Our thoughts on feature requests

Lots of developers rely on gulp, so we don't make big changes very often. Not every feature request will be added to gulp, but hearing about what you want is important. Don't be afraid to submit a feature request!

Describe your idea for a new feature

Add support for loading .mts files, same as .cts.

Explain the problem your idea is trying to solve

I'd like to use native ESM modules, while also using TypeScript. This is what the .mts extension was made to accompplish.

How will it benefit gulp and its users?

Allow loading native ESM modules in node while also using TypeScript to do type-checking.

If this feature could exist outside of gulp (like as a plugin or a module), would you be interested in helping to create and maintain it?

It already exists in ts-node

Thanks for the request. We'll be looking to the community to help implement this; otherwise it won't land in gulp 5 because we have a ton other work to do.
