WARNING in ./node_modules/memfs/lib/process.js 20:15-33
Module not found: Error: Can't resolve 'process' in '/Users/nick/Documents/NativeScript/Projects/WFSL/node_modules/memfs/lib'
Did you mean './process'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (/Users/nick/Documents/NativeScript/Projects/WFSL/node_modules, node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "process": require.resolve("process/browser") }'
- install 'process'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "process": false }

The above file is in the WFSL/app folder not under WFSL as indicated above why is this now an issue.

Cannot find any details regarding loaders for png or jpg files for Webpack.

I've done ns clean

webpack.config.js file is

`
const webpack = require("@nativescript/webpack");

 module.exports = (env) => {
        webpack.init(env);

        // Learn how to customize:
         // https://docs.nativescript.org/webpack

         return webpack.resolveConfig();

};
`

Why is upgrading NS version so problematic. NS5 to NS6 I had issues. NS6 to NS7 I had issues and now NS7 to NS8. There never appears to be a clean migration.

webpack.config.js から始め、報告されている依存関係と app.js のパスを使って NS7-to-NS8 のビルドを再現します。memfs、image-loader、app.js について記載されている解決失敗を確認します。報告された webpack エラーなしで移行をビルドできれば完了です。
