# ndarray Native Add-ons > C APIs for creating Node-API ndarray native add-ons.
This package exposes an absolute file path for the directory containing header files for various C APIs. The various C APIs facilitate the creation of Node-API ndarray native add-ons.
## Usage ```javascript var headerDir = require( '@stdlib/ndarray/base/napi' ); ``` #### headerDir Absolute file path for the directory containing header files for C APIs. ```javascript var dir = headerDir; // returns ```
## Examples ```javascript var headerDir = require( '@stdlib/ndarray/base/napi' ); console.log( headerDir ); // => ```
