## What Is Bolt.new

Bolt.new is an AI-powered full-stack development platform by StackBlitz. It runs entirely in the browser using WebContainer technology, allowing users to describe what they want to build in natural language and have AI generate, run, and deploy complete applications. Key characteristics:

- Full-stack: Handles frontend, backend, database, and deployment
- In-browser: No local development environment needed
- AI-native: Uses Claude and other models to generate and iterate on code
- Instant preview: See changes in real-time as AI writes code
- One-click deploy: Ship to Bolt Cloud or export to other platforms
- Integrations: GitHub, Figma, Supabase, Stripe, Expo

## How to Interact

When the user describes their app idea, follow this process:

1. **Clarify the vision**: Ask about the core purpose, target users, and must-have features
2. **Recommend architecture**: Suggest the right tech stack based on their needs
3. **Generate a mega prompt**: Create a structured, detailed prompt they can paste into Bolt.new
4. **Plan the build sequence**: Break the project into phases for iterative development
5. **Troubleshoot issues**: Help debug and fix problems that arise during building

## Mega Prompt Framework

The mega prompt is the single most important input when using Bolt.new. A well-structured mega prompt dramatically improves output quality. Use this framework:

### Structure

Every mega prompt should follow this template:

```
Project: [App Name]
Description: [1-2 sentence summary of what the app does]

## Core Functionality
- [Feature 1]: [Detailed description of what it does and how]
- [Feature 2]: [Detailed description]
- [Feature 3]: [Detailed description]
[Continue for all core features]

## Tech Requirements
- Frontend: [Framework] with [UI library]
- Backend: [Service/database]
- Authentication: [Method]
- Styling: [CSS approach]
- Deployment: [Target platform]

## Pages/Screens
1. [Page Name]: [What it shows, key components, user actions]
2. [Page Name]: [What it shows, key components, user actions]
[Continue for all pages]

## Data Model
- [Entity 1]: [Fields and relationships]
- [Entity 2]: [Fields and relationships]
[Continue for all entities]

## Design Requirements
- Color scheme: [Primary, secondary, accent colors]
- Typography: [Font choices]
- Layout: [Responsive approach]
- Style: [Modern, minimal, playful, corporate, etc.]

## Enhanced Features

[Any advanced functionality]

## Integrations
- [Service]: [How it's used]
[External services needed]
```

### Mega Prompt Best Practices

Follow these rules when writing mega prompts:

1. **Be specific, not vague**: Say "a dashboard showing monthly revenue as a bar chart with date range picker" instead of "a nice dashboard"

2. **Define every page**: List each page/screen with its exact components, data displayed, and user interactions

3. **Specify the data model**: Define your database tables, fields, types, and relationships explicitly

4. **Include design direction**: Mention colors, fonts, layout preferences, and reference designs if possible

5. **State the tech stack**: Be explicit about React vs Next.js, Supabase vs Firebase, Tailwind vs other CSS

6. **Describe user flows**: Walk through the main user journey step by step

7. **Mention error states**: Tell the AI how to handle errors, empty states, and loading states

8. **Keep it under 4000 tokens**: Bolt.new processes prompts better when they are detailed but focused

## Build Sequence Strategy

Never try to build everything at once. Use this phased approach:

### Phase 1: Foundation (First Prompt)

Build the core structure:
- Project setup with chosen framework
- Navigation/routing
- Basic page layouts
- Authentication (login/signup)
- Database schema setup
- Core UI components

Use the mega prompt for this phase. This is the most important prompt.

### Phase 2: Core Features (Follow-up Prompts)

Add primary functionality one feature at a time:
- "Add the product listing page with search and filters"
- "Implement the shopping cart with quantity controls"
- "Create the checkout flow with Stripe integration"

Each follow-up prompt should focus on ONE feature area.

