# Builders (Deprecated)

**This document is deprecated.** See [`BUILDERS.md`](docs/architecture/website/BUILDERS.md) for the current pattern.

## Summary of changes

The architecture has been updated to use **Builders** instead of **Presenters**:

### Old pattern (deprecated)
- `lib/presenters/` - All transformations
- `lib/view-models/` - ViewModels + some presenters

### New pattern (current)
- `lib/builders/view-models/` - DTO → ViewModel
- `lib/builders/view-data/` - ViewModel → ViewData
- `lib/view-models/` - ViewModels only

### Why the change?

The old pattern had **three anti-patterns**:

1. **Inconsistent naming** - Same concept had 3 names (Presenter, Transformer, ViewModelPresenter)
2. **Inconsistent location** - Presenters lived in both `lib/presenters/` and `lib/view-models/`
3. **Confusing semantics** - "Presenter" implies presenting to client, but some presenters prepared data for server templates

### What changed?

**ViewModel Builders** (DTO → ViewModel):
- Location: `lib/builders/view-models/`
- Naming: `*ViewModelBuilder`
- Example: `AdminViewModelBuilder.build(dto)`

**ViewData Builders** (ViewModel → ViewData):
- Location: `lib/builders/view-data/`
- Naming: `*ViewDataBuilder`
- Example: `LeagueViewDataBuilder.build(viewModel, id)`

This makes the architecture **self-documenting** and **clean**.
