node-polyfill-webpack-plugin

Polyfill Node.js core modules in Webpack.

This module is only needed for Webpack 5+.

Install

``sh
npm install node-polyfill-webpack-plugin
`

Usage

Add the following to your webpack.config.js:

`js
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin');

module.exports = {
// Other rules...
plugins: [
new NodePolyfillPlugin(),
],
};
`

console, process, and most deprecated/internal Node.js core modules are not polyfilled by default. If you still need to polyfill them, you can use the additionalAliases option:

`js
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin');

module.exports = {
// Other rules...
plugins: [
new NodePolyfillPlugin({
additionalAliases: ['process', 'punycode'],
}),
],
};
`

The fs module resolves to nothing because its functionality cannot replicated in the browser.

#### options

Type: object

onlyAliases is mutually exclusive with excludeAliases and additionalAliases.

#### excludeAliases

If you don't want a module to be polyfilled, you can specify aliases to be skipped here.

`js
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin');

module.exports = {
// Other rules...
plugins: [
new NodePolyfillPlugin({
excludeAliases: ['console'],
}),
],
};
`

#### additionalAliases

Alternatively, you can choose to add certain aliases to the list of polyfilled modules. For example, you can choose to polyfill console.

`js
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin');

module.exports = {
// Other rules...
plugins: [
new NodePolyfillPlugin({
additionalAliases: ['console'],
}),
],
};
`

#### onlyAliases

You can also choose to only include certain aliases, ignoring the defaults. For example, you can have only console polyfilled.

`js
const NodePolyfillPlugin = require('node-polyfill-webpack-plugin');

module.exports = {
// Other rules...
plugins: [
new NodePolyfillPlugin({
onlyAliases: ['console'],
}),
],
};
`
