Lesson 4: Final notes & Final project + repo
For this lesson, I felt it appropriate to simply develop what I already had from lesson 3. I wanted to add to the smart contract all the functionality asked in the excercises. Also I went on a little tangent, doing some testing around gas costs, which in the end was a very worthwhile excercise.
On the front end i really wanted a user balance to be a live, self updating feature, rather than it be achieved by the user having to press a button. This took me on a small journey into the useState and useEffect hooks in react.
In the end the I acheived the following:
Smart Contract
Added events and event handling to the deposit and withdraw functions
optimised the functions for cheaper gas calculation.
Front-end
Updated the style
Removed getUserBalance button
Replaced with a live bar that shows the user balance, utilizing useEffect and UseState.
