    Routr library is an implementation of router-related functionalities that can be used for both server and client. It follows the same routing rules as Express by using the same library. This library does not use callbacks for routes, instead just mapping them to string names that can be used as application state and used within your application later. For instance in Flux, the current route would be held as state in a store.


    For more detailed examples, please check out example applications;

    import Router from 'routr';
    const router = new Router([
            name: 'view_user',
            path: '/user/:id',
            method: 'get',
            foo: {
                bar: 'baz',
            name: 'view_user_post',
            path: '/user/:id/post/:post',
            method: 'get',
    // match route
    const route = router.getRoute('/user/garfield?foo=bar');
    if (route) {
        // this will output:
        //   - "view_user" for
        //   - "/user/garfield" for route.url
        //   - {id: "garfield"} for route.params
        //   - {path: "/user/:id", method: "get", foo: { bar: "baz"}} for route.config
        //   - { foo: 'bar' } for route.query
        console.log('[Route found]:', route);
    // generate path name (does not include query string) from route
    // "path" will be "/user/garfield/post/favoriteFood?meal=breakfast"
    const path = router.makePath(
        { id: 'garfield', post: 'favoriteFood' },
        { meal: 'breakfast' }


    We use Object.freeze to freeze the router and route objects for non-production environments to ensure the immutability of these objects.

    For production environments, it is recommended to use tools like envify along with uglify as part of your build process to strip out the production specific code for performance benefits.

    We use if (process.env.NODE_ENV !== 'production') to wrap around Object.freeze(), so that you can use various tools to build the code for different environments:

    Build with Webpack

    Two main utility plugins:

    Example of the webpack configuration:

        plugins: [
            new webpack.DefinePlugin({
                'process.env': {
                    NODE_ENV: JSON.stringify('production')
            new webpack.optimize.UglifyJsPlugin(),

    Build with Browserify

    Similar to webpack, you can also use the following two utils with your favorite build system:

    • use envify to set process.env.NODE_ENV to the desired environment
    • use uglifyjs to remove dead code.

    Command-line example:

    $ browserify index.js -t [ envify --NODE_ENV production  ] | uglifyjs -c > bundle.js
