A stylus plugin to convert px to relative length units (vw / rem)

I maintain a Postcss Plugin for more common usage. Please visit postcss-px-to-relative-unit

npm install stylus-px-to-relative-unit

// webpack.config.js
const pxToUnit = require('stylus-px-to-relative-unit')
...
{
  loader: 'stylus-loader',
  options: {
    use: [pxToUnit({
      // Options
    })],
  }
},
...

pxToUnit({
  targetUnit: 'vw',
  ignoreThreshold: 1,
  viewportWidth: 375,
  viewportHeight: 667,
  htmlFontSize: 37.5
})

If you want to use unit vw and also worry about browser support, you can use 'vw&rem' mode. For example:

// Input 
.test
  border 3.75px solid #fff

// Output
.test {
  border: 0.1rem solid #fff;
  border: 1vw solid #fff;
}

For browser doesn't support vw, it will automatically use rem to layout.

Notice: If you need to limit max/min width of the layout, this mode is not suit for you

For special files don't want to be converted, add 'need-convert = false' on top of each stylus files.

// Input
need-convert = false
.test
  width 3.75px

// Output
.test {
  width: 3.75px;
}

This plugin will not convert px arguments in css functions like 'translate()', but provides some global stylus functions for users to convert px value manually.

// Input
.test
  transform translate(px2vw(3.75px), px2vw(3.75px))

// Output
.test {
  transform: translate(1vw, 1vw);
}

// Input
.test
  transform translate(px2rem(3.75px), px2rem(3.75px))

// Output
.test {
  transform: translate(0.1rem, 0.1rem);
}

For arguments don't want to be converted, wrap them with quote.

// Input
.test
  padding '3.75px' 3.75px

// Output
.test {
  padding: 3.75px 1vw;
}

• Add 'needConvert' option

• Optimize output in 'vw&rem' mode

• Support option targetUnit 'vw&rem'
