it is very easy:

import { EffectComposer, DotScreen } from '@react-three/postprocessing'

function App() {
  return (
    <Canvas>
      <EffectComposer>
        <DotScreen scale={2} />
      </EffectComposer>

if you want to use postprocessing in vanilla just follow the github instructions, set up the composer and add the effect.
