Streaming

Now lets add streaming support...

import { ChatPrompt } from '@microsoft/spark.ai';
import { OpenAIChatModel } from '@microsoft/spark.openai';

const prompt = new ChatPrompt({
    instructions: [
        'you are an assistant that helps find the perfect emoji to use for a given situation.',
        'you will only respond with emojis.',
    ].join('\n'),
    model: new OpenAIChatModel({
        model: 'gpt-4o',
        apiKey: process.OPENAI_API_KEY,
        stream: true,
    }),
});

(async () => {
    await prompt.chat('having a great day!', (chunk) => {
        process.stdout.write(chunk); // 😄🌞🎉
    });

    process.stdout.write('\n');
})();
