Transform TypeScript into ES.next.
Does not type-check its input. For that, you will need to install and set up TypeScript.
- Does not support
namespace
s. Workaround: Move to using file exports, or migrate to using themodule { }
syntax instead. - Does not support
const enum
s because those require type information to compile. Workaround: Remove theconst
, which makes it available at runtime. - Does not support
export =
andimport =
, because those cannot be compile to ES.next. Workaround: Convert to usingexport default
andexport const
, andimport x, {y} from "z"
.
In
const x: number = 0;
Out
const x = 0;

Replace the function used when compiling JSX expressions.
This is so that we know that the import is not a type import, and should not be removed
