Install the node cron package

npm install node-cron

Code to Shedule Deletion

const cron = require("node-cron");
const User = require("../models/User"); // Assume `User` is your Mongoose model

exports.deleteProfile = async (req,res) => {
  try{
   const {userId} = req.body;
   //validate input
   if(!userId){
      return res.status(400).json({success:false,  message: "User ID is required" });
}
 // Find user to ensure existence

const user = await User.findById(userId);
if (!user) {
      return res.status(404).json({ success: false, message: "User not found" });
    }

 // Schedule deletion after 5 days

const deletionDate = new Date();
deletionDate.setDate(deletionDate.getDate()+5);

cron.schedule(deletionDate.toISOString(), async () => {
      await User.findByIdAndDelete(userId);
      console.log(`User with ID ${userId} deleted successfully.`);
    });

    return res.status(200).json({
      success: true,
      message: `User deletion scheduled for ${deletionDate.toISOString()}`,
    });


}
catch(error){
   console.error("Error scheduling deletion:", error);
    return res.status(500).json({ success: false, message: "Internal Server Error" });
}

How to shedule a task in Node.js using Node Cron

__To handle a delayed deletion request (e.g., deleting a user profile after 5 days), you can achieve this in Node.js using a delayed task scheduling approach. Here’s a step-by-step implementation:

Approach 1: Using a Background Task Scheduler (e.g., node-cron or Agenda.js)
Example with node-cron:

Install the package: npm install node-cron Code to Shedule Deletion const cron = require("node-cron"); const User = require("../models/User"); // Assume User is your Mongoose model

exports.deleteProfile = async (req, res) => {
try {
const { userId } = req.body;

// Validate input
if (!userId) {
  return res.status(400).json({ success: false, message: "User ID is required" });
}

// Find user to ensure existence
const user = await User.findById(userId);
if (!user) {
  return res.status(404).json({ success: false, message: "User not found" });
}

// Schedule deletion after 5 days
const deletionDate = new Date();
deletionDate.setDate(deletionDate.getDate() + 5);

cron.schedule(deletionDate.toISOString(), async () => {
  await User.findByIdAndDelete(userId);
  console.log(`User with ID ${userId} deleted successfully.`);
});

return res.status(200).json({
  success: true,
  message: `User deletion scheduled for ${deletionDate.toISOString()}`,
});

} catch (error) {
console.error("Error scheduling deletion:", error);
return res.status(500).json({ success: false, message: "Internal Server Error" });
}
};
