My story is I wrote PORO and compiled to JS via (http://opalrb.org/try/#) and downloaded (http://cdn.opalrb.org/opal/current/opal.js) and put it in my vendor. and tested my compiled js in rails server and it worked perfect. But I would like to use that compiled js without rails server. Therefore, I put opal.js and compiled js in simple html file and it test on browser and it does raise error on opal.js but when I replaced downloaded opal.js with cdn link, it worked.
@htoo-eain-lwin could be related to bootstrapping, my advice is to use the gems we provide to get a better more solid experience For rails: gem "opal-rails" For simple HTML files: gem install opal; opal -e "puts 'hello world'" -c > hello.js and then use hello.js in your HTML file
@fkchang saw the video and kinda read the thread (thanks to twitter broken thread viewer), he didn't seem very interested but the final advice seems good: remove any pain-points the user might encounter
