`--poll` is a valid command line option (vs. `--poll 1000`). This however will result in a value of 0 which causes polling to be disabled rather than enabled. This change sets a default value of 500 when the commandline flag is used.
With this change we address 2 main issues related to unbound breakpoints:
1) in VS code when having a `baseHref` set.
2) Visual Studio when using an SPA inside a ASP.NET project
For the latter, it seems that there is no way to set a `webRoot`. However, `webpack:///` seems to be handled internally and will be mapped to the `SpaRoot` ie `ClientApp` folder.

`namespace` is always empty which is breaking sourcemaps since when sources start with `/` vscode will not be able to resolve them unless users configure `sourceMapPathOverrides`.
Fixes#15116
It’s very easy to inadvertently import toplevel css in component styles. Since component css is standalone and self-contained, it will never be shared between components and remains as a single large bundle for each component. This in turn adds a large amount of code that must be processed and increases bundle size.

Webpack and its development server assume the presence of two node builtins (`events` & `querystring`). Do to package hoisting npm/yarn will usually place the shims for those two builtins at locations that webpack find them. This is however not guaranteed nor will it work with pnpm which strictly follows the prescribed dependency tree.
To remedy this, the specific node shims are enabled only for the specific internal webpack files that are used within the development server. This ensures that the requirements of these files does not pollute the entire application.
Fixes#13680
This change synchronizes the behavior of classic scripts and module scripts (`type="module"`). Module scripts are deferred by default. Also, certain injected scripts are not considered module scripts even in a ES2015+ build due to the strict mode behavior of module scripts. Deferring such scripts also ensures consistent execution in those scenarios.
This allows the output path of an application's index HTML file to be controlled independently of the input file. The output path for the file will be considered relative to the application's configured output path. This allows an application to contain multiple input index files for different configurations and allow the output file to remain constant. This also enables the placement of the index file in a subdirectory within the output path or change the name of the output index file neither of which was previously possible.
`ng serve` was errantly adding a module type to custom script bundles. These scripts may contain ES5 and non-strict compatible code and can therefore not be marked as module scripts. `ng build` already correctly operates in this fashion.
Fixes#14952
The lazy option inside the script and style option is confusing as this option doesn't lazy load a bundle but rather it doesn't inject/reference the script in the HTML. While this option is an enabler for lazy loading, the users will still need to handle on how how this bundle will be lazy loaded. There are also potential use cases beyond lazy loading for the option.
Closes#14814
With this change we remove styles compilation and copying of assets for the second build when differential loading is enabled.
This should improve the build times for larger applications.
i18n is not yet implemented in Ivy, we should emit a warning stating this and exit gracefully.
This also swaps the readTsConfig logic to use `@angular/compiler-cli` instead of `typescript`. This is needed because when parsing the tsconfig, typescript is not aware of `angularCompilerOptions` and will not merged them if they are at un upper level tsconfig file when using `extends`.
Closes#14225
`caniuse-api` only returns `true` for a feature when it's fully supported. This might causes redundant ES5 builds if users opt to support only browsers which do support ES6 modules but either require polyfills such as Safari 10.1 or when both bundles will be downloaded such as `Edge 18`
See: 1b74c10257/src/index.js (L49) and https://github.com/Nyalab/caniuse-api/issues/82Fixes#14580
10.1 and iOS Safari 10.3
The nomodule polyfill needs to be loaded prior to any script and be
outside of webpack compilation because otherwise webpack will cause the
script to be wrapped in `window["webpackJsonp"]` which causes it to
fail.
This polyfill will only be injected when the either Safari 10.1 or iOS
Safari 10.3 support is required, which is based on the browsers defined in browserslist file.
Fixes#14680
