# SharePoint Expert

## Core Concepts

### SharePoint Architecture

- **Site Collections** - Top-level sites with shared settings
- **Sites & Subsites** - Hierarchical structure
- **Lists & Libraries** - Data storage containers
- **Content Types** - Reusable content definitions
- **Site Columns** - Reusable field definitions
- **Permissions** - Security and access control

### Development Approaches

- **SPFx** - SharePoint Framework (modern)
- **Add-ins** - SharePoint-hosted and provider-hosted apps
- **Web Parts** - Custom UI components
- **Extensions** - Application customizers, field customizers
- **REST API** - RESTful web services
- **CSOM** - Client-Side Object Model

### Content Management

- **Document Management** - Version control, check-in/out
- **Metadata** - Columns and managed metadata
- **Search** - Enterprise search capabilities
- **Workflows** - Business process automation
- **Information Management** - Retention and policies
- **Records Management** - Compliance and governance

## Best Practices

### Site Architecture

- Use hub sites for site association
- Implement flat site structure (avoid deep subsites)
- Use modern sites over classic
- Apply consistent branding and theming
- Use site templates for standardization
- Implement proper governance

### Content Organization

- Use content types for consistency
- Apply metadata for better findability
- Implement managed metadata for taxonomy
- Use document sets for related documents
- Configure version control appropriately
- Set up retention and disposal policies

### Development Standards

- Follow SPFx development guidelines
- Use PnP libraries for common operations
- Implement proper error handling
- Use TypeScript for type safety
- Test in dev/test before production
- Document custom solutions

### Performance Optimization

- Minimize REST API calls
- Use batch operations for multiple requests
- Implement caching strategies
- Optimize views and queries
- Use indexed columns for large lists
- Avoid client-side heavy operations

## Anti-Patterns

### Architecture Issues

- Deep site hierarchy (more than 2-3 levels)
- Over-customization of out-of-box features
- Using classic sites for new development
- Inconsistent information architecture
- No governance or naming conventions
- Mixed modern and classic experiences

### Development Problems

- Using JSOM in new solutions (use REST or PnP)
- Hard-coding site URLs
- No error handling
- Synchronous operations blocking UI
- Direct DOM manipulation
- Missing responsive design

### Content Management Issues

- Using folders instead of metadata
- Not leveraging content types
- Poor metadata strategy
- No retention policies
- Inadequate permissions structure
- Missing backup strategy
