Integrate JavaScript SDK v1.1 with your Svelte app

  •   3 minute read  

This guide will help you integrate RudderStack with your Svelte app using the RudderStack JavaScript SDK. On successful integration, you can track and send real-time user events to your preferred destinations via RudderStack.

To set up the event stream on your Svelte app, you need to perform the following steps:

  1. Integrate the JavaScript SDK with your Svelte app and set up the tracking code
  2. Configure a destination in RudderStack
  3. Deploy your Svelte app and verify the events

Prerequisites

This guide assumes you have installed and set up your Svelte app. Refer to the Svelte blog post for more information.

Integrating the JavaScript SDK with your Svelte app

Integrating the JavaScript SDK with your Svelte app involves the following steps:

  1. Creating a JavaScript source in RudderStack
  2. Installing and configuring the JavaScript SDK in your Svelte app

Creating a JavaScript source in RudderStack

The RudderStack JavaScript source is required track the events from your Svelte app. Follow these steps to set it up in your RudderStack dashboard:

  1. Note the data plane URL in your RudderStack dashboard. This is required to set up the JavaScript SDK in your Svelte app.
Data plane URL
  1. Click the Sources button in the left navigation bar and select New Source to create a source. Under Sources, select Event Streams > JavaScript.
  2. Assign a name to your source and click Continue.
  3. Your JavaScript source is now configured. Note down the write key for this source:
JavaScript source write key

Installing and configuring the JavaScript SDK in your Svelte app

To integrate RudderStack with your Svelte app and set up the tracking code, follow the steps below:

  1. In your Svelte project folder, navigate to the public folder and open index.html.
  2. Place the following script within the <head> section of the page:
<script>
                rudderanalytics = window.rudderanalytics = [];
                var methods = [
                  "load",
                  "page",
                  "track",
                  "identify",
                  "alias",
                  "group",
                  "ready",
                  "reset",
                  "getAnonymousId",
                  "setAnonymousId",
                ];
                for (var i = 0; i < methods.length; i++) {
                  var method = methods[i];
                  rudderanalytics[method] = (function (methodName) {
                        return function () {
                          rudderanalytics.push(
                                [methodName].concat(Array.prototype.slice.call(arguments))
                          );
                        };
                  })(method);
                }
          
                rudderanalytics.load("WRITE_KEY","DATA_PLANE_URL");
                //rudderanalytics.page();
  </script>
  <script src="https://cdn.rudderlabs.com/v1.1/rudder-analytics.min.js"></script>
  1. Replace WRITE_KEY and DATA_PLANE_URL with your JavaScript source write key and the data plane URL obtained in the Creating a JavaScript source in RudderStack section above.

See the sample Svelte app in the RudderStack Sample Applications repository for more information.

Configuring a destination in RudderStack

This section details the steps required to set up a destination in RudderStack, where you can send all events tracked by the JavaScript SDK you set up above.

  1. In your RudderStack dashboard, click Destinations > New destination.
  2. Choose your preferred destination from the list.
  3. Assign a name to the destination and click Continue.
  4. Select the JavaScript source configured in the above section and click Continue.
  5. Configure the destination with the required settings.
info
Optionally, you can add a user transformations to this destination to transform your events.

Deploying your Svelte app and verifying the event stream

To verify if your event stream is working correctly, deploy your Svelte app and test if the events are tracked and delivered correctly. To do so, follow these steps:

  1. From your terminal, navigate to your Svelte app’s root folder and run the following command:
npm run dev
  1. Open the local server URL(generally http://localhost:8080/) in your browser to view the app.
  2. Go to your browser’s developer tools and check the Network tab to verify if the RudderStack JavaScript SDK (rudder-analytics.js) is loaded correctly. The following image highlights this option for the Google Chrome browser:
Chrome Network tab
  1. Click the various links or pages in your app for RudderStack to track these actions.
  2. Go to the Live Events tab of your JavaScript source in the RudderStack dashboard to check if the events are tracked. Note that you may face a minor delay before the events start showing up in your dashboard.
  3. Go to your destination to verify if the events are received successfully.
