For web and Flutter apps, a web console and\n[Lighthouse](https://developer.chrome.com/docs/lighthouse/overview)\nare directly integrated into the workspace. Flutter apps offer Android and web\npreviews to spot-check and test your app while you code.\n\nRicher, breakpoint-based debugging is also available for most common languages,\nthrough the built-in Debug Console, and extensible with [Debugger extensions\nfrom OpenVSX](https://open-vsx.org/?category=Debuggers). For\nbreakpoint-based debugging of your frontend web code (like JavaScript), you can\ncontinue using your browser's built-in developer tools, like\n[Chrome's DevTools](https://developer.chrome.com/docs/devtools).\n\nPreview your app\n\nFirebase Studio includes\n[in-workspace app previews](/docs/studio/preview-apps) for web apps (Chrome)\nand Flutter apps (Android, Chrome). The\nAndroid and Chrome previews support hot reload and hot refresh, and offer full\nemulator capabilities.\n\nTo learn more about Firebase Studio previews, see\n[Preview your app](/docs/studio/preview-apps).\n\nUse the integrated web console for web previews\n\nThe integrated web console helps you diagnose issues in your app directly\nfrom the web preview. You can access the web console in the\nFirebase Studio web preview panel by expanding the bar at the bottom.\n\nNote that this feature is experimental and isn't enabled by default. To\nturn it on, follow these steps, and [share your\nfeedback](/support/troubleshooter/studio) after\nyou've tried it out:\n\n1. Add the web console to your Firebase Studio workspace:\n\n 1. Open **Settings** by clicking settings or pressing `Ctrl + ,` (on Windows/Linux/ChromeOS) or `Cmd + ,` (on MacOS).\n 2. Find the **Firebase Studio: Web Dev Tools** setting and enable it. If you're editing your `settings.json` file directly, you can add `\"IDX.webDevTools\": true`.\n 3. Refresh your browser window to reload your Firebase Studio workspace.\n2. Open the web preview in Firebase Studio: Open the command palette\n (`Cmd+Shift+P` on Mac or `Ctrl+Shift+P` on ChromeOS, Windows, or Linux)\n and select **Firebase Studio: Show Web Preview**.\n\n3. The web console panel is minimized within the web preview panel by default.\n Click the bar or drag it up to expand it.\n\nThe web console panel in the Firebase Studio web preview works\nsimilarly to other consoles, such as the one available in\n[Chrome DevTools](https://developer.chrome.com/docs/devtools):\n\n- JavaScript errors and `console.log` statements will appear there as you use your app.\n - For errors and warnings, you also have the option to get assistance from Gemini by selecting the **Understand this error** button at the right of the error message.\n- You can evaluate arbitrary JavaScript in the context of your web preview by using the prompt bar at the bottom.\n\nRun Lighthouse for web previews\n\n[Lighthouse](https://developer.chrome.com/docs/lighthouse/overview)\naudits your app based on the specific audit categories you select, and returns\na report with findings and suggestions. You can run Lighthouse reports directly\nfrom the web preview in Firebase Studio.\n\n1. Open the web preview in Firebase Studio: Open the command palette\n (`Cmd+Shift+P` on Mac or `Ctrl+Shift+P` on ChromeOS, Windows, or\n Linux) select **Firebase Studio: Show Web Preview**.\n\n2. Click the\n **Run Lighthouse** icon from the web preview toolbar.\n\n3. In\n the Lighthouse panel, select the audit categories you want. You can\n choose from reports auditing [performance](https://developer.chrome.com/docs/lighthouse/performance/performance-scoring), [accessibility](https://developer.chrome.com/docs/lighthouse/accessibility/scoring),\n [conformance with best practices](https://developer.chrome.com/docs/lighthouse/best-practices/doctype), [SEO](https://developer.chrome.com/docs/lighthouse/seo/meta-description), and [Progressive Web\n App performance](https://developer.chrome.com/docs/lighthouse/pwa/load-fast-enough-for-pwa). Click **Analyze page** to generate the reports.\n\n The reports might take a few minutes to generate.\n4. After the reports appear in the Lighthouse panel, you can review the\n findings for each audit category, or switch between audit categories by\n clicking the score and category name.\n\nUse the Debug Console\n\nFirebase Studio includes the built-in Debug Console from Code OSS. Use this\nconsole to debug your app with out-of-the-box debuggers for most common\nprogramming languages, or add a debugging extension from\n[OpenVSX](https://open-vsx.org/?category=Debuggers).\n\nTo customize your debugging experience, you can also add a `.vscode/launch.json`\nfile to your workspace and specify custom launch configurations. Learn more\nabout using launch configuration files to customize debugging at\n[Visual Studio Code debug\nconfiguration](https://github.com/microsoft/vscode-docs/blob/main/docs/debugtest/debugging-configuration.md).\n\nDebug with Gemini\n\nYou can use Gemini in Firebase to help you debug your code with\nchat in your **Code** workspace\nor the App Prototyping agent.\n\nWhile Gemini can write code for you, it might sometimes also\nproduce errors. When it detects an error, it will attempt\nto fix it. If you find that it isn't able to resolve the issue given\nthe error message, you can try some of the following techniques:\n\n- **Describe the issue:** In the chat interface, describe the\n problem you're encountering as clearly and concisely as possible.\n While Gemini might have access to context like error messages\n and logs, it might not understand the full context. Describing the behavior\n along with the error message can help Gemini fix errors\n faster.\n\n- **Ask specific questions:** Don't be afraid to ask Gemini\n direct questions about your code. For example, \"What could be causing a\n null pointer exception in this function?\" or \"How can I prevent\n this race condition?\"\n\n- **Break down complex problems:** If you're dealing with a complex\n issue, break it down into smaller, more manageable parts. Ask\n Gemini to help you debug each part separately and think\n through problems step-by-step.\n\n- **Use code fences:** When sharing code snippets, use code fences\n to ensure that the code is properly formatted. This makes it easier\n for Gemini to read and understand your code.\n\n- **Iterate and refine:** Gemini may not always provide the perfect\n solution on the first try. Review the responses, ask clarifying\n questions, and provide additional information as needed.\n\n- **Avoid prompting loops:** If Gemini gets stuck in a loop or is\n unable to answer your question, try rephrasing your prompt or\n providing additional context. Sometimes, just rewording your\n question can help Gemini understand what you're asking.\n\n If rephrasing your prompt doesn't resolve the loop, try\n the following techniques:\n - **Start a new chat:** If you're using Gemini in Firebase\n chat in your Code\n workspace, start a new chat session to reset\n Gemini's context. This can help break free from any\n misconceptions or assumptions that Gemini may have made\n in the previous conversation.\n\n - **Provide counter-examples:** If Gemini is making incorrect\n assumptions, provide counter-examples to help it understand\n the correct behavior."]]
