REFACTOR OF MySQL-employee-tracker repository - link here.
This is a command line application that allows a user to manage information on employees within a company. The application connects to a database housed in MySQL that contains three tables with information on departments, roles, and employees within the company. This Content Management System allows a user to add, view, and modify information about employees of a company.
As a business owner I want to be able to view and manage the departments, roles, and employees in my company So that I can organize and plan my business
The database was initialized in MySQL Workbench after the schema files were set up (schema files included in repository). Data for employees was then seeded into the database after initialization. Upon running the program via the command line interface, a user can select to view all departments, view all roles, view all employees, add a department, add a role, add an employee, update an employee's current role, update an employee's current manager, remove an employee, remove a department, remove a role, and get the total salary for a specific department. After executing any of the add, update, or remove functions, the database is updated automatically.

MySQL Employee Management System
The below example code shows a function that queries the MySQL database and returns information on all employees when invoked:
viewAllDepartments = () => {
connection.query(`SELECT * FROM department ORDER BY department_id ASC;`, (err, res) => {
if (err) throw err;
console.table('\n', res, '\n');
startApp();
})
};The below example code shows a function that allows a user to add a role into the MySQL database when invoked:
addARole = () => {
connection.query(`SELECT * FROM department;`, (err, res) => {
let departments = res.map(department => ({name: department.department_name, value: department.department_id }));
inquirer.prompt([
{
name: 'title',
type: 'input',
message: 'What is the name of the role you want to add?'
},
{
name: 'salary',
type: 'input',
message: 'What is the salary of the role you want to add?'
},
{
name: 'deptName',
type: 'rawlist',
message: 'Which department do you want to add the new role to?',
choices: departments
},
]).then((response) => {
connection.query(`INSERT INTO role SET ?`,
{
title: response.title,
salary: response.salary,
department_id: response.deptName,
},
(err, res) => {
if (err) throw err;
console.log(`\n ${response.title} successfully added to database! \n`);
startApp();
})
})
})
};The below example code shows a function that allows a user to remove an employee from the MySQL database when invoked:
removeAnEmployee = () => {
connection.query(`SELECT * FROM employee ORDER BY employee_id ASC;`, (err, res) => {
if (err) throw err;
let employees = res.map(employee => ({name: employee.first_name + ' ' + employee.last_name, value: employee.employee_id }));
inquirer.prompt([
{
name: 'employee',
type: 'rawlist',
message: 'Which employee would you like to remove?',
choices: employees
},
]).then((response) => {
connection.query(`DELETE FROM employee WHERE ?`,
[
{
employee_id: response.employee,
},
],
(err, res) => {
if (err) throw err;
console.log(`\n Successfully removed the employee from the database! \n`);
startApp();
})
})
})
