CopilotTextarea

CopilotTextarea is a React component that provides an AI-powered textarea with autocompletion functionality. It's a fork of CopilotKit, designed to allow for more flexible and custom implementations without being tied to a specific cloud solution.

Installation

To install CopilotTextarea, run the following command:

``bash
npm install copilot-react-textarea

const handleChange = (e: ChangeEvent) => {
setValue(e.target.value);
};

return (
placeholder="Enter text here..."
className="min-h-[60px] w-full rounded-md border border-input bg-transparent px-3 py-2 text-sm shadow-sm placeholder:text-muted-foreground focus-visible:outline-none focus-visible:ring-1 focus-visible:ring-ring disabled:cursor-not-allowed disabled:opacity-50"
rows={5}
cols={50}
onChange={handleChange}
value={value}
textareaPurpose="chat"
createSuggestionFunction={async (data: {
textAfterCursor: string;
textBeforeCursor: string;
}): Promise => {
// Implement your autocomplete logic here
return "Autocomplete suggestion";
}}
insertionOrEditingFunction={async (editorState: any): Promise> => {
// Implement your insertion or editing logic here
const stream = new ReadableStream({
start(controller) {
controller.enqueue("Inserted text");
controller.close();
},
});
return stream;
}}
onKeyDown={(event) => {

Motivation

CopilotTextarea is a fork of CopilotKit, created with the motivation to provide more flexibility in custom implementations. The original CopilotKit was tightly coupled with their cloud solution, which limited its use in projects that required custom backend integrations or self-hosted solutions.

By forking the project, we've made it possible to use these open-source components with your own implementation of autocomplete and text generation functions. This allows developers to integrate CopilotTextarea with their preferred AI services or custom backend solutions without being locked into a specific cloud provider.
