jsni is the interface for JavaScript and C/C++, which is vm neutral and keeps abi/api compatible.

So the developers can avoid rewriting their native modules once v8/nan or other vms api changes.

It is acronym for JavaScript Native Interface.

Prerequisites:

• node 7.x or above
• npm

We can try jsni beginning with the hello-world example.

First, clone it to your local machine.

git clone https://github.com/alibaba/jsni.git -b example 

Second, install jsni using npm:

cd jsni/hello-world/ npm install jsni 

Finnally we can build and run it:

node-gyp rebuild node test.js 

And it will show "hello".

The essential JavaScript code is like this:

var jsni = require("jsni"); var addon = nativeLoad("addon"); console.log(addon.hello());
