This is my webpack.config.js file:
const webpack = require('webpack');
const path = require('path');
module.exports = {
cache: true,
devtool: 'source-map',
entry: {
app : [
'./src/index.js'
],
vendor: ['lodash']
},
output: {
filename: 'bundle.js',
path: path.join(__dirname, 'dist'),
publicPath: '/dist/',
pathinfo: true
},
module: {
loaders: [
{ test: /\.js$/, exclude: /node_modules/, loaders: ['babel'] },
{ test: /\.scss/, exclude: /node_modules/, loaders: ['style', 'css', 'sass'] }
]
},
plugins: [
new webpack.NoErrorsPlugin(),
new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.bundle.js', Infinity)
]
};
And this is my scripts that runs the webpack-dev-server:
const webpack =require('webpack');
const WebpackDevServer = require('webpack-dev-server');
const webpackConfig = require('../webpack.config');
const _ = require('lodash');
const webpackDevConfig = _.cloneDeep(webpackConfig);
const devPort = 3000;
webpackDevConfig.entry.app.unshift('webpack/hot/dev-server');
webpackDevConfig.entry.app.unshift('webpack-dev-server/client?http://localhost:' + devPort + '/');
webpackDevConfig.plugins.push(new webpack.HotModuleReplacementPlugin());
new WebpackDevServer(webpack(webpackDevConfig), {
publicPath: webpackConfig.output.publicPath,
hot: true,
stats: {
colors: true,
chunks: false
}
}).listen(devPort, 'localhost');
The webpack
command output is good (bundle.js and vendor.bundle.js), however, the dev server fails with webpackJsonp is not defined
(although its in-memory compilation succeeded).
When removing CommonsChunkPlugin
from webpack.config.js - it all works fine:
...
entry: [
'./src/index.js'
],
...
plugins: [
new webpack.NoErrorsPlugin()
]
Any ideas?
In your index.html file just call vendor.bundle.js before bundle.js
<script src="assets/js/vendor.bundle.js"></script>
<script src="assets/js/bundle.js"></script>
That's all, now it should work. More information.
