# Remove legacy API layer (APIClient, core.ts, resources/)
## Summary
This PR consolidates the API layer by removing unused legacy code. The
codebase had two API patterns:
1. **Adapters layer** (`src/lib/api/adapters/`) - The newer, canonical
HTTP layer with retry logic, caching, and proper error handling
2. **Legacy layer** (`src/lib/api/client.ts`, `core.ts`, `resources/`) -
An older pattern using SvelteKit proxy endpoints that was no longer
imported anywhere
The legacy layer was confirmed unused via grep analysis. The only
exception was `transformResponse` and `transformRequest` functions in
`client.ts` which were still used by `BaseAdapter` and
`schemas/party.ts` - these have been moved to `schemas/transforms.ts`.
**Files deleted:**
- `src/lib/api/client.ts` (732 lines - APIClient class was dead code)
- `src/lib/api/core.ts` (helper functions, unused)
- `src/lib/api/index.ts` (empty file)
- `src/lib/api/resources/` directory (search.ts, weapons.ts,
characters.ts, summons.ts - all unused)
**Files modified:**
- `src/lib/api/schemas/transforms.ts` - Added `transformResponse`,
`transformRequest`, and their helper functions
- `src/lib/api/adapters/base.adapter.ts` - Updated import path
- `src/lib/api/schemas/party.ts` - Updated import path
## Review & Testing Checklist for Human
- [ ] **Verify transform functions work correctly** - The
`transformResponse` and `transformRequest` functions handle critical
data transformation (snake_case ↔ camelCase, object ↔ entity field
renaming). Test that party data loads correctly with proper field names.
- [ ] **Test party CRUD operations** - Create, update, and delete a
party to verify the adapters layer still works end-to-end
- [ ] **Test grid operations** - Add/remove weapons, characters, and
summons to verify the entity field renaming still works correctly
- [ ] **Check for any runtime errors** - The local type checking
couldn't run due to missing dev dependencies, so CI is the first line of
defense
**Recommended test plan:**
1. Load an existing party page and verify all data displays correctly
2. Create a new party and add weapons/characters/summons
3. Edit an existing party (update name, add/remove items)
4. Verify search functionality works for weapons/characters/summons
### Notes
- Local lint/typecheck commands failed due to missing dependencies
(prettier-plugin-svelte, eslint-config-prettier) - relying on CI for
type verification
- The services layer (`src/lib/services/`) was intentionally kept as
it's a business logic layer that wraps the adapters
