Javet

Maven Central Discord Donate

Linux Build Android Build

Javet is Java + V8 (JAVa + V + EighT). It is an awesome way of embedding Node.js and V8 in Java.

If you like my work, please Star this project. And, you may follow me @sjtucaocao, or visit http://caoccao.blogspot.com/. And the official support channel is at discord.

If you use Mac OS (x86_64), please be aware that the Mac OS (x86_64) build will discontinue anytime because my MacBook Air mid-2012 will be soon deprecated by new version of V8. Please donate to support me purchasing a new Mac OS (x86_64) device. Or, if you have a retired Mac OS (x86_64) device and are fine with mailing it to me, that will also be great. Thank you for supporting Javet.

If you use Mac OS (arm64), please thank @longwa for building the M1 version. However, that's a temporary solution because I don't have any Mac OS (arm64) device, so there is no support. Please donate to support me purchasing a new Mac OS (arm64) device.

Major Features

  • Linux (x86_64) + Mac OS (x86_64, arm64) + Windows (x86_64)
  • Android (arm, arm64, x86 and x86_64)
  • Node.js v16.13.1 + V8 v9.7.106.18
  • Dynamic switch between Node.js and V8 mode (Which mode do you prefer?)
  • Polyfill V8 mode with Javenode
  • V8 API exposure in JVM
  • JavaScript and Java interop
  • Native BigInt and Date
  • Javet engine pool
  • Easy spring integration
  • Live debug with Chrome DevTools
