The TypeScript `isolatedModules` option is now enabled for all TypeScript
code within the repository. As a result, all packages will now be built
with the option enabled. This does not affect projects created with the CLI
and is only related to the building of the actual Angular CLI code.
The `isolatedModules` option ensures that code can be emitted without the
TypeScript typechecker and allows tools other than TypeScript to potentially
be used. Code was updated to correct all errors after the option was enabled.
Additionally, some early code fixes were done to add function and accessor
return types to prepare for future `isolatedDeclarations` usage. More changes
would be needed to consider turning on `isolatedDeclarations`, however.
Updates for all angular.io links to the new angular.dev domain. Additionally, adjustment to new resources where the equivalent does not exist on the new site (e.g. Tour of Heroes tutorial)
The source code for the builders within the `@angular-devkit/build-webpack` package have been moved
into a `builders` subdirectory to more closely align with the structure of the builders in the
`@angular-devkit/build-angular` package. An initial `package.json` exports field definition has also
been added that currently continues to allow deep imports.
With this change the builder will report the emitted chunks and assets after the compilation, this is needed for deferential loading so that we can build an index from the outputs of multiple builds
