Currently, using OpenZeppelin solidity libraries is limited to local machines and deploying on tools like truffle. IMO Remix is the easiest place to deploy contracts. When I'm teaching solidity workshops I always use remix because it's web based (no download) and beginners find truffle-config.js difficult to setup.
We should create a remix plugin for the solidity library that can grab OZ imported contracts from each file being compiled. Then add them to the batch being compiled. https://github.com/ethereum/remix-plugin
Using github to import the contracts is a good work around for this. i was imagining being able to use
import openzeppelin-solidity/contracts/etc..
the same way that I do when developing on desktop with truffle. I didn’t think of using github for the imports in remix though. I suppose it has the same result by doing that instead.
