Spring Boot vs Vert.x: What are the differences?

Spring Boot and Vert.x are both popular frameworks used in developing web applications. Let's explore the key differences between them.

  1. Concurrency Model: One of the major differences between Spring Boot and Vert.x lies in their concurrency models. Spring Boot follows a traditional thread-based model, where each request is handled by a separate thread. On the other hand, Vert.x utilizes a non-blocking event-driven model, where requests are handled asynchronously without blocking the main thread. This makes Vert.x more efficient in handling multiple concurrent requests and enables better utilization of system resources.

  2. Programming Language Support: Spring Boot primarily focuses on Java, while providing support for other JVM-based languages such as Kotlin and Groovy. Vert.x, on the other hand, offers polyglot support and can be used to develop applications in multiple programming languages including Java, JavaScript, Kotlin, Groovy, and more. This flexibility gives developers the freedom to choose the language they are most comfortable with.

  3. Scalability: When it comes to scalability, Vert.x has a clear advantage. It is designed to handle massive loads and can easily scale both vertically and horizontally. Vert.x's event-driven architecture allows for efficient scaling across multiple cores and even across multiple servers, making it a suitable choice for high-performance applications. Spring Boot, while capable of scaling, requires additional setup and configuration to achieve the same level of scalability.

  4. Startup Time: Vert.x has a significantly faster startup time compared to Spring Boot. This is mainly because Vert.x is lightweight and only loads the necessary components at runtime, resulting in quicker application startup. On the other hand, Spring Boot has a larger footprint and requires more initialization time due to its extensive auto-configuration features. For applications that require fast startup times, Vert.x is a preferred choice.

  5. Community and Ecosystem: Spring Boot has a larger and more mature community compared to Vert.x. It has been around for a longer time and has a vast number of resources, tutorials, and libraries available. Spring Boot also has strong integration with other Spring projects, making it easier to build complex enterprise applications. While Vert.x has a growing community, it might not have the same level of support and extensive ecosystem as Spring Boot.

  6. Architectural Style: Spring Boot is based on the traditional layered architecture, where applications are typically built with separate layers for presentation, business logic, and data access. Vert.x, on the other hand, encourages a more reactive and event-driven architecture. It promotes building applications that react to events and messages, allowing for a more responsive and resilient system. This architectural difference can influence the design and development approach for developers.

In summary, Spring Boot, built on the Spring framework, follows a convention-over-configuration approach, providing a comprehensive and opinionated solution for building robust, enterprise-level applications. On the other hand, Vert.x is an event-driven, reactive framework designed for building lightweight, high-performance applications with a focus on concurrency and scalability.

Hello, I am a fullstack web developer. I have been working for a company with Java/ Spring Boot and client-side JavaScript(mainly jQuery, some AngularJS) for the past 4 years. As I wish to now work as a freelancer, I am faced with a dilemma: which stack to choose given my current knowledge and the state of the market?

I've heard PHP is very popular in the freelance world. I don't know PHP. However, I'm sure it wouldn't be difficult to learn since it has many similarities with Java (OOP). It seems to me that Laravel has similarities with Spring Boot (it's MVC and OOP). Also, people say Laravel works well with Vue.js, which is my favorite JS framework.

On the other hand, I already know the Javascript language, and I like Vue.js, so I figure I could go the fullstack Javascript route with ExpressJS. However, I am not sure if these techs are ripe for freelancing (with regards to RAD, stability, reliability, security, costs, etc.) Is it true that Express is almost always used with MongoDB? Because my experience is mostly with SQL databases.

The projects I would like to work on are custom web applications/websites for small businesses. I have developed custom ERPs before and found that Java was a good fit, except for it taking a long time to develop. I cannot make a choice, and I am constantly switching between trying PHP and Node.js/Express. Any real-world advice would be welcome! I would love to find a stack that I enjoy while doing meaningful freelance coding.

Hi Eva, As you have solid experience with Spring already, you should jump into freelancing with that. It would be quite stressful to start freelancing with a tech stack you don't know well. Then in the background you can keep learning/practicing an alternative and switch over when you are confident enough (eg. 0.5-1 year later). I think you should learn Laravel as you already like it and find it easier. Express has better performance but that is not required for most of the small freelancer projects.

