PROBLEM?

The Proposal: Concern Separa:on

Build Pipeline → WebpackTask Management → NPM

So…?

Webpack

What is Webpack?• Module bundler

• Supercharges require

• Anything is require-able

• TransformaQons are based on loaders

• Other tasks can be implemented as plugins

• Outputs assets in single or mulQple files

• Built-in hashing → Easy cache invalidaQons

Webpack Features

J S X J S ( E S 5 )babel-loader

S C S S C S Spostcss-loader

P N G B A S E 6 4file-loader

B U N D L E . J S

How does Webpack?

const path = require('path') const CopyPlugin = require('copy-webpack-plugin')

module.exports = { entry: "./index.js", output: { path: path.join(__dirname, 'dist'), filename: "bundle.js" }, module: { loaders: [ { test: /\.css$/, loader: "style!css" }, { test: /\.js$/, loader: "babel" }, { test: /\.(svg|ttf|otf|eot|woff|woff2|png|jpg|gif)$/, loader: "file" } ] }, plugins: [ new CopyPlugin([ { from: 'index.html' } ]), new Uglify([ { from: 'index.html' } ]) ] }

Just use NPM scripts

What are NPM scripts

• Custom commands through run-script

• Pre-hooks for custom commands

• Include package binary entry points

• Command composiQon

What are NPM scripts

npm install -g

npm run-script

npm run
