# File Structure Guidelines
|
||||
|
||||
## Core File Structure Principles
|
||||
Twenty follows a modular and organized file structure that promotes maintainability and scalability. This document outlines our file organization conventions and best practices.
|
||||
|
||||
## Component Organization
|
||||
|
||||
### One Component Per File
|
||||
- Each component should have its own file
|
||||
- File name should match component name
|
||||
```typescript
|
||||
// ✅ Correct
|
||||
// UserProfile.tsx
|
||||
export const UserProfile = () => {
|
||||
return <div>...</div>;
|
||||
};
|
||||
|
||||
// ❌ Incorrect
|
||||
// users.tsx
|
||||
export const UserProfile = () => {
|
||||
return <div>...</div>;
|
||||
};
|
||||
|
||||
export const UserList = () => {
|
||||
return <div>...</div>;
|
||||
};
|
||||
```
|
||||
|
||||
## Directory Structure
|
||||
|
||||
### Feature Modules
|
||||
- Place features in `modules/` directory
|
||||
- Group related components and logic
|
||||
```
|
||||
modules/
|
||||
├── users/
|
||||
│ ├── components/
|
||||
│ │ ├── UserList.tsx
|
||||
│ │ ├── UserCard.tsx
|
||||
│ │ └── UserProfile.tsx
|
||||
│ ├── hooks/
|
||||
│ │ └── useUser.ts
|
||||
│ ├── states/
|
||||
│ │ └── userStates.ts
|
||||
│ └── types/
|
||||
│ └── user.ts
|
||||
├── workspace/
|
||||
│ ├── components/
|
||||
│ ├── hooks/
|
||||
│ └── states/
|
||||
└── settings/
|
||||
├── components/
|
||||
├── hooks/
|
||||
└── states/
|
||||
```
|
||||
|
||||
### Hooks Organization
|
||||
- Place hooks in `hooks/` directory
|
||||
- Group by feature or global usage
|
||||
```
|
||||
hooks/
|
||||
├── useClickOutside.ts
|
||||
├── useDebounce.ts
|
||||
└── features/
|
||||
├── users/
|
||||
│ ├── useUserActions.ts
|
||||
│ └── useUserData.ts
|
||||
└── workspace/
|
||||
└── useWorkspaceSettings.ts
|
||||
```
|
||||
|
||||
### State Management
|
||||
- Place state definitions in `states/` directory
|
||||
- Organize by feature
|
||||
```
|
||||
states/
|
||||
├── global/
|
||||
│ ├── theme.ts
|
||||
│ └── navigation.ts
|
||||
├── users/
|
||||
│ ├── atoms.ts
|
||||
│ └── selectors.ts
|
||||
└── workspace/
|
||||
├── atoms.ts
|
||||
└── selectors.ts
|
||||
```
|
||||
|
||||
### Types Organization
|
||||
- Place types in `types/` directory
|
||||
- Group by domain or feature
|
||||
```
|
||||
types/
|
||||
├── common.ts
|
||||
├── api.ts
|
||||
└── features/
|
||||
├── user.ts
|
||||
├── workspace.ts
|
||||
└── settings.ts
|
||||
```
|
||||
|
||||
## Naming Conventions
|
||||
|
||||
### Component Files
|
||||
- Use PascalCase for component files
|
||||
- Use descriptive, feature-specific names
|
||||
```
|
||||
components/
|
||||
├── UserProfile.tsx
|
||||
├── UserProfileHeader.tsx
|
||||
└── UserProfileContent.tsx
|
||||
```
|
||||
|
||||
### Non-Component Files
|
||||
- Use camelCase for non-component files
|
||||
- Use clear, descriptive names
|
||||
```
|
||||
hooks/
|
||||
├── useClickOutside.ts
|
||||
└── useDebounce.ts
|
||||
|
||||
utils/
|
||||
├── dateFormatter.ts
|
||||
└── stringUtils.ts
|
||||
```
|
||||
|
||||
## Module Structure
|
||||
|
||||
### Feature Module Organization
|
||||
- Consistent structure across features
|
||||
- Clear separation of concerns
|
||||
```
|
||||
modules/users/
|
||||
├── components/
|
||||
│ ├── UserList/
|
||||
│ │ ├── UserList.tsx
|
||||
│ │ ├── UserListItem.tsx
|
||||
│ │ └── UserListHeader.tsx
|
||||
│ └── UserProfile/
|
||||
│ ├── UserProfile.tsx
|
||||
│ └── UserProfileHeader.tsx
|
||||
├── hooks/
|
||||
│ ├── useUserList.ts
|
||||
│ └── useUserProfile.ts
|
||||
├── states/
|
||||
│ ├── atoms.ts
|
||||
│ └── selectors.ts
|
||||
├── types/
|
||||
│ └── user.ts
|
||||
└── utils/
|
||||
└── userFormatter.ts
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Import Organization
|
||||
- Group imports by type
|
||||
- Maintain consistent order
|
||||
```typescript
|
||||
// External dependencies
|
||||
import { useState } from 'react';
|
||||
import { styled } from '@emotion/styled';
|
||||
|
||||
// Internal modules
|
||||
import { useUser } from '~/modules/users/hooks';
|
||||
import { userState } from '~/modules/users/states';
|
||||
|
||||
// Local imports
|
||||
import { UserAvatar } from './UserAvatar';
|
||||
import { type UserProfileProps } from './types';
|
||||
```
|
||||
|
||||
### Path Aliases
|
||||
- Use path aliases for better imports
|
||||
- Avoid deep relative paths
|
||||
```typescript
|
||||
// ✅ Correct
|
||||
import { Button } from '~/components/Button';
|
||||
import { useUser } from '~/modules/users/hooks';
|
||||
|
||||
// ❌ Incorrect
|
||||
import { Button } from '../../../components/Button';
|
||||
import { useUser } from '../../../modules/users/hooks';
|
||||
```
|
||||
|
||||
### Component Co-location
|
||||
- Keep related files close together
|
||||
- Use index files for public APIs
|
||||
```
|
||||
components/UserProfile/
|
||||
├── UserProfile.tsx
|
||||
├── UserProfileHeader.tsx
|
||||
├── UserProfileContent.tsx
|
||||
├── styles.ts
|
||||
├── types.ts
|
||||
└── index.ts
|
||||
```
|
||||
|
||||
### Test File Location
|
||||
- Place test files next to implementation
|
||||
- Use `.test.ts` or `.spec.ts` extension
|
||||
```
|
||||
components/
|
||||
├── UserProfile.tsx
|
||||
├── UserProfile.test.tsx
|
||||
├── UserProfile.stories.tsx
|
||||
└── types.ts
|
||||
```
