I'm building an Angular 6 app, but every time I want to serve to localhost, I get these errors:

None of the modules mentioned above exist in my node_modules file (I can install some of them, but 'crypto', for example, is built in now). How can I get those folders? It's driving me nuts.

Turns out, that if your project has dependencies that require 'fs', 'path', 'child_process' etc. The angular compiler fails to compile the code. To get around this, as someone has already suggested, add (window as any).global = window; to your polyfills.ts. In my case, I had chokidar, node-pty and electron as a dependency. This worker for me.
Setting 'crypto': false in the browser section of package.json tells ng serve not to attempt to bundle that file. Ref You are using the latest version of Angular CLI. Some npm packages are no longer supported. It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in. This is not a reproducible fix.
@Codebrekers You need to add false because those libraries should not be available in the browser. If you would actually need them you would need to use dependencies like browserify-zlib. How does it work in angular 10? This doesnt work for me
The accepted answer is correct; you can't use fs anymore in Angular v6+. However, this alternative builder (it's an extension to the Angular CLI) allows you to target an Electron environment and have full access to Electron's features:
This is caused by dependencies importing node modules that are not available in the browser. Add to your package.json the modules that give errors:
"browser": { "http": false, "https":false, "net": false, "path": false, "stream": false, "tls": false } You are using the latest version of Angular CLI. Some npm packages are no longer supported. It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in.
To fix your issue with crypto, stream libs, go to,
node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js
file and do the following change,
`node: {crypto: true, stream: true}` If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
