Integrate Drawer inside Stack Navigation in React Native

I wanted to use more than one navigation in a React Native app.

The documentation didn’t give a clear way to implement this.

Here is what you can do on purpose to add several types of navigation in your React Native app:




import { createStackNavigator, createDrawerNavigator } from 'react-navigation';

import * as Screens from './screens/index';

import Drawer from './components/DrawerMenu';

import getDrawerWidth from './utils/scale';



const AppStackNavigator = createStackNavigator({

  home: {

    screen: Screens.MainScreen,

  },

  about: {

    screen: Screens.AboutScreen,

  },

});



const AppNavigator = createDrawerNavigator(

  {

    home: {

       screen: AppStackNavigator,

    },

  },

  {

    contentComponent: Drawer,

    drawerWidth: getDrawerWidth,

    headerMode: 'none',

  }

);



export default AppNavigator;

JS: Parsing URL

So far, I have used the indexOf operator or regular expressions to get query string values. Today I learned how to make it easier using the URLSearchParams API:




// Assuming "?post=1234&action=edit"



let urlParams = new URLSearchParams(window.location.search);



console.log(urlParams.has('post')); // true

console.log(urlParams.get('action')); // "edit"

console.log(urlParams.getAll('action')); // ["edit"]

console.log(urlParams.toString()); // "?post=1234&action=edit"

console.log(urlParams.append('active', '1')); // "?post=1234&action=edit&active=1"



Important: Does not work in IE
