ASSIGNMENT: create a phonebook API which will enable a user to save a persons details edit and delete also assign a person to a certain group. persons details include full name, mobile number ,work number, email, home address and group id

looking at our file structure we created one file named src to carry all the api's logic which include the controllers and routes.

Before using the API create this: CREATE DATABASE phoneBook;

create table groups (id int primary key, GroupName varchar(20), Descriptions varchar(20) );

create table Contacts (id int primary key, fullName varchar(100), email varchar(255), mobileNo varchar(20), workNo varchar(20), address varchar(20), groupId int,

FOREIGN KEY(groupId) REFERENCES groups(id) );

//Sample data for group and contact tables

INSERT INTO groups (id, GroupName, Descriptions) VALUES (1, 'Group 1', 'Description 1'), (2, 'Group 2', 'Description 2'), (3, 'Group 3', 'Description 3'), (4, 'Group 4', 'Description 4'), (5, 'Group 5', 'Description 5'), (6, 'Group 6', 'Description 6'), (7, 'Group 7', 'Description 7'), (8, 'Group 8', 'Description 8'), (9, 'Group 9', 'Description 9'), (10, 'Group 10', 'Description 10');
