Packages available

@davesnx/styled-ppx/ppx is the ppx as a binary
@davesnx/styled-ppx/css are the CSS bindings

Update `bsconfig.json`

Add "@davesnx/styled-ppx/ppx" under bsconfig "ppx-flags". The diff on bsconfig.json should contain the following:

{
  "bs-dependencies": [
    "@rescript/react",
+   "@davesnx/styled-ppx/css",
+   "@davesnx/styled-ppx/emotion"
  ],
+ "ppx-flags": ["@davesnx/styled-ppx/ppx"]
}

Note: @rescript/react is optional, and only needed if you use styled components (%styled.div(``)).

Example

module Link = %styled.a((~color=CssJs.hex("4299E1")) => `
  font-size: 1.875rem;
  line-height: 1.5;
  text-decoration: none;
  margin: 0px;
  padding: 10px 0px;
  color: $(color);
`)
 
/* This is a unique className pointing to those styles */
let layout = %cx(`
  display: flex;
  width: 100%;
  height: 100%;
  justify-content: center;
  align-items: center
`)
 
/* Later in a component */
<div className=layout>
  <Link
    color={CssJs.hex("333333")}
    href="https://sancho.dev"
    rel="noopener noreferrer">
    {React.string("sancho.dev")}
  </Link>
