2

I tried following this repo:-

But I am getting the following error on compiling the code with :-

code = fs.readFileSync('Voting.sol').toString()

solc = require('solc')

compiledCode = solc.compile(code)

It throws out this error:-

'{"errors":[{"component":"general","formattedMessage":"* Line 1, Column 1\n  Syntax error: value, object or array expected.\n* Line 1, Column 2\n  Extra non-whitespace after JSON value.\n","message":"* Line 1, Column 1\n  Syntax error: value, object or array expected.\n* Line 1, Column 2\n  Extra non-whitespace after JSON value.\n","severity":"error","type":"JSONError"}]}'

  The compile function takes different arguments depending on which version you have. Make sure to check documentation github.com/ethereum/solc-js#readme

You have to specify what type of encoding is used for the solidity file.

code = fs.readFileSync('Voting.sol', 'utf8');

and you have to specifiy the number of contracts your are about to compile.

compiledCode = solc.compile(code, 1);

I found another solution. In my case the problem was that the File.sol was raw solidity smart contract, but you need to put Compiler Standard Input JSON into solc.compile(). This works for Solidity 0.5.1. In this thread is my whole process step by step until the transaction sending.
