Problem

So, i'm working a web app using Webpack and ES6. When I try to run Webpack, it tells me that it can't resolve "app.js". I've looked all across the internet for a solution, but I just couldn't find one, can someone help me? The Full error is:

ERROR in ./assets/js/main.js
Module not found: Error: Can't resolve 'app.js' in 'C:\Users\sidna\Dropbox\Dev Stuff\Web Apps\Mondrian Generator\assets\js'
 @ ./assets/js/main.js 4:0-17

webpack.config.js

module.exports = {
entry: './assets/js/main.js',
output: {
    filename: 'assets/js/build.js',
},
watch: true,
module: {
    loaders: [
        {
            test: /\.scss$/, loader: "style-loader!css-loader!sass-loader"
        },
        {
          test: /\.js$/,
          exclude: /node_modules/,
          use: {
            loader: 'babel-loader',
            options: {
              presets: ['env']
            }
          }
        }
    ],
}
};

app.js (Empty)

main.js

// SCRIPTS
require("app.js");

require("../css/large.scss");

When the import is neither an absolute path (starting with /) nor explicitly a relative path (starting with ./ or ../), it is resolved as a module, which means it's Loading from node_modules Folders.

Your app.js is not in node_modules, so you need to change it to a relative path (assuming it's in the same directory as main.js):

require("./app.js");

Webpack follows the import behaviour of Node.js, but it also allows you to change it with the resolve.modules option.
