Calling a stored procedure with sequelize and an express API - node.js

Question

This is probably pretty easy but I've been unable to piece it together properly.
I'm trying to use the Sequelize NPM to call a stored procedure that I built and then I want to trigger it with a GET request from from an express api and return the output of the procedure to the api.
Here is what my code looks like for the Sequelize portion....
// Testing stored procedure //
const Retrieve = (testName) => connection.testdata_connection.query("EXEC [SPROC] [INPUTS]")
module.exports = {
tests: Tests(),
retrieve: Retrieve()
};
This part "connection.testdata_connection" is just establishing my connection to the database and I have tested this and I know this part is set.
I would like to be able to hit that with something like...
const query = require('./database/queries'); ///Imports sequelize queries
const app = express();
app.get('/decrypt', function(req,res){
query.retrieve()
})
})
This doesn't work at all.
Now if I do something like this in the queries file...
const Retrieve = async function() {
const decrypt = await connection.testdata_connection.query("EXEC [SPROC] [INPUT]")
console.log(decrypt)
}
module.exports = {
tests: Tests(),
retrieve: Retrieve()
};
This will log to my console with correct data when I start the server. I want it to do that when I hit it with my endpoint.

First, your function should be exported but not executed:
// creating an async function (all i/o operations should be async).
const Retrieve = async(testName) => connection.testdata_connection.query("EXEC [SPROC] [INPUTS]")
module.exports = {
retrieve: Retrieve,
// retrieve: Retrieve() if you call the function with (), the function will be executed and we don't want that yet
};
Now we can call it in the route:
const query = require('./database/queries'); ///Imports sequelize queries
const app = express();
// the route is async because it is executing async code
app.get('/decrypt', async (req,res) => {
// waiting for the answer with await
const response = await query.retrieve();
// Doing something with the response
})
You still need to check for errors, but that is the basics.
