C based minimal Node.js native addon example

An example of a Node.js native addon using C.

No extra tools other than node and a C compiler on $PATH needed for build. node-gyp that ships with node (via npm that ships with node) is used to install node headers.

If you are on windows, you can write a build.bat based off of the Makefile yourself.

To build and run the addon —

npm run build && npm test
# Should print Hello from addon!
# No npm install necessary either btw.

And as always with JS, there's noise to ask kindly to stfu. If npm is yelling about updates, run npm config set update-notifier false to shut it up.

• .node extension is necessary for node to actually load the addon
