,

It’s common for websites to have a subscription button, where you can pass along your email address, and you’ll receive emails every week, month, or day. Sometimes, these are automated emails, and sometimes they are custom posts written by an editor.

It’s also common to pay for this service, sometimes extortionately. In this article, I’ll show you it’s pretty easy to create your own, although you will obviously still have to pay for hosting. Let’s look at how to create an email subscription service with MongoDB and Node.JS.

How to Create a Messaging Server in Low-Code

,

In this sample, we will implement the server-side of a client-server style messaging app. To do so, you could use your preferred programming language, but for speed, we’ll use Linx, a low-code developer tool for backend APIs, integrations, and automation.

For a quick review of Linx and how it works, see this video.

Scope

We will implement some web methods, which will be useful for creating a messaging client. However, the following items fall outside the scope of this sample:

Implementing MongoDB to Elastic Search 7.X Data Pipeline

,

In this article, we will see how to implement a data pipeline from an application to Mongo DB database and from there into an Elastic Search keeping the same document ID using Kafka connect in a Microservice Architecture. In recent days and years, all the microservices architectures are asynchronous in nature and are very loosely coupled. At the same time, the prime approach to have minimum code (minimum maintenance and cost), no batch systems (real-time data), and promising performance without data loss fear. Keeping all the features in mind Kafka and Kafka connect is the best solution so far to integrate different sources and sinks in one architecture to have very robust and reliable results.

We will Depp drive and implement such a solution using Debezium Kafka connect to achieve a very robust pipeline of data from one application into Mongo and then into Elastic cluster.
