A simple loader to embed native addons in [node] or [electron] projects.

This package is a mix between:

- [node-loader] that loads a node module from an _absolute path_

- [file-loader] that loads copy a file into the bundle and return its path

This one package allows to load a node native addon, binary file will end up copied into the output directory and loaded dynamically from its _relative_ path.

## Install

Add the package to your `package.json`

```bash

$ yarn add --dev node-addon-loader

```

## Usage

Add the loader to your `webpack.config.js` for all `.node` native files.

**webpack.config.js**

```js

module.exports = {

  module: {

    rules: [

      {

        test: /\.node$/,

        use: 'node-addon-loader',

        options: [

          basePath: resolve(__dirname),

        ]

      }

    ]

  }

}

```

Note the `basePath` option: it will instruct the loader of the "base" path, from where the [node] runtime will be started. It will generate loading path relative to this URL.

For example is you develop an [electron] app with a bundle emitted into `dist/` directory, you want all the required paths (emitted `require` statements) to be relative to the current directory of the [electron] runtime (they all will be like `dist/xxxx.node`).

**In your application**

You require the file directly

```js

import node from 'relative/path/to/myLib.node';

// or

const node = require("relative/path/to/myLib.node");

```

or with the inline syntax:

**Inline**

```js

import node from 'node-addon-loader!./myLib.node';

```

**with an alias**

a good option is to keep your modules in some place and create aliases for them, such as:

```js

// webpack config

module.exports = {

  resolve: {

    alias: {

    "myLib": "/path/to/myLib.node",

    }

  },

  // ...

}

```

and then use your alias directly:

```js

import myLib from "myLib";

```

## Thanks

big thanks go the the authors of [node-loader] and [file-loader] which I eagerly copied.

## TODO

Fix the issue with `emitFile`, see **TODO** in code.
