What are Firebase Extensions? How can they speed up your app development?
Cloud Functions are a serverless solution that allows you to run backend code in response to HTTPS requests or even more ⚡ powerfully, in response to events triggered by other Firebase products.

I made a website that puts your face on your pet, using Cloud Vision and ML. The results are absurd as they are ridiculous
Have a go at petswitch.com if you wish... I made the original Petswitch almost ten years ago, and it's had mild success since then, including CNET writing an article about it and it receiving the prestigious honour of 'most useless website' in week 41 of 2018, as determined by theuselesswebindex.com. Aside from the obvious question of why I even made this, it was getting pretty creaky – I originally built it with PHP and ImageMagick, with the facial features being manually selected via jQuery UI. So I decided to rebuild the whole thing with a full face-to-pet ML pipeline, on static hosting. To get the human face features, the app renders the upload to a temporary img element. This is a handy way to orient the image correctly via the browser, and saves having to deal with EXIF data. It's then resized, rendered to a canvas element, converted to a base64 string, then sent via fetch to Google's Cloud Vision API, which returns landmark coordinates of the face. I use these coordinates to correct any tilt on the face, mask the eyes and mouth via a mask image, then store each masked element as an additional canvas. Detecting pet faces was trickier. Google, Amazon and Microsoft all offer object detection APIs via transfer learning, and the approach is largely the same: you supply a series of images with bounding boxes around the objects you want to detect, either added via a web interface or uploaded via their API. You train a model online from these supplied images, then the service will return the estimated coordinates of any detected objects in an uploaded image. I found a dataset of both cats and dogs that had been labelled with landmarks on their faces, then wrote a script to convert the landmarks into bounding boxes around their eyes and nose, the dimensions based on a simple formula around the distance between the eyes in each image. All in all it's been trained on about 17,000 images of cats and dogs, and the accuracy seems to be pretty good. I was pleased to discover it actually works pretty well on other pets too. I've also added some friendly pets to the Petswitch family for those that don't have a pet on hand. I decided not to use a framework for this, it's written from scratch using a series of ES6 modules – although I did use Konva to handle the manual selection of facial features if the API can't detect a face. I used ParcelJS as my task runner, and my detection APIs are hosted on Firebase Cloud Functions. Let me know if you have any questions, although I can offer no good explanation for why I created this monstrosity...

How do I allow my express REST server to handle multiple concurrent requests (200-500) at the same time?
I would also consider using a serverless entry point for hook ingestion (eg Firebase Functions). That would make the hook and queue process very fast and light. It would auto scale and leave your app infrastructure largely untouched

Sending Emails with Firebase
Cloud Functions allow you to access Firebase events directly in your application. This way, you can easily integrate with the Firebase platform and accomplish a wide range of tasks.

Google Pay with Firebase extension and Adyen
Cloud Firestore is a NoSQL database part of the Firebase platform: it is designed to support complex JSON-based data structure, advanced querying and multiple languages (NodeJS, Python and Java SDKs). Firestore really stands out when used together with Cloud Functions that allow executing server-side code in response to events like changes in the database or other types of notifications.

The 2024 Web Hosting Report
Backend as a Service (BaaS) goes back to early 2010’s with companies like Parse and Firebase. These products integrated everything a backend provides to a webapp in a single, integrated package that makes it easier to get started and enables you to offload some of the devops maintenance work to someone else.

How to Do Authorization - A Decision Framework: Part 1
Google Firebase is one of the pioneers to integrate access policies into the database. It's a NoSQL data store that holds documents in collections and allows you to define security rules for object access. When making queries and mutations, Firebase checks if the request operates over objects the user can access and rejects it if it does not.

Hacktoberfest Week 4 PR
TanyaAja is an anonymous question bank platform. Once set up, you can get your own web app where others can submit questions to you. Those who post questions are authenticated via Firebase, and their questions are stored in your Notion database. It also uses Next.js and Shadcn UI. The default templates to set up the app is in Indonesian, but users are able to customize these templates to change the wordings.

Hacktoberfest Week 2 PR
To install or set up the application so that I could test my fix once ready, I had to do many things. In fact, it took me over an hour for set up, and less than ten minutes to do the fix. This is because I had to sign up for multiple services and link them all together to make it work, and the instructions were not very detailed. I had to set up Firebase for the authentication, and Notion to load the site templates as well as the database.
