@nwire/http-express

Express interop — drop Nwire routes into Express apps; use Express middleware inside Nwire interfaces.

What it is

About 50 LOC of real adapter code. toExpress(api) compiles a Nwire HTTP interface into Express middleware you mount under any path; fromExpress(mw) bridges any Express middleware (helmet, morgan, passport.authenticate) into Nwire's .use(...) chain. The migration story for teams that can't rewrite.

Install

pnpm add @nwire/http @nwire/http-express

express is a peer dep — bring whatever version you already have (4 or 5).

Within nwire-app

For developers using this package as part of the Nwire stack. Mount Nwire-app-backed interfaces into an Express host so an existing service can adopt Nwire incrementally — the Nwire side still gets plugin lifecycle, envelope propagation, and OpenAPI.

import express from "express";
import { createApp } from "@nwire/forge";
import { http } from "@nwire/http";
import { toExpress } from "@nwire/http-express";

const app = createApp("learnflow").module(stations);
const api = http("api").wire(stationRoutes);

const host = express();
host.use("/api", toExpress(api, { app }));
host.listen(3000);

API

• toExpress(httpInterface, options?) — Nwire HTTP interface → Express request handler.
• fromExpress(middleware) — Express middleware → Nwire .use(...) step.
