Creating an Application

Create a VCLight app instance in src/app/app.ts:

import VCLight from "vclight";

const app = new VCLight({
    onError: async (_request, response) => {
        response.status = 500;
        response.response = "Internal Server Error";
        response.end = true;
    }
});

export default app;

Then register middleware with app.use(...).

import router from "./router";

app.use(router);

Entry files

Choose one or more handlers based on your deployment target.

Vercel

import app from "./app/app";

export default app.vercelHandler();

Vercel Functions

Vercel Functions (Edge Runtime) require wrapping with a fetch property:

import app from "./app/app";

export default {
    fetch: app.vercelFunctionHandler()
};

Netlify

import app from "../../src/app/app";

export default app.netlifyHandler();

Cloudflare Workers

import app from "./app/app";

export default app.cloudflareHandler();

Node HTTP

import * as http from "http";
import app from "./app/app";

const server = http.createServer();
server.on("request", app.httpHandler());
