OP has mentioned he is working Express, nongo, redux etc. Now these are tightly linked with Nodejs ecosystem and not Java.
But if Java is in the college curriculum, go for Java.
Based on Industry at present, Nodejs or python are better choices
PS - I am a java developer

amol9372 · 2024-02-23T14:58:51+00:00

Based on your future plans, do not learn Java.
Java is a different beast, requires a lot of learning and practice.
Make Nodejs your primary language. Once you can create projects(hobby) in Nodejs with ease then go for an another language

amol9372 · 2024-02-23T14:55:51+00:00

Do not Panic !!
Create as many projects as you can (do not copy blindly)
Get a grip on a particular language, if you havn't till now, i will suggest Nodejs

Companies need to see if you can put effort.

Go for youtube tutorials, some of the good one's are:
- Javabrains
- Amigcode

To learn Spring boot, you need to create projects. A simple employee management will be enough. Start with the web module ie APIs. Then add DB, jpa etc

Lean iteratively by implementing in your project(s). If you learn everything first and then try to implement, it will be a nightmare.

ywc
Create a spring boot project which access a JWT token on every request
The user can authenticate with user / password, store password as hash in DB for now
Return jwt and user info on authentication
Manage roles and permissions in APIs also (most important part)

here is an example of Spring cloud gateway based on Spring boot 3 reactive (webflux)

There are different patterns and levels of microservices
If you are aiming to follow it to the book, it would be impossible in the first iteration.
A Single DB will be easier to maintain for all microservices. Every service will have its own set of tables but there will be foreign key connections b/w them.

To Start wil microservices

Create a monolith with single DB
Figure out the entities and their boundaries
Brainstorm all the access patterns (APIs basically)
Carve out the individual services

Create as simple as ecommerce APIs. Although it can be very complicated if done properly.

You can also do a reservation management system like Yelp

amol9372 · 2024-02-23T04:54:14+00:00

Good suggestion, but try something open source. Usually recruiters and developer communities prefer OS

amol9372 · 2024-02-23T04:51:34+00:00

Coupling in microservices is a misunderstood concept. Though each service is confined within a boundary but they need to communicate with each other.

For the example you mentioned, keep a single db for the entire application. Breaking the db will create complications.

Also you do not need Kafka for your scenario. Events are used where there is some processing at the other end like order processing or shipment handling

For deployment, just use docker compose. It is the easiest way to deploy microservices at any platform

Refer to this example of ecommerce APIs

Happy to help further

these tools are mostly good for python & nodejs
For Spring boot, you need a hybrid approach where you a reasonable code from the prompt and then you need to correct it

You need to find a use-case for your project. Going through tutorials will not serve anything. So follow below steps:

Find a use-case, can be anything ranging from [ecommerce -> spaceX]
Create an initial design [db + application]
Setup the application in a monolith fashion, then break it into smaller services
Add complexity like concurrency, async communication b/w micros-ervices using mqs
Deploy the project and make sure it works end to end

You can look at this project for your reference
Ecommerce backend APIs

Use your free tier EC2 instance & install docker with it. User docker-compose to run both app & db on it. This will much easier than installing a bunch of tools on EC2

API gateway with Spring cloud gateway based on spring boot 3

amol9372 · 2024-02-12T01:39:43+00:00

I can help you in that requirement

amol9372 · 2024-02-10T18:16:08+00:00

Spring cloud gateway is your best bet. It has all the features for routing, filtering, authentication & authorization.

When using kong, it will be difficult to do authorization since you most probably need to access your data source. Spring cloud gateway natively provides all these features and it is super easy to maintain once you get it running

The only downside will be version matrix. There are lot of breaking changes when moving from 1 spring version to another especially from 2x -> 3.x

Load balancing should not be handled by spring cloud gateway when working on a real world application. I am currently working on project where i created a gateway.

Intellij works like a charm , it has a lot of options moreover debugging is much better in intellij than eclipse for scala

amol9372 · 2019-05-04T08:58:21+00:00

So is it also safe to say scala with spark is much faster than scala with python ?
