Project setup | JavaScript

Create a project

We are going to create a simple HTML page that contains our JavaScript file, which will handle our WebSocket connection. First, create a directory for your next project:

mkdir deriv-websocket-demo

Navigate to the deriv-websocket-demo folder:

cd deriv-websocket-demo

Next, create the required files as you see below:

touch index.html index.css index.js

tip

We suggest using Visual Studio Code with Live Server Extension enabled. This will help you a lot with implementations.

Now, open the index.html file or use the Live Server Extension.

Now, change the content of the files using the following approach:

index.js
console.log('we will create our websocket connection here');

index.html
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Deriv HTML JS Demo</title>
  </head>
  <body>
    <h2>Deriv WebSocket API demo</h2>
    <script src="index.js" async defer />
  </body>
</html>

After adding the content, we can run the application by simply executing the index.html file or by using the Live Server Extension. When running your app, see in the console if the console.log is appearing. Then you know that the JavaScript file is working so that the websocket connection can be implemented properly.

For setting up the Deriv websocket, you can proceed to the WebSocket connection page.
