@hanzei Will test it by end of this week, if this is not of high priority. Please let me know if this needs to be tested urgently.

@mickmister Should we merge the above PR and start creating HW (typescript migration) tickets?

[mickmister]

@ayusht2810 Yeah merged :+1:

[mickmister]

@ayusht2810 Before creating the tickets, I think we should have one example PR that shows how to convert a given component (and index.ts file in the case of this project), to show how a given typescript migration can be done, and also to validate the current state that it is ready for components to be migrated
