Question 1

How do I build efficiently with Lovable?

Accepted Answer

Break big requests into small, clear prompts. Use Plan mode to outline architecture before building. Start with core features, then iterate. Use visual editor for quick tweaks (colors, sizing, text). Leverage integrations (Supabase, Stripe, Resend) via simple prompts. Check Cloud → Logs when debugging. Revert and re-prompt if needed.

Question 2

How should I structure my prompts for the best results?

Accepted Answer

Be specific and clear: 'Add a login form with email and password fields' beats 'make login.' Include context: 'This is a SaaS dashboard for task management.' Use Plan mode first to outline your architecture. Break complex features into multi-step prompts: 1) Build UI, 2) Add database, 3) Add validation. Provide examples or screenshots if possible.

Question 3

What should I do when I hit an error?

Accepted Answer

Click 'Try to fix' (free)—it scans logs, detects issues, and attempts quick fixes. Check Cloud → Logs for error details. Use Plan mode to investigate before trying again. Revert to a stable version and re-prompt with clearer instructions. Break your request into smaller prompts. Contact support@lovable.dev if stuck.

Question 4

Add a new page to your project

Accepted Answer

Prompt Lovable: 'Add a new page for [feature].' Lovable will create a new route, add it to navigation, and build the page layout. Use clear names and describe what the page should do.

Question 5

Code Modification Approach

Accepted Answer

Lovable operates in Agent mode (autonomous changes) and Plan mode (reasoning without code modification). Use Plan mode to explore ideas and investigate issues, then switch to Agent mode for implementation. For modifying existing code, be specific about what needs changing and test incrementally to catch issues early.

Question 6

Component Architecture

Accepted Answer

Lovable generates production-ready React code with proper component structure. Keep components focused (single responsibility). Pass data via props and lift state when multiple components need it. Use custom hooks to share logic. Organize components by feature, not just type. This modular approach makes your codebase scalable and maintainable.

Question 7

Dead Code Elimination

Accepted Answer

Regularly review code for unused functions, imports, and styles. Remove or refactor code that's no longer used—it creates clutter and makes debugging harder. During refactoring sessions, clean up any remnants from previous iterations. A clean codebase is easier to understand and modify.

Question 8

Preventing Duplicate Components

Accepted Answer

Before creating a new component, check if a similar one already exists in your codebase. Reuse and customize existing components rather than duplicating them. If you need a variant, refactor the component to accept props that handle both cases. This keeps your codebase lean and makes updates easier.

Question 9

Progressive Enhancement

Accepted Answer

Build core functionality first with solid foundations (database schema, authentication, basic UI). Then layer on enhancements (animations, advanced features, optimizations). This approach keeps your app stable during development and prevents breaking changes when adding complexity. Use Plan mode to design the enhancement path before Agent mode builds it.

Question 10

Refactor code

Accepted Answer

Ask Lovable to refactor specific parts of your code. Use Plan mode first to discuss the approach, then Agent mode to execute. Break complex refactors into smaller prompts for best results.

Question 11

Can I reference a specific file when chatting with Lovable?

Accepted Answer

The reference documentation doesn't detail file-specific referencing. For guidance on file selection in prompts, contact support@lovable.dev.

Question 12

Why can't Lovable access another project?

Accepted Answer

Lovable cannot access projects outside your current workspace. Ensure the project you're trying to reference is in the same workspace and that you have permission to access it. If it's in a different workspace, you'll need to switch to that workspace or remix it into your current one.

Question 13

API Integration and Network Management

Accepted Answer

When integrating external APIs, store secret keys via Cloud → Secrets or Supabase Edge Functions, never in chat or code. Use Supabase Edge Functions for backend logic that calls external APIs securely. Set reasonable timeouts and implement retry logic for unreliable networks. Log API responses to debug integration issues.

Question 14

Check Console Logs

Accepted Answer

To debug issues, open your browser's Developer Tools (F12 or Cmd+Option+I) and check the Console tab for error messages. JavaScript errors often appear there with stack traces. Lovable projects also log errors to the Cloud tab → Logs, which shows AI agent and deployment errors. Comparing browser console vs. Cloud logs helps pinpoint whether issues are client-side or infrastructure.

Question 15

Code Consistency

Accepted Answer

Maintain consistent naming conventions, component structure, and styling across your project. Follow the Lovable tech stack (React, Vite, TypeScript, Tailwind CSS, shadcn/ui, Radix UI). Reuse existing components instead of duplicating logic. Establish guardrails in Workspace knowledge (Lovable's Knowledge System) so all projects follow the same architectural rules.

Question 16

Data Flow Management

Accepted Answer

Trace data from user input through your app to the database and back. Ensure each step validates and transforms data correctly. Avoid passing unvalidated data between components. Use React state management patterns (props, context, hooks) consistently. Clear data flow makes debugging easier and prevents subtle bugs.

Question 17

Database Query Verification

Accepted Answer

Test database queries in isolation (via Supabase dashboard or Edge Functions) before integrating them into your UI. Verify that filters, joins, and aggregations return the expected data. Check Row Level Security (RLS) policies to ensure users see only what they should. Log query results during development to spot issues early.

Question 18

Deep Problem-Solving Approach

Accepted Answer

When facing a complex issue, break it into smaller parts. Investigate each component (frontend logic, database queries, API calls, external integrations) separately. Use logging and error messages to trace the exact failure point. Consider whether the issue is reproducible and how it manifests. This systematic approach narrows down the root cause faster.

Question 19

Documentation and Explanation

Accepted Answer

Document your architectural decisions, database schema, and business logic in Project knowledge (docs.lovable.dev/features/knowledge). Include naming conventions, why certain patterns were chosen, and domain terminology specific to your app. Clear documentation helps Lovable generate more accurate code and makes it easier to onboard collaborators.

Question 20

Error Fixing

Accepted Answer

Use the "Try to fix" button (free, no credits) to auto-scan logs and attempt quick fixes—it resolves about 60% of simple issues. For deeper problems, check Cloud → Logs for specific error messages, use Plan mode to investigate before Agent mode executes fixes, and break complex changes into smaller prompts. Reverting to a previous version and re-prompting with a clearer request also helps.
