Add Ollama, LM Studio providers and Tauri desktop app by kpulik · Pull Request #16 · mskayyali/nodepad

kpulik · 2026-04-08T21:09:09Z

Summary

Local AI providers: Adds Ollama and LM Studio as providers, no API key required, models are auto-detected from the running server and shown in a dropdown
Tauri desktop app: Adds a Tauri v2 scaffold so nodepad can run as a native desktop app (npm run tauri:dev / npm run tauri:build), with no CORS restrictions for local providers
CORS proxy routes: Two new API routes (/api/local-models, /api/local-chat) proxy requests to local servers so everything works in the browser without extra configuration

Changed files

File	What
`lib/ai-settings.ts`	New `ollama`/`lmstudio` provider types, dynamic model fetching via `fetchLocalModels()`, `isLocalProvider()` helper, skip auth headers for local providers
`components/project-sidebar.tsx`	Auto-fetch model dropdown for local providers, loading/empty states, refresh button, server URL field, hide API key for local providers
`lib/ai-enrich.ts`	Route local provider chat completions through `/api/local-chat` proxy
`lib/ai-ghost.ts`	Same proxy routing for ghost/synthesis generation
`app/api/local-models/route.ts`	New - proxies model list requests to Ollama/LM Studio (CORS bypass)
`app/api/local-chat/route.ts`	New - proxies chat completion requests to local servers (CORS bypass)
`next.config.mjs`	CSP updated for localhost, conditional `output: "export"` for Tauri builds
`src-tauri/`	New - Tauri v2 project scaffold (Rust backend, config, icons)
`package.json`	Added `@tauri-apps/cli`, `@tauri-apps/api`, `tauri:dev`/`tauri:build` scripts
`README.md`	Setup instructions for browser, desktop app, and local providers

How to use

Browser (unchanged): npm run dev → localhost:3000

Desktop app: npm run tauri:dev (dev) or npm run tauri:build (distributable)

Local providers: Settings → select Ollama or LM Studio → models appear automatically

Test plan

Verify existing cloud providers (OpenRouter, OpenAI, Z.ai) still work unchanged
Select Ollama provider with Ollama running - models should auto-populate in dropdown
Select LM Studio provider with LM Studio server running - models should auto-populate
Add a note with a local provider selected - enrichment should complete
Verify ghost/synthesis works with local providers
npm run tauri:dev opens a native window with the app working
npm run tauri:build produces a distributable binary

- Add Ollama and LM Studio as local AI providers (no API key needed) - Auto-detect installed models via dropdown (fetched from local server) - Proxy local requests through Next.js API routes to bypass CORS - Add Tauri v2 scaffold for native desktop builds (.dmg/.msi/.AppImage) - Conditional static export for Tauri builds (browser mode unchanged) - Update README with setup instructions for browser, desktop, and local providers Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Pull request overview

Adds first-class support for local AI providers (Ollama, LM Studio) and introduces a Tauri v2 desktop scaffold so nodepad can run as a native app, alongside new proxy API routes intended to work around browser CORS limitations.

Changes:

Added ollama / lmstudio provider types with dynamic local model discovery and local-provider header behavior.
Updated settings UI to support local providers (server URL, refreshable model dropdown, hide API key).
Added Tauri v2 scaffold + conditional Next static export + CSP updates, plus new /api/local-models and /api/local-chat proxy routes.

lib/ai-settings.ts:307

loadAIConfig() now allows local providers without an API key, but it can still return a config with an empty modelId (e.g., if the user saves immediately after switching to a local provider before model fetch completes, or leaves it blank). Downstream calls send model: "", which many OpenAI-compatible servers reject. Consider returning null (or a more explicit error) when modelId is falsy, or enforcing a non-empty modelId at save time for local providers.

export function loadAIConfig(): AIConfig | null {
  const s = loadSettings()
  // Local providers don't need an API key
  if (!s.apiKey && !isLocalProvider(s.provider)) return null
  const models = getModelsForProvider(s.provider)
  const model = models.find(m => m.id === s.modelId)
  const modelId = model?.id ?? models[0]?.id ?? s.modelId ?? DEFAULT_MODEL_ID
  const supportsGrounding =
    (s.provider === "openrouter" || s.provider === "openai") &&
    s.webGrounding &&
    (model?.supportsGrounding ?? false)
  return { apiKey: s.apiKey, modelId, supportsGrounding, provider: s.provider, customBaseUrl: s.customBaseUrl }

lib/ai-settings.ts:307

For local providers, getModelsForProvider() returns an empty array. If the user saves settings with an empty/unknown modelId (e.g. just switched to Ollama/LM Studio and fetch hasn’t populated yet), loadAIConfig() falls back to DEFAULT_MODEL_ID (openai/gpt-4o). That value will then be sent to the local server and will reliably fail. Consider special-casing local providers so modelId never falls back to a cloud default (e.g. return null / throw a clear error when s.modelId is empty, or keep modelId as-is for locals and let the UI enforce selection).

export function loadAIConfig(): AIConfig | null {
  const s = loadSettings()
  // Local providers don't need an API key
  if (!s.apiKey && !isLocalProvider(s.provider)) return null
  const models = getModelsForProvider(s.provider)
  const model = models.find(m => m.id === s.modelId)
  const modelId = model?.id ?? models[0]?.id ?? s.modelId ?? DEFAULT_MODEL_ID
  const supportsGrounding =
    (s.provider === "openrouter" || s.provider === "openai") &&
    s.webGrounding &&
    (model?.supportsGrounding ?? false)
  return { apiKey: s.apiKey, modelId, supportsGrounding, provider: s.provider, customBaseUrl: s.customBaseUrl }

Ready for final review/merge.

Addressed all Copilot review comments.
Copilot now reports no new comments.
Branch is up to date with base and merges cleanly.
Local checks completed: production build and production start succeed; browser endpoint returns HTTP 200.
Note: lint script currently requires eslint to be added/configured (non-blocking for this PR).

- Add getSafeContentTypeConfig helper to lib/content-types.ts - Update TileCard, GraphArea, and other UI components with robust fallbacks - Add proactive contentType validation to AI enrichment parser - Document crash fix in BACKLOG.md as issue mskayyali#16
