Openchain dependency : assert & buffer

[monomy001]

Hi, I'm trying to implement open chain on my webproject, however I found that latest commit is half a year ago. Is openchain js still maintained?

using the latest 0.2.4, upon compiling on react native, it generates error
Requiring unknown module "buffer". If you are sure the module is there, try restarting the packager or running "npm install"

So I tried adding buffer manually on package.json, similar error happens with "assert"..
when I add "assert" into package.json, error becomes unknown variable Buffer.
Please advise.

Thanks
