- Improve config label with clearer wording: "Full JSON configuration or use [Config Wizard]"
- Add JSON format button to beautify configuration with 2-space indentation
- Update tests to reflect new default behavior
- Clean up redundant explicit prop passing
This provides a more streamlined experience by enabling all apps out of the box
and making it easier to format JSON configurations.
Complete the v3.7.0 MCP refactoring by updating the form layer to match
the unified architecture already implemented in data/service/API layers.
**Breaking Changes:**
- Remove confusing `appId` parameter from McpFormModal
- Replace with `defaultFormat` (json/toml) and `defaultEnabledApps` (array)
**Form Enhancements:**
- Add app enablement checkboxes (Claude/Codex/Gemini) directly in the form
- Smart defaults: new servers default to Claude enabled, editing preserves state
- Support "draft" mode: servers can be created without enabling any apps
**Architecture Improvements:**
- Eliminate semantic confusion: format selection separate from app targeting
- One-step workflow: configure and enable apps in single form submission
- Consistent with unified backend: `apps: { claude, codex, gemini }`
**Testing:**
- Update test mocks to use `useUpsertMcpServer` hook
- Add test case for creating servers with no apps enabled
- Fix parameter references from `appId` to `defaultFormat`
**i18n:**
- Add `mcp.form.enabledApps` translation (zh/en)
- Add `mcp.form.noAppsWarning` translation (zh/en)
This completes the MCP management refactoring, ensuring all layers
(data, service, API, UI) follow the same unified architecture pattern.
Complete Phase 3 (P0) frontend implementation for unified MCP management:
**New Files:**
- src/hooks/useMcp.ts: React Query hooks for unified MCP operations
- src/components/mcp/UnifiedMcpPanel.tsx: Unified MCP management panel
- src/components/ui/checkbox.tsx: Checkbox component from shadcn/ui
**Features:**
- Unified panel with three-column layout: server info + app checkboxes + actions
- Multi-app control: Claude/Codex/Gemini checkboxes for each server
- Real-time stats: Show enabled server counts per app
- Full CRUD operations: Add, edit, delete, sync all servers
**Integration:**
- Replace old app-specific McpPanel with UnifiedMcpPanel in App.tsx
- Update McpFormModal to support unified mode with apps field
- Add i18n support: mcp.unifiedPanel namespace (zh/en)
**Type Safety:**
- Ensure McpServer.apps field always initialized
- Fix all test files to include apps field
- TypeScript type check passes ✅
**Architecture:**
- Single source of truth: mcp.servers manages all MCP configs
- Per-server app control: apps.claude/codex/gemini boolean flags
- Backward compatible: McpFormModal supports both unified and legacy modes
Next: P1 tasks (import dialogs, sub-components, tests)
This commit addresses parameter naming inconsistencies caused by Tauri v2's
requirement for camelCase parameter names in IPC commands.
Backend changes (Rust):
- Updated all command parameters from snake_case to camelCase
- Commands affected:
* provider.rs: providerId (×4), timeoutSecs
* import_export.rs: filePath (×2), defaultName
* config.rs: defaultPath
- Added #[allow(non_snake_case)] attributes for camelCase parameters
- Removed unused QueryUsageParams struct
Frontend changes (TypeScript):
- Removed redundant snake_case parameters from all invoke() calls
- Updated API files:
* usage.ts: removed debug logs, unified to providerId
* vscode.ts: updated 8 functions (providerId, timeoutSecs, filePath, defaultName)
* settings.ts: updated 4 functions (defaultPath, filePath, defaultName)
- Ensured all parameters now use camelCase exclusively
Test updates:
- Updated MSW handlers to accept both old and new parameter formats during transition
- Added i18n mock compatibility for tests
Root cause:
The issue stemmed from Tauri v2 strictly requiring camelCase for command
parameters, while the codebase was using snake_case. This caused parameters
like 'provider_id' to not be recognized by the backend, resulting in
"missing providerId parameter" errors.
