Micronaut is a JVM-based framework that let you develop modular and lightweight applications. It is just like a toolbox that enables you to do several tasks in no time such as fast startup time, minimal use of reflection, a reduced memory footprint, easy unit testing, and minimal use of proxies. Micronaut is developed by OCI and is often used to create microservices quickly and easily.
Its features such as the ability to use the compile time to do something productive, make it different and unique from other services. Unlike other frameworks that make use of proxies and reflection to perform dependency injection, Micronaut uses its compile time to build its dependency injection data which results in smaller memory footprint and faster application.
Another best thing in Micronaut is its major support to reactive programming for servers as well as clients. Here are several features that make it a worthy framework for developing cloud-native applications. It not only supports multiple service discovery tools such as Consul and Eureka but can also work effectively with various tracing systems such as Jaeger and Zipkin.
Let’s discuss in detail how does it work and help in building faster and quick web and mobile-based applications.
Fast Startup with Low Memory Consumption
Unlike other IoC frameworks that loads every single detail of the application such as loading time, cache reflection, constructor, the method, applications developed using Micronaut does not depend on the size of the codebase. That is why application startup time and memory consumption time is less.
Supports Renowned Programming Languages
One of the best features of Micronaut is that it supports different programming languages that are mostly used to build and run an application. These languages can also be used to develop various APIs.
Builds Dependency Injection in No Time
Micronaut utilizes its compile time to build a dependency injection and does not use a reflection to develop an API. This is how it saves a lot of developers’ time.
Develops Fully Reactive and Non-blocking Apps
The best thing in Micronaut is that it supports any framework that implements Reactive streams be it Reactor or RxJava.
Built-in-support for Cloud
Micronaut supports common services like discovery, cloud runtime, and distributed tools. The reason behind that is Micronaut has a built-in support feature for Cloud. It supports:
- Google Cloud Platform
- Netflix Eureka
- JAEGER — open source, end-to-end distributed tracing
- Zipkin — distributed tracing system
Design Resilient Microservices
As a developer, you might know that in a distributed microservice environment, a better planning is always required to handle difficult situations. When it comes to using Micronaut, it is fully prepared for handling such situations. It has a built-in support for the services that fall apart. It retries to bring it back using the Circuit Breaker, and if still, the services are down after numerous attempts than it lets you plan a strategy in a better way.
Fast Data-Access Configuration
Using Micronaut, you can automatically configure your favorite API and data access toolkit anytime such as Mongo DB, Redis, SQL, Hibernate, Neo4J, and Cassandra so that it is easier for you to write your integrations.
Easily Develop Serverless Applications
Micronaut helps to develop serverless applications such as AWS Lambda service. It is because it does not need extra time and effort and make use of Aspect-Oriented Programming and less overhead compile-time Dependency Injection.
How Micronaut is different from Grails and Spring?
Micronaut is different from other technology due to its outstanding features such as:
- Reduced memory footprint
- Fast startup time
- Easy unit testing
- Minimal use of reflection
- Minimal use of proxies
- Frameworks such as Spring and Grails were not designed to run on serverless functions, low memory-footprint Microservices, and Android Apps. However, Micronaut is designed in a way that it is perfectly suitable and can easily address these concerns.
- Micronaut uses Java annotation processors which can be further used in any JVM based language to precompile the necessary data and perform dependency injection. Micronaut also defines the AOP proxies and autoconfigures your application so that it can run on any microservice environment.
- Micronaut is designed better than rails and Spring, though inspired from all the positive aspects of the same. It aids developers to work efficiently by using compile time to perform dependency injection and enormous built-in features.
Micronaut is an amazing framework that not only let developers to work quickly and easily, but also allow better API development in less time. However, before you start with this framework, it is important to understand its do’s and don’ts, advantages and disadvantages so that you can make the most benefit out of it. lastly, you should hire a software development company to develop faster applications as they provide you latest solutions and are up-to-date with the trending technology.
