml/files. These are

• SvgFromXml - Renders an icon, it accepts a svg xml string or file (Internally calls the following two)
• SvgFromXmlString - Renders an icon, it accepts a svg xml string
• SvgFromXmlFile - Renders an icon, it accepts a svg xml file

Examples

const xml = `<svg viewBox="0 0 512 512"> <path d="M472.916..." /></svg>`;
<SvgFromXml xml={xml} size="small" fill="green" />
<SvgFromXmlString xml={xml} size="medium" fill="blue" />

// ...
import UserIcon from './app/assets/user.svg';
<SvgFromXml xml={UserIcon} size="xsmall" fill="yellow" />
<SvgFromXmlFile Xml={UserIcon} size="xlarge" fill="magenta" />

If you want to handle svg files on your own or need a different icon not included in telicon, then create a declarations.d.ts (If you already have one, then name it differently) Add this content to file

declare module '*.svg' {
  import { SvgXmlFileType } from '@dfhernandez/sds-react-native-components';
  const content: SvgXmlFileType;
  export default content;
}

Then you can import svg files this way

import UserIcon from './app/assets/user.svg';
<UserIcon width={100} height={100} fill="red" />

Use svgrrc configuration provided by @dfhernandez/js-utilities to handle how svgs are converted

const { svgrrcBaseConfig } = require('@dfhernandez/js-utilities');
module.exports = {
  ...svgrrcBaseConfig,
  native: true,
};

We use svgo to configure how svg xml should be transformed to JSX. Look for the available plugins, so you can decide what attributes should be moved. For instance, we want all colors to be converted to strings if possible (Ex. #f00 to red)

const { svgrrcBaseConfig } = require('@dfhernandez/js-utilities');
module.exports = {
  ...svgrrcBaseConfig,
  native: true,
  svgoConfig: {
    plugins: [
      { convertColors: true },
      ...
    ]
  }
};

Development

This project requires Node.js v14+ to run.

Using .nvmrc file helps to normalize node version used by all maintainers. If you are required to use version specified in this file, run these commands.

nvm use
nvm install

Use the package manager yarn v1+ to install dependencies and devDependencies.

yarn install
yarn

Create symlink Run the following command on package root folder, so you can consume on an app locally

yarn link

Watch project Build package whenever there is a change

yarn watch

Consume the package Both projects must be placed on same folder, otherwise won't work

yarn link @dfhernandez/sds-react-native-components

Considerations with packages installed

• Add package as alias in babel.config.js

// babel.config.js
const path = require('path');

module.exports = function (api) {
  api.cache(true);
  return {
    // ...
    plugins: [
      // ...
      [
        'module-resolver',
        {
          alias: {
            // ...

            // For development, we want to alias the library to the source
            // Remember we have the package folder right next to the app
            '@dfhernandez/sds-react-native-components': path.join(__dirname, '..', 'sds-react-native-components', 'src/index'),
          },
        },
      ],
    ],
  };
};

• Blacklist peerDependencies to ensure only one version of packages is used (The one from App)

// metro.config.js
const path = require('path');
const blacklist = require('metro-config/src/defaults/blacklist');
const escape = require('escape-string-regexp');

// Assuming your package folder is named "sds-react-native-components" and it's located right next to the app folder
const root = path.resolve(__dirname, '..', 'sds-react-native-components');

const modules = [
  '@dfhernandez/js-utilities',
  '@dfhernandez/sds-native-theme',
  'react',
  'react-dom',
  'react-native',
  'react-native-svg',
  'styled-components',
  'tslib',
];

module.exports = (async () => {
  return {
    projectRoot: __dirname,
    watchFolders: [root],

    resolver: {
      // We need to make sure that only one version is loaded for peerDependencies
      // So we blacklist them at the root, and alias them to the versions in example's node_modules
      blacklistRE: blacklist(
        modules.map(
          (m) =>
            new RegExp(`^${escape(path.join(root, 'node_modules', m))}\\/.*$`)
        )
      ),

      extraNodeModules: modules.reduce((acc, name) => {
        acc[name] = path.join(__dirname, 'node_modules', name);
        return acc;
      }, {}),
    },
  };
})();

Tech

Components library uses a number of open source projects to work properly:

• React.js - JavaScript library for building user interfaces.
• React Native - JavaScript library for creating native apps for Android and IOS using React.
• Typescript - Strongly typed programming language which builds on JavaScript
• NodeJs - Allows execute javascript scripts on the terminal
• Storybook - Development environment for UI components
• Luxon - library for dealing with dates and times in JavaScript (better alternative than Moment.js)
• Styled-Components - Library to style react components
• react-native-svg - Provides SVG support to React Native on iOS and Android, and a compatibility layer for the web
• create-react-native-library - CLI to scaffold React Native libraries
• @dfhernandez/sds-native-theme - React Native Theme for Styled-components
• @dfhernandez/js-utilities - Library written in js for shareable config files and common functions
