Split react code into react library bundle and components bundle
Question
I have the following configuration for webpack (integrated with grunt):
var path = require('path');
var webpack = require('webpack');
module.exports = {
run_webpack: {
entry: {
react: "./static/src/jsx/react.jsx",
index: "./static/src/jsx/index.jsx"
},
output:{
path: "./static/js/",
filename: "[name].bundle.js",
},
module: {
loaders: [
{
test: /.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
query: {
presets: ['es2015', 'react']
}
}
]
},
},
};
My react.jsx and index.jsx:
// react.jsx
var React = require('react');
var ReactDOM = require('react-dom');
// index.jsx
ReactDOM.render(
<h1>Hello, world!</h1>,
document.getElementById('app')
);
And then I embed those bundles into html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Kanban app</title>
<script src="//code.jquery.com/jquery-1.12.0.min.js"></script>
<script type="text/javascript" src="{% static 'js/react.bundle.js' %}"></script>
<script type="text/javascript" src="{% static 'js/index.bundle.js' %}"></script>
</head>
<body>
<div id="app"></div>
</body>
</html>
My problem that it doesn't render <h1>Hello, world!</h1> . The error is 'ReactDOM is not defined'. How can I overcome that issue? It works when I merge react.jsx and index.jsx , but still would like to keep them separately to accelerate code compiling.

Your index.jsx simply has to depend on react and react-dom for the code to work. To achieve what you want, you can load them using externals , though. You could set up something like this for the target generating index :
externals: {
'react': {
commonjs: 'react',
commonjs2: 'react',
amd: 'React',
root: 'React'
},
'react-dom': 'react-dom'
},
This way webpack won't bundle react and react-dom to your index bundle.
