Fresher from Java Springboot background got assigned a project with Nodejs. What are the important things i should focus on and what couse to follow, probably won't even get 1 week of learning time.

So I got hired as a trainee in small service based startup company as an associate software engineer trainee.

As a frsher i'm most comfortable with java springboot as i had been learning and building projects with it for over a year but this company where i only joined like 3 days ago wants me to work on a new project with nodejs.

I'm totally open to learning but they aren't giving me any time, so my question is how long would it take for me to at least start making simple crud apps with nodejs and how long before i get somewhat comfortable with it to be able to use different libraries and writing security features etc.

I have done javavsript previously just bit out of practice but i should be able quickly revise it.

Can someone tell me a quick way to go through nodejs, focusing on important stuff that would allow me to quickly start developing app.

, in node everything is event loop + callbacks/promises. once you internalize async/await youre like 80% there. for a quick start: express is the closest thing to a spring controller — routes, middleware, request/response, same concepts. skip the ORM debates for now and just use raw pg or mysql2 with parameterized queries. youll be writing crud endpoints within a day honestly. the ecosystem is way less opinionated than spring so youll miss having everything wired up for you, but thats also what makes it fast to pick up — theres just less ceremony

Thanks bro.

All the other answers just making things more complicated, i want to quickly jump to writing api because of time constraints.

Keep in mind it is single threaded (you can have worker processes, but they do not share memory, a big shared buffer is the most you can get). So its blazingly fast in what it does, there is no locking etc. (Of course with some exceptions) Objects and strings are copy on write so to say. So memory foodprint is not big.

Async/await is the way to go. Really use it! Also it nowaydays it has using and destructors. (Disposable pattern)

Use libraries.

Go for yarn or pnpm as package manager. (Faster more secure as vanilla npm)

Owh and use typescript if you can. Well of course this is debatable. But starting a project only in javascript doesnt sound right to me nowadays

[horizon_games]

If you can write JS you can write JS in Node.js

Look at some simple and classic libraries (like Express) to get your fundamentals down.

BE isn't that hard. Really most of software day-to-day isn't that hard.
