What is the current behavior?

Given someone imports a component compiled with dist-custom-element into a Stencil project that uses the dist output target. In the case that the DCE component shares the same runtime as the dist elements we will run into a runtime error.

GitHub Issue Number: #5596

What is the new behavior?

This patch proposes to throw a more meaningful error in these situations.

I wonder if there is a better solution where we detect this at compile time. One idea would be to make the DCE component import an object from the runtime library that is only exported if the runtime is dedicated to DCE components.

Documentation

The externalRuntime property is documented however, we don't particularly mention this use case.

Does this introduce a breaking change?

  • Yes
  • No

If the instance is undefined in this case an error would be thrown anyway in callRender as we pass instance along as undefined.

Testing

I added an e2e test for this scenario.

we might want to create a JIRA ticket for upgrading to WebdriverIO v9 and then leave a TODO here to remove the browser.isChromium check
