babel-plugin-stilr-classnames

This plugin does the following things:

• Locate any and all occurences of the call expression stilrcx(...) in your code. That is, stilrcx will be treated like a special compile-time macro.

• Statically evaluate the return value of the function call using stilr-classnames. This means all of the arguments must be eligible for static evaluation. This plugin should do its best to dig through your code to allow as much static evaluation as possible. If any of the arguments cannot be statically evaluated, then an error will be thrown.

• If static evaluation succeeds, replace the function call with the return value of the function call.

• After the above happens for all occurrences of stilrcx(...), this plugin will use stilr to render a stylesheet containing all of the styles you defined via stilrcx(...).

• Finally, if process.env.NODE_ENV === 'production', global.stilrStylesheet is set to the stylesheet that just got rendered.

• If process.env.NODE_ENV !== 'production', the following code will be added to the top of your program:

var stilrStyleElem =
    document.getElementById('babel_stilrcx_style');
if (!stilrStyleElem) {
  stilrStyleElem = document.createElement('style');
  stilrStyleElem.id = 'babel_stilrcx_style';
  document.head.appendChild(stilrStyleElem);
}
stilrStyleElem.textContent = "the stylesheet that just got rendered";
