However, every time you update the `message`, your component re-renders. When your component re-renders, the code inside of it runs again from scratch. -A new `options` object is created from scratch on every re-render of the `ChatRoom` component. React sees that the `options` object is a _different object_ from the `options` object created during the last render. This is why it re-synchronizes your Effect (which depends on `options`), and the chat re-connects as you type. -**This problem only affects objects and functions. In JavaScript, each newly created object and function is considered distinct from all the others. It doesn't matter that the contents inside of them may be the same!** -// During the first renderconst options1 = { serverUrl: 'https://localhost:1234', roomId: 'music' };// During the next renderconst options2 = { serverUrl: 'https://localhost:1234', roomId: 'music' };// These are two different objects!console.log(Object.is(options1, options2)); // false -**Object and function dependencies can make your Effect re-synchronize more often than you need.** -This is why, whenever possible, you should try to avoid objects and functions as your Effect's dependencies. Instead, try moving them outside the component, inside the Effect, or extracting primitive values out of them. -#### Move static objects and functions outside your component[](#move-static-objects-and-functions-outside-your-component "Link for Move static objects and functions outside your component ") -If the object does not depend on any props and state, you can move that object outside your component: -const options = { serverUrl: 'https://localhost:1234', roomId: 'music'};function ChatRoom() { const [message, setMessage] = useState(''); useEffect(() => { const connection = createConnection(options); connection.connect(); return () => connection.disconnect(); }, []); // ✅ All dependencies declared // ... -This way, you _prove_ to the linter that it's not reactive. It can't change as a result of a re-render, so it doesn't need to be a dependency.

It provides a unified API for working with different AI models, making it easier to integrate AI capabilities into your applications. - -Key components of the AI SDK include: - -1. **AI SDK Core**: This provides a standardized way to generate text, structured objects, and tool calls with Large Language Models (LLMs). -2. **AI SDK UI**: This offers framework-agnostic hooks for building chat and generative user interfaces. - ---- - -## API Design - -The AI SDK provides several core functions and integrations: - -- `streamText`: This function is part of the AI SDK Core and is used for streaming text from LLMs. It's ideal for interactive use cases like chatbots or real-time applications where immediate responses are expected. -- `generateText`: This function is also part of the AI SDK Core and is used for generating text for a given prompt and model. It's suitable for non-interactive use cases or when you need to write text for tasks like drafting emails or summarizing web pages. -- `@ai-sdk/openai`: This is a package that provides integration with OpenAI's models. It allows you to use OpenAI's models with the standardized AI SDK interface. - -### Core Functions - -#### 1. `generateText` - -- **Purpose**: Generates text for a given prompt and model. -- **Use case**: Non-interactive text generation, like drafting emails or summarizing content. - -**Signature**: -```typescript -function generateText(options: { -model: AIModel; -prompt: string; -system?: string; -}): Promise<{ text: string; finishReason: string; usage: Usage }> -``` - -#### 2. `streamText` - -- **Purpose**: Streams text from a given prompt and model. -- **Use case**: Interactive applications like chatbots or real-time content generation. - -**Signature**: -```typescript -function streamText(options: { -model: AIModel; -prompt: string; -system?: string; -onChunk?: (chunk: Chunk) => void; -onFinish?: (result: StreamResult) => void; -}): StreamResult -``` - -### OpenAI Integration - -The `@ai-sdk/openai` package provides integration with OpenAI models: - -```typescript -import { openai } from '@ai-sdk/openai' - -const model = openai('gpt-4o') -``` - ---- - -## Examples - -### 1.

The user initiates the login process with the client application. - 2. The client application requests authorization from the authorization server. - 3. The authorization server prompts the user to log in and give consent. - 4. The user provides their credentials and grants permission. - 5. The authorization server returns an authorization code to the client. - 6. The client exchanges the authorization code for an access token. - 7. The authorization server returns the access token to the client. - 8. The client requests resources from the resource server using the access token. - 9. The resource server returns the requested resources. - 10. The client application presents the retrieved resources or data to the user. - - This flow ensures that the client application never sees the user's credentials, enhancing security.
