2
3app.post('/send', async (req, res) => {
4    const fakeData = {
5        Name: "Md. Muhtasim Fuad Fahim",
6        Email: "mdmuhtasim.fahim@gmail.com",

10    console.log("Producer: ", produce);
11    return res.status(200).send("Done!");
12});

service-2/server.js

4    await RMQSubStream("FAKE_DATA").then((data) => {
5        console.log("CONSUME: ", data);

7})();

service-1/.env & service-2/.env

1AMQP_URL = "amqp://localhost"
