Ollama TypeScript

Picture this: You're building the next breakthrough AI application, but your JavaScript code crashes at runtime because a model response came back undefined. Sound familiar? Welcome to the wild west of AI development without type safety.

Building reliable AI applications requires more than just connecting to models—it demands robust type safety, proper error handling, and maintainable code architecture. TypeScript integration with Ollama transforms chaotic AI development into a structured, predictable process that catches errors before they reach production.

This comprehensive guide demonstrates how to build production-ready TypeScript applications using Ollama's local AI models. You'll learn type definitions, error handling patterns, and architectural best practices that ensure your AI applications run smoothly in production environments.

Understanding TypeScript and Ollama Integration Benefits

Why TypeScript Matters for AI Development

TypeScript provides compile-time type checking that prevents common runtime errors in AI applications. Traditional JavaScript AI development often fails due to:

  • Undefined model responses breaking application flow
  • Incorrect parameter types causing API failures
  • Missing error handling for network timeouts
  • Inconsistent data structures across different models

TypeScript eliminates these issues by enforcing strict typing throughout your application lifecycle.

Ollama's Local AI Advantage

Ollama runs AI models locally on your machine, providing:

  • Privacy: No data leaves your environment
  • Speed: Reduced latency compared to cloud APIs
  • Cost: No per-request charges
  • Reliability: Works offline without internet dependency

Combining TypeScript's type safety with Ollama's local execution creates robust AI applications that developers can trust.

Setting Up Your TypeScript Ollama Environment

Installation and Initial Configuration

First, install the necessary dependencies for your TypeScript Ollama project:

# Create new TypeScript project
mkdir typescript-ollama-app
cd typescript-ollama-app
npm init -y

# Install TypeScript and Ollama dependencies
npm install ollama
npm install -D typescript @types/node tsx nodemon

# Initialize TypeScript configuration
npx tsc --init

Configure your tsconfig.json for optimal development experience:

{
  "compilerOptions": {
    "target": "ES2022",
    "module": "commonjs",
    "lib": ["ES2022"],
    "outDir": "./dist",
    "rootDir": "./src",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "resolveJsonModule": true,
    "declaration": true,
    "declarationMap": true,
    "sourceMap": true
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules", "dist"]
}

Creating Type-Safe Ollama Client

Build a strongly-typed Ollama client that provides type safety across your entire application:

// src/ollama-client.ts
import { Ollama } from 'ollama';

// Define response interfaces for type safety
export interface ChatResponse {
  model: string;
  created_at: string;
  message: {
    role: 'assistant' | 'user' | 'system';
    content: string;
  };
  done: boolean;
  total_duration?: number;
  load_duration?: number;
  prompt_eval_count?: number;
  prompt_eval_duration?: number;
  eval_count?: number;
  eval_duration?: number;
}

export interface ChatRequest {
  model: string;
  messages: Array<{
    role: 'user' | 'assistant' | 'system';
    content: string;
  }>;
  stream?: boolean;
  options?: {
    temperature?: number;
    top_p?: number;
    top_k?: number;
    repeat_penalty?: number;
    seed?: number;
    num_ctx?: number;
  };
}

export interface ModelInfo {
  name: string;
  modified_at: string;
  size: number;
  digest: string;
  details: {
    format: string;
    family: string;
    families: string[];
    parameter_size: string;
    quantization_level: string;
  };
}

export class TypedOllamaClient {
  private client: Ollama;
  
  constructor(host: string = 'http://localhost:11434') {
    this.client = new Ollama({ host });
  }

  async chat(request: ChatRequest): Promise<ChatResponse> {
    try {
      const response = await this.client.chat(request);
      return response as ChatResponse;
    } catch (error) {
      throw new Error(`Chat request failed: ${error instanceof Error ? error.message : 'Unknown error'}`);
    }
  }

  async listModels(): Promise<ModelInfo[]> {
    try {
      const response = await this.client.list();
      return response.models as ModelInfo[];
    } catch (error) {
      throw new Error(`Failed to list models: ${error instanceof Error ? error.message : 'Unknown error'}`);
    }
  }

  async pullModel(modelName: string): Promise<void> {
    try {
      await this.client.pull({ model: modelName });
    } catch (error) {
      throw new Error(`Failed to pull model ${modelName}: ${error instanceof Error ? error.message : 'Unknown error'}`);
    }
  }

  async generateResponse(
    model: string, 
    prompt: string, 
    options?: ChatRequest['options']
  ): Promise<string> {
    const request: ChatRequest = {
      model,
      messages: [{ role: 'user', content: prompt }],
      options
    };

    const response = await this.chat(request);
    return response.message.content;
  }
}

