node-loader

A Node.js add-ons loader.

Allows to connect native node modules with .node extension.

> ⚠ node-loader only works on the node/async-node/electron-main/electron-renderer/electron-preload targets.

Getting Started

To begin, you'll need to install node-loader:

``console
$ npm install node-loader --save-dev
`

Setup the target option to node/async-node/electron-main/electron-renderer/electron-preload value and do not mock the __dirname global variable.

webpack.config.js

`js
module.exports = {
target: "node",
node: {
__dirname: false,
},
module: {
rules: [
{
test: /\.node$/,
loader: "node-loader",
},
],
},
};
`

$3

index.js

`js
import node from "node-loader!./file.node";
`

And run webpack via your preferred method.

$3

index.js

`js
import node from "file.node";
`

Then add the loader to your webpack config. For example:

webpack.config.js

`js
module.exports = {
target: "node",
node: {
__dirname: false,
},
module: {
rules: [
{
test: /\.node$/,
loader: "node-loader",
},
],
},
};
`

And run webpack via your preferred method.

$3

Type: Number

The flags argument is an integer that allows to specify dlopen behavior.
See the process.dlopen documentation for details.

index.js

`js
import node from "file.node";
`

webpack.config.js

`js
const os = require("os");

module.exports = {
target: "node",
node: {
__dirname: false,
},
module: {
rules: [
{
test: /\.node$/,
loader: "node-loader",
options: {
flags: os.constants.dlopen.RTLD_NOW,
},
},
],
},
};
`

$3

Type: String|Function
Default: '[contenthash].[ext]'

Specifies a custom filename template for the target file(s).

{
test: /\.node$/,
loader: "node-loader",
options: {
name: "[path][name].[ext]",
},
},
],
},
};
`

#### Function

webpack.config.js

`js
module.exports = {
target: "node",
node: {
__dirname: false,
},
module: {
rules: [
{
test: /\.node$/,
loader: "node-loader",
options: {
name(resourcePath, resourceQuery) {
// resourcePath - /absolute/path/to/file.js
// resourceQuery - ?foo=bar

if (process.env.NODE_ENV === "development") {
return "[path][name].[ext]";
}

return "[contenthash].[ext]";
