构建现代 webApp

Question

I hope you are doing well.

I have a fundermental question to the experienced developers here. I am planning to build a microservice web-application with java spring backend and react frontend. I am experienced with java and I am learning react at the moment. I plan to host my application on my rancher single node cluster.

I have a few questions to some points I havent figured out yet(sry Im a newbee)

1. How should I manage the user-login system? I have already done some web-development and built a login-sys with php for example but I have no idea what to use for a microservice-application with spring and react. I mean every applaction needs a login system, is ther maybe already a "plug and play solution"?

2. Do you have some tips how to setup a database infrastructure for the project?

3. I want to start with the application as fast as possible. It does not need to be perfect. I just want to have a platform to test and collect some experience. What you think about the combination of sprint/react/rancher? Does anybody know a good guide to build an application like this?

I would be very happy if somebody can help me. Thank you for your answers and have a nice day. :)

Best Mamo

I can recommend keycloak open source IAM for authentication and authorization. In order to configure it:

• front end you can use react-auth-config library
• backend you can use Spring Security You can check this post for Spring Boot and Keycloak:

This will give you token based authentication For database, it is up to your entity relations. First you need to decide whether you need a relational one or not. Then you can consider several options You can check this post
