2. Added mock GET students API

server.js

/*
 * Mock students
 */
const students = [
  { name: "Alice Doe", email: "alice@xyz.com", department: "Computer Science" },
  {
    name: "John Doe",
    email: "john@xyz.com",
    department: "Information Technology",
  },
  { name: "Alice Doe", email: "alice@xyz.com", department: "Computer Science" },
  {
    name: "John Doe",
    email: "john@xyz.com",
    department: "Information Technology",
  },
  { name: "Alice Doe", email: "alice@xyz.com", department: "Computer Science" },
  {
    name: "John Doe",
    email: "john@xyz.com",
    department: "Information Technology",
  },
];

/*
 * Get students with query params: [pageNumber, recordsPerPage]
 */
app.get("/api/students", (req, res) => {
  // Calculate start, Aka skip if you use it in db queries
  const start =
    parseInt(req.query.recordsPerPage) * (parseInt(req.query.pageNumber) - 1);

  // Calculate end, Aka limit if you use it in db queries
  const end = start + parseInt(req.query.recordsPerPage);

  // Send response: { count, data }
  res.status(200).json({
    count: students.length,
    data: students.slice(start, end),
  });
});
