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 application migration schematic will now attempt to detect the usage
of custom postcss plugins within a workspace and install the `postcss` dependency
if required. This will only occur if the migration analysis allows for
the conversion to use the `@angular/build` package instead of the
`@angular-devkit/build-angular` package. Custom postcss configurations will
be detected within the same locations as the build system itself which includes
the workspace root and any project root for the `postcss.config.json` and
`.postcssrc.json` files.
The application migration schematic will now attempt to detect the usage
of Less stylesheets within a workspace and install the `less` dependency
if required. This will only occur if the migration analysis allows for
the conversion to use the `@angular/build` package instead of the
`@angular-devkit/build-angular` package. The Less usage detection may
not detect Less stylesheets within Node.js packages and currently does
not handle the case where a project only has inline Less stylesheets.
More complex analysis may be added in the future. However, a build time
error message will be presented with instructions to install `less` in
these cases if the stylesheet preprocessor is required and not present.
