How to use Sass along with React? Should I use post-processor(e.g: PostCSS) instead of pre-processor like Sass?

I went through some articles about using Sass along with react which were really confusing. None of them properly saying how to use Sass with react. In node-sass , there are lot of issues so I couldn't make it possible. Can anyone give me proper idea about this? Also I have a doubt that is it good idea to use Sass along with react?
