I'm about to begin working on an API, for which I plan to add GraphQL connectivity for processing data. The data processed will mainly be audio files being downloaded/uploaded with some user messaging & authentication.

I don't mind the difficulty in any service since I've used C++ (for data structures & algorithms at least) and would also say I am patient and can learn fairly quickly. My main concerns would be their performance, libraries/community, and job marketability.

Why I'm stuck between these three...

Symfony: I've programmed in PHP for back-end in a previous internship and may do so again in a few months.

Node.js: It's newer than PHP, and it's JavaScript where my front-end stack will be React and (likely) React Native.

Golang: It's newer than PHP, I've heard of its good performance, and it would be nice to learn a new (growing) language.

#rust @{#elixir}|topic:null| So am creating a messenger with voice call capabilities app which the user signs up using phone number and so at first i wanted to use Actix so i learned Rust so i thought to myself because well its first i felt its a bit immature to use actix web even though some companies are using Rust but we cant really say the full potential of Rust in a full scale app for example in Discord both Elixir and Rust are used meaning there is equal need for them but for Elixir so many companies use it from Whatsapp, Wechat, etc and this means something for Rust is not ready to go full scale we cant assume all this possibilities when it come Rust. So i decided to go the Erlang way after alot of Thinking so Do you think i made the right decision?Am 19 year programmer so i assume am not experienced as you so your answer or comment would really valuable to me

In my humble opinion the best available php platform is "API Platform". I have tried a lot of backend frameworks in the last 10 years, and that is one of the best, at least in the PHP ecosystem. It's based on Symfony, it supports plenty of features like Swagger docs, Rest API, GraphQL. You can plugin React Admin to have a full admin in no time. But the best part in my opinion it's how you can easily extend the backend taking advantage of the ORM Doctrine (which is one of the most mature available across all technologies) and all the plugins of Symfony. The fact that the Doctrine entities are in automatic relation and they can be exposed as GraphQL it's a big win if you have a complex database. It is also possible to reverse engineering an existing database and create automatically all the entities, admin, restapi, graphql endpoints ... welcome to the future :)
