mockpressx builds a parallel Express app from an existing app’s top-level route table (via routecheckx) and serves mock JSON with optional latency and random fault injection.

Usage

import express from "express";
import { mockpressx } from "mockpressx";

const app = express();
app.get("/api/users", (_req, res) => res.json([]));

const mock = mockpressx(app, { latencyMs: 50, errorRate: 0.01 });
mock.listen(4000);
