What is NestJS?

Nest is a framework for building efficient, scalable Node.js server-side applications. It uses progressive JavaScript, is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming). Under the hood, Nest makes use of Express, but also, provides compatibility with a wide range of other libraries, like e.g. Fastify, allowing for easy use of the myriad third-party plugins which are available.
NestJS is a tool in the Frameworks (Full Stack) category of a tech stack.
NestJS is an open source tool with 63.4K GitHub stars and 7.3K GitHub forks. Here’s a link to NestJS's open source repository on GitHub

Hello everyone! I'm interested in building a Tinder-like application using NestJS with TypeScript. I'm currently exploring database options that can best support my application's needs. Can you recommend a suitable database and ORM for this type of project?

Thank you in advance for your help!

Sails.jsSails.js

We have an existing (Apis only) Rails backend, that by default follows the MVC pattern, (at peaks of 700 requests a second). I am tasked with making the same (read-heavy) application in any JavaScript framework. I was advised to follow the MVC structure. So I am considering these 3 ( Sails.js, LoopBack, NestJS). I get that sails is closest to rails, but that's not particularly a priority.

Our framework of choice for backend at Superface is NestJS. We also use AppSignal for APM and error tracking. While AppSignal provides some basic integration for Node.js, getting the monitoring to work with Nest was a bit tricky. Check out our blog post on Integrating AppSignal APM with NestJS how we made it work.

I would choose Next.js / Nuxt.js or SvelteKit as they're implemented to support the backend that manages cookies/sessions/API/reactive components and props.

The good thing about them is that if ever your app grows with a ton of traffic, you can easily migrate your SSR app and use other programming languages such as Golang or Rust to serve the API.

NestJS is only used for the backend side, however, the backend side of this is already offered from these big 3 (Next/Nuxt/SvelteKit), as these 3 major SSR Frameworks were able to connect from RDB / MongoDB / GraphQL / 3rd Party APIs, you name it!

Regarding websocket / service-worker (PWA) / wasm, those big 3 can do it too

TL;DR: NodeJS is so big, don't complicate your life, make a single route to handle the frontend and backend, migrating to performant environment such as Go/Rust can be done over an api call inside those big 3 Next/Nuxt/SvelteKit.

NestJS Alternatives & Comparisons

What are some alternatives to NestJS?
AdonisJS
It is a Node.js Framework which is highly focused on developer ergonomics, stability and confidence.
FeathersJS
Feathers is a real-time, micro-service web framework for NodeJS that gives you control over your data via RESTful resources, sockets and flexible plug-ins.
Koa
Koa aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. Through leveraging generators Koa allows you to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware.
LoopBack
A highly-extensible, open-source Node.js framework that enables you to create dynamic end-to-end REST APIs with little or no coding. Connect to multiple data sources, write business logic in Node.js, glue on top of your existing services and data, connect using JS, iOS & Android SDKs.
hapi
hapi is a simple to use configuration-centric framework with built-in support for input validation, caching, authentication, and other essential facilities for building web applications and services.
