Implementation

API Function

Gatsby supports serverless functions placed under the /src/api directory. Create a function for completions in src/api/code-completion.ts:

src/api/code-completion.ts

import type {GatsbyFunctionRequest, GatsbyFunctionResponse} from 'gatsby';
import {CompletionCopilot, type CompletionRequestBody} from 'monacopilot';

const copilot = new CompletionCopilot(process.env.MISTRAL_API_KEY!, {
    provider: 'mistral',
    model: 'codestral',
});

export async function handler(
    req: GatsbyFunctionRequest,
    res: GatsbyFunctionResponse,
) {
    if (req.method !== 'POST') {
        res.status(405).json({error: 'Method not allowed'});
        return;
    }

    try {
        const body: CompletionRequestBody = JSON.parse(req.body);
        const completion = await copilot.complete({body});
        res.status(200).json(completion);
    } catch (error) {
        res.status(500).json({error: 'Internal Server Error', details: error});
    }
}

Editor Component

Create an Editor component:

src/components/Editor.tsx

import { useEffect, useRef } from "react";
import MonacoEditor from "@monaco-editor/react";
import {
  registerCompletion,
  type CompletionRegistration,
  type Monaco,
  type StandaloneCodeEditor,
} from "monacopilot";

export default function Editor() {
  const completionRef = useRef<CompletionRegistration | null>(null);

  const handleMount = (editor: StandaloneCodeEditor, monaco: Monaco) => {
    completionRef.current = registerCompletion(monaco, editor, {
      endpoint: "/api/code-completion",
      language: "javascript",
    });
  };

  useEffect(() => {
    return () => {
      completionRef.current?.deregister();
    };
  }, []);

  return <MonacoEditor language="javascript" onMount={handleMount} />;
}

Page Component

Create your page component:

src/pages/index.tsx

import * as React from "react";
import Editor from "../components/Editor";

export default function IndexPage() {
  return (
    <main style={{ height: "100vh", width: "100vw" }}>
      <h1>Monacopilot Gatsby Example</h1>
      <Editor />
    </main>
  );
}

Environment Variables

Create a .env file in your project root:

.env

MISTRAL_API_KEY=your_mistral_api_key_here

Obtain your Mistral API Key from the Mistral AI Console.

Monacopilot supports multiple AI providers and models. For details on available options and configuration, see the Changing the Provider and Model documentation.
