Using PostStylus in a node script

[d0t15t]

Hi, thanks for this plugin.

I'm trying to use poststylus in a node script, but none of the plugins are being applied. The following outputs the compiled stylus->css, but the postcss plugins are not working. What am i doing wrong?

    stylus(data)
      .use(poststylus([
        'autoprefixer',
        'cssnano',
      ]))
      .render((err, css) => {
        fs.writeFile(cssFullFilePath, css)
      })
