What is the best way to establish and maintain lasting connections with the Firebase database while utilizing the superagent

Currently, I am following the Firebase Functions documentation on enhancing Firebase database performance.

I have provided the code snippet below for your reference.


const request = require('superagent');
const functions = require('firebase-functions');

exports.function = functions.https.onRequest((request, response) => {
    request
        .get('<URL>')
        .end((err, response) => {
            res.status(200).send(`Data: ${response.text}`);
    });
});

Following the instructions from the link, I aim to maintain persistent connections to the database. However, I am facing a challenge in determining the URL beforehand while using the superagent package within the function.

Being relatively new to functions, I usually receive the URL after completing the function deployment process.

If anyone could guide me on effectively utilizing the superagent package with Firebase Functions, it would be greatly appreciated.

Unfortunately, the code provided in the Firebase documentation is not accurate. However, it should align with the equivalent Cloud documentation that demonstrates the usage of superagent. Once you adapt it to utilize the Firebase SDK, the revised code will resemble the following:

const request = require('superagent');
const https = require('https');
const keepAliveAgent = new https.Agent({ keepAlive: true });

exports.function = functions.https.onRequest((req, res) => {
    request
        .get('<URL>')
        .agent(keepAliveAgent)
        .end((err, response) => {
            res.status(200).send(`Data: ${response.text}`);
    });
};
