roamfs allows you to write your code in your favorite code editor and get it synced to a Roam code block. Ideal for learning [[roam/render]]!
Right now, this is not hosted anywhere, so you'll have to clone this repository, run yarn install and then parcel src/index.ts.
After that, it's the usual... make a block containing {{[[roam/js]]}}, create a Javascript code block below, paste
var s = document.createElement("script");
s.src = "http://localhost:1234/index.js";
s.id = "roamfs";
s.type = "text/javascript";
document.getElementsByTagName("head")[0].appendChild(s);
...and allow the script.
Right click the gray area where the line numbers are of a code block, pick a file, and the file will get synced with that code block whenever you focus your browser.
