I've also created a Form to record answers at: https://forms.gle/27nxzrLMCe83uNzr7
The onboarding for other developers is also painless. I've recently experiment with AWS Amplify and even if is not quite there yet, is pretty close.
Lambda, cloudfunctions, https://supabase.com/, https://hasura.io/, AWS Amplify, https://aws.amazon.com/serverless/.
For frontend, I would go with either React or Vue, both with a huge community and already a lot of builtin solutions. I would 100% start with a design system, maybe material UI.
Nothing fancy, low maintenance and painless onboarding/development experience.
In terms of FE, it really depends on the skill-set in the team. I went for Vue over React when we had to have a bunch of backenders whip up a FE simply because it's more opinionated and we didn't want to have to make as many choices when getting started. Also, just rendering HTML on the server side can still get you a long way
For the DB, again, it depends on your use case and what your data-model looks like, but I think a relational DB like postgres is a safe choice 99% of the time. You might need to couple it with something else on occasion (I've reached for elasticsearch more times than I can count)
* If the app it's a CRM like (with lots of DB entities) I will go with Python Django, MySQL, vue.js
* For Browser apps or desktop apps that has few endpoints I will go with Golang (https://go-app.dev/) for backend and frontend.
* For a mobile app: React, the backend depends on performances, Golang or Python Django.
* IoT app (may need to process sensors data, analyze, and visualize): Golang, ClickHouse, vue.js
If it's a very simple app (e.g. a dashboard) I will be using: https://go-app.dev/ with SQLite.
- React + ViteJS for the frontend
- No backend (or Firebase functions, GCP Run, or similar)
- Firebase as the database (beats everything I know for 90%+ of projects)
- A strong design system such as TailwindCSS is a must
* Database: PostgreSQL
* Backend: Python + Django / fastAPI or Scala + Play
* Frontend: React
