Any tools that achieve your software functionalities is good. you should check if with these frameworks you can do video-call, chat etc. how the scalability is achieved and the complexity of using it with them. since you are starting from scratch you can do this kind of feasibility before starting

If I want to write server api, I will use NestJS as primary framework. It base on express | fastify so I can use anything of expressJs. SpringBoot is a java framework. I will think to write as payment transaction service. If you are Ionic developer. you will know Js / ES6. You can try NestJS / ExpressJS. - video calling: You can not create video calling feature. Some keywords: ffmpeg / coturn / webrtc - chatting: realtime (socket.io / websocket) - you can try some opensource as rocketchat. It also have video calling feature.

You can use NestJs with microservice architecture.where you can also use socket.io for web socket. you can use MongoDB (For real-time data) & MySQL for customer management.if you don't want to implement websocket.you can use firebase.it gives realtime database & firestore.which can handle millions of connections and scale it up.

I would also go with NestJS. I would say Java is unnecessarily complicated and limited. And Python is not typed. TypeScript is powerful and typed and goes well with NestJS, especially using RxJS.

Django does not enforce backend-frontend separation, which probably was a good thing back in the days, but not anymore. But on the other hand enforces the project structure to you, which I don't like.

Just a simple Node.JS app with templating engine for UI can be sufficient for what you want to achieve.

Spring boot with Spring Security[JWT], Websocket, Thymeleaf or Mustache, and styling with Bootstrap.

NestJS is an excellent framework (they both are). I would say the fact that you're working with Angular makes NestJS a great match, unless you're splitting front and back end between developers. But even in that case I would still go with NestJS for a new project.

Regarding the single threading point, take a look at PM2 which helps to run Node in multiple processes (we use it with NestJS) https://pm2.keymetrics.io/docs/usage/cluster-mode/

Also regarding web server performance in general this is an interesting post showing how Node with outperform Java in a web situation (be careful though, best to check a few posts to make sure these aren't totally biased benchmarks!): https://www.tandemseven.com/blog/performance-java-vs-node/

Node.js has only 1 real thread per process; Java JIT will mostly run faster than JS one; So if it happens to be not only I/O... Why do you need most popular, not simply popular? Does Node.js have tech advantages?

I highly recommend NestJS because:

• It's a framework you already like;
• Typescript is growing fast, being increasingly adopted in the community;
• All layers are well defined, not needing to think much about the organization;
• Great documentation;
• Nest CLI increases the development speed and keep the pattern;

Only using express and knowing that project can grow, you'ill need to define the structure well so that it doesn't get out of control.

Hi Louai,

I am quite sure that you know the answer to your problem. And I am here to help you to follow your arrow. I have worked with the most popular Nodejs frameworks and I can sure you that there's no stack better than NestJS (at all). Typescript is the best thing that happened with Javascript, this is a fact. Ans NestJS make a such wonderful job using all the best Typescript tools. NestJS is the most mature and organized API manager. Its modular dependence injection, the use of DDD, the solid idea of single responsibility, it's unit a and e2e testing support, its documentation is the most incredible work in the world of Nodejs. You won't regret choosing this framework, even if your application grows a lot. If you follow the documentation tips you will be able to create an amazing and organized application.

ps: I am not part of the NestJS team, I am just a guy tired of wasting time with dumb and bad Frameworks and its bad documentations. I find relief in NestJS with all the time it's saved to me, it helped me to improve my job and let me create great things with Nodejs.

I would definitely suggest NestJs over other options because NestJs gives a lot of tooling. it would definitely suggest NestJs over other options because NestJs gives a lot of tooling & it gives a lot of functionality out of the box. If your team worked with angular 2+ then it will really easy to learn.

First of all, my experience using either Node.js with Express or NestJS is not wide. I liked NestJS due to it's similarity to Angular, so when you know Angluar and like TypeScript you are going to love NestJS, it will be instantly very familiar and easy to use, it's adds a good structure to the project out of the box and well, it uses TypeScript, which is a more structured language - it's good for scalability. As for performance concern s - NestJS is based on Node, it just brings Angular's modular structure to it, so the question is more about how is the additional layer influences the performance - I cannot answer that.

Hi, I'm in a similar position, but related to personal projects. After falling in love with few frameworks in the first day and rejecting them in day 2, I started learning nestJS last week. I currently develop personal side projects using cakephp, and I intend to migrate to nest + vue. This week I'm taking a nestJS course in order to be sure that this is what I want by praticing a little. If you didn't do it yet, I suggest you try to code a todo app or a similar example API using nest, so you can "feel" if this is indeed what you want to use in this larger-scale project.

Some of the characteristics that got my attention to nestJS are typescript, a lot of annotations/decorations, an oppinionated approach to organizing the project, nice documentation and discord, and it's evolution at npm trends shows me it's probably not going to vanish or get buggy anytime soon.

Have you checked out Hapi as an alternative? I'ts not Typescript by default though. If that doesn't seem too interesting, it sounds like you want to go with NestJS :)
