truffle-save-networks-plugin

Truffle plugin for saving/loading networks info from/to artifacts.

npm install --save-dev truffle-save-networks-plugin

To save known networks declared in truffle-config.js from artifacts into networks.json, use

truffle run save-networks

To load networks from networks.json and merge that info with the info present in artifacts, use

truffle run load-networks

May be worthwhile to run truffle networks --clean if producing build files.