Building Type-Safe AI Applications

Creating a Conversational AI Service

Develop a service class that handles conversations with proper type safety and error handling:

// src/conversation-service.ts
import { TypedOllamaClient, ChatRequest } from './ollama-client';

export interface ConversationMessage {
  id: string;
  role: 'user' | 'assistant' | 'system';
  content: string;
  timestamp: Date;
  metadata?: {
    model?: string;
    duration?: number;
    tokens?: number;
  };
}

export interface ConversationHistory {
  id: string;
  messages: ConversationMessage[];
  created_at: Date;
  updated_at: Date;
  model: string;
}

export class ConversationService {
  private client: TypedOllamaClient;
  private conversations: Map<string, ConversationHistory> = new Map();

  constructor(client: TypedOllamaClient) {
    this.client = client;
  }

  createConversation(model: string, systemPrompt?: string): string {
    const conversationId = this.generateId();
    const conversation: ConversationHistory = {
      id: conversationId,
      messages: [],
      created_at: new Date(),
      updated_at: new Date(),
      model
    };

    if (systemPrompt) {
      conversation.messages.push({
        id: this.generateId(),
        role: 'system',
        content: systemPrompt,
        timestamp: new Date()
      });
    }

    this.conversations.set(conversationId, conversation);
    return conversationId;
  }

  async sendMessage(
    conversationId: string, 
    message: string, 
    options?: ChatRequest['options']
  ): Promise<ConversationMessage> {
    const conversation = this.conversations.get(conversationId);
    if (!conversation) {
      throw new Error(`Conversation ${conversationId} not found`);
    }

    // Add user message to conversation
    const userMessage: ConversationMessage = {
      id: this.generateId(),
      role: 'user',
      content: message,
      timestamp: new Date()
    };
    conversation.messages.push(userMessage);

    // Prepare request with conversation history
    const request: ChatRequest = {
      model: conversation.model,
      messages: conversation.messages.map(msg => ({
        role: msg.role,
        content: msg.content
      })),
      options
    };

    try {
      const startTime = Date.now();
      const response = await this.client.chat(request);
      const duration = Date.now() - startTime;

      // Add assistant response to conversation
      const assistantMessage: ConversationMessage = {
        id: this.generateId(),
        role: 'assistant',
        content: response.message.content,
        timestamp: new Date(),
        metadata: {
          model: response.model,
          duration,
          tokens: response.eval_count
        }
      };

      conversation.messages.push(assistantMessage);
      conversation.updated_at = new Date();

      return assistantMessage;
    } catch (error) {
      throw new Error(`Failed to send message: ${error instanceof Error ? error.message : 'Unknown error'}`);
    }
  }

  getConversation(conversationId: string): ConversationHistory | undefined {
    return this.conversations.get(conversationId);
  }

  getConversationHistory(conversationId: string): ConversationMessage[] {
    const conversation = this.conversations.get(conversationId);
    return conversation ? [...conversation.messages] : [];
  }

  private generateId(): string {
    return Math.random().toString(36).substr(2, 9);
  }
}

Implementing Error Handling and Validation

Create robust error handling that provides meaningful feedback:

// src/error-handler.ts
export enum OllamaErrorType {
  CONNECTION_ERROR = 'CONNECTION_ERROR',
  MODEL_NOT_FOUND = 'MODEL_NOT_FOUND',
  INVALID_REQUEST = 'INVALID_REQUEST',
  TIMEOUT_ERROR = 'TIMEOUT_ERROR',
  RATE_LIMIT_ERROR = 'RATE_LIMIT_ERROR',
  UNKNOWN_ERROR = 'UNKNOWN_ERROR'
}

export class OllamaError extends Error {
  constructor(
    public type: OllamaErrorType,
    message: string,
    public originalError?: Error
  ) {
    super(message);
    this.name = 'OllamaError';
  }
}

export class ErrorHandler {
  static handleOllamaError(error: unknown): OllamaError {
    if (error instanceof OllamaError) {
      return error;
    }

