Please Describe Your Addition

See https://github.com/rollup/awesome/pull/66 – and sorry for the inconveniece! In the meantime, I've released the package under @rbnlffl/rollup-plugin-eslint. The reason for this plugin to exist is still the same: The most popular integration between rollup and ESLint, rollup-plugin-eslint, hasn't been touched in over a year now and references eslint@^6.0.0, resolving to v6.8.0, thus preventing you from using newer features.

@TrySound would you be interested in a PR to update the plugin? I'd like to avoid duplicate plugins in the list if at all possible, but @robinloeffel does have a good point that it's very out of date.

[TrySound]

Oh, right. I forgot about this plugin. Will look into it.

Any updates?
