@stdlib/napi-export

About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Node-API Exports

C utilities for registering Node-API modules.

Installation

npm install @stdlib/napi-export

Usage

var headerDir = require( '@stdlib/napi-export' );

headerDir

Absolute file path for the directory containing header files for C APIs.

var dir = headerDir;
// returns <string>

Examples

var headerDir = require( '@stdlib/napi-export' );

console.log( headerDir );
// => <string>

C APIs

Usage

#include "stdlib/napi/export.h"

STDLIB_NAPI_MODULE_EXPORT_FCN( name )

Macro for registering a Node-API module which exports a function.

#include <node_api.h>

// ...

static napi_value addon( napi_env env, napi_callback_info info ) {
    // ...
}

// ...

// Register a Node-API module:
STDLIB_NAPI_MODULE_EXPORT_FCN( addon )

The macro expects the following arguments:

• name: name of the C function to export.

When used, this macro should be used instead of NAPI_MODULE. The macro includes NAPI_MODULE, thus ensuring Node-API module registration.

STDLIB_NAPI_MODULE_EXPORT_FCN_WITH_METHOD( fcn_name, prop_name, fcn_method_name )

Macro for registering a Node-API module which exports a function having a method.

#include <node_api.h>

// ...

static napi_value addon( napi_env env, napi_callback_info info ) {
    // ...
}

static napi_value addon_method( napi_env env, napi_callback_info info ) {
    // ...
}

// ...

// Register a Node-API module:
STDLIB_NAPI_MODULE_EXPORT_FCN_WITH_METHOD( addon, "foo", addon_method )

The macro expects the following arguments:

• fcn_name: name of the C function to export.
• prop_name: property name.
• fcn_method_name: name of the C function to export as a method.

When used, this macro should be used instead of NAPI_MODULE. The macro includes NAPI_MODULE, thus ensuring Node-API module registration.

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
