Usage

/**
instance the class and pass the database config to the constructor 
you can declare this constant in the main file of your project and export it to use it in other files
**/
// filename: index.js
const rest = new (require('rest-mssql-nodejs'))({
    user: 'db_username',
    password: 'db_password',
    server: 'localhost', // replace this with your IP Server
    database: 'db_name',
    port: 1433, // this is optional, by default takes the port 1433
    options: { 
        encrypt: true // this is optional, by default is false
    } 
});

module.exports = {
    rest
}

// filename: controller.js
const { rest } = require('../../index.js');

// how to execute a query without parameters
const result = await rest.executeQuery(
    'select * from your_table'
);

// how to execute a query with parameters
const result = await rest.executeQuery(
`
    select 
        *
    from your_table 
    where (
        @id = 0 or id_id = @id
    )
    `,
    [{
        name: 'id',
        type: 'Int',
        value: 1
    }]
);

// print the result
console.log("QUERY RESULT: ", result.data);
//----------

// how to execute a stored procedure without parameters
const result = await rest.executeStoredProcedure('spName');

// how to execute a stored procedure with parameters
const result = await rest.executeStoredProcedure('spName', null, {
