Can you provide more details? Are you using preact-compat to load react-router? What version of the react-router library are you using?

[AnkitJainAJ-zz]

yes , i am using preact-compat .
"preact-compat": "3.16.0",
"react-router": "3.0.5"

Please help.

hey @AnkitJainAJ, I'm getting the same issue with react-router. Digging into the source code, it seems that react-router uses create-react-class, which will need to be aliased to the preact-compat version with webpack, browserify or babel, e.g:

// webpack.config.js
module.exports = {
// ...
    alias: {
        'react': 'preact-compat',
        'react-dom': 'preact-compat',
        'create-react-class': 'preact-compat/lib/create-react-class'
    }
}

I hope this helps!
