title	Quickstart: CopilotTextarea
description	How to integrate CopilotTextarea into your application

Setup

Intall CopilotKit

Install the CopilotKit frontend packagess:

```bash npm npm i @copilotkit/react-core @copilotkit/react-textarea ``` ```bash yarn yarn add @copilotkit/react-core @copilotkit/react-textarea ``` ```bash pnpm pnpm add @copilotkit/react-core @copilotkit/react-textarea ```

Setup the frontend

A CopilotProvider must wrap all components which interact with CopilotKit.

For simplicity's sake, it's recommended you wrap a CopilotProvider around your entire application:

"use client";
import { CopilotProvider } from "@copilotkit/react-core";

export default function RootLayout({children}) {
  return (
    <CopilotProvider chatApiEndpoint="/path_to_copilotkit_endpoint/see_below">
      {children}
    </CopilotProvider>
  );
}

Setup the CopilotKit Backend Endpoint:

Setup a backend endpoint (and pass its URL as the chatApiEndpoint argument to CopilotProvider, as above).

See Quickstart-Backend

Provide context

You likely want to provide external context to inform CopilotTextarea completions, insertions, and edits.

You can do so through the useMakeCopilotReadable and useMakeCopilotDocumentReadable react hooks. See their respective documentation for additional details.

In particular, you can specify categories which bind specific context to specific textareas, and not to others.

const employeeContextId = useMakeCopilotReadable(employeeName);

// Pass a parentID to maintain a hiearchical structure.
// Especially useful with child React components, list elements, etc.
useMakeCopilotReadable(workProfile.description(), employeeContextId);
useMakeCopilotReadable(metadata.description(), employeeContextId);

const document: DocumentPointer = {
  id: "2",
  name: "Travel Pet Peeves",
  sourceApplication: "Google Docs",
  iconImageUri: "/images/GoogleDocs.svg",
  getContents: () => { return getThisDocumentContents() },
} as DocumentPointer;

function SomeComponent(): JSX.Element {
  useMakeCopilotDocumentReadable(document);
  // ...
}

Integrate a CopilotTextarea

CopilotTextarea is configured essentially identically to a standard react <textarea />.

The primary difference is the additional autosuggestionsConfig variable, which provides copilot-specific configurations.

See the CopilotTextarea documentation for all parameters.

import { CopilotTextarea } from "@copilotkit/react-textarea";
import { useState } from "react";

export function SomeReactComponent(): JSX.Element {
  const [text, setText] = useState("");

  return (
    <>
      <CopilotTextarea
        className="px-4 py-4"
        value={text}
        onValueChange={(value: string) => setText(value)}
        placeholder="What are your plans for your vacation?"
        autosuggestionsConfig={{
          textareaPurpose: "Travel notes from the user's previous vacations. Likely written in a colloquial style, but adjust as needed.",
          chatApiConfigs: {
            suggestionsApiConfig: {
              forwardedParams: {
                max_tokens: 20,
                stop: [".", "?", "!"],
              },
            },
          },
        }}
      />
    </>
  );
}
