Libraries that have already been wrapped with BuckleScript bindings are customarily prefixed with
bs-director. Here's a search for all of the BS related libraries on NPM.
If you can't find what you're looking for: sometimes you don't need a binding to use a JS library. Most JS data types, such as array and objects, map over cleanly to Reason and vice-versa. You also have access to the familiar JS API. Be sure to also check the "Interop" and "Converting from JS" sections here!
