How to export a Mongoose model from a CommonJS module in TypeScript NodeJS app

I have a model defined in models/user.ts

import mongoose = require('mongoose');
var userSchema = new mongoose.Schema({ ... });
var User : mongoose.Model<any> = mongoose.model("User", userSchema);

Normally in JavaScript, in order to use the model User in a NodeJS app app.js,

In JavaScript I would ordinarily use module.exports = User from ./models/user.js, followed by require from the file I want to use User from.

e.g.

var user = require('./models/user')

however this is not recognized in TypeScript (I get transpiler errors), and neither is

import User = require("/models/User")

although that would work if I was exporting, say a class, from /models/user.ts like

export class User { ... }

What is the syntax to export the mongoose model from ./models/user.ts and import it from another file?

Export

import mongoose = require('mongoose');
var userSchema = new mongoose.Schema({ ... });
var User : mongoose.Model<any> = mongoose.model("User", userSchema);
export = User;  // EXPORT

Export Non Type Script

import mongoose = require('mongoose');
var userSchema = new mongoose.Schema({ ... });
var User = mongoose.model("User", userSchema);
export default { User };  // EXPORT

Import

import User = require("./models/User"); // Note the `.` to make it relative.

You want to simply prepend export to your model. 

import mongoose from 'mongoose';
var userSchema = new mongoose.Schema({ ... });
export default var User : mongoose.Model<any> = mongoose.model("User", userSchema);

Or if you want to stick with the CommonJS syntax you can export.modules = User;
