How to Produce and Consume a message

Memphis abstracts the need for external serialization functions and embeds them within the SDK.

In node.js, we can simply produce an object. Behind the scenes, the object will be serialized based on the attached schema and data format - protobuf.

Example schema:

	"$schema": "http://json-schema.org/draft-04/schema#",
	"title": "contact_details",
	"type": "object",
	"properties": {
		"fname": {
			"type": "string"
		"lname": {
			"type": "string"


const memphis = require("memphis-dev");

(async function () {
    try {
        await memphis.connect({
            host: "MEMPHIS_BROKER_URL",
            username: "APPLICATION_USER",
            password: "PASSWORD",
            // accountId: ACCOUNT_ID //*optional* In case you are using Memphis.dev cloud
        const producer = await memphis.producer({
            stationName: "STATION_NAME",
            producerName: "PRODUCER_NAME"
        var payload = {
            fname: "Daniel",
            lname: "Craig",
        try {
            await producer.produce({
                message: payload
        } catch (ex) {
    } catch (ex) {
