I am using web3@0.20 inside angular to call smart contract functions,

I want to know how to watch a smart contract event in angular?

using javascript is easy and it works :

sEvent.watch(function(error, result){
        if (!error)
        } else {

I tried to use .watch and it works also in angular,


I would wrap everything inside a service and use an observable to update the component and so its UI


I think you will find the full answer to your question in this course : https://www.udemy.com/blockchain-ninja-develop-ethereum-dapp-with-angular/ but in my opinion you can start by using an Event Listener function.
