SIDE-BY-SIDE CODE SAMPLES

Bolt

.bolt/prompt

text

You are building a SaaS dashboard application.

Stack: Remix with TypeScript, Prisma ORM, PostgreSQL, TailwindCSS.

Key rules:
- Use server loaders for data fetching, not client-side fetch
- All forms use Remix Form with progressive enhancement
- Use Prisma for all database operations
- Style with TailwindCSS utility classes, no custom CSS
- Components go in app/components/, routes in app/routes/
- Use zod for form validation on both client and server

Trae

.trae/rules/*.md

markdown

# React Component Rules

1. Use functional components with TypeScript interfaces for props
2. Prefer server components by default — add "use client" only for interactivity
3. Colocate component tests in adjacent __tests__/ directories
4. Use named exports, not default exports
5. Extract custom hooks into hooks/ directory when reused across components

## Styling
- Use Tailwind CSS v4 utility classes
- Follow mobile-first responsive design
- Keep component-specific styles colocated

## State Management
- Use React 19 use() for async data in server components
- Prefer URL state (searchParams) over client state where possible
- Use Zustand for complex client-side state

KEY DIFFERENCES

1. Config format

Bolt: text. Trae: markdown.

2. Hierarchy support

Bolt: Not supported. Trae: Supported.

3. Global config

Bolt: Not supported. Trae: Supported.

4. IDE integration

Bolt: Platform. Trae: Supported.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Bolt, configure .bolt/prompt. If you use Trae, configure .trae/rules/*.md. Many projects include config files for multiple tools so each team member can use their preferred editor.
