My dApp have to connect to MetaMask. There are two rude solutions in the docs: make user to click connect btn every time manually or just pop up connection confirmation after page load. I want to implement the only convenient solution: first time user connect manually by clicking the connect btn and interacting with MetaMask popup and then my dApp detect that connection is still established and use this connection. I can't find the solution, but i saw this in other dApps (Capture the ether for example) I use:
import detectEthereumProvider from '@metamask/detect-provider';
const provider = await detectEthereumProvider();
if (provider) {
connect(provider)
} else {
// kind of "Install the MetaMask please!"
}
function connect(provider) {
// How to check if the connection is here
if (//connection established) {
// Show the user connected account address
} else {
// Connect
provider.request({ method: "eth_requestAccounts" })
.then // some logic
}
}
