Frequently Asked Questions
How do I open a live web preview in the IDE?▼
To open a live web preview, start your local development server (e.g., 'npm run dev') and use the IDE’s preview feature to open the app in a new tab or panel.
Can I interact with the web app in the preview?▼
Yes, you can interact with the web app in the preview, such as clicking buttons or filling forms, just as you would in a browser.
Does the preview support all web technologies?▼
The preview supports most standard web technologies, but compatibility may vary based on the IDE’s rendering engine and the specific technologies used in the app.
How does the preview handle authentication?▼
Authentication in the preview typically works as it would in a browser, but you may need to log in separately if the preview doesn’t share sessions with your system browser.
Can I debug the web app within the preview?▼
Debugging capabilities in the preview may be limited compared to a full browser’s DevTools, but some IDEs offer integrated debugging tools for the preview.
Is the preview available for all programming languages?▼
The preview is primarily designed for web applications, so it supports languages and frameworks that run in a browser, such as JavaScript, HTML, and CSS.
How does the preview handle local storage and cookies?▼
Local storage and cookies are typically managed within the preview’s isolated environment, similar to a browser tab, but may not persist across sessions.
Can I share the preview with others?▼
Sharing the preview directly may not be supported, but you can share the locally hosted app’s URL if it’s accessible on the network.
Does the preview work with HTTPS?▼
The preview can work with HTTPS if the local server is configured to use HTTPS, but you may need to handle certificate warnings or trust the local certificate.
How do I configure the preview settings?▼
Preview settings can usually be configured in the IDE’s preferences or settings panel, where you can adjust options like the default browser or preview behavior.