Looking at current technological trends and rise of JavaScript, you cannot go wrong with JavaScript. - There's an abundance of libraries to get most things done - You can use JavaScript for both the frontend and the backend - this allows you potentially share your logic/models/code across both stacks - A dynamic/interpreted language such as JavaScript is great for serverless (there's somewhat of a trend towards serverless aswell - especially in modern projects) - If you like/need static typing, you can always migrate seemlessly to Typescript - VueJS is a lightweight framework (compared to Angular), it has more GitHub stars and most would argue it's easier to work with (beginner friendly). Additionally most modern webapps do not use JQuery anymore (even though a lot of legacy projects continue to do so). You don't need JQuery if you use Vue/Angular/React

Additionally it doesn't seem like performance is a hugely important metric in your scenario, so JavaScript would suffice.

Note: These are all my opinions and what I've seen in the current market when recently searching for jobs.

I think Patrik and Alex are right: if you're comfortable with Spring Boot already, you'll be more productive right from the start.

If you wish to learn something else besides, both Laravel and Express are good choices. They aren't in the same category of frameworks: Laravel is an all-in-one solution, while Express is more like "build your own stack from different parts". Which implies that you can use whatever you want as a database engine: MySQL or PostgreSQL are perfectly valid choices (in my school, we teach Express with MySQL, because SQL is still a big thing here in France, and a sought-after skill). You can use Sequelize or TypeORM which support all major SQL DBMS.

Express is widely used, but if you're seeking the JavaScript equivalent of Spring Boot or Laravel, you probably want to look at NestJS. The only potential downside is that it's still young, maintained by a small commmunity, compared to those behind Spring Boot and Laravel.

Bottom line: using a stack tech, that you enjoy and are comfortable with, matters. Spring Boot + Vue.js seem perfectly fine to me. But do forget jQuery if you're using Vue.js, React or Angular, because it will definitely bring more harm than good!

Hi as someone who employs and select developers i agree with a lot almost sayed but think of what are your strengths and where you are or better where your customers are. If you search for big enterprise projects spring boot is ok sql is must and html css as well. if you want to go more to internet related companies (like airbnb, what sup, facebook ) or similar (and not asia) then react is a must node js as well. The libraries tools etc which are used you need to adopt fast. If asia then VUE is a must. but if you like small projects with individuals or like wordpress or similar then you can learn php but i think in 2020 it is wasted time. Same for python in that area. and i also see that we often have problem that developer at least must understand docker docker compose better as it works with kubernetes ,.. just my 5 cents

I would definitely recommend you to go with Spring Boot + AngularJS + jQuery. Reasons: 1- You have an experience of 4 years with the above-mentioned stack. 2- As you mentioned that you wish to work as a freelancer, your stack is the perfect one for finding good bids with a little less effort than that of PHP + Laravel + Vue.js.

in order to stay employable, I'd work with something you can deliver with. if I'd be your client and you'd have to get comfortable with a new stack, I would 100% not pay you for this startup time. learn new stuff in your free-time. or set aside time for learning.

that said, if you want to reorientate, php (even though i personally hate it) is extremely wide spread. but so are java and nodejs. so I'm not a fan of that argument... i recommend building something in each language, and see what you enjoy more. for me it was nodejs, because I already enjoy frontend JavaScript, and appreciate the ecosystem and community.

regarding expressjs and mongodb: yes, it is a goto solution for a lot of tutorials, because its as simple as it gets. especially wben using something like monk. BUT if you want to use mysql, posgres or similar, check out TypeORM, Prism or another ORM-like solution. you can use any db with express, and there's plenty of abstraction layers, which make your life easier. but i noticed that expressjs does a lot less "holding hands" compared to .net core (c#), or laravel (php). can be a pro or a con.

As a developer myself, I would recommend you not to restrict yourself to JAVA, PHP or any other language. New Tools/languages keep coming every day. If you do plan to move to freelancing. PHP has a lot of options in the freelance space and a lot of competition too.

Learning PHP is as simple as learning any other language. It depends merely on your interest.

Personally if you can code, you should not restrict yourself. I have had to code in many languages, PHP, Perl, shell script, Python, Java, Javascript, Ruby etc... I would keep your developing skills and logic, algorithms etc.. and increase your knowledge and experience in the different languages.

I agree with you JAVA is a lot more time consuming. But it also has its enterprise level scope.

