I have following configuration
webpack.config.js:
var webpack = require("webpack");
var path = require("path");
var DIST_DIR = path.resolve(__dirname,"dist");
var SRC_DIR = path.resolve(__dirname,"src");
var config = {
entry:
{
'index':SRC_DIR + "/app/index.js",
'home':SRC_DIR + "/app/home.js",
'profile':SRC_DIR + "/app/profile.js"
},
output: {
path: DIST_DIR + '/app',
filename: "[name].bundle.js",
publicPath: "/app/"
},
plugins: [
new webpack.optimize.CommonsChunkPlugin({
name: "common",
chunks: ["index", "home","profile"]
})],
module:{
loaders:[
{
test: /\.js?/,
include: SRC_DIR,
loader: "babel-loader",
query:{
presets:['react','es2015','stage-2'],
}
}
]
},
devServer: {
historyApiFallback: true
}
}
module.exports = config;
Now, I want to load common.bundle + index.bundle in case of index.js, common.bundle + profile.bundle in case of profile.js and so on.
I have only one index.html file, I want to load these three bundles separately whenever corresponding url is hit.

Is it possible with only one index.html file? Do I need more than one html?

Hi I have the folder structure like as follows:-

</html>
..
<link rel="stylesheet" type="text/css" href="./index.css">
the above line is not loading my index.css into browser while inside src/components level, i do have css files, whichare properly getting bundeled and delivered in bundle.css file.
Any help would be of great help
The link to the css should be:
<link rel="stylesheet" type="text/css" href="/index.css">
This should be like this due to the publicPath. Since it is not set, it is by default /.
The link to the css should be:
<link rel="stylesheet" type="text/css" href="../src/index.css">
I just finished learning ReactJS and was trying to go start learning webpack. I was curious if I could turn my existing website (server-side) structure into react type website (SPA). But my only issue is that I am using a lot of vendor js and css files.

The online tutorials kind of confuse me as a beginner in Webpack. So if someone could help me out in this particular use-case, it will help me better understand webpack in general.
I am using webpack to set up a React app.
When I serve my app locally using webpack-dev-server I get VM1086 bundle.js:9812 Uncaught ReferenceError: React is not defined in the console.
I have know idea what is going on as there aren't any other errors or information to go on, as webpack seems to compile ok.
index.html
<html>
<head>
<script src="./dist/bundle.js" ></script>
</head>
<body>
<div id="mount"></div>
</body>
</html>
webpack config
var path = require('path');
module.exports = {
entry: [
'./src/App.js',
],
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.js$/,
exclude: ['node_modules'],
loader: 'babel-loader',
query: {
babelrc: true,
},
}
]
}
}
app.js
import React from 'react';
import ReactDOM from 'react-dom';
console.log('Hello World!');
class App extends React.Component {
render() {
return (<div>314159263</div>);
}
}
ReactDOM.render(<App />, document.getElementById('mount'))
try to define bundle.js after <div id="mount"></div> because may be your bundle compiles your code and it does not find where to render the code
</head>
<body>
<div id="mount"></div>
<script src="./dist/bundle.js" ></script>
</body>
</html>
and also in your webpack add this
query: {
presets: ['es2015', 'react']
}
Why am I getting that error in the console of the chrome ?
My code:
index.html
<!DOCTYPE html>
<html>
<head>
<title>hello React</title>
<meta charset="utf-8">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
</head>
<body>
<div id="root">
<!-- my app renders here -->
</div>
<script src="../react-15.3.1/build/react.js"></script>
<script src="../react-15.3.1/build/react-dom.js"></script>
<script src="./dist/bundle.js"></script>
</body>
</html>
main.js
import SalutaMondo from './salutamondo';
var UnaProva = React.createClass({
render: function(){
return (
<div>
<SalutaMondo/>
<div>Ciao Emiliano</div>
</div>
);
},
});
ReactDOM.render(<UnaProva />, document.getElementById("root"));
salutamondo.js
var SalutaMondo = React.createClass({
render: function(){
return (
<h1>Hello World</h1>
);
}
});
module.export = SalutaMondo;
webpack.config.js
const webpack = require('webpack')
const path = require('path')
module.exports = {
entry: [ './src/salutamondo.js', './src/main.js' ],
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.js?$/,
exclude: /node_modules/,
loader: 'babel-loader',
query: {
presets: ['react', 'es2015']
}
}
]
}
}
In your webpack config, you're using the babel-loader. This implies that you're using ES6 style modules. In salutamondo.js, you're using CommonJS style modules. As a result, the babel-loader isn't picking up the module. Can you try:
export default SalutaMondo;
instead of:
module.export = SalutaMondo;
This is likely due to salutamondo.js using CommonJS module format, while main.js is using ECMAScript module. I recommend keeping everything in ECMAScript modules:
var SalutaMondo = React.createClass({
render: function(){
return (
<h1>Hello World</h1>
);
}
});
export default SalutaMondo;
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.
