Helper module for loading your native module's
This is a helper module for authors of Node.js native addon modules.
It is basically the "swiss army knife" of
require()ing your native module's
Throughout the course of Node's native addon history, addons have ended up being
compiled in a variety of different places, depending on which build tool and which
version of node was used. To make matters worse, now the
gyp build tool can
produce either a Release or Debug build, each being built into different
This module checks all the possible locations that a native addon would be built at, and returns the first one that loads successfully.
$ npm install --save bindings
Or add it to the
"dependencies" section of your
require()ing the proper bindings file for the current node version, platform
and architecture is as simple as:
var bindings = require('bindings')('binding.node') // Use your bindings defined in your C files bindings.your_c_function()
Nice Error Output
.node file could not be loaded,
node-bindings throws an Error with
a nice error message telling you exactly what was tried. You can also check the
err.tries Array property.

The searching for the
.node file will originate from the first directory in which has a
