Create a Youtube-integrated application using React Native


While building certain types of mobile apps, you might need to have media files displayed in the app. In this tutorial, we will see how to integrate media from YouTube into our mobile apps.

What we’ll build

We will build a simple mobile app using React Native called OurTube which will pull videos from the new trailers on Rotten Tomato YouTube channel via the Youtube API and display them to the user. After displaying, we should also be able to tap on a video and have it play inside the app.


A basic understanding of React and React Native is required for this tutorial.

Getting started

Youtube is a video sharing website and it allows users to upload, rate, like, dislike, comment on videos and a lot more. Youtube also allows users to live stream videos. Youtube is also used widely for video blogging, educational purposes, movies, and trailers, and so on. With the Youtube API, users can find, watch, and manage content on YouTube. It also allows you to add YouTube functionality to your website and mobile apps.

Obtaining your YouTube API key

To get started, the first step is to obtain our developer API key from the developer console. If you prefer a video tutorial, you can find a detailed video tutorial on how to obtain your developer API keys for YouTube here.

After obtaining your API key that should look like AIzaSy****DjoCmWdzH*****cZYjOVg8o******, we require the playlist ID we would like to fetch. To get the playlist ID:

  • Go to Rotten Tomatoes TV channel YouTube page -> New Trailers Playlist
  • Copy the URL from the address bar e.g <a href="https://www.youtube.com/playlist?list=PLTovKDoAy18KZ6sUQcmK2RDQeYkm2xUNt" target="_blank">https://www.youtube.com/playlist?list=PLTovKDoAy18KZ6sUQcmK2RDQeYkm2xUNt</a> and the playlist ID will be the string after the list query in the URL which is PLTovKDoAy18KZ6sUQcmK2RDQeYkm2xUNt

Setting up our React Native project

To get started, follow the official documentation on how to set up your computer for React Native development. If you already have your computer set up, you need to initiate and create the application project.

    $ react-native init OurTube

Once that is completed, we need to compile and build the application to make sure everything is working fine.

    // For ios
    $ react-native run-ios

    // For Android
    $ react-native run-android

Configure routing using react-native-router-flux

React-native-router-flux is a simple navigation API on top of React Navigation and it allows you to declare all application routes in stack and scenes for easy management and configuration. To get started with react-native-router-flux:

    $ npm install react-native-router-flux --save

Go ahead and create a route file and configure all application routing.

    $ touch Route.js

Route.js should be in the root directory of our OurTube App and the contents will look like:

    // Route.js
    import React, { Component } from 'react';
    import {Platform} from 'react-native';
    // import components from react-native-router-flux
    import {Router, Stack, Scene} from 'react-native-router-flux';
    // import our screens as components 
    import Home from './screens/Home';
    import WatchVideo from './screens/Video';
    export default class Routes extends Component<{}> {
      render() {
              <Stack key="root">
                <Scene key="home" component={Home} title="Playlist Videos" />
                <Scene key="watchvideo" component={WatchVideo} title="View Video"/>

The Router is the main routing component while a Stack is a group of Scenes with it’s own navigator, so you can have multiple stacks for navigating. A Scene is the basic routing component for the main router and all Scene components require a key prop that must be unique and a key prop is used to call the screen transition and must be unique to all screens. We have created two scenes called home and watchvideo. The scenes will be called as actions in our Home and Video screens. More information can be found in the official documentation of React Native Router Flux. Update App.js file to look like:

    // App.js
    import React, { Component } from 'react';
    import {
    } from 'react-native';
    import Routes from './Route';
    export default class App extends Component<{}> {
      render() {
        return (
          <View style={styles.container}>
    const styles = StyleSheet.create({
      container : {
        flex: 1,

Creating UI components

React Native offers inbuilt UI components and we’ll be leveraging these inbuilt components. We will make use of components such as the FlatList, Text, and so on. Let’s go ahead to create our project directories and files:

    $ mkdir screens && cd screens
    $ touch Home.js Video.js

``js // screens/Home.js import React, { Component } from ‘react’; import { StyleSheet, SafeAreaView, FlatList, Text, TouchableOpacity } from ‘react-native’; import {Actions} from ‘react-native-router-flux’; const MAX_RESULT = 15; const PLAYLIST_ID = “PLScC8g4bqD47c-qHlsfhGH3j6Bg7jzFy-”; const API_KEY = “”; export default class Home extends Component<{}> {

