我正在尝试在ReactJS应用程序中使用GSAP进行客户端动画制作。如果我通过npm安装gsap模块，然后尝试在模块中使用gsap，则会出现以下错误：
node_modules/gsap/src/uncompressed/TweenMax.js:2535
_doc = document,
^
ReferenceError: document is not defined

ReactJS中是否有编码的方法：如果它在服务器上呈现，则没有文档，因此请不要加载gsap，但是一旦下载了已编译的bundle.js（我的客户端负责接管客户端的js），请使用gsap因为文件存在？
我当前正在使用的解决方法是将gsap嵌入index.ejs中：
<!DOCTYPE html>
<html>
<head>
<title>Solid Website</title>
</head>
<body>
<section id="react-app" class="container-fluid">
<%- markup %>
</section>
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.2/TweenMax.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.2/TimelineMax.min.js"></script>
<script src="build.js"></script>
</body>
</html>
更新：webpack.config.js
var path = require('path');
module.exports = {
entry: path.join(process.cwd(), 'client-render.js'),
output: {
path: './public/',
filename: 'build.js'
},
module: {
loaders: [
{
loader: 'babel'
}
]
}
}
最佳答案
在我的webpack.config.js中：
module.exports = {
entry: path.join(process.cwd(), 'client/client-render.js'),
output: {
path: './public/',
filename: 'build.js'
},
module: {
loaders: [
{
test: /.js$/,
loader: 'babel'
}
]
},
/* this is new */
plugins: [
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: JSON.stringify('production'),
APP_ENV: JSON.stringify('browser')
}
})
]
}
然后在我的模块中：
if (process.env.APP_ENV === 'browser') {
load_the_module_for_browser;
}
