"It doesn't work" gives it nothing to go on. It needs the error message. Where to find it:
- Browser: right-click > Inspect > Console tab. Red lines are errors.
- Network tab, if data doesn't load: click the red request, check the status (404, 500) and the Response.
- Terminal where
npm run devruns: server errors land there, not in the browser.
Then send it:
Expected: clicking Save adds the task to the list. Actual: nothing happens. Console error: (paste exact text) Relevant code: (only the component involved)
That template alone will change the quality of answers a lot.
