I'm trying to utilize the SplitChunksPlugin to produce separate bundles per each page/template in a MPA. When I use the HtmlWebpackPlugin, I get an html file for each page with a script tag pointing to the correct bundle. That is great! However, the trouble I'm having is with my vendor files. I want separate html files to point to only the vendor bundles they need. I can't get each separate html file to point to the correct vendor bundles when the SplitChunksPlugin creates multiple vendor bundles. The bundles produced are:
home.bundle.js
product.bundle.js
cart.bundle.js
vendors~cart~home~product.bundle.js
vendors~cart~product.bundle.js
So basically the home template should reference home.bundle.js, vendors~cart~home~product.bundle.js, and not the second vendor bundle. Only the cart and product templates should reference both vendor bundles. I am utilizing the chunks option for the HtmlWebpackPlugin but can't get it to pull the correct vendor bundles unless I explicitly reference the name of it like so:
chunks: ['vendors~cart~home~product.bundle','home']
But this kinda defeats the purpose of dynamically rendering your script tags. I've tried creating a vendor entry point but this lumps all my vendors together.
Is there some simple config I'm missing?
My webpack.config.js:
const path = require('path');
const webpack = require('webpack');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const Visualizer = require('webpack-visualizer-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
mode: 'development',
devtool: 'cheap-module-eval-source-map',
entry: {
home: './src/js/page-types/home.js',
product: './src/js/page-types/product.js',
cart: './src/js/page-types/cart.js'
},
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, 'dist/js')
},
optimization: {
splitChunks: {
chunks: 'all'
}
},
plugins: [
new CleanWebpackPlugin(['dist']),
new Visualizer(),
new HtmlWebpackPlugin({
filename: 'home.html',
chunks: ['vendors','home']
}),
new HtmlWebpackPlugin({
filename: 'product.html',
chunks: ['vendors','product']
}),
new HtmlWebpackPlugin({
filename: 'cart.html',
chunks: ['vendors~cart~product','cart']
}),
], ...
My js modules:
/* home.js */
import jQuery from 'jquery';
import 'bootstrap';
cart and product also reference the react library:
/* cart.js */
import jQuery from 'jquery';
import 'bootstrap';
import React from 'react';
import ReactDOM from 'react-dom';
/* product.js */
import jQuery from 'jquery';
import 'bootstrap';
import React from 'react';
import ReactDOM from 'react-dom';
Example html output home.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Webpack App</title>
</head>
<body>
<script type="text/javascript" src="home.bundle.js"></script></body>
</html>
