I tried to do the server side render using renderToString method.
function handleRender(req, res) {
const html = renderToString(
<Counter />
);
res.send(renderFullPage(html));
}
function renderFullPage(html) {
return `
<!doctype html>
<html>
<head>
<title>React Universal Example</title>
</head>
<body>
<div id="app">${html}</div>
<script src="/static/bundle.js"></script>
</body>
</html>
`
}
If the component like following it works:
Counter.js
const Counter = () => {
function testClick(){
console.log('test');
}
return (
<div>
<div onClick={testClick.bind(this)}>
test
</div>
</div>
);
};
export default Counter;
However, if I change Counter.js into following:
class Counter extends React.Component {
testClick(){
console.log('click');
}
render() {
return (
<div>
<div onClick={this.testClick.bind(this)}>
test btn
</div>
</div>
)
}
}
export default Counter;
It will show errors:
Uncaught Error: locals[0] does not appear to be a `module` object with Hot Module replacement API enabled. You should disable react-transform-hmr in production by using `env` section in Babel configuration.
So how to use React.Component with renderToString method?
I minimize the project and push to Github. Please have a look.
