Solidity is a contract-oriented, high-level programming language for implementing smart contracts.

Solidity

• Solidity is a contract-oriented, high-level programming language for implementing smart contracts

• It was influenced by C++, Python and JavaScript and is designed to target the Ethereum Virtual Machine (EVM)

• Solidity is statically typed, supports inheritance, libraries and complex user-defined types among other features

• Solidity was first publicly discussed in 2014 and its first version was released in 2015

• Solidity is developed by the Ethereum Foundation and a large community of contributors

• Solidity is used to create smart contracts on the Ethereum blockchain

Installation of Solidity using npm

• Step 1: Install solc using npm

    sudo npm install -g solc
  

• Step 2: Check the version of solc

    solcjs --version
  

• Step 3: Compile the Solidity code

    solcjs --bin --abi HelloWorld.sol
  

• Step 4: Create a file named HelloWorld.js

    var solc = require('solc');
    var fs = require('fs');
    var input = fs.readFileSync('HelloWorld.sol');
    var output = solc.compile(input.toString(), 1);
    console.log(output.contracts[':HelloWorld'].bytecode);
    console.log(output.contracts[':HelloWorld'].interface);
  

• Step 5: Run the HelloWorld.js file

    node HelloWorld.js
