Is it possible to make friends gulp sass and postcss plugin?

Question

Node.js

Good afternoon, I had a question, is it possible to make friends between them?
Given -
gulp-sass - https://www.npmjs.com/package/gulp-sass
postcss plugin - https://github.com/alexandr-solovyov/postcss-respo...
An error occurs when trying to compile a piece of code

Code which i am testing

body {
    font-size: {
    0: 1em;
    1600: 2em;
  }
}

Answer 1

Put the postcss call before the gulp-sass call in your task - naturally, gulp-sass cannot digest this tin.
PS In general - it's better not to use such things - overengineering is terrible, you shouldn't deviate so much from "vanilla" CSS, you will work in a team - those who will figure out how it all works after you will thank you.
