[v3.1.2] (Aug 31 / Sept 1 2022)

Migrate UI components into TypeScript
This doesnt affect anyone, it a step in task to migrate the project source code into TS

Fixes:

• Type defn: Change type of react elements to React.ReactElement

  • Change every React.ReactNode and React.Component to React.ReactElement
  • Use the type of SendbirdError
  • Use the type MessageSearchQueryParams
  • Use enum MessageSearchOrder.TIMESTAMP in the message search query params instead of 'ts' as const

  ReactNode could be string | number | null | undefined | ReactElement | portal and this(expecting string or number) causes warning when we use it like <CustomComp />

  // in the component
  { renderMessage } = props
  const CustomMessage = useMemo(() => {
    return renderMessage({ ... });
  }, []);
  return (
    <div>
      <CustomMessage />
    </div>
  );

  so expecting ReactElement is better for our case

• Fix message grouping:
  Set isMessageGroupingEnabed to true(was set to false during v2 migration)
