Webpack unable to find browser-sync-webpack-plugin unless browser-sync package is installed.

[nparoski]

Hello, I was creating custom webpack config and installed browser-sync-webpack-plugin It wouldn't work at all until I installed browser-sync as dev dependecy on my project. Can anyone provide explanation? What did I misunderstand and why is browser-sync not a dependecy of browser-sync-webpack-plugin?

webpack.config.js

/// <binding />
"use strict";
var path = require("path");
var WebpackNotifierPlugin = require("webpack-notifier");
var BrowserSyncPlugin = require("browser-sync-webpack-plugin");

module.exports = {
  entry: ["babel-polyfill", "./React/src/index.js"],
  output: {
    path: path.resolve(__dirname, "./React/dist"),
    filename: "bundle.js",
  },
  module: {
    rules: [
      {
        test: /\.jsx?$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader",
        },
      },
      // Handles style loading
      {
        test: /\.s[ac]ss$/i,
        use: [
          // Creates `style` nodes from JS strings
          "style-loader",
          // Translates CSS into CommonJS
          "css-loader",
          // Compiles Sass to CSS
          "sass-loader",
        ],
      },
      {
        test: /\.css$/i,
        use: ["style-loader", "css-loader"],
      },
    ],
  },
  devtool: "inline-source-map",
  plugins: [new WebpackNotifierPlugin(), new BrowserSyncPlugin()],
  resolve: {
    extensions: [".js", ".jsx"],
  },
};
