Router doesn't export the QueryParamsHandling interface anymore

🐞 bug report

Affected Package

The issue is caused by package @angular/router

Is this a regression?

Yes, the previous version in which this bug was not present was: angular 7.*

Description

After migrating to angular 8.0 using the command ng update @angular/cli @angular/core The compiler started to complain about error TS2305: Module '"@angular/router/router"' has no exported member 'QueryParamsHandling'.

I use this for importing the QueryParamsHandling interface 👍

import { QueryParamsHandling} from '@angular/router/src/config';

Should I import it from else where ?

🔥 Exception or Error

error TS2305: Module '"@angular/router/router"' has no exported member 'QueryParamsHandling'.

Imho, this is a bug. The property is flaged as part of the public API. But it’s missing in the index.ts. The rest of the NavigationExtras interface seems to be part of the API so it make no sense to hide property types.

We explicitly don’t consider the following to be our public API surface:

• any file/import paths within our package except for the /, /testing and /bundles/* and other documented package entry-points.

https://github.com/angular/angular/blob/master/docs/PUBLIC_API.md

This is never a public API and should not work in any version.
