| 3 | ### Helper module for loading your native module's `.node` file
|
|---|
| 4 |
|
|---|
| 5 | This is a helper module for authors of Node.js native addon modules.
|
|---|
| 6 | It is basically the "swiss army knife" of `require()`ing your native module's
|
|---|
| 7 | `.node` file.
|
|---|
| 8 |
|
|---|
| 9 | Throughout the course of Node's native addon history, addons have ended up being
|
|---|
| 10 | compiled in a variety of different places, depending on which build tool and which
|
|---|
| 11 | version of node was used. To make matters worse, now the `gyp` build tool can
|
|---|
| 12 | produce either a __Release__ or __Debug__ build, each being built into different
|
|---|
| 13 | locations.
|
|---|
| 14 |
|
|---|
| 15 | This module checks _all_ the possible locations that a native addon would be built
|
|---|
| 16 | at, and returns the first one that loads successfully.

| 19 | Installation
|
|---|
| 20 | ------------
|
|---|
| 21 |
|
|---|
| 22 | Install with `npm`:
|
|---|
| 23 |
|
|---|
| 24 | ``` bash
|
|---|
| 25 | $ npm install --save bindings
|
|---|
| 26 | ```
|
|---|
| 27 |
|
|---|
| 28 | Or add it to the `"dependencies"` section of your `package.json` file.
|
|---|
| 29 |
|
|---|
| 30 |
|
|---|
| 31 | Example
|
|---|
| 32 | -------
|
|---|
| 33 |
|
|---|
| 34 | `require()`ing the proper bindings file for the current node version, platform
|
|---|
| 35 | and architecture is as simple as:
|
|---|
| 36 |
|
|---|
| 37 | ``` js
|
|---|
| 38 | var bindings = require('bindings')('binding.node')
|
|---|
| 39 |
|
|---|
| 40 | // Use your bindings defined in your C files
|
|---|
| 41 | bindings.your_c_function()
|
|---|
| 42 | ```
|
|---|
| 43 |
|
|---|
| 44 |
|
|---|
| 45 | Nice Error Output
|
|---|
| 46 | -----------------
|
|---|
| 47 |
|
|---|
| 48 | When the `.node` file could not be loaded, `node-bindings` throws an Error with
|
|---|
| 49 | a nice error message telling you exactly what was tried. You can also check the
|
|---|
| 50 | `err.tries` Array property.
|
|---|
| 51 |
|
|---|
| 52 | ```
|
|---|
| 53 | Error: Could not load the bindings file. Tried:

|---|
| 70 | ```
|
|---|
| 71 |
|
|---|
| 72 | The searching for the `.node` file will originate from the first directory in which has a `package.json` file is found.