    if (error instanceof Error) {
      // Parse common error patterns
      if (error.message.includes('ECONNREFUSED')) {
        return new OllamaError(
          OllamaErrorType.CONNECTION_ERROR,
          'Cannot connect to Ollama server. Ensure Ollama is running.',
          error
        );
      }

      if (error.message.includes('model not found')) {
        return new OllamaError(
          OllamaErrorType.MODEL_NOT_FOUND,
          'The requested model is not available. Pull the model first.',
          error
        );
      }

      if (error.message.includes('timeout')) {
        return new OllamaError(
          OllamaErrorType.TIMEOUT_ERROR,
          'Request timed out. The model may be processing a complex request.',
          error
        );
      }
    }

    return new OllamaError(
      OllamaErrorType.UNKNOWN_ERROR,
      'An unexpected error occurred',
      error instanceof Error ? error : new Error(String(error))
    );
  }

  static async withRetry<T>(
    operation: () => Promise<T>,
    maxRetries: number = 3,
    delay: number = 1000
  ): Promise<T> {
    let lastError: Error;

    for (let attempt = 1; attempt <= maxRetries; attempt++) {
      try {
        return await operation();
      } catch (error) {
        lastError = error instanceof Error ? error : new Error(String(error));
        
        if (attempt === maxRetries) {
          throw ErrorHandler.handleOllamaError(lastError);
        }

        // Wait before retrying
        await new Promise(resolve => setTimeout(resolve, delay * attempt));
      }
    }

    throw ErrorHandler.handleOllamaError(lastError!);
  }
}

Advanced TypeScript Patterns for AI Applications

Creating Generic Model Interfaces

Design flexible interfaces that work with different AI models:

// src/model-interfaces.ts
export interface BaseModelConfig {
  model: string;
  temperature?: number;
  maxTokens?: number;
  topP?: number;
  topK?: number;
  repeatPenalty?: number;
}

export interface ModelCapabilities {
  supportsChat: boolean;
  supportsCompletion: boolean;
  supportsEmbedding: boolean;
  contextWindow: number;
  languages: string[];
}

export interface ModelMetrics {
  requestCount: number;
  totalDuration: number;
  averageDuration: number;
  errorRate: number;
  lastUsed: Date;
}

export abstract class BaseModel<TConfig extends BaseModelConfig> {
  protected config: TConfig;
  protected metrics: ModelMetrics;

  constructor(config: TConfig) {
    this.config = config;
    this.metrics = {
      requestCount: 0,
      totalDuration: 0,
      averageDuration: 0,
      errorRate: 0,
      lastUsed: new Date()
    };
  }

  abstract getCapabilities(): ModelCapabilities;
  abstract generateResponse(prompt: string): Promise<string>;
  
  getMetrics(): ModelMetrics {
    return { ...this.metrics };
  }

  protected updateMetrics(duration: number, success: boolean): void {
    this.metrics.requestCount++;
    this.metrics.lastUsed = new Date();
    
    if (success) {
      this.metrics.totalDuration += duration;
      this.metrics.averageDuration = this.metrics.totalDuration / this.metrics.requestCount;
    } else {
      this.metrics.errorRate = (this.metrics.errorRate * (this.metrics.requestCount - 1) + 1) / this.metrics.requestCount;
    }
  }
}

// Specific implementation for Ollama models
export interface OllamaModelConfig extends BaseModelConfig {
  host?: string;
  keepAlive?: string;
  numCtx?: number;
}

export class OllamaModel extends BaseModel<OllamaModelConfig> {
  private client: TypedOllamaClient;

  constructor(config: OllamaModelConfig) {
    super(config);
    this.client = new TypedOllamaClient(config.host);
  }

  getCapabilities(): ModelCapabilities {
    return {
      supportsChat: true,
      supportsCompletion: true,
      supportsEmbedding: false,
      contextWindow: this.config.numCtx || 4096,
      languages: ['en', 'es', 'fr', 'de', 'it', 'pt', 'ru', 'ja', 'ko', 'zh']
    };
  }

  async generateResponse(prompt: string): Promise<string> {
    const startTime = Date.now();
    let success = false;

    try {
      const response = await this.client.generateResponse(
        this.config.model,
        prompt,
        {
          temperature: this.config.temperature,
          top_p: this.config.topP,
          top_k: this.config.topK,
          repeat_penalty: this.config.repeatPenalty,
          num_ctx: this.config.numCtx
        }
      );
      
      success = true;
      return response;
    } finally {
      const duration = Date.now() - startTime;
      this.updateMetrics(duration, success);
    }
  }
}

Building a Complete Application Example

Create a comprehensive CLI application that demonstrates all concepts:

// src/app.ts
import { TypedOllamaClient } from './ollama-client';
import { ConversationService } from './conversation-service';
import { ErrorHandler, OllamaError } from './error-handler';
import { OllamaModel } from './model-interfaces';

      const modelExists = models.some(m => m.name === this.model.config.model);
      if (!modelExists) {

    );

    console.log('💬 Starting conversation. Type "quit" to exit, "stats" for metrics.\n');

    while (true) {
      const input = await this.prompt('You: ');

        const response = await ErrorHandler.withRetry(
          () => this.conversationService.sendMessage(conversationId, input),
          3,
          1000
        );

        console.log(`🤖 Assistant: ${response.content}\n`);
      } catch (error) {

    let size = bytes;
    let unitIndex = 0;

    while (size >= 1024 && unitIndex < units.length - 1) {
      size /= 1024;
      unitIndex++;
    }

    return `${size.toFixed(1)} ${units[unitIndex]}`;
  }

  close(): void {
    this.rl.close();

Testing Your TypeScript Ollama Application

Unit Testing with Jest

Create comprehensive tests for your TypeScript Ollama integration:

// src/__tests__/ollama-client.test.ts
import { TypedOllamaClient } from '../ollama-client';
import { ErrorHandler } from '../error-handler';

describe('TypedOllamaClient', () => {
  let client: TypedOllamaClient;

  beforeEach(() => {
    client = new TypedOllamaClient();
  });

  describe('generateResponse', () => {
    it('should generate a response with proper typing', async () => {
      const response = await client.generateResponse(
        'llama3.2:3b',
        'Hello, world!'
      );

      expect(typeof response).toBe('string');
      expect(response.length).toBeGreaterThan(0);
    });

    it('should handle errors gracefully', async () => {
      await expect(
        client.generateResponse('nonexistent-model', 'test')
      ).rejects.toThrow();
    });
  });

  describe('listModels', () => {
    it('should return typed model information', async () => {
      const models = await client.listModels();
      
      expect(Array.isArray(models)).toBe(true);
      if (models.length > 0) {
        expect(models[0]).toHaveProperty('name');
        expect(models[0]).toHaveProperty('size');
        expect(models[0]).toHaveProperty('details');
      }
    });
  });
});

Integration Testing

Test complete workflows with proper error handling:

// src/__tests__/conversation-service.test.ts
import { TypedOllamaClient } from '../ollama-client';
import { ConversationService } from '../conversation-service';

describe('ConversationService', () => {
  let service: ConversationService;
  let client: TypedOllamaClient;

  beforeEach(() => {
    client = new TypedOllamaClient();
    service = new ConversationService(client);
  });

  it('should create and manage conversations', async () => {
    const conversationId = service.createConversation('llama3.2:3b');
    
    expect(conversationId).toBeDefined();
    expect(typeof conversationId).toBe('string');

    const conversation = service.getConversation(conversationId);
    expect(conversation).toBeDefined();
    expect(conversation?.model).toBe('llama3.2:3b');
  });

  it('should handle conversation messages with proper typing', async () => {
    const conversationId = service.createConversation('llama3.2:3b');
    
    const response = await service.sendMessage(
      conversationId,
      'What is TypeScript?'
    );

    expect(response).toBeDefined();
    expect(response.role).toBe('assistant');
    expect(response.content).toBeDefined();
    expect(response.timestamp).toBeInstanceOf(Date);
  });
});

Performance Optimization and Best Practices

Memory Management

Implement efficient memory usage patterns:

// src/memory-manager.ts
export class MemoryManager {
  private static instance: MemoryManager;
  private conversations: Map<string, any> = new Map();
  private readonly maxConversations = 100;
  private readonly maxMessageHistory = 50;

  static getInstance(): MemoryManager {
    if (!MemoryManager.instance) {
      MemoryManager.instance = new MemoryManager();
    }
    return MemoryManager.instance;
  }

  addConversation(id: string, conversation: any): void {
    // Remove oldest conversation if limit exceeded
    if (this.conversations.size >= this.maxConversations) {
      const oldestId = this.conversations.keys().next().value;
      this.conversations.delete(oldestId);
    }

