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)
This commit adds an option to the `CommonEngine` to enable performance profiling. When enabled, timings of a number of steps will be outputted in the server console.
Example:
```
********** Performance results **********
Retrieve SSG Page: 0.3ms
Render Page: 25.4ms
Inline Critical CSS: 2.3ms
*****************************************
```
To enable profiling set `enablePeformanceProfiler: true` in the `CommonEngine` options.
```ts
const commonEngine = new CommonEngine({
enablePeformanceProfiler: true
});
```
This removes the util function for express, instead the "CommonEngine" is called directly infuture before this package is final we might rename the "CommonEngine" to something else.
