Input:

import fetch from 'fetch';

var Routes = {
    route1: {
        component: require('Foo')
    },
    route2: {

    },
    route3: {
        component: require('Baz')

I started looking into recursively handling subdirectories when Module Names clashed, but this is a relatively tricky problem.

Would probably have to do a second foreach function that handles all module names that occurs before we actually create the Import Statement.

This example may explain why in a bit of a better way:

import fetch from 'fetch';

var Routes = {
    route5: {
        component: require('Redesign/Foo')
    },
    route1: {
        component: require('Foo')
    },
    route2: {
        component: require('Bar')
    },
    route3: {
        component: require('Baz')
    },
    route4: {
        component: require('Foo')
    },
    route6: {
        component: require('Redesign/Bar')
    },
};
module.exports = Routes;

Warnings:

Could not map: Foo in file: codeModExample.js, skipping.
Could not map: Foo in file: codeModExample.js, skipping.

Output:

var Routes = {
    route5: {

    },
    route2: {
        component: Bar
    },
    route3: {
        component: Baz
    },
    route4: {
        component: require('Foo')
    },
    route6: {
        component: require('Redesign/Bar')
    },
};

module.exports = Routes;
