Javenode is Java + V8 + Node.js. It is a Node.js simulator with Java in V8.
Javenode is an extension of Javet <https://github.com/caoccao/Javet>
_ (Java + V8). It aims at simulating Node.js with Java in Javet V8 mode. Why? Because Javet V8 mode is much more secure than the Node.js mode, but lacks of some basic features, e.g. setTimeout
, setInterval
, etc. So, these must-have API can be found in Javenode.
