React JSX Question

Webpack cannot find module

I'm new on webpack and I'd like to use third party react component in my project. I installed the componet that i need and the dir

node_modules
was created and my project's tree look like:

reactcalendar
|--node_modules
| |--.bin
| |--babel-cli
| |--babel-core
| |--babel-preset-es2015
| |--babel-preset-react
| |--babelify
| |--file-loader
| |--moment
| |--react
| |--react-big-calendar (the third party component)
| |--react-dom
| |--webpack
|--.babelrc
|--bundle.js (empty)
|--index.html
|--index.js
|--package.json
|--webpack.config.js


Some file was used for browserify but it gave me the same error...

My index.html look like this:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>React Calendar</title>
<script src="bundle.js" type="text/javascript"></script>
</head>
<body>
<div id="content"></div>
</body>
</html>


My index.js look like this:

import BigCalendar from 'react-big-calendar';
import moment from 'moment';
BigCalendar.momentLocalizer(moment);

ReactDOM.render(<BigCalendar
events={myEventsList}
startAccessor='startDate'
endAccessor='endDate'
/>, document.getElementById('content'));


And my
webpack.config.js
look like this:

module.exports = {
context: __dirname,

output: {
filename: "bundle.js",
path: __dirname
},

module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loaders: ["babel-loader"]
},
{
test: /\.html$/,
loader: "file?name=[name].[ext]",
}
]
},

entry: {
javascript: "./index.js",
html: "./index.html"
}
}


When i run the command
webpack
into my root project it gave me this error:

C:\Users\ernest\PhpstormProjects\reactcalendar>webpack
Hash: ebfe4ff0eeeaed3060c6
Version: webpack 1.13.1

ERROR in ./index.js
Module not found: Error: Cannot resolve module 'react-big-calendar' in C:\Users\ernest\PhpstormProjects\reactcalendar

Maybe I'm wrong with the config file of webpack?

Answer

1.delete node_modules folder.

2.then npm install

3.Change your code in index.js to this

import {render} from 'react-dom';
import React from 'react';
import BigCalendar from 'react-big-calendar';
import moment from 'moment';

BigCalendar.setLocalizer(BigCalendar.momentLocalizer(moment));
const myEventsList = [{'event':'test2'},{'event':'test1'},{'event':'test3'}]

render(<BigCalendar
    events={myEventsList}
    startAccessor='startDate'
    endAccessor='endDate'
/>, document.getElementById('content'));

4.in index.html you should put bundle.js into body

<body>
    <div id="content"></div>
    <script src="bundle.js" type="text/javascript"></script>
</body>
