Cannot find module "ngx-gallery" - ASP.NET Core 2 Angular 4 template

See original GitHub issue

Hi @lukasz-galka ,

When I try to use the library in the new ASP.NET Core 2 Angular template (VS 2017) the module cannot be loaded. The template uses webpack, more specifically:

There is a webpack.config.vendor.js file where you declare the 3rd party libraries. For yours this is the relevant parts;

const nonTreeShakableModules = [
    'bootstrap',
    'bootstrap/dist/css/bootstrap.css',
    'es6-promise',
    'es6-shim',
    'event-source-polyfill',
    'font-awesome/css/font-awesome.css',
    'ngx-gallery/lib',
    'jquery',
];

const serverBundleConfig = merge(sharedConfig, {
        target: 'node',
        resolve: { mainFields: ['main'] },
        entry: { vendor: allModules.concat(['aspnet-prerendering']) },
        output: {
            path: path.join(__dirname, 'ClientApp', 'dist'),
            libraryTarget: 'commonjs2',
        },
        module: {
            rules: [ { test: /\.css(\?|$)/, use: ['to-string-loader', isDevBuild ? 'css-loader' : 'css-loader?minimize' ] } ]
        },
        plugins: [
            new webpack.DllPlugin({
                path: path.join(__dirname, 'ClientApp', 'dist', '[name]-manifest.json'),
                name: '[name]_[hash]'
            })
        ],
        externals: [nodeExternals({
            whitelist: ['/^ngx-gallery/']
        })]
    });

As you can see I have excluded ngx-gallery but still doesn’t work, I get the following errors (part of them) when I run webpack --progress

Thanks