    // Trim message history if too long
    if (conversation.messages.length > this.maxMessageHistory) {
      conversation.messages = conversation.messages.slice(-this.maxMessageHistory);
    }

    this.conversations.set(id, conversation);
  }

  getConversation(id: string): any {
    return this.conversations.get(id);
  }

  removeConversation(id: string): void {
    this.conversations.delete(id);
  }

  getMemoryUsage(): { conversations: number; totalMessages: number } {
    let totalMessages = 0;
    for (const conversation of this.conversations.values()) {
      totalMessages += conversation.messages.length;
    }

    return {
      conversations: this.conversations.size,
      totalMessages
    };
  }
}

Caching and Performance

Implement smart caching for better performance:

// src/cache-manager.ts
export class CacheManager {
  private cache: Map<string, { data: any; timestamp: number; ttl: number }> = new Map();
  private readonly defaultTTL = 5 * 60 * 1000; // 5 minutes

  set(key: string, data: any, ttl: number = this.defaultTTL): void {
    this.cache.set(key, {
      data,
      timestamp: Date.now(),
      ttl
    });
  }

  get(key: string): any | null {
    const entry = this.cache.get(key);
    if (!entry) return null;

    if (Date.now() - entry.timestamp > entry.ttl) {
      this.cache.delete(key);
      return null;
    }

    return entry.data;
  }

  clear(): void {
    this.cache.clear();
  }

  cleanup(): void {
    const now = Date.now();
    for (const [key, entry] of this.cache.entries()) {
      if (now - entry.timestamp > entry.ttl) {
        this.cache.delete(key);
      }
    }
  }
}

Deployment and Production Considerations

Docker Configuration

Create a production-ready Docker setup:

# Dockerfile
FROM node:18-alpine

WORKDIR /app

# Install dependencies
COPY package*.json ./
RUN npm ci --only=production

# Copy source code
COPY dist ./dist
COPY src ./src

# Create non-root user
RUN addgroup -g 1001 -S nodejs
RUN adduser -S ollama -u 1001

USER ollama

EXPOSE 3000

CMD ["node", "dist/app.js"]

Environment Configuration

Set up proper environment management:

// src/config.ts
export interface AppConfig {
  ollama: {
    host: string;
    timeout: number;
    retries: number;
  };
  app: {
    port: number;
    logLevel: string;
    environment: string;
  };
  cache: {
    ttl: number;
    maxSize: number;
  };
}

export function loadConfig(): AppConfig {
  return {
    ollama: {
      host: process.env.OLLAMA_HOST || 'http://localhost:11434',
      timeout: parseInt(process.env.OLLAMA_TIMEOUT || '30000'),
      retries: parseInt(process.env.OLLAMA_RETRIES || '3')
    },
    app: {
      port: parseInt(process.env.PORT || '3000'),
      logLevel: process.env.LOG_LEVEL || 'info',
      environment: process.env.NODE_ENV || 'development'
    },
    cache: {
      ttl: parseInt(process.env.CACHE_TTL || '300000'),
      maxSize: parseInt(process.env.CACHE_MAX_SIZE || '1000')
    }
  };
}

Monitoring and Logging

Structured Logging

Implement comprehensive logging for production monitoring:

// src/logger.ts
export enum LogLevel {
  DEBUG = 0,
  INFO = 1,
  WARN = 2,
  ERROR = 3
}

export interface LogEntry {
  timestamp: string;
  level: LogLevel;
  message: string;
  context?: any;
  error?: Error;
}

export class Logger {
  constructor(private level: LogLevel = LogLevel.INFO) {}

  debug(message: string, context?: any): void {
    this.log(LogLevel.DEBUG, message, context);
  }

  info(message: string, context?: any): void {
    this.log(LogLevel.INFO, message, context);
  }

  warn(message: string, context?: any): void {
    this.log(LogLevel.WARN, message, context);
  }

  error(message: string, error?: Error, context?: any): void {
    this.log(LogLevel.ERROR, message, context, error);
  }

  private log(level: LogLevel, message: string, context?: any, error?: Error): void {
    if (level < this.level) return;

    const entry: LogEntry = {
      timestamp: new Date().toISOString(),
      level,
      message,
      context,
      error
    };

    console.log(JSON.stringify(entry, null, 2));
  }
}