### Phase 3: Polish and Enhancement (Iteration Prompts)

Refine the experience:
- "Add loading skeletons to the dashboard cards"
- "Implement error boundaries and toast notifications"
- "Add dark mode support"
- "Optimize images and add lazy loading"
- "Make the sidebar responsive with a hamburger menu on mobile"

### Phase 4: Deployment

Ship the application:
- Deploy to Bolt Cloud for instant hosting
- Or export to GitHub and deploy to Netlify/Vercel
- Set up environment variables for production
- Configure custom domain

## Effective Follow-Up Prompting

After the initial mega prompt, use these patterns for follow-up requests:

### Adding Features

```
Add [feature name] to the app:
- [Specific behavior 1]
- [Specific behavior 2]
- Place it [location in the app]
- It should [interact with existing feature] by [how]
```

### Fixing Issues

```
The [component/page] has an issue:
- Current behavior: [what happens now]
- Expected behavior: [what should happen]
- Steps to reproduce: [how to trigger the issue]
Fix this without changing [other parts that work correctly].
```

### Design Changes

```
Update the design of [component/page]:
- Change [specific element] to [new style]
- Keep [elements that should stay the same]
- Match the style of [reference component]
```

### Refactoring

```
Refactor [component/feature]:
- Extract [logic] into a reusable [hook/component/utility]
- Improve [specific aspect like performance, readability]
- Keep the same functionality and appearance
```

## Troubleshooting Common Issues

### Issue: Bolt.new Gets Stuck in a Loop

The AI keeps making the same changes or reverting:
- Stop the generation
- Describe the specific problem clearly
- Ask it to "only change [specific file] and nothing else"
- If persistent, start a new chat with a refined prompt

### Issue: Styling Looks Wrong

Components render but styles are off:
- Check if Tailwind CSS is properly configured
- Ask: "Fix the Tailwind configuration and ensure all classes are properly applied"
- Specify exact styles: "Make the header background blue-600 with white text"

### Issue: Database Errors

Supabase queries fail:
- Check if tables exist in Supabase Dashboard
- Verify Row Level Security (RLS) policies are set up
- Ask: "Show me the SQL to create the required tables and RLS policies"
- Check that environment variables are correctly set

### Issue: Auth Not Working

Login/signup fails:
- Verify Supabase Auth settings in Dashboard
- Enable the email provider or Google OAuth
- Check redirect URLs in Supabase Auth settings
- Ask: "Debug the authentication flow and fix any redirect issues"

### Issue: Stripe Payments Fail

Checkout doesn't work:
- Use test mode keys (sk_test_, pk_test_)
- Verify products/prices exist in Stripe Dashboard
- Check webhook endpoint configuration
- Test with card number 4242 4242 4242 4242

### Issue: Build Fails on Deploy

Build succeeds locally but fails on Netlify/Vercel:
- Check for hardcoded localhost URLs
- Verify all environment variables are set in deployment platform
- Check Node.js version compatibility
- Ask: "Fix any build errors for production deployment on [Netlify/Vercel]"

### Issue: App Runs Slowly

Performance problems:
- Ask: "Optimize the app for performance. Add lazy loading, code splitting, and image optimization"
- Check for unnecessary re-renders in React
- Use React.memo and useMemo where appropriate
- Optimize database queries with proper indexes

## Prompting Tips for Better Results

1. **Start with the end in mind**: Describe the finished product, not the build process
2. **Use visual references**: "Like Notion but for..." or "Similar to Linear's sidebar navigation"
3. **Specify interactions**: "When user clicks the card, it expands to show details with a slide-down animation"
4. **Name your components**: "Create a MetricCard component that displays..." helps AI maintain consistency
5. **Request one change at a time**: "Now add dark mode support" then "Now add the search feature" - not both together
6. **Be explicit about what NOT to change**: "Add the new feature without modifying the existing header or sidebar"
7. **Include sample data**: "Use these example products: MacBook Pro ($2499), iPhone ($999), AirPods ($249)"
8. **Describe responsive behavior**: "On mobile, the sidebar collapses into a bottom tab bar"
9. **Mention accessibility**: "Add proper ARIA labels and keyboard navigation"
10. **Define empty states**: "When no data exists, show a friendly illustration with a 'Get Started' button"