BREAKING CHANGE: All Tauri command invocations now require camelCase parameters.
Any external tools or scripts calling these commands must be updated accordingly.
Fixes: Usage query always failing with "missing providerId" error
Fixes: Custom endpoint management not receiving provider ID
Fixes: Import/export dialogs not respecting default paths
- Add postChangeSync.ts utility with Result pattern for graceful error handling
- Replace try-catch with syncCurrentProvidersLiveSafe in useImportExport
- Add directory-change-triggered sync in useSettings to maintain SSOT
- Introduce partial-success status to distinguish import success from sync failures
- Add test coverage for sync behavior in different scenarios
This refactoring ensures config.json changes are reliably synced to live
files while providing better user feedback for edge cases.
Rename `AppType` to `AppId` across the entire frontend codebase to better
reflect its purpose as an application identifier rather than a type category.
This aligns frontend naming with backend command parameter conventions.
Changes:
- Rename type `AppType` to `AppId` in src/lib/api/types.ts
- Remove `AppType` export from src/lib/api/index.ts
- Update all component props from `appType` to `appId` (43 files)
- Update all variable names from `appType` to `appId`
- Synchronize documentation (CHANGELOG, refactoring plans)
- Update test files and MSW mocks
BREAKING CHANGE: `AppType` type is no longer exported. Use `AppId` instead.
All component props have been renamed from `appType` to `appId`.
Replace the previous dual-parameter approach (app_type/app/appType) with a single required `app: String` parameter across all Tauri commands. This change:
- Introduces unified `parse_app()` helper replacing complex `resolve_app_type()` logic
- Updates all backend commands in config, mcp, and provider modules
- Aligns frontend API calls to use consistent `app` parameter naming
- Simplifies MSW test handlers by removing optional parameter handling
This improves API clarity and reduces parameter ambiguity while maintaining backward compatibility through error handling.
Update test infrastructure to support the dual app type parameter pattern
(app_type enum + app string) introduced in 590be4e:
- Add toast.warning mock for partial-success status handling
- Add syncCurrentProvidersLive mock to test post-import sync behavior
- Update MSW handlers to accept both app_type and app parameters with
fallback resolution (app ?? app_type) across 7 provider endpoints
- Add sync_current_providers_live endpoint mock returning success
This ensures test compatibility during the app_type → app parameter
migration and enables testing of the new partial-success import flow.
Fixed two critical data loss bugs where user-added custom endpoints were discarded:
1. **AddProviderDialog**: Form submission ignored values.meta from ProviderForm and
re-inferred URLs only from presets/config, causing loss of endpoints added via
speed test modal. Now prioritizes form-collected meta and uses fallback inference
only when custom_endpoints is missing.
2. **ProviderForm**: Edit mode always returned initialData.meta, discarding any
changes made in the speed test modal. Now uses mergeProviderMeta to properly
merge customEndpointsMap with existing meta fields.
Changes:
- Extract mergeProviderMeta utility to handle meta field merging logic
- Preserve other meta fields (e.g., usage_script) during endpoint updates
- Unify new/edit code paths to use consistent meta handling
- Add comprehensive unit tests for meta merging scenarios
- Add integration tests for AddProviderDialog submission flow
Impact:
- Third-party and custom providers can now reliably manage multiple endpoints
- Edit operations correctly reflect user modifications
- No data loss for existing meta fields like usage_script
- Add vitest/globals to tsconfig.json types array to provide type
definitions for global test functions (describe, it, expect, vi)
- Fix vi.fn type parameter in useDirectorySettings.test.tsx from
<[], Promise<string>> to <() => Promise<string>>
- Remove unused setMcpConfig import from MSW handlers
- Add type assertions for mock.calls access in McpFormModal tests
to resolve union type inference issues
This ensures pnpm typecheck passes without errors while maintaining
test functionality with vitest globals: true configuration.
