node.js - How to save image path to MongoDB database

Question

I am trying to create a file upload API with some other content as well. For file upload i am using express-file-upload package . But I don't know how to save its path to MongoDB data base i tried searching but could not able to find any solution. I am new to backend development. This is my controller file.

Here is my code:

exports.createNewPost = (req, res, next) => {
  const errors = validationResult(req);
  if (!errors.isEmpty()) {
    const error = new Error("Validation failed, entered data is incorrect");
    error.statusCode = 422;
    throw error;
  }
  if (!req.files) {
    const error = new Error("No Image provided");
    error.statusCode = 422;
    throw error;
  }
  const { title, content } = req.body;
  
  console.log("reqfile", req.files);   <-- Here it does log all the image detail but i don't know how to use them
  const imageUrl = req.files.image;

  imageUrl.mv("./uploads/" + imageUrl.name);
  const post = new Post({
    title,
    content,
    imageUrl,
    creator: {
      username: "Aditya",
    },
  });
  post
    .save()
    .then((result) => {
      res.status(201).json({
        message: "Post created successfully",
        post: result,
      });
    })
    .catch((err) => {
      if (!err.statusCode) {
        err.statusCode = 500;
      }
      next(err);
    });
};

Here is my modal:

const mongoose = require("mongoose");

const Schema = mongoose.Schema;

const postSchema = new Schema(
  {
    title: {
      type: String,
      required: true,
    },
    imageUrl: {
      type: String,
    },
    content: {
      type: String,
      required: true,
    },
    creator: {
      type: Object,
      required: true,
    },
  },
  {
    timestamps: true,
  }
);
module.exports = mongoose.model("Post", postSchema);
