Creating libraries in solidity

A library in solidity is a singleton that is deployed once and can be called from any contract. A library in solidity does not have storage and cannot hold Ether. This helps a lot in avoiding duplicate code in the Ethereum blockchain (saves a lot of gas by not deploying the same code again).

In this recipe, you will learn to create, deploy, and interact with libraries using solidity.

Getting ready

You need to have a working Ethereum installation for deploying and testing the smart contract. You can also use the Remix IDE to write and test solidity code.

It is required to have a basic knowledge of solidity to understand this recipe. Go through Chapter 2, Smart Contract Development, for more information...