At the same time learning a new language should not be a barrier for you to stop exploring what's out there and keeping your skills up to date. Learning new technologies should be your primary focus and getting project out of your stack helps you build a good reputation.

There are many options for you to pursue. Having an open mindset will help you move forward. If you look to learn now, you are setting yourself up for a brighter future.

I am currently planning to build a project from scratch. I will be using Angular as front-end framework, but for the back-end I am not sure which framework to use between Spring Boot and NestJS. I have worked with Spring Boot before, but my new project contains a lot of I/O operations, in fact it will show a daily report. I thought about the new Spring Web Reactive Framework but given the idea that Node.js is the most popular on handling non blocking I/O I am planning to start learning NestJS since it is based on Angular philosophy and TypeScript which I am familiar with. Looking forward to hear from you dear Community.

NestJS is an excellent framework (they both are). I would say the fact that you're working with Angular makes NestJS a great match, unless you're splitting front and back end between developers. But even in that case I would still go with NestJS for a new project.

Regarding the single threading point, take a look at PM2 which helps to run Node in multiple processes (we use it with NestJS) https://pm2.keymetrics.io/docs/usage/cluster-mode/

Also regarding web server performance in general this is an interesting post showing how Node with outperform Java in a web situation (be careful though, best to check a few posts to make sure these aren't totally biased benchmarks!): https://www.tandemseven.com/blog/performance-java-vs-node/

Node.js has only 1 real thread per process; Java JIT will mostly run faster than JS one; So if it happens to be not only I/O... Why do you need most popular, not simply popular? Does Node.js have tech advantages?

For context, I currently use JavaScript (React) and Python (Flask) in my daily routine.

I need your help in choosing either Spring Boot or ASP.NET Core. Both frameworks seem to have mature ecosystems. I would like to hear your thoughts on the following points:

  • Difficulty level of both frameworks
  • Level of community support
  • Career prospects i.e do Spring based jobs pay more or vice versa
  • which one will be helpful if I decide to transition towards a more specialized field like data engineering.

I am asking this because it is something that I am also exploring in parallel. I know that Python and #SQL play a huge role in big data.

I'll preface this by saying I haven't ever done work on the Microsoft stack, so take this with a grain of salt.

Community support: Java tends to have a more active community (and much more diverse universe of new open source projects) than .Net (related to below).

Difficulty level: I'd say the Java/Spring stack is more difficult because Java developers tend to use more community projects and have to know which ones to choose in which circumstances (e.g. what logging framework to use? What database connection pooling library to use? What testing framework to use). That being said, most decisions you have to make have choices that are vastly more popular than others. My impression is that .NET guys use stuff from the standard library almost exclusively. If it's not provided there, it's a problem they never thought to solve or maybe write their own (usually the former).

Career prospects: I'll get hate for this probably, but Java/Spring has more jobs than .Net. .NET Core even more so because it's new. Most .NET jobs out there are going to be not Core, and not on anything other than Windows. LinkedIn search for jobs in United States shows 97,103 for Java and 36,448 for C#. That's not to say some individual city might not have more .NET than Java, but by and large Java is bigger. Also, .NET is not dying at the same pace as say Ruby on Rails (sorry Rails fans). I'd say it's ticking very slowly lower, maybe even holding steady. I wouldn't say you're screwed career-wise if you choose .NET. C# is also pretty similar to Java from what I've seen, and I know professionals that have transitioned to Java (though interestingly, I don't know any that did the reverse). Several companies have basically no .NET footprint, for example, Amazon, Google, Facebook, LinkedIn, Twitter all have Java, but basically no C#.

Specialized fields: Neither Spring or .Net are going to be a thing in a field like data science. That's exclusively Python (some R) for the most part. The only exception being that there is some Java in Hadoop, and Scala in Spark (which runs on the JVM). But I think those are generally more for data products being created, and not data science work. I'm also under the impression this is increasingly less the case than historically. Some other specialties might make Java useful, for example Android development.

In short, Java is the COBOL of the modern enterprise (which is both a good and bad thing). I recommend it to anyone over .NET, but not for technical reasons. It's for reasons related to the questions you asked. There are actually reasons I think CLR and C# are actually better from a technical perspective than Java (unsurprisingly, since they had the benefit of hindsight). But that's not what you were asking about...

