Express Adapter

Use @proof-computer/baran-express for Express apps deployed through Baran.

Install​

npm install @proof-computer/baran-express express
npm install --save-dev typescript tsx @types/node @types/express

Minimal App​

import express from "express";
import {serveBaranExpress} from "@proof-computer/baran-express";

const app = express();

app.get("/", (_request, response) => {
  response.type("html").send("<h1>Baran Express</h1><p>ok</p>");
});

void serveBaranExpress(app).catch((error) => {
  console.error(error);
  process.exit(1);
});

The adapter mounts Baran health, status, and challenge endpoints and starts the server with the runtime config supplied at deploy time.

What The Adapter Provides​

  • GET /health
  • GET /status
  • GET /.well-known/proofcomputer/challenge?nonce=<value>
  • runtime TLS setup when deploy-time config enables job-owned TLS
  • registration and certificate helper wiring through the runtime package

Local Development​

Run your app locally with certificate automation disabled or with local test values. Do not use production Acurast, payment, DNS, or PROOF secrets for a local-only Express preview.

For the packaged demo app, use proof baran launch-demo rather than copying demo renderer code into your project.
