Current project I’m working on uses obsolete version of Meteor. Plus CoffeeScript, IronRouter, ton of global variables and subscriptions.
I want to get rid of it incrementally, so my idea is to start developing another app with React and run it simultaneously with existing on the same database. At first there will be few features, but eventually it will replace the old one.
I care about things like what will happen if person logs in in both version, would data reactively change on one client if changed in another.
In case I don’t change DB schema, would this strategy be ok?
