By default the application will be served with inline mode enabled. This means that a script will be inserted in your bundle to take care of live reloading.
However at the moment we are already adding these scripts in `_addLiveReload` method.
With this change we always disable this behaviour and only add it when needed via the `_addLiveReload` logic.
Eventually we should try to remove the logic and rely on webpack-dev-server interals.
Fixes#14300
When we first started using Build Optimizer, we saw a lot of the savings were tied to using the Uglify/Terser `pure_getters` option.
This was intimately related with the structure and shape of the Angular codebase. The measurements we did at the time on angular.io showed a significant size reduction, from 1mb to about 600kb. Of these roughly 150kb were tied to using `pure_getters` if I remember correctly.
Meanwhile the Angular codebase has changed significantly and I don't really see these savings anymore, so I don't think it makes sense to keep it on given that it is known to cause problems with some libraries.
Closes#9231, #11439, #12096, #12128.
When using differential loading with targets ES5 and ES2016+, the
browser with ESM support will pick `script[type="module"]` scripts even
without supporting ES2016+ syntax.
We want to warn users in this case.
Before, the build tasks ran in parallel and so the different webpack
instances competed over the same lines on the console.
To fail fast and to prevent to show the same errors twice, the second
build step is not executed if the first one fails.
As running these tasks in sequence causes issues with watch mode, this
PR also disables differential loading when watch mode is requested.
This is to align with the folder structure of version 8, were tsconfigs are outside of the `src` folder
Also, this change remove the dud `tsconfig.json` in the `src` folder and instead we add the triple slash lib reference `/// <reference lib="webworker" />` for IDE support.
With this change we turn on differential loading for projects that has es2015 as script target and still want to support browsers which that don't support ES2015.
Supported browsers are defined in the browserlist file.
This change wires up the index generation for multiple bundles, we however don't enable differential loading for users just yet. As this will be done in a separate PR to change over specs to conform with the new files
