Consider supporting webpack.config.mjs alongside webpack.config.js

[TomasHubelbauer]

Do you want to request a feature or report a bug?
Feature.

What is the current behavior?
webpack.config.mjs cannot be used in place of webpack.config.js.

What is the expected behavior?
webpack.config.mjs could be used instead of webpack.config.js.

If this is a feature request, what is motivation or use case for changing the behavior?
Consistency.

It's a valid request, but not possible to do without changing the config loading to be asynchronous and using import() (only available as of node 9.5.0?)

[TomasHubelbauer]

@Kovensky There is --experimental-modules which could be set to enable import, but I've mostly opened this feature request so it's tracked for when in the future doing this is feasible. Right now ECMAScript module support is still too new.

That shouldn't be an issue. We already support exporting a promise from webpack.config.js.

@webpack-bot move to webpack/webpack-cli

I've moved it to webpack/webpack-cli.

Is this approved? Can we define webpack.config.mjs in next versions?

[TomasHubelbauer]

@damianobarbati See the moved issue webpack/webpack-cli#282. This will probably take a good, good bit of time to be implemented and released.
