在Javascript中使用Java库

Question

I am planning a project where I will develop bots for Agar.io by using the NEAT algorithm, which is implemented in Java (this is called ANJI ). I will use the open-source Agar.io server called Ogar , which is implemented in Javascript. The Javascript implementation should communicate with the Java library to evolve the bots while the game is running, but I have no previous experience of how to make Java and Javascript communicate. I have considered using Rhino, but it does not seem like it is possible to use in a browser. So, are there any way to let a Javascript implementation like Ogar use a Java library?

Answer 1

In common, Javascript and Java library communicate using Rest and Json, Java provide Rest API and Javascript send Json request to this API.

This is list of java library: for developing Java Rest API and working with JSON . I recommend using RESTEasy .

Answer 2

using the Rhino / Nashorm is not relevant in this case and as for performance focus its should be much hard to run nodeJS based application via Java JS engine.

the Agar.io server is a NodeJS server that expose a WebSocket API and the client solution need to communicate this way.

Using spring websocket client for example

have you seen Agar.io-bot ? its seems like the way they implement the BOT is javascript browser extension and communicate via the browser.
