Mongodb – How to Declare mongo models from different files with TypeScript

I have the following structure in my Node.js TypeScript project:

The important part here is the mongoModels. I have 2 models and they are connected as each Category model has field category.expertUserIds which contains array of user._id.

user.ts:

const { Schema, model } = require("mongoose");

const userSchema = new Schema({
  username: {
    type: String,
    require: true,
  },
  password: {
    type: String,
    require: true,
  },
});

module.exports = model("User", userSchema);

category.ts:

const { Schema, model } = require("mongoose");

const categorySchema = new Schema({
  name: {
    type: String,
    require: true,
  },
  description: {
    type: String,
  },
  expertUserIds: [
    {
      type: Schema.Types.ObjectId,
      ref: "User",
    },
  ],
});

module.exports = model("Category", categorySchema);

I have many project on exactly the same concept created as regular .js files but when I use TypeScript it is giving me this error:

mongoModels/category.ts:1:17 – error TS2451: Cannot redeclare
block-scoped variable ‘model’.

1 const { Schema, model } = require("mongoose");
~~~~~

Same is for Schema and for both files. So basically it counts that I declared already:

const { Schema, model } = require("mongoose");

once and I cannot do it again for other file. How is that an error and how I can fix it as I am invoking Schema and model in different files?
