REST Services With Apache Camel

Microservices are becoming a very popular architectural style for developing greenfield applications and also for brownfield solutions. People are moving away from the monolith solutions due to added advantages like faster development and go-to-market, increased adoption of containerization and small teams, and a lighter codebase. 

You can use either Spring Boot, Quarkus, or Lagom frameworks to develop the REST services. I would like to show how we can use Apache Camel, a leading opensource integration framework, to write REST services easier and quicker using the REST domain-specific language (DSL).

Tutorial: Reactive Spring Boot Part 1, Building a Kotlin REST Service

Get some REST!

Last month, I presented a live demo at SpringOne Platform, showing how to build a Spring Boot application that displays real-time prices, using Spring (obviously), Kotlin, and JavaFX. The live demo was recorded and is available as a 70-minute video, but I thought it might be easier to digest as a series of shorter videos with an accompanying blog post, explaining each of the steps more slowly and in more detail.

This is the first step: creating a reactive Spring Boot service with Kotlin.

How to Set Up a REST Service or a Web Application in Django

Introduction to Django and REST

Django is a very versatile framework, primarily used for developing web applications, but it is also widely used in creating mobile app backends and REST APIs, among other things. Here we will take a quick look at how to make these things possible using Django.

As you all probably know, REST stands for “Representational State Transfer.” Basically, what happens is that a user (or some software agent on one end) provides some input (or performs some activity) and the result of those inputs (or activities) are sent to the server side using a protocol that allows a request to be sent to the server (in most cases a HTTP protocol is used, but it doesn't need to be HTTP, as long as it can support a request/response scheme). The server, on receiving the request, makes appropriate changes to the state of the system (hence we call it “State Transfer”).
