MetaMask will not appear in the browser when the transaction needs to be approved about angular-truffle-starter-dapp HOT 9 CLOSED

@Nikhil22 Sure thing. I ran into another issue with the balance binding not updating. I will fix that on Tuesday and send something through.

Using typeof window['web3'] !== 'undefined' instead of this.web3 !== 'undefined'
and using new Web3(window['web3'].currentProvider) instead of new Web3(this.web3.currentProvider) did the trick. And moving the web3 instantiating from the constructor to the hook ngAfterViewInit so that the instantiating of the web3 provider will happen after the MetaMask chrome extension is loaded (works by typing the URL in Chrome and pressing enter but does not work with a refresh (F5) or entering the same URL in the same tab again).

This is a good point, @ronh73 . The ngAfterViewInit lifecycle hook is a better use case for instantiating objects that require the view to be loaded first. I will make the changes.

Thanks, that's good to hear. In my case the number of meta's is also not directly shown (could take about 10 seconds) and after a transaction the number of Meta's does not get updated. When typing the url in a new tab in Chrome, the number of Meta's shown will be correct.

By the way, I start testrpc with the -m flag with a seed. This is the same seed (aka mnemonic) that is generated by Metamask when creating an account.

ngAfterViewInit is still to early in the page lifecycle. You have to hook the window.load event.

from angular-truffle-starter-dapp.

You can use a HostListener as follows instead of the constructor:

@HostListener('window:load')
windowLoaded() {
  this.checkAndInstantiateWeb3();
  this.onReady();
}
