How to reuse application constants written inside Java classes within javascript?

Question

Is there is a way to reuse public static final constants defined inside Java classes with the javascript files ?

Or is there a better way to define such constants so that they can be reused by both java & JavaScript ?

Answer 1

A very simple solution would be to store your config as JSON on the server side, then have the server inject that into the HTML response to the client.

The server can read the JSON on startup and keep it in a singleton object.
