Spring Boot

As a Laravel developer, I'd have to say go with Laravel. Although you can move away from PHP, it means any of that legacy code will still need to be completely ported to Java or whatever other language you use. Whereas, staying with PHP, you may find it easier to re-use/adapt that existing code.

Of course, if you're going for a full rewrite, then that might not be a useful consideration. However, even a full rewrite will introduce a lot of changes. When having to do this kind of thing, I recommend changing as few things as possible at once. So staying in the same language while upgrading may keep some pain points down.

Vue.js with PHP/Laravel (vue.js is much better than Angular for building the frontend. I feel much cleaner and faster). you already using MySQL database PHP is prefered.

Job search can be hard and pretty daunting.

However, I recommend you sticking with whatever you have the most experience with. MERN stack and Spring Boot jobs are actually very high in demand in service based companies, a lot of which can allow you to work remotely if their specific clients work at hours that don't match with yours.

I recommend going over on LinkedIn itself and search for Associate/Junior dev positions with Java or JavaScript filters rather than specific Nodejs or Spring Boot filters. Freshers aren't generally expected to know web frameworks right after graduation, and undergo mandatory training anyways, even for vastly differing domains (you could undergo training for Go even though you mentioned skill in Java, as a fresher).

However, freshers are expected to know atleast 1 object oriented language, in which they can demonstrate fundaments of OOP, basic logic building, and working with Strings. It starts with senior roles in software industry where people are generally asked about what "stack" they previously worked on, which influences decision making for hiring people.

As a fresher, you are expected to know nothing. So start filtering and applying that you know nothing and want to learn everything, while job searching. Good Luck!

You should really try NodeJS with ExpressJS

I would recommend sticking to what you have already spent your time on.

You are in your final year, you spent a great deal of time and effort on Java. The Java has a larger marketplace in your area according to you. So, it would be logical for you to go with it unless you have lost your interest.

I would also like to give the same advice, stick to your current stack. You would start learning other stacks gradully. Don't shift yourself right now.

I don't think it matters

front-end : React is really cool and I enjoy it but you can build a website with Angular and Vue, or even Svelte (I've never tried it), but these are all options.

back-end : Spring Boot Because the framework is so powerful, you could do this with NodeJS, which would be easier than Spring Boot, but you'd have to figure out your syntax preferences and ask other people if your stack is viable.

Django can be used, but Spring Boot is far more powerful in terms of scalability and security.

if no back-end needed : you can use NextJS to fetch your API calls and create a lightweight website.

I mean, your question is difficult to answer because we don't know the architecture you imagine for this project. you need to think about all the components you'll create end-to-end and write it down in a paper without considering the stack you'll use, and then you can ask again with more precision.

Given Angular is written in TypeScript, C# will feel more familiar to you. Other reasons to choose ASP.NET are that it's one of the fastest frameworks out there for any language, has a lower learning curve compared to Spring Boot, allows you to quickly build JSON Web APIs and uses less memory. Another notable option if you have a lot of TypeScript code you wish to reuse is Nest framework, which is a TypeScript framework that uses the same architecture as Angular but for back end APIs. I would still choose ASP.NET over Nest but it depends on what will give you more benefits.

Given you have cross platform experience (dart, angular) I would recommend spring boot. It is a powerful platform, allows you to easily integrate with many standard tools: databases, message queues, … And you have the freedom to deploy your applications on every platform that has Java or containers available - so virtually everywhere.

Both Python and Node.JS solves similar yet different purposes for microservices. As a concern, I choose Node.JS over anything as My services could be handled by any cloud. If you want to perform some tasks requiring more to the server, then definitely go for Python else JS is best.

I would go with Go if you need performance or solve highly concurrent tasks. If not, Node feels easier to work with and is arguably more common (also, it's JS - it's everywhere, and you can switch to FE more quickly since you want to focus on web apps). Python is cool as well, but I hate how the package management is not solved, and the pythonic coding standards are not excellent, in my opinion, of course. As for stability (in terms of their APIs), I guess Go is the safest choice (it's still v1, after all), Python is a close second, and Node changes relatively fast. It's also a question of what language(s) you already know and use.

I'd recommend to learn Spring as it is very widespread in the industry and provides a lot of easy integration into most of the common backend tech stacks. Rather than learning Java you could look into Kotlin. It's a very consistent, stable and well-thought language in my opinion and not as verbose as Java. Many problems can be solved with Kotlin in a clear and elegant way while also always having the option to use data structures and libs in JVM. It is also has a very good support in Spring.

Why not pick Django or Flask (both Python)

PrimeFaces is best combined with Jakarta EE. You could use for instance GlassFish or WildFly.

PrimeFaces uses Faces, and Faces uses CDI, which are both available by default in Jakarta EE. It's possible, but not super natural or trivial to add these to Spring Boot.