Spring boot helps you creating microservices in hours, not days and there is a very active community around it with amazing integrations. Check one of the tutorials maybe. At least here in Germany, the job market will be better for Spring Boot as well, there are a lot more companies using Java then C#.

ASP.NET Core is pretty new while spring boot is very old but with a different name. Spring boot is just a pack of spring packages which make your life easier. I also believe that java community is way stronger than c# community... You can do your job in both frameworks and it's up to you what you choose after-all you're going to work on the project/lead it ... but whatever you choose.. after a few days of investment stick with your decision because in both frameworks you'll encounter challenges :)

I鈥檒l echo what others have said here with a few twists.

I have experience with both platforms including Micronaut, a relatively new kid on the block. It all depends on your near term goal. If it is to make money, sure Java jobs pay more generally because there is more hassles when dealing with the entire ecosystem. Like someone said earlier, you have to make a decision at almost every stage of the development cycle from the IDE, dependency resolution framework, logging, serialization, microservice framework etc. There is just too much choice which some may argue is an advantage while others may argue is a distraction and productivity killer. At the end of the day you can build solid systems with both frameworks.

Coming to ASP Core, yes I also agree that options are more streamlined. You鈥檒l be using Visual Studio or Visual Studio code. For dependency management, you鈥檒l be using Nuget. But I disagree with one of the comments above about the lack of choice. In some aspects .NET actually has more choice believe it or not for example choice of ORM. There is entity framework, nhibernate, dapper etc. For J2ee, hibernate reigns supreme although you have JPA. For dependency injection you have many IoC containers like unity, castle Windsor in .NET while you have Guice and maybe a Spring based implementation.

Also C# is technically a better language that Java. That鈥檚 not questionable as has also been stated above. Many things are done right obviously by avoiding some of the mistakes made in the underlying architecture surrounding the Java programming language. That鈥檚 why Microsoft created c# to begin with. The language is a lot cleaner and allows you to focus on learning core principles and nail down fundamental OO with emphasis on good design. I find too many distractions in the Java ecosystem which takes me away from understanding the core problem I am trying to solve.

So as you can this is not an easy decision and as someone has stated there鈥檚 work to do regardless of what technology choice you make.

If your sole purpose is to make a higher base salary, sure pick Spring Boot. If you want to quickly deliver something and iterate, pick ASP Core. I personally use c# for all private projects and proving concepts even though my employer is a Java shop. It allows me to stay focused on solving the problem and not constantly wrestle with issues such as Gradle dependency resolution glitches in IntelliJ.

Given that you can transfer skills from .NET to J2ee I recommend guys to pick up ASP get a couple of services to get a feel web development as you can still get jobs in Java even with that experience. Companies don鈥檛 care these days. In fact a lot of companies are going to Go so there鈥檚 that too.

Depends on your immediate term goal.

Both of them are equally good for me, long term perspective most of services will be more based on I/O vs heavy computing. Leaning toward node.js, but will require team to learn this tech stack, so little hesitant.

It's probably worth investing some time for your team to learn Node.js. There's very little overhead, especially with a framework like ExpressJS, so if your team is familiar with JavaScript it should be a quick process.

It handles I/O really well out of the box, and has a strong community with great open source libraries. Since you're using React on the front end, there's also some benefit to being able to use JavaScript throughout your stack.

It's a general development question, be more specific, because /dev/std... is a generic approach, not a targeted development. You want to develop PHP or Java? Both are good in their terms, but it's your decision. For PHP Laravel is a robust and exhaustive console enabled framework, featuring rich integrations with virtualization & REST. On the other hand, Spring will bring you learning curve if you are switching from PHP and so on. Try to match your needs with project requirements, it will be easier.

Laravel is lighter weight. Spring Boot quickly becomes a handful, as you'll be downloading hundreds of megabytes in dependencies for a few functions and a dynamic dependency there. There are multiple problems that are solved by "download and put it on your classpath by whatever means. Spring framework will automatically detect it and resolve the issue". It's magical when things work, but my teams have constantly found the limits of the framework's utility and starting points of their burden.

While my expertise with Laravel is more limited, I haven't seen this kind of mess in that community and God bless 'em for it.

What is Spring Boot?

Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.

What is Vert.x?

It is event driven and non blocking application framework. This means your app can handle a lot of concurrency using a small number of kernel threads. It lets your app scale with minimal hardware.
