[vidal7]

Version

2.7.10

Reproduction link

github.com

Steps to reproduce

• Clone the repo
• npm install
• npm run compile

What is expected?

No typescript compilation errors

What is actually happening?

There is typescript compilation errors

---

Since 2.7.5 and 005e52d, $emit cannot be typed with vue-class-component.

If you checkout commit 62000a803bbe4ed1dc9d30c20772a948cab49d16 and doing npm install to go back in vue 2.7.4 and npm run compile, everything is fine.

See file src/ComponentWithTypedEvents.ts to see examples about working typing of events.
