css-rule-stream

transform stream to cut css into rule-sized chunks, which come in the form:

{
  content: "your css"
}

Example:

var rules = require('css-rule-stream'),
    ldjson = require('ldjson-stream');
 
fs.readFileSync(__dirnam + '/main.css')
  .pipe(rules)
  .pipe(ldjson.serialize())
  .pipe(process.stdout);

main.css

div {
  background: red;
}

.cls {
  color: green;
}

#id {
  font-size: 10px;
}

/* comment */

@media screen and (min-width: 1000px) {
  a {
    text-decoration: underline;
  }
}

a:hover {
  font-weight: bold;  
}

section 


{
  margin: 0;
  /* comment wthin a rule */
  padding: 5px;
}


body > * {
  
}

{"content":".cls {\n  color: green;\n}"}
{"content":"#id {\n  font-size: 10px;\n}"}
