Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

import React, { View, Text, Linking } from 'react-native';
import urlParse from 'url-parse';

class App extends Component {
    componentDidMount() {
        // Handling Deep Linking
        const deepLinkUrl = Linking.getInitialURL().then((url) => {
            console.log(`Deep Link URL: ${url}`);
            if (url) {
                const parsedUrl = urlParse(url, true);

var vFOV = this.camera.fov * Math.PI / 180;;
var h = 2 * Math.tan( vFOV / 2 ) * this.camera.position.z;
var aspect = width / height;
var w = h * aspect;

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus
