Question

Leverage Firebase cloud functions to transmit a POST request to a server that is not affiliated with

Is it feasible to utilize a firebase cloud function for sending a post request to a non-Google server? It appears that being on the blaze plan is necessary in order to communicate with non-google servers.

Essentially, I aim to perform a POST action to an external server operating on an arduino whenever a new value is added to my database.

I have gone through the documentation and come across examples of cloud functions responding to an HTTP post request (HTTP cloud functions); however, I am unable to locate any instances of posting to an external server. Can this be done?

Important: The request package is no longer supported, as indicated on the npm page request-npm. It's recommended to explore other alternatives like axios

You can achieve this by utilizing the request module:

// Importing the module
var request = require('request');

// Making the request
request('put your external URL here', function (error, response, body) {
    if (!error && response.statusCode == 200) {
        // Add your desired actions for handling the request here
    }
})

NOTE: This method will only function with premium plans. Utilizing non-Google APIs is not feasible with the free Spark plan, as detailed in the Firebase pricing guidelines:

The Spark plan permits outbound network requests solely to Google-owned services. Inbound invocation requests fall within the quota limits. On the Blaze plan, Cloud Functions offer a perpetual free tier. The initial 2,000,000 invocations, 400,000 GB-sec, 200,000 CPU-sec, and 5GB of Internet egress traffic are provided at no cost each month. Charges apply for usage exceeding this complimentary allotment. Pricing is determined by the total number of invocations and compute time. Compute time varies based on the allocated memory and CPU for a function. Usage restrictions are enforced through daily and 100s quotas. For further details, refer to Cloud Functions Pricing.

If you are looking to make a post request with a JSON body, here is a helpful function that can assist you. (I wish I had known about this sooner)

export function sendPostRequestWithJsonBody(url: string, body: any): Promise<ReqResponse> {

  const request = require('request');

  const options = {
    url: url,
    json: true
  };
  return new Promise(function (resolve, reject) {
    request(options, function (error, response) {
      if (error) {
        console.log(error);
        reject({ error: error });
      }
      resolve(body);
    });
