Formerly known as Steem Stream, Hive Stream is a tastefully renamed library for working with the Hive Blockchain. It allows you to watch for specific actions and events on the blockchain and execute code accordingly.
Rather than reiterate what the readme already says, check out the code and repository for a more up to date explanation of what it does and how it works. If you're a dApp developer or looking to build a dApp this will make your life a lot easier and save you some work.
The code can be found on GitHub [here] (https://github.com/Vheissu/hive-stream). As always, contributions are always welcomed by the community.
