Building an Angular app without the Angular cli
(i.e. no ng-serve or ng-build).
So I am transpiling and getting the polyfills with the tools below
Tools/packages:
- I am using gulp to run each task I need.
- I am also using @babel/polyfill, babelify, browserify, and tsifiy
Github repo link:
https://github.com/lgavSKOPOS/testing/tree/5a0e5da4f566049d504dfad818a1eeb1c661cc66
I followed this link initially to get this done:
It does NOT include any info on using this method with Angular. Only typescript transpiling through Babel and using Browserify
I then added my polyfills using @babel/polyfills, but I still get the same error. I have followed the following links to see if these could solve my problem:

};
var fs = require("fs");
var del = require("del");
gulp.task("copy-html", function() {
return gulp.src(path.pages)
.pipe(gulp.dest("dist"));
});
gulp.task("clean:frontend", function() {
return del(`dist/**/*`, `!dist/TestAng/*`);
});

Please let me know if I have added too much code and I will edit this post for better readability
Expected results: Angular app would start running and I could access the App Component and Module
Actual results: Cannot access components/modules although they are seen in Source. Can still see what is happening in index.html. Also got Error: - Can't resolve all parameters for ApplicationModule: (?).
Update 1: I may try using ngc in gulp instead but I am not sure if that will clash with my polyfills problem
