Support ES module

Are there any plans to support ES modules?

CommonJS's Dynamic require is often not supported by the transformer, so it may not run on other runtimes. (mainly Deno).

Start by locating the transformer and reviewing how it loads or emits modules; the issue names no files or tests. Compare the current CommonJS behavior with ES module requirements, especially for Deno. The work is done when the supported module format and runtime behavior are defined and verified.
