From 7c3738db361baa8f411db9e11d9d9a649d5e3594 Mon Sep 17 00:00:00 2001 From: LocalMind Dev Date: Mon, 5 Jan 2026 02:25:47 +0530 Subject: [PATCH 1/2] feat: Complete Ollama AI integration with health checks and documentation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #23 ### Changes Made: #### 1. Environment Configuration - ✅ Added OLLAMA_HOST to env schema (default: http://localhost:11434) - ✅ Added OLLAMA_DEFAULT_MODEL to env schema (default: llama3) - ✅ Updated .env.example with Ollama configuration - ✅ Removed hardcoded URLs throughout codebase #### 2. Enhanced Ollama Controller - ✅ Added checkOllamaStatus() - Health check endpoint - ✅ Added listModels() - List all installed models - ✅ Added testModel() - Test specific model with sample prompt - ✅ Improved error handling with specific messages - ✅ Added connection status detection (ECONNREFUSED) #### 3. Updated Service Layer - ✅ Replaced hardcoded 'http://localhost:11434' with env.OLLAMA_HOST - ✅ Applied to both getVector() and generateText() methods - ✅ Consistent configuration across all Ollama operations #### 4. Enhanced Utils - ✅ Updated isModelAvailable() to use env.OLLAMA_HOST - ✅ Updated listAvailableModels() to use env.OLLAMA_HOST - ✅ Better error messages for offline server #### 5. New API Endpoints - ✅ GET /api/v1/ollama/status - Check server status - ✅ GET /api/v1/ollama/models - List available models - ✅ GET /api/v1/ollama/test/:model - Test model with sample prompt - ✅ POST /api/v1/chat-with-ollama - Existing chat endpoint (unchanged) #### 6. Comprehensive Documentation - ✅ Created docs/OLLAMA_SETUP.md (200+ lines) - ✅ Installation guide for macOS/Linux/Windows - ✅ Model setup and recommendations - ✅ API endpoint documentation with curl examples - ✅ Troubleshooting section with common issues - ✅ Performance tips and best practices - ✅ Docker setup instructions - ✅ Added link in main README ### Files Changed: - LocalMind-Backend/src/validator/env.ts - LocalMind-Backend/src/api/v1/Ai-model/Ollama/Ollama.controller.ts - LocalMind-Backend/src/api/v1/Ai-model/Ollama/Ollama.service.ts - LocalMind-Backend/src/api/v1/Ai-model/Ollama/Ollama.utils.ts - LocalMind-Backend/src/api/v1/Ai-model/Ollama/Ollama.routes.ts - LocalMind-Backend/.env.example - README.md - docs/OLLAMA_SETUP.md (NEW) ### Testing: Test with curl: ```bash # Check status curl http://localhost:5000/api/v1/ollama/status # List models curl http://localhost:5000/api/v1/ollama/models # Test model curl http://localhost:5000/api/v1/ollama/test/llama3 # Chat curl -X POST http://localhost:5000/api/v1/chat-with-ollama \ -H 'Content-Type: application/json' \ -d '{"prompt": "Hello", "model": "llama3"}' ``` ### Impact: - No breaking changes (backward compatible) - Existing Ollama endpoints work unchanged - New endpoints provide better observability - Production-ready with env-based config - Comprehensive docs for new users ### Issue #23 Requirements: - [x] Installation guide (macOS/Linux/Windows) - [x] Download base models - [x] Project integration with reusable service - [x] Environment config (.env) - [x] Test implementation (3 new endpoints) - [x] Documentation in README and dedicated guide - [x] Troubleshooting section --- LocalMind-Backend/.env.example | 4 + .../v1/Ai-model/Ollama/Ollama.controller.ts | 72 ++++ .../api/v1/Ai-model/Ollama/Ollama.routes.ts | 10 + .../api/v1/Ai-model/Ollama/Ollama.service.ts | 5 +- .../api/v1/Ai-model/Ollama/Ollama.utils.ts | 5 +- LocalMind-Backend/src/validator/env.ts | 3 + README.md | 2 +- docs/OLLAMA_SETUP.md | 363 ++++++++++++++++++ 8 files changed, 459 insertions(+), 5 deletions(-) create mode 100644 docs/OLLAMA_SETUP.md diff --git a/LocalMind-Backend/.env.example b/LocalMind-Backend/.env.example index 31364a5..bcaf04b 100644 --- a/LocalMind-Backend/.env.example +++ b/LocalMind-Backend/.env.example @@ -45,3 +45,7 @@ BACKEND_URL=http://localhost:5000 OPENAI_API_KEY=your_openai_api_key_here GOOGLE_API_KEY=your_google_api_key_here GROQ_API_KEY=your_groq_api_key_here + +# Ollama Configuration (Local LLM) +OLLAMA_HOST=http://localhost:11434 +OLLAMA_DEFAULT_MODEL=llama3 diff --git a/LocalMind-Backend/src/api/v1/Ai-model/Ollama/Ollama.controller.ts b/LocalMind-Backend/src/api/v1/Ai-model/Ollama/Ollama.controller.ts index abcfc8f..78a3960 100644 --- a/LocalMind-Backend/src/api/v1/Ai-model/Ollama/Ollama.controller.ts +++ b/LocalMind-Backend/src/api/v1/Ai-model/Ollama/Ollama.controller.ts @@ -2,6 +2,8 @@ import { Request, Response } from 'express' import { SendResponse } from '../../../../utils/SendResponse.utils' import OllamaService from './Ollama.service' import OllamaUtils from './Ollama.utils' +import axios from 'axios' +import { env } from '../../../../constant/env.constant' class OllamaController { async ChartWithOllama(req: Request, res: Response) { @@ -20,6 +22,76 @@ class OllamaController { SendResponse.error(res, 'Failed to generate AI response', 500, err) } } + + async checkOllamaStatus(req: Request, res: Response) { + try { + const response = await axios.get(`${env.OLLAMA_HOST}/api/tags`) + + const models = response.data.models || [] + + SendResponse.success( + res, + 'Ollama is running and accessible', + { + status: 'online', + host: env.OLLAMA_HOST, + models: models.map((m: any) => ({ + name: m.name, + size: m.size, + modified: m.modified_at, + })), + totalModels: models.length, + }, + 200 + ) + } catch (error: any) { + if (error.code === 'ECONNREFUSED' || error.code === 'ECONNRESET') { + SendResponse.error( + res, + 'Ollama server is not running.
