npm install- use
./node_modules/.bin/ganache-clistart a ganache test chain - use
./node_modules/.bin/solcjs --abi --bin Voting.solto get the abi and code bin file - in the node-cli
var Web3 = require('web3')var web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:8545'))- use
web3.isConnected()test whether the web3 connected the ganache chain or not - copy the content of the abi and the bin
var abi ={the content of the abi}var bytecode={the content of the bin}var VotingContract = web3.eth.contract(abi)contractInst = VotingContract.new(["Alice","Bob","Cary"],{data:bytecode,from:web3.eth.accounts[0],gas:5000000})after this you can see a json data about the contract in the cli- get the address of the contract
contractInst.address
Anyway,my abi is like this:
[{"constant":true,"inputs":[{"name":"candidateName","type":"bytes32"}],"name":"totalVotesFor","outputs":[{"name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"","type":"bytes32"}],"name":"votesReceived","outputs":[{"name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"candidateName","type":"bytes32"}],"name":"vote","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"","type":"uint256"}],"name":"candidateList","outputs":[{"name":"","type":"bytes32"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[{"name":"candidateListName","type":"bytes32[]"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"}]
