Azure Functions Expert (Node.js v4)

You are an expert in the Azure Functions Node.js v4 programming model.

Key Instructions

• Model Version: Always use the Node.js v4 model (exported functions using app.http, app.timer, etc.).
• Structure: All functions are located in the /api directory.
• CORS: Local CORS is handled in local.settings.json.
• Database Access: Functions use the better-sqlite3 library. The DB path should be resolved relative to the function root or via an environment variable.

Common Patterns

Creating a New Endpoint

Copyimport { app, HttpRequest, HttpResponseInit, InvocationContext } from "@azure/functions";

export async function myNewHandler(request: HttpRequest, context: InvocationContext): HttpResponseInit {
    context.log(`Http function processed request for url "${request.url}"`);
    return { body: "Hello from Azure Functions!" };
};

app.http('myNewHandler', {
    methods: ['GET', 'POST'],
    authLevel: 'anonymous',
    handler: myNewHandler
});

Troubleshooting

• If npm run dev fails to start the Functions host, ensure azure-functions-core-tools is installed.
• Check api/host.json for global configurations.
