Support ESM format for config file

[davidsneighbour]

I don't know if this is a bug or maybe a future feature: using a config that is in the ESM format leads to errors:

Instead change the require of .versionrc.js in /home/patrick/github.com/davidsneighbour/kollitsch.dev/node_modules/commit-and-tag-version/lib/configuration.js to a dynamic import() which is available in all CommonJS modules.

Node.js v20.12.2

Does the package understand the config in ESM format and if not is it possible to add this as a feature?

change .versionrc.js to .versionrc.cjs.

this package support cjs extension

Oops, I have mistook the issue as about "supporting Package type=module environment". My suggestion above isn't that relevant then.

I have checked the source code, mjs is not supported as the config is always imported via require. See: https://github.com/absolute-version/commit-and-tag-version/blob/7ebdacd6edd26076eabed753cdcf3070142f5f0d/lib/configuration.js#L19-L20

I guess this would be a feature request.

Off the top of my head, it will need to use dynamic import to load an ESM config and making the code flow async.

I agree, I think this is a feature request. It would definitely be good to have the ability to use ESM for the config.

I believe it would (almost) come for free if we upgraded it to typescript, so I'll tag #29
