When working with RudderStack's JavaScript SDK, you may want to redirect users after a tracking event has been successfully sent. However, the track method does not return a promise, which can complicate the flow of your application. To handle this, you can utilize the ready method to ensure that your tracking calls are executed in the correct order before performing a redirection.

Here’s an example of how to implement this in a React application:

// Import necessary functions from RudderStack SDK
import { track, load, ready, identify } from 'rudder-sdk-js';

// Load the RudderStack SDK with your write key and data plane URL
await load(write_key, data_plane_url);

// Wait until the SDK is ready to use
await ready(async () => {
  // Identify the user with a unique hashed ID and user information
  await identify(hashedId, userInfo);

  // Track the event indicating that an order has been approved
  await track('ORDER_APPROVED');

  // After the tracking is complete, redirect the user to a new page
  history.push('/some-page');
});

In this code snippet:

  • We first load the RudderStack SDK using the load function.
  • The ready function ensures that the SDK is fully initialized before proceeding.
  • We then call identify to set user information, followed by the track method to log the event.
  • Finally, we use history.push to redirect the user once the tracking is confirmed to be complete.

This approach guarantees that the user is only redirected after the tracking event has been processed, providing a smoother user experience.
