Unlock Real-Time Communication with WebSockets on Appery.io

Introduction to WebSockets with Appery.io

Have you ever wondered how apps send updates in real-time? The magic happens with WebSockets. Today, we’ll show you how to add WebSockets to your apps using Appery.io. This low-code app-building platform makes it easy to create complex apps quickly. Note that this post supports our comprehensive video tutorial and if you are interested in details, you are welcome to watch it.

By following the steps below, you can easily enhance your app with real-time communication features using WebSockets and Appery.io. Exciting, right? Let’s get started!

Setting Up Your App

First, create an empty app in Appery.io. Then, go to the Catalog of Appery.io plugins and select the WebSocket Example plugin.

Before importing it, you can click the link to open its documentation page. You’ll see it contains the code for the WebSocket server. This server needs to be run somewhere. While real applications may use Amazon or Azure, we’ll use CodeSandbox for testing.

Using CodeSandbox

1. Create a new Devbox.

2. Select Node.js Server from the list of backend frameworks.

3. Name your Devbox and set its visibility to “Public”.

4. Install two npm modules: `express` and `socket.io`.

Now, let’s move to the next step.

Setting Up Your WebSocket Server

Copy the server code from the documentation page and paste it into your `index.js` file in CodeSandbox. If everything is correct, the server should start successfully.

Back to Appery.io

Return to the Appery.io project and click Import selected plugins with the WebSocket Example plugin checked. This plugin helps you integrate WebSockets into your app. But first, let’s test it.

Testing Your App

Go to the Project > Routing section and set “WebSocketScreen” as the default page.

Next, navigate to TypeScript > WebSocket and specify the URL of your WebSocket server obtained from CodeSandbox.

Now, run your app in different browsers like Google Chrome, Firefox, and Edge. Enter a test message and click the “Send” button.

Ready! The message should be delivered to all clients in real-time.


Now you’ve seen how to add Websockets to your apps using Appery.io. This post is a companion piece to our detailed video tutorial. The demo app isn’t a finished product but provides a solid template for building your own real-time communication features. Give it a try and unlock powerful networking capabilities in your applications!

Development Tip: Use Server Code Plug-ins and Snippets for Quicker Coding


Using Server Code snippets and plug-ins are a great way to save time when making server scripts. Instead of digging through the Server Code documentation, you can simply choose one of the snippets located on the right side of the screen in script editor mode. The set of snippets provided by the Server Code API are the most common, but if you think of other useful snippets, let us know and we’ll add them to the list.

Server Code plug-ins are another way to save time when implementing your logic. To find Server Code plug-ins, go to the Server Code page and then to the Plugins tab. For now, there are two plug-ins. With them, you can quickly integrate with the Twilio or SendGrid API via XHR (XMLHTTPRequest). Simply click “Import” to create the server script based on the plug-in selected, and then customize it by specifying your API keys.

PayPal Secure Payments for Your Ionic & AngularJS App

paypal_logoPayPal API is one of the most popular Appery.io plug-ins, and now it’s also available for Ionic & AngularJS!

Our users have frequently requested the ability to add payments to their Ionic & AngularJS mobile apps more quickly, for example, to create an online shop. Now, with the help of this plug-in, you could build an online shop (for instance) to be used by your Ionic & AngularJS app really easily.

A few notes about the security implemented in this app:

  • Authentication with PayPal occurs via a Server Code script. It takes your PayPal app credentials and sends XHR to PayPal. The token is stored to the database.
  • By using the Secure Proxy feature, the actual token value will be substituted on the server side. This way any PayPal API can be triggered.
  • Because of the server-based authentication, sensitive data such as the client secret or token value will never be shown in the app, which eliminates the possibility of theft.

Finally, a few, more general, notes:

  • The flow implemented in this plug-in is similar to PayPal’s flow.
  • We have a PayPal API plug-in tutorial here. Check it out to configure the plug-in.
  • The plug-in is configured for a test environment, so use the PayPal guide too see what you need to do when going live.