    Actions.watchvideo({video_url: video_url});
  componentWillMount() {
  fetchPlaylistData = async () => {
    const response = await fetch(`https://www.googleapis.com/youtube/v3/playlistItems?playlistId=${PLAYLIST_ID}&maxResults=${MAX_RESULT}&part=snippet%2CcontentDetails&key=${API_KEY}`);
    const json = await response.json();
    this.setState({ videos: json['items']});
  constructor(props) {
    this.state = {
      videos: [],
  render() {
    const videos = this.state.videos;
    return (
      <SafeAreaView style={styles.safeArea}>
              keyExtractor={(_, index) => index.toString()}
                ({item}) => 
                    onPress={() => this.watchVideo(item.contentDetails.videoId)}
const styles = StyleSheet.create({
  safeArea: {
    flex: 1,
    backgroundColor: '#fff'
  demacate: {
    borderBottomColor: 'blue',
    borderBottomWidth: 2,
  item: {
    padding: 10,
    fontSize: 12,
    height: 44,

The first thing we do in the `Home.js` file is to import all the necessary components to build the home screen. Like the variable names imply, `MAX_RESULT` is the number of videos we want to return from the youtube API, `PLAYLIST_ID` is a string of the youtube playlist we want to fetch and `API_KEY` will hold our Youtube API access key.

The `home()` and `watchVideo()` functions will call navigation actions that allow us to navigate from page to page. The `fetchPlaylistData()` is an asynchronous function that allows us to fetch data from the Youtube API and `componentWillMount()` allows us to fetch the async data after the screen is rendered. 

The response data is converted to JSON and stored in the videos state and will be passed to our component during rendering. 

In the `render()` we define a prop that holds data fetched such as video id from our Youtube API and we pass it to the videos page as a `video_url` prop so we don't have to do a network fetch to get the same data on the next screen. 

Our `render()` function renders the screen and we use the SafeAreaView component to handle the screens of newer devices such as the iPhone X, XR and higher so the screen doesn't overlap. We use the `Flatlist` component to render our data from the `videos` state using the `renderItem` prop.

    // screens/Video.js
    import React, { Component } from 'react';
    import { StyleSheet, SafeAreaView, View, WebView } from 'react-native';
    import {Actions} from 'react-native-router-flux';
    export default class WatchVideo extends Component<{}> {

      constructor(props) {
      render() {
        return (
          <SafeAreaView style={styles.safeArea}>
                  source={{ uri: "https://www.youtube.com/embed/"+this.props.video_url}}
    const styles = StyleSheet.create({
      safeArea: {
        flex: 1,
        backgroundColor: '#fff'

In the Video.js file, we also import all the necessary components to build our interface and likewise, create routing actions so we can navigate back to our home screen. In the render() function, the data we stored in the video_url props is accessed and rendered using the Webview video component. The component is customizable and allows us to define the URL source, loaders, and so on.

Building our app

To build and compile our code on iOS:

    $ react-native run-ios

To build and compile our code on Android:

    $ react-native run-android

After build is successful, your application should look like:

  • Home Screen
  • Video Screen


The YouTube API is robust and allows us to watch videos, get video metadata, and so on. The data can be integrated with any mobile development framework and as seen in OurTube app using React Native. OurTube app is in a simple version right now, but you can go ahead to add some more functionalities such as liking and disliking videos, reporting comments, and so on by reading the Google Developer guide for Youtube in order to build complex and robust applications. The codebase to this tutorial is available in a public GitHub repository. Feel free to play around with it.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

  • slug - a string, the slug for the url of the post you want

We'll show examples throughout of these default examples while showcasing all the specific post types.

