node package manager



Lisk JS is a JavaScript library for Lisk - the cryptocurrency and blockchain application platform. It allows developers to create offline transactions and broadcast them onto the network. It also allows developers to interact with the core Lisk API, for retrieval of collections and single records of data located on the Lisk blockchain. Its main benefit is that it does not require a locally installed Lisk node, and instead utilizes the existing peers on the network. It can be used from the client as a browserify compiled module, or on the server as a standard Node.js module.
