Walkthrough

Adds VITE_PROVIDER_DB_URL to env examples, CI workflows, and Vite TypeScript typings. Introduces a helper to obtain the provider DB URL (trim + fallback) and uses it in provider DB refresh. Changes model config to avoid on-demand ElectronStore reads on memory cache miss.

Changes

Cohort / File(s)	Change summary
Environment example `\.env.example`	Added `VITE_PROVIDER_DB_URL` placeholder pointing to a hosted JSON.
CI workflows env injection `.github/workflows/build.yml`, `.github/workflows/prcheck.yml`	Inject `VITE_PROVIDER_DB_URL` from `secrets.CDN_PROVIDER_DB_URL` into build and PR jobs (added env entries in multiple build steps).
Vite env TypeScript typings `src/main/env.d.ts`, `src/renderer/src/env.d.ts`	Added optional `VITE_PROVIDER_DB_URL?: string`; also added `VITE_APP_LIFECYCLE_HOOK_DELAY?: string` in `src/main/env.d.ts`.
Provider DB loader `src/main/presenter/configPresenter/providerDbLoader.ts`	Added private `getProviderDbUrl()` that trims `VITE_PROVIDER_DB_URL` and falls back to `DEFAULT_PROVIDER_DB_URL`; `refreshIfNeeded` now calls this helper.
Model config cache lookup `src/main/presenter/configPresenter/modelConfig.ts`	Removed on-demand `ElectronStore` reads on cache miss; `getModelConfig` now returns `undefined` if key not present in memory (normalized-key path handled similarly).

Poem

I nibbled through envs with whiskered delight,
A tiny URL carrot now gleams in CI light.
Memory holds fast — no store in a dash,
A trimming helper hums with a tidy little sash.
Thump goes my paw: configs hop and dash 🥕🐇

src/main/presenter/configPresenter/providerDbLoader.ts (2)

149-149: LGTM - Good refactor to use the helper method.

Delegating URL retrieval to the dedicated helper improves maintainability and ensures consistent trimming and fallback logic. The change is clean and follows the single responsibility principle.

Note: This approval assumes the helper method works correctly at runtime (see verification request on lines 136-144).

136-144: import.meta.env usage in main process is correct The project’s vite.config bundles the main process via electron-vite, so import.meta.env references are replaced at build time and behave as intended.

10-10: LGTM!

The addition of VITE_PROVIDER_DB_URL to the example environment configuration is appropriate and follows the project's pattern for VITE_* variables.

.github/workflows/prcheck.yml (1)

50-51: LGTM!

The environment variable injection is correctly configured and aligns with the broader PR objective to source the provider DB URL from environment configuration.

.github/workflows/build.yml (3)

65-65: LGTM!

The Windows build step correctly injects VITE_PROVIDER_DB_URL from secrets, consistent with other VITE_* variables.

119-119: LGTM!

The Linux build step correctly injects VITE_PROVIDER_DB_URL from secrets, consistent with other VITE_* variables.

256-258: Same cache behavior concern applies to normalized key lookup.

This normalized key lookup also only checks the memory cache without store fallback. Ensure this is consistent with the intended caching strategy.

src/renderer/src/env.d.ts (1)

15-15: LGTM!

The type definition for VITE_PROVIDER_DB_URL is correct and consistent with the main process environment typings.

src/main/presenter/configPresenter/providerDbLoader.ts (2)

136-144: LGTM!

The getProviderDbUrl() helper is well-implemented with proper validation:

Type checking for string

Whitespace trimming

Empty string check

Sensible fallback to DEFAULT_PROVIDER_DB_URL

This centralizes URL resolution and aligns with the PR objective.

149-149: LGTM!

Using the helper method ensures consistent URL resolution throughout the refresh logic.

src/main/env.d.ts (1)

9-9: LGTM!

The VITE_PROVIDER_DB_URL type definition correctly supports the PR objective and is consistent with the renderer environment typings.

+      const cachedEntry = this.memoryCache.has(cacheKey)
+        ? (this.memoryCache.get(cacheKey) as IModelConfig | undefined)
+        : undefined


🛠️ Refactor suggestion | 🟠 Major

🧩 Analysis chain

Verify the cache behavior change is intentional.

The cache lookup logic now only checks the in-memory cache without falling back to the store on a miss. While initializeCache() is called at the start of getModelConfig(), this behavior change could cause issues if:

The memory cache is explicitly cleared via clearMemoryCache() or clearAllConfigs() without subsequent reinitialization

There are concurrent modifications to the store outside this class

Note that hasUserConfig() (line 439) still reads from the store as a fallback, which is inconsistent with this approach.

Run the following script to verify where the memory cache might be cleared:

🏁 Script executed:

#!/bin/bash # Search for clearMemoryCache and clearAllConfigs calls rg -nP '\bclearMemoryCache\s*\(|\bclearAllConfigs\s*\(' --type=ts -C3

Length of output: 1690

🏁 Script executed:

#!/bin/bash rg -nP --type=ts 'getModelConfig\(' -C15 src/main/presenter/configPresenter/modelConfig.ts

Length of output: 1192

Restore store fallback or sync cache on writes

getModelConfig now returns undefined on a cache miss without falling back to modelConfigStore. Because initializeCache() only runs once, any configs added or updated afterward (e.g. via importConfigs) won’t be visible until the cache is reset. Either reintroduce a store lookup for cache misses or update memoryCache whenever the store changes.

🤖 Prompt for AI Agents

In src/main/presenter/configPresenter/modelConfig.ts around lines 246–248, getModelConfig currently returns undefined on a memoryCache miss which breaks visibility for configs added/updated after initializeCache; either reintroduce a fallback lookup to modelConfigStore or ensure the store-write paths update memoryCache. Fix by: on cache miss call the modelConfigStore to load the entry, set it into memoryCache before returning, and/or update importConfigs/any config write functions to write-through to memoryCache (i.e., after storing to modelConfigStore, update memoryCache.set(cacheKey, newConfig)). Ensure both synchronous return semantics and error handling for store access.

src/main/presenter/configPresenter/providerDbLoader.ts (1)
150-150: Replace console.log with structured logging.

The console.log statement doesn't follow the project's structured logging guidelines, which require log levels (ERROR, WARN, INFO, DEBUG), timestamps, and structured format.

As per coding guidelines, consider using a proper logging utility or at minimum include a log level prefix:
-    console.log('load provider url', url)
+    console.info('[INFO] Loading provider database from URL:', url)
Or better yet, use a structured logging library if available in the project.

Note: Ensure the URL doesn't contain sensitive information before logging. Based on learnings and coding guidelines.

136-144: Ensure environment variable resolution matches runtime requirements
import.meta.env.VITE_PROVIDER_DB_URL is baked in at build time and cannot be overridden at runtime, while scripts/fetch-provider-db.mjs uses process.env.PROVIDER_DB_URL. Confirm this discrepancy is intentional or switch to using process.env for provider-DB URL if you need runtime configurability.