Creating a photo post

Creating a photo post supports a bunch of different options plus the described default options * caption - a string, the user supplied caption * link - a string, the "click-through" url for the photo * source - a string, the url for the photo you want to use (use this or the data parameter) * data - a list or string, a list of filepaths or a single file path for multipart file upload

#Creates a photo post using a source URL
client.create_photo(blogName, state="published", tags=["testing", "ok"],

#Creates a photo post using a local filepath
client.create_photo(blogName, state="queue", tags=["testing", "ok"],
                    tweet="Woah this is an incredible sweet post [URL]",

#Creates a photoset post using several local filepaths
client.create_photo(blogName, state="draft", tags=["jb is cool"], format="markdown",
                    data=["/Users/johnb/path/to/my/image.jpg", "/Users/johnb/Pictures/kittens.jpg"],
                    caption="## Mega sweet kittens")

Creating a text post

Creating a text post supports the same options as default and just a two other parameters * title - a string, the optional title for the post. Supports markdown or html * body - a string, the body of the of the post. Supports markdown or html

#Creating a text post
client.create_text(blogName, state="published", slug="testing-text-posts", title="Testing", body="testing1 2 3 4")

Creating a quote post

Creating a quote post supports the same options as default and two other parameter * quote - a string, the full text of the qote. Supports markdown or html * source - a string, the cited source. HTML supported

#Creating a quote post
client.create_quote(blogName, state="queue", quote="I am the Walrus", source="Ringo")

Creating a link post

  • title - a string, the title of post that you want. Supports HTML entities.
  • url - a string, the url that you want to create a link post for.
  • description - a string, the desciption of the link that you have
#Create a link post
client.create_link(blogName, title="I like to search things, you should too.", url="https://duckduckgo.com",
                   description="Search is pretty cool when a duck does it.")

Creating a chat post

Creating a chat post supports the same options as default and two other parameters * title - a string, the title of the chat post * conversation - a string, the text of the conversation/chat, with diablog labels (no html)

#Create a chat post
chat = """John: Testing can be fun!
Renee: Testing is tedious and so are you.
John: Aw.
client.create_chat(blogName, title="Renee just doesn't understand.", conversation=chat, tags=["renee", "testing"])

Creating an audio post

Creating an audio post allows for all default options and a has 3 other parameters. The only thing to keep in mind while dealing with audio posts is to make sure that you use the external_url parameter or data. You cannot use both at the same time. * caption - a string, the caption for your post * external_url - a string, the url of the site that hosts the audio file * data - a string, the filepath of the audio file you want to upload to Tumblr

#Creating an audio file
client.create_audio(blogName, caption="Rock out.", data="/Users/johnb/Music/my/new/sweet/album.mp3")

#lets use soundcloud!
client.create_audio(blogName, caption="Mega rock out.", external_url="https://soundcloud.com/skrillex/sets/recess")

Creating a video post

Creating a video post allows for all default options and has three other options. Like the other post types, it has some restrictions. You cannot use the embed and data parameters at the same time. * caption - a string, the caption for your post * embed - a string, the HTML embed code for the video * data - a string, the path of the file you want to upload

#Creating an upload from YouTube
client.create_video(blogName, caption="Jon Snow. Mega ridiculous sword.",

#Creating a video post from local file
client.create_video(blogName, caption="testing", data="/Users/johnb/testing/ok/blah.mov")

Editing a post

Updating a post requires you knowing what type a post you're updating. You'll be able to supply to the post any of the options given above for updates.

client.edit_post(blogName, id=post_id, type="text", title="Updated")
client.edit_post(blogName, id=post_id, type="photo", data="/Users/johnb/mega/awesome.jpg")

Reblogging a Post

Reblogging a post just requires knowing the post id and the reblog key, which is supplied in the JSON of any post object.

client.reblog(blogName, id=125356, reblog_key="reblog_key")

Deleting a post

Deleting just requires that you own the post and have the post id

client.delete_post(blogName, 123456) # Deletes your post :(

A note on tags: When passing tags, as params, please pass them as a list (not a comma-separated string):

client.create_text(blogName, tags=['hello', 'world'], ...)

Getting notes for a post

In order to get the notes for a post, you need to have the post id and the blog that it is on.

data = client.notes(blogName, id='123456')

The results include a timestamp you can use to make future calls.

data = client.notes(blogName, id='123456', before_timestamp=data["_links"]["next"]["query_params"]["before_timestamp"])

Tagged Methods

# get posts with a given tag
client.tagged(tag, **params)

Using the interactive console

This client comes with a nice interactive console to run you through the OAuth process, grab your tokens (and store them for future use).

You'll need pyyaml installed to run it, but then it's just:

$ python interactive-console.py

and away you go! Tokens are stored in ~/.tumblr and are also shared by other Tumblr API clients like the Ruby client.

Running tests

The tests (and coverage reports) are run with nose, like this:

python setup.py test
