88-113: Implement the worker inactivity timeout mechanism effectively.The changes implement the inactivity timeout mechanism effectively, with clear setup and reset logic. However, ensure that the logging of worker termination is appropriate and consider adding more detailed logs for debugging purposes.

1-1: Ensure consistent import usage.Consider grouping similar imports together for better readability.
30-38: Correct the error in mockingconsole.logand verify worker shutdown logic.The test fails due to incorrect mocking of
console.log. Ensure that the mock setup is done before the page interactions that would trigger the logs.- const logs = await page.evaluate(() => console.log.mock.calls) + const logs = await page.evaluate(() => window.console.log.mock.calls)Additionally, validate that the worker shutdown is triggered correctly by the inactivity timeout.

30-42: Ensure proper simulation of worker inactivity in the test case.The test case is designed to verify the automatic shutdown of a worker after 1 second of inactivity. However, the test does not explicitly ensure that the worker remains inactive. Consider adding a check or a mock to ensure no messages are sent to the worker during the wait period to accurately simulate inactivity.
+ // Ensure no messages are sent to the worker during the inactivity period. + vi.spyOn(page, 'send').mockImplementation(() => {}) await new Promise(resolve => setTimeout(resolve, 1500))Verification successful
The test case properly simulates worker inactivity.
The test case does not show any interactions with the worker during the inactivity period, aside from capturing console logs, which do not interfere with the worker's state. Therefore, the test case accurately simulates worker inactivity.
- Instances of
page.on('console', ...)are used solely for capturing logs and do not interact with the worker.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Search for any interactions with the worker during the supposed inactivity period. # Expect: No interactions found. # Search for any message sending to the worker during the inactivity period. rg --type ts $'page.emit|page.send'Length of output: 36

Implements automatic shutdown of workers after 1 second of inactivity and updates documentation to reflect this new feature.
src/plugins/unplugin.tsto automatically terminate workers after 1 second of inactivity. This includes initializing and resetting the inactivity timer upon receiving a message from the worker.README.mdto include information about the automatic worker shutdown feature under the "Features" and "Usage" sections, providing users with insights on how this mechanism works and its benefits.test/e2e.spec.tsby adding a new test case to verify that workers are indeed shut down after 1 second of inactivity, ensuring the feature works as expected across different scenarios.For more details, open the Copilot Workspace session.
