Overview

Web workers in WeWeb are a great way to make your web app run smoother by moving heavy computations to background threads. This frees up the main thread, keeping everything responsive and user-friendly. Knowing how to use and handle web workers on the WeWeb platform can really boost your app's performance. This guide shows the basics of web workers, walks you through setting them up in WeWeb, and gives practical examples to get you going.

How to use web workers in WeWeb?

Step 1: Create Your Web Worker File

  1. Start by creating a new JavaScript file for your web worker. Let's call it worker.js.
  2. Inside worker.js, write the code that will run in the background. For example:
    self.onmessage = function(event) {
     const data = event.data;
     // Perform some computation
     const result = data.num1 + data.num2; 
     postMessage(result);
    }
    

Step 2: Load the Web Worker in Main Script

  1. In your main JavaScript file, create an instance of the web worker.
  2. Make sure you provide the correct path to worker.js:
    const worker = new Worker('path/to/worker.js');
    

Step 3: Set Up Message Handling

  1. Define a function to handle messages received from the web worker:
    worker.onmessage = function(event) {
     const result = event.data;
     console.log('Result from worker:', result);
    }
    
  2. Optionally, you can also handle any errors from the worker using:
    worker.onerror = function(error) {
     console.error('Error from worker:', error.message);
    }
    

Step 4: Send Messages to the Worker

  1. To send data to the web worker, use the postMessage method:
    worker.postMessage({ num1: 4, num2: 6 });
    

Step 5: Integrate Web Worker with WeWeb

  1. In WeWeb, add a custom code component where the worker initialization and interaction code can reside.
  2. Ensure the web worker file (worker.js) is uploaded to the appropriate directory within your WeWeb project.
  3. Use the WeWeb editor to add an event or trigger that invokes the worker’s message-passing functions.

Step 6: Test the Integration

  1. Publish the project within WeWeb.
  2. Test the interaction thoroughly to ensure that the web worker is functioning as expected and handle background tasks correctly.
