Following the completion of the design phase, we move on to the development phase.
This new system will be integrated with the old one, which has its own tracking. That the very first task was to handle the log in for two different users: those who will navigate to the Picker and those who will navigate to the Item Navigator. Mr. Peter guided me through the JWT method for solving this problem.
I first learned about JWT when I tried to make a user log into a separate navigation depending on his role. Finally, I created a token that, if the user role is Picker, navigates to the PickerNavigator; otherwise, he navigates to the ItemNavigator. And it was the first time I used the useEffect Hook that I truly grasped its concept.
After logging in, I also construct a screen for the Picker role. After hitting the button on that screen, you will be taken to the following screen. The second screen is about tables and orders data, and when you arrive there, you’ll see a table with all of the clients who have placed orders, along with their data, and the raw of each client is clickable, which will take you to another table.
