Using mongoose style schemas MSSQL in Node.js

Question

I am currently writing an API with Express.js and have seen many examples about how to create schemas/models for mongodb, but was wondering if there is any similar solution for MSSQL. For example, I have the following method in a C# controller:

public void SubmitExpenses(List<Expense> expenses)
        {
            using (cnxn)
            {
                cnxn.Open();
                for (int i = 0; i < expenses.Count; i++)
                {
                    int employeeId = expenses.ElementAt(i).employeeId;
                    string expenseDate = expenses.ElementAt(i).expenseDate;
                    int taskId = expenses.ElementAt(i).taskId;
                    int expenseTypeId = expenses.ElementAt(i).expenseTypeId;
                    int billingCategory = expenses.ElementAt(i).billingCategory;
                    string notes = expenses.ElementAt(i).notes;
                    float amount = expenses.ElementAt(i).amount;
                    string lastUpdatedDate = expenses.ElementAt(i).LastUpdatedDate;
                    int lastUpdatedBy = expenses.ElementAt(i).LastUpdatedBy;
                    string dateSubmitted = expenses.ElementAt(i).dateSubmitted;


                    //public void SubmitExpenses(int employeeId, string expenseDate, int taskId, int expenseTypeId, int billingCategory,
                    //    string notes, float amount, string lastUpdatedDate, int lastUpdatedBy, string dateSubmitted)
                    //{

                    using (SqlCommand sqlQuery = new SqlCommand("INSERT INTO Expenses " +
                        "(Employee_ID, Task_ID, Expense_Date, Expense_Type_ID, Billing_Category_ID, " +
                        "Amount, Notes, Last_Updated_By, Last_Update_Datetime, Date_Submitted, Location) " +
                        "Values (@employeeId, @taskId, @expenseDate, @expenseTypeId, @billingCategory, @amount, @notes, " +
                        "@lastUpdatedBy, @lastUpdatedDate, @dateSubmitted, @locationId)", cnxn))
                    {
                        sqlQuery.Parameters.Add(new SqlParameter("@employeeId", SqlDbType.Int) { Value = employeeId });
                        sqlQuery.Parameters.Add(new SqlParameter("@expenseDate", SqlDbType.DateTime) { Value = expenseDate });
                        sqlQuery.Parameters.Add(new SqlParameter("@taskId", SqlDbType.Int) { Value = taskId });
                        sqlQuery.Parameters.Add(new SqlParameter("@expenseTypeId", SqlDbType.Int) { Value = expenseTypeId });
                        sqlQuery.Parameters.Add(new SqlParameter("@billingCategory", SqlDbType.Int) { Value = billingCategory });
                        sqlQuery.Parameters.Add(new SqlParameter("@notes", SqlDbType.Text) { Value = notes });
                        sqlQuery.Parameters.Add(new SqlParameter("@amount", SqlDbType.Money) { Value = amount });
                        sqlQuery.Parameters.Add(new SqlParameter("@lastUpdatedDate", SqlDbType.DateTime) { Value = lastUpdatedDate });
                        sqlQuery.Parameters.Add(new SqlParameter("@lastUpdatedBy", SqlDbType.Int) { Value = lastUpdatedBy });
                        sqlQuery.Parameters.Add(new SqlParameter("@dateSubmitted", SqlDbType.DateTime) { Value = dateSubmitted });
                        sqlQuery.Parameters.Add(new SqlParameter("@locationId", SqlDbType.VarChar) { Value = "" });

                        sqlQuery.ExecuteNonQuery();
                    }
                }
            }
        }

And the Expense.cs model:

public class Expense
    {
        public int employeeId { get; set; }
        public string expenseDate { get; set; }
        public int taskId { get; set; }
        public int expenseTypeId { get; set; }
        public int billingCategory { get; set; }
        public string notes { get; set; }
        public float amount { get; set; }
        public string LastUpdatedDate { get; set; }
        public int LastUpdatedBy { get; set; }
        public string dateSubmitted { get; set; }
        public string location { get; set; }
    }

How would I go about in similar fashion in Express.js so I could take a list of JavaScript objects, break them into elements which could then be parameterized and submitted?

Would it be something like...

app.post('/route/to/api', function (req, res) {
    var sql = require('mssql');

    sql.connect("mssql://user:password@localhost/Northwind").then(function () {
        console.log('connected');



       for (var i = 0; i < req.length; i++) {
            new sql.Request()
                .input('input_param', sql.VARCHAR, req[i]['PropertyName'])
                .query('INSERT INTO Table VALUES (@input_param)')
                .then(function (recordset) {
                    console.log(recordset);
                })
                .catch(function (err) {
                    console.log(err);
                });
        }
    }).catch(function (err) {
        console.log(err);
    });
});

Any advice would be much appreciated!

Have a look at sequelize . It should give you the functionality you require.
