I'm submitting a:

[ x] bug report
[ ] feature request
[ ] support request => Please do not submit support requests here, use one of these channels: https://stencil-worldwide.herokuapp.com/ or https://forum.ionicframework.com/

Current behavior:
Stencil throws many warnings:-

• @prop() "history" on is immutable but was modified from within the component
• @prop() "location" on is immutable but was modified from within the component.
• @prop() "routeViewsUpdated" on is immutable but was modified from within the component.
• @prop() "historyType" on is immutable but was modified from within the component.

Expected behavior:
N/A

I'm also facing this same exact issue.

I'm also facing the same issue. Additionally, some of our components are outputting this as well as soon as I updated to Stencil v2.4.0

I too am facing this issue

Can we add an option in the stencil.config or environment variable that will stop these warnings from showing? I would be willing to PR it myself worst case scenario

Hey folks,

I apologize this has taken so long to get looked at. As of earlier this month, we've moved the router to the Stencil Community group. As a result, the Stencil team is no longer maintaining the Stencil router. While these warnings are expected of @Props in Stencil components that are mutated in a component, I believe to properly silence them for the router specifically would require some rework of the router.

I'm going to see if GH will let me move this issue to the new stencil community repo for the router...
