What is Lovable.dev?

Lovable.dev is an AI-powered platform that lets you create full-stack applications with minimal coding expertise. It integrates tools like Supabase, AI-driven design, and backend capabilities to make app development as easy as having a conversation.

Do’s When Using Lovable

1. Start with Authentication

• Why: Authentication serves as the foundation for most apps. Adding it later can complicate workflows.
• How: Always begin by implementing login and signup features. Example prompt:

Please add a user login and signup system using Supabase.

2. Be Specific in Your Prompts

• Why: Ambiguous instructions lead to errors and unnecessary back-and-forth.
• How: Use structured, clear prompts and break down tasks into steps. Example:

  Add a feedback page where users can:
  1. Submit feedback with a title and description.    
  2. View a list of submitted feedback.
  3. Upvote feedback items.

3. Use the Select Tool

• Why: The Select Tool helps Lovable understand exactly which components or pages you’re referring to.
• How: Highlight specific areas in your app to avoid ambiguity and ensure changes are applied correctly.

4. Include Context in Custom Knowledge

• Why: Context helps Lovable understand your app’s purpose and reduce errors, especially in larger projects.
• How: Use the Custom Knowledge section to outline:
  • App purpose
  • Key design conventions
  • Logic and features

5. Iterate Incrementally

• Why: Tackling smaller tasks allows for better testing and reduces complexity.
• How: Start with broad prompts and refine features step by step. Example:

  Add a page where users can submit and view feedback.
  Then, allow users to upvote feedback.

6. Leverage Supabase for Features

• Why: Supabase provides powerful integrations like real-time updates, storage, and Edge Functions.
• How:
  • Use Supabase Storage for file uploads.
  • Implement real-time features for live updates. Example:

Enable real-time updates for new feedback submissions and upvotes.

7. Be Descriptive in UI Design Prompts

• Why: Clear design instructions result in better UI outcomes.
• How: Use descriptive terms like “minimal,” “elegant,” or “tech-inspired.” Example:

Improve the feedback page design to be cleaner, more elegant, and fitting for a modern tech site.

8. Engage with the Community

• Why: The Lovable community provides valuable tips, inspiration, and troubleshooting advice.
• How:
  • Join Lovable’s Lovable’s Discord.
  • Share ideas or feature requests on the Feedback Board.

Don’ts When Using Lovable

1. Don’t Skip Authentication

• Why: Adding authentication later disrupts workflows and introduces errors.

2. Don’t Use Vague Prompts

• Why: Broad instructions without specifics lead to unsatisfactory outcomes.
• Example to Avoid:

  Build a feedback system with everything users need.

3. Don’t Ignore the Revert Function

• Why: Mistakes happen. The Revert function allows you to return to a stable state.
• How: Use Revert in the chat history to undo problematic changes.

4. Don’t Overlook Testing

• Why: Regular testing ensures features function as intended.
• How: Use Lovable’s preview links to test changes frequently.

5. Don’t Neglect Component Size

• Why: Large components can confuse the AI and slow development.
• How: Regularly refactor large files into smaller subcomponents.
