To set up for development, you'll install webpack-dev-server. Instead of building to a dist file, the development mode will just run everything in memory. a development config, that runs webpack in a server, updates with every change, and has source maps.a production config, that minifies, optimizes and removes all source maps.You'll want to set up two configurations for webpack: The bigger your site gets, the longer it will take to build.

Alternatively, if you are using npm v5.2.0 or greater, you can run npx webpack to do it. Var webpackIsomorphicToolsPlugin = new WebpackIsomorphicToolsPlugin(require('./webpack-isomorphic-tools')) To run the local installation of webpack you can access its binary version as nodemodules/.bin/webpack. Var WebpackIsomorphicToolsPlugin = require('webpack-isomorphic-tools/plugin') Then, depending on this graph, it creates a new package which consists of the very bare minimum. Its main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset. Var assetsPath = path.resolve(_dirname, './static/dist') So how was Webpack the answer In brief, Webpack goes through your package and creates what it calls a dependency graph which consists of various modules which your webapp would require to function as expected. Var WebpackIsomorphicTools = require('webpack-isomorphic-tools')
