@nodeboot/starter-openai v1.1.5

OpenAI Starter for NodeBoot - User Guide

Introduction

The @nodeboot/starter-openai package enables seamless integration of OpenAI into NodeBoot-based applications. It provides a structured way to configure the OpenAI client using dependency injection (DI) and app-config.yaml.

This package can be used with any AI platform compatible with OpenAI, by providing the respective platform API url and key.

Installation

To use the OpenAI starter in your project, install it via npm or yarn:

npm install openai @nodeboot/starter-openai

or

pnpm add openai @nodeboot/starter-openai

Configuration

1. Define OpenAI Configuration in app-config.yaml

Ensure that your app-config.yaml file includes the necessary OpenAI integration settings:

integrations:
    openai:
        apiKey: ${OPENAI_API_KEY}
        organization: "your-org-id"
        project: "your-project-id"
        baseURL: "https://api.openai.com/v1/"
        timeout: 5000
        maxRetries: 2

• apiKey: Your OpenAI API key (required).
• organization: Your OpenAI organization ID (optional).
• project: OpenAI project ID (optional).
• baseURL: Custom base URL for the API (defaults to OpenAI's endpoint).
• timeout: Request timeout in milliseconds.
• maxRetries: Maximum number of retry attempts for failed requests.

2. Enable OpenAI in Your Application

In your main application class, use the @EnableOpenAI() decorator to enable OpenAI integration:

import "reflect-metadata";
import {Container} from "typedi";
import {NodeBoot, NodeBootApp, NodeBootApplication, NodeBootAppView} from "@nodeboot/core";
import {ExpressServer} from "@nodeboot/express-server";
import {EnableDI} from "@nodeboot/di";
import {EnableComponentScan} from "@nodeboot/scan";
import {EnableOpenAI} from "@nodeboot/starter-openai";

@EnableDI(Container)
@EnableOpenAI()
@EnableComponentScan()
@NodeBootApplication()
export class MyApplication implements NodeBootApp {
    start(): Promise<NodeBootAppView> {
        return NodeBoot.run(ExpressServer);
    }
}

3. Inject OpenAI Client into Your Services

Once enabled, you can inject the OpenAI client into your services to interact with OpenAI's APIs:

import {Inject, Service} from "typedi";
import OpenAI from "openai";

@Service()
export class MyService {
    constructor(@Inject(() => OpenAI) private readonly openAiClient: OpenAI) {}

    async generateText(prompt: string): Promise<string> {
        const response = await this.openAiClient.chat.completions.create({
            model: "gpt-4",
            messages: [{role: "user", content: prompt}],
            max_tokens: 100,
        });
        return response.choices[0].message.content;
    }
}

Verifying the Integration

1. Ensure your app-config.yaml contains the correct OpenAI API key and settings.
2. Run your NodeBoot application (pnpm start).
3. Check logs to confirm the OpenAI client was successfully configured.

Troubleshooting

Issue: "OpenAI client was not created"

Solution: Ensure that app-config.yaml includes the integrations.openai section with the correct apiKey and baseURL.

Issue: "401 Unauthorized when accessing OpenAI API"

Solution: Verify that the API key is correctly set and has the required permissions.

Conclusion

The @nodeboot/starter-openai package simplifies OpenAI integration in NodeBoot applications. By following this guide, you can configure and use OpenAI effectively within your services.
