Node.js mssql data input layer with connection pool - sql-server

Question

This question relates to a Node.js mssql API.
I've recently updated my code to use a SQL.ConnectionPool instead of sql.connect which when combined with an async / await function allowed me to get around connection.close() errors.
In my previous (OLD) executeQuery function, I was able to pass an array which I could push values into to use with "request.input(name, value)"
Function call example:
app.get('/api/route/:id', function (req, res) {
var id = req.params.id;
let x = []
if (id != null && id != NaN) {
x.push({
Name: 'id', Value: id
})
var query = `SELECT * from [Table] where ID = #id`
executeQuery(res, query, arr);
} else {
res.send(500)
}
})
OLD Function:
var executeQuery = function (res, query, arr) {
sql.connect(dbConfig, function (err) {
if (err) {
console.log('Error while connecting to the database: ' + err)
res.send(err)
} else {
// Create the request object
var request = new sql.Request();
if (arr != null) {
if (arr.length > 0) {
for (var obj of arr) {
request.input(obj.Name, obj.Value)
}
}
}
request.query(query, function (err, rs) {
if (err) {
sql.close();
console.log('Error while querying the database : ' + err);
res.send(err);
} else {
sql.close();
console.log(rs)
res.send(rs)
}
})
}
})
}
NEW Function:
var executeQuery = async function(res, query, arr){
const pool = new sql.ConnectionPool(dbConfig);
pool.on('error', err => {
console.log('sql errors ', err);
});
try {
await pool.connect();
let result = await pool.request().query(query);
console.log('success')
res.send(result);
return {success: result};
} catch (err) {
console.log('error')
console.log(err)
res.send(err);
return {err: err};
} finally {
pool.close();
}
}
Question
How do I go about achieving the same request.input process with a ConnectionPool as I did with my previous function ( like the below )
var request = new sql.Request();
if (arr != null) {
if (arr.length > 0) {
for (var obj of arr) {
request.input(obj.Name, obj.Value)
}
}
}
Thank you.
