Webpack Configuration

Webpack configuration with following features:

• Hot Reloading in Development
• Production Optimized Build
• JSX and Vue
• Babel
• Eslint
• Sane Project Structure

How To Use

Install

Install this package

npm install sm-webpack-config --save-dev

NOTE: You need to install node-sass if you want to use sass, and compression-webpack-plugin if you want to use gzip option.

Programmatic Usage

const smWebpack = require('sm-webpack-config');

// Set Configuration [Optional]
const config = {
	sourcePath: 'res',
	destPath: 'static/dist',
	publicUrl: '/static/dist',
	sourceMap: true,
	devServerPort: 3001,
	appPort: 3000,
};

// Run Developement Server With Hot Reloading
smWebpack.runDevServer({config});

// Build For Production
smWebpack.runProdWebpack({config});

// If you want to go advanced and override some webpack configuration
const webpackConfig = {
	plugins: [
		new webpack.optimize.UglifyJsPlugin({
			compress: {
				warnings: true
			}
		}),
	],
};

// Run Developement Server With Hot Reloading
smWebpack.runDevServer({config, webpackConfig});

// Build For Production
smWebpack.runProdWebpack({config, webpackConfig});

// NOTE: Both config & webpackConfig are optional

CLI Usage

# Run devserver with default directory structure and ports assumed
sm-webpack serve

# Build for production with default 
sm-webpack build
# OR
sm-webpack

# Build for development
sm-webpack build --dev

# Specifiy source and destination
sm-webpack build --src res/project1 --dest static/dist/project1

# Specify different ports
sm-webpack serve --dev-port 3050

Using with config

Add a sm-webpack.js file to your project's root directory with the config for your project exported. Or add a "sm-webpack" key to your package.json.

Eg. sm-webpack.js:

module.exports = {
	sourcePath: 'res/project1',
	destPath: 'static/dist/project1',
	publicUrl: '/static/dist/project1',
	devServer: {
		port: 3001,
		appPort: 3000,
	},
};

# Start project's dev server
sm-webpack serve

# Build project for production
sm-webpack

Multiple projects

If you have multiple projects you can export an object with multiple confs and use the --config [keyName] option to select project.

Eg. sm-webpack.js:

module.exports = {
	project1: {
		sourcePath: 'res/project1',
		destPath: 'static/dist/project1',
		publicUrl: '/static/dist/project1',
		devServer: {
			port: 3001,
			appPort: 3000,
		},
	},
	project2: {
		sourcePath: 'res/project2',
		destPath: 'static/dist/project2',
		publicUrl: '/static/dist/project2',
		devServer: {
			port: 3002,
			appPort: 3000,
		},
	},
}

# Start project1's dev server
sm-webpack serve --config project1

# Build project2 for production
sm-webpack --config project2

Using with Gulp

You can also use it in gulp using the following gulpfile

const smWebpack = require('sm-webpack-config');
const gulp = require('gulp');

// The development server (the recommended option for development)
gulp.task('default', function(callback) {
	smWebpack.runDevServer().then(callback);
});

// Build files for production
gulp.task('build', function(callback) {
	smWebpack.runProdWebpack().then(callback);
});

Now you can use gulp to run dev-server and gulp build to build for production.

Default Project Structure

• Keep all your client side code in res

  • all javascript in js
    • vue components in components
    • 3rd party scripts in vendor (though they should generally be installed from npm)
  • css / scss in css
  • images in img
  • other assests in assests
    • eg. fonts can be kept in assests/fonts
  • directly served static assests in public
    • assests in this directory will not be compiled and copied directly to the public folder in dist
    • this directory should be used as public root directory in your server config
  • index.html as entry point (no need to include js/css, they will automatically be injected by webpack).

• all the compiled code will be put in static/dist

• point your static server to static directory

• use public path as /static

• api endpoints should start with /api

• Keep your server running at port 3000

• Dev server will run at port 3001

Webpack Aliases

The following aliases are defined

// by default config.sourcePath points to `res`, you can override it in your config
{
	'@': config.sourcePath,
	'res': config.sourcePath,
	'js': path.join(config.sourcePath, 'js'),
	'assets': path.join(config.sourcePath, 'assets'),
	'components': path.join(config.sourcePath, 'js', 'components'),
	'css': path.join(config.sourcePath, 'css'),
	'img': path.join(config.sourcePath, 'img'),
}

So you can write import Hello from 'components/Hello.vue' from anywhere If you want to use images in your vue templates use them as ~img/logo.png (append a ~) See https://github.com/vuejs/vue-loader/issues/193

SSR (Server Side Rendering)

sm-webpack-config includes support for Vue SSR. Everything should work if you set the config.ssr option. Building will give bundles for both server side and client side.

Default bundle file names are as given by vue. Server Bundle: vue-ssr-server-bundle.json Client Manifest: vue-ssr-client-manifest.json

You'll need to use createBundleRenderer from vue-server-renderer for SSR. For more details see Vue SSR docs

Running Dev Server With SSR

Running dev server with ssr support is a bit tricky. You'll need to use your own server and koa middleware provided by sm-webpack-config to set it up. koaDevServer fires a vue-ssr event with {serverBundle, clientManifest} as parameters whenever a new ssr bundle is ready.

Here's a quick example

const Koa = require('koa');
const {createBundleRenderer} = require('vue-server-renderer');
const {koaDevServer} = require('sm-webpack-config');

const app = new Koa();

const template = fs.readFileSync('./res/index.html', 'utf-8');
function createRenderer(bundle, clientManifest) {
	const options = {
		clientManifest,
		template,
		runInNewContext: false,
	};
	return createBundleRenderer(bundle, options);
}

const buildConfig = {
	// your build config
	entry: {
		app: 'js/index-client.js',
	},
	devServer: {
		port: 3002,
		appPort: 3000,
	},
	ssr: {
		entry: 'js/index-server.js',
		sourceMap: true,
	},
};

const devServer = koaDevServer({
	config: buildConfig,
});

let renderer;
// dev server fires vue ssr event whenever a new bundle is generated
// we replace the renderer each time it is fired (hot loading)
devServer.on('vue-ssr', ({serverBundle, clientManifest}) => {
	renderer = createRenderer(serverBundle, clientManifest);
});
const renderToString = (...args) => {
	if (!renderer) return 'Waiting to generate renderer...';
	return renderer.renderToString(...args);
};

app.use(devServer.middleware());
app.use(async (ctx, next) => {
	const ssrContext = {url: ctx.url};
	ctx.body = await renderToString(ssrContext);
});

app.listen(3000);

For a more complete setup with production + dev server ssr, see SSR Example

Rollup

sm-webpack-config also includes rollup. You can use it as:

const smWebpack = require('sm-webpack-config');

const config = {
	entry: 'src/index.js',
	dest: 'dest/index.js',
	library: 'vutils',
	libraryFormat: 'es',
	minify: false,
	sourceMap: false,

	// overrides for production environment
	$env_production: {
		minify: true,
	},

	// overrides for development environment
	$env_development: {
		minify: false,
	},
};

smWebpack.runRollup({config}).then(() => {
	console.log("Done!");
});

Rollup Configuration Options

const config = {
	// entry point of the script (source)
	entry: 'src/index.js',

	// where to put compiled file
	dest: 'dist/index.js',

	// library name to give to the module
	library: 'lib',

	// what format should the compiled file be in
	// this can be umd, amd, cjs (node like format), es (import / export), iife (for using in <script>)
	libraryFormat: 'umd',

	// whether to uglify the output
	minify: false,

	// whether to generate a sourcemap or not
	sourceMap: false,
};
