# Plan: Document Favorites Feature Session
|
|
|
|
## Context
|
|
This session added the Favorites data-access and service layer to the Spring Boot app.
|
|
The goal is to capture everything done — files created, design decisions, and API surface —
|
|
in a new `docs/favorites-feature.md`, consistent with the style of existing docs files
|
|
(`docs/setup-summary.md`, `docs/integration-testing.md`).
|
|
|
|
---
|
|
|
|
## File to Create
|
|
|
|
### `docs/favorites-feature.md`
|
|
|
|
Content to include:
|
|
|
|
1. **What was built** — one-sentence summary
|
|
2. **Files created** — table of the two new files with their package paths
|
|
3. **FavoriteRepository** — method table (name, return type, reason)
|
|
- Note on `@Transactional` on `deleteByUserIdAndItemId`
|
|
4. **FavoriteService** — method table (name, behaviour / error thrown)
|
|
- Note on class-level `@Transactional` + `readOnly = true` overrides on reads
|
|
5. **Design decisions** — duplicate guard in `addFavorite`, existence check in `removeFavorite`
|
|
6. **Verification** — `mvn clean compile`
|
|

## Verification
