I make small samart contract using Remix and Ganache. I deploy it to Rinkeby test net and got problem to connect my dapp (small web site) to it. My web3 require.
window.addEventListener('load', async () => {
// Wait for loading completion to avoid race conditions with web3 injection timing.
if (window.ethereum) {
const web3 = new Web3(window.ethereum);
try {
// Request account access if needed
await window.ethereum.enable();
// Acccounts now exposed
return web3;
} catch (error) {
console.error(error);
}
}
// Legacy dapp browsers...
else if (window.web3) {
// Use Mist/MetaMask's provider.
const web3 = window.web3;
console.log('Injected web3 detected.');
return web3;
}
// Fallback to localhost; use dev console port by default...
else {
const provider = new Web3.providers.HttpProvider('http://127.0.0.1:9545');
const web3 = new Web3(provider);
console.log('No web3 instance injected, using Local web3.');
return web3;
}
});
// Initialize Web3
const Web3 = require("web3")
const web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:7545'));
//const web3 = new Web3(new Web3.providers.HttpProvider('https://rinkeby.infura.io/0xf2966f689fa2163d9b183933D1fA1Ac044B20915'));
// const web3 = new Web3(new Web3.providers.currentProvider)
// const web3 = window.web3;
web3.eth.defaultAccount = web3.eth.accounts[0]
console.log(web3.eth.defaultAccount)
// Set Contract Abi
