Server side rendering React in Java Springboot

Question

I'm new to server side rendering & I want to render React components on server side and pass down it in html.

I followed this tutorial on https://spring.io/guides/tutorials/react-and-spring-data-rest/. It is still rendering on client.

I cannot find a way to do renderToString in the thymeleaf template.

How do I do this?

Answer 1

Using Nashorn you can do, Nashorn is a JavaScript engine packaged by default with Java.

Nashorn has been released as part of Java 8. This is primarily focused on allowing embedded JavaScript applications in Java.

Nashorn compiles JavaScript in-memory to Java Bytecode and passes it to the JVM for execution.

And more details you can check below link:-

Nashorn is deprecated now, so you can use GraalVM for this
