I think you should first choose either a database or server side programming language then you can streamline your other choices based on that, but I think if you are building a big project then going with django + firebase / mongodb would be a good choice else choose laravel + firebase.

PhP might be old fashionned but Laravel is really great. I've tried nodeJs backend with express, python with flask and a little bit of serverless, and quite frankly, laravel was by far the best in my opinion. It has a lot of official packages that speeds up development (from authentification to serverless deployement), it also uses Eloquent ORM that support Mysql databases. Finally it works great with VueJs for the front end development.

I recommend ExpressJS or NestJS as BackEnd and React as Front-End and PostgreSQL as the database. The reason is as follows. First of all, since it is a financial system, various services will exist, and each service must be well connected and combined with each other. The organic combination of small services that work very well is the foundation of a great system. For this, it is best to use Node.js based, and I think ExpressJS or NestJS is the best choice. We recommend choosing React or Vue as the FrontEnd. PostgreSQL is currently the best performing database. These three combinations have many examples, and their superiority has been confirmed by my implementation in many projects already. If you are interested in my advice and have any questions, please feel free to contact me.

On my end for me it's better to choose Laravel. It has very good documentation and easy to code. The framework supports MVC and you can create either monolithic or API only. The community is also big. If you combined a Domain Driven Development (DDD) and Test Driven Development (TDD) on Laravel then it will be a superb.

Since you are using PHP more natural is Python - it can handle high traffic - Python is very effective in coding. Python is superset of Java and C++ - True Object Oriented and have very clear syntax (Spring is hard to learn and debug - you can be confused many times). It is human readable you can code 2-4 times faster with small speed sacrifice. Jinja2 is more faster/flexible Django - whatever Django is better with ORM. Flask is just proposal - many other options of web servers.

Moving from Rails will reduce development velocity (if you want to have easy support and update the app) and will require more skilled (expensive) developers to support it.

Without previous experience (5+ years) do not suggest moving to node.js. That code will easily become hard to learn and support.

You always can implement microservices with Ruby, but this approach should be considered only after Series-A and when you will have more than 5 developers and dedicated SRE/DevOps.

I see it's been some time since this was posted, but I'm glad you are migrating to Next.js 🎉!

Me personally, I would run an Express.js backend so that frontend and backend logics don't feel blurred, especially if you want to attract more developers to your project. Keeping frontend separated from the backend makes for a healthier workspace ecosystem and often confuses people less. Furthermore, implementation is a lot easier and later on as you move from RoR to an Express.js server there won't be too much confusion as to how certain parts mesh together.

Based on the features you're looking at I would consider using websockets (WSS or Socket.IO) for the chat application or rolling that with features from WebRTC, which you would need to support video streaming anyways. For authentication you could look at Auth0 which has some very nice libs for authentication or you could rig up your own stitching individual OAuths (Google, Facebook, etc.) along with a simple User/Pass signup that you manage in your database. For payment I would consider using Stripe, it's very popular in the JS ecosystem right now, has lots of documentation and features, and is also pretty cost-effective.

I know it's been some time since you have posted this and you have already made some decisions, but if you (or anyone else reading this) has any question feel free to let me know :)

If you are already committed to Python for the data analysis then it would make sense to use Django for the framework and stick with Python throughout. In general the fewer technologies you use (unless there is real justification) will improve process and long term costs.

All things being equal the fact you would not have less (likely no) licensing costs with a Python based solution will overall reduce your long term costs.

If you will be doing data analysis and complex algorithms Django is best suited for this because of it' maturity and the huge communities providing lots of Python libraries for data analysis and more.

The most relevant part is the central architecture more than the specific backend. For me, it makes sense to go for an event-driven solution. In this case, an event is emitted on every new data, and one or more listeners react to it. In AWS, you can easily get this by storing your data in DynamoDB, which is pretty fast, and have as many lambdas working on the received data (here you can find more details). This way, you keep your worker(s) busy fetching data while others consolidate it. I wouldn't get too crazy on the lambdas, and I'd start with one as there will be only one client by your description. My only concern is how similar the APIs you're consuming are. Depending on that, it may be easier to have different lambdas by target API. My only note on the backend language is that if you want low latency, I'd discard Python and Ruby and choose Go (I know that is not in the list, but given that you're open to learning a new language, you could give it a try). It is easy to learn, has excellent performance, and is the only Lamdba runtime with an X (1.X) in the supported language, making it a great choice.

If you already have some knowledge in C# you can go with ASP.NET Core MVC and continue your learning path (if you liked the language in the first place). but both solution will allow you to build an ERP/eCommerce project.

There is not too much difference between Django and ASP.Net Core MVC both follow the same design principles for building application, they both flexible, provide a lot of library, have a great community support..

The downside (thats my opinion) with ASP.Net Core you are going to follow the Microsoft philosophy of doing thing and you will mostly by tight to there products lineup. Instead of Django where you'll have more freedom.

If your concern is - Robustness: both are valid choice - Long Term Support: Go ASP.Net why? Because the project is maintained by Microsoft the chance that the project go unmaintained is low. Django is more Open Source we never know when it will stop be maintained.

The best I can give you, it's to try both and make your own opinion. Build a Proof of Concept and see by yourself.

If you are starting from scratch, I would recommend Express.js as a backend web framework. It is faster and more flexible than Django. Express makes it easy to build web applications offering numerous benefits such as efficiency and quicker development times. Some features that are worth mentioning: middlewares, templating, routing, and debugging.

The most important element that is missing the stack is the database. A Web-Based ERP/Accounting Software require a powerful Relational Database to comply with ACID princliples (Atomicity, Consistency, Isolation and Durability). By atomicity, we mean that that database is able to perform the transactions in an atomic manner. A transaction is just a single unit of work, which can either be one query, or multiple queries. Let's say that we have two accounts. And we need to transfer $100 from account one to account two. Now this transfer is just one transaction, but it is going to consist of three different steps. The first step is checking if the account one does have $100. The second would be upgrading the amount of account one to be $900. And the third would be taking this $100 and making the balance and account two be $200. If the database does support atomic transactions, if one of these three steps fail, the whole transaction should fail. This is what atomicity is.

Consistency means that the database should help in achieving the correct data state, adding certain constraints. We can add a constraint on the amount column that it can never be negative, and the database must make sure that this constraint must always be followed.

Then, we have isolation, which is mainly about the concurrency control. Let's say that we have an account which has $1,000, and there are two persons A and B trying to get the money out of this account. So $1,000 and $100. If we let both of these transaction happen at the same time, this would result in the reduction of $1,100. So the balance will result in the negative $100. Isolation prevents this to happen.

Finally, durability means that once a transaction is committed, the data must be written to the non volatile memory or the storage. So that even if the crash happens or something wrong happens with the database, the data must be there and not be corrupted.

In terms of relational database my recomendation is using Postgres. Postgres is an object-relational database, while MySQL is a purely relational database. This means that Postgres includes features like table inheritance and function overloading. Postgres also adheres more closely to SQL standards.

I found that Python-Django is the most powerful platform/framework to build any kind of application. It's not. Even you change "Python-Django" to something else, it still will not be a valid statement. Each tool/service/language/framework has advantages and disadvantages and should be considered in each case separately.

Next, Python is a scripting language, C# is a typed one. For serious projects in most cases typed languages are the better choice.

Finally, if you have some .NET experience, ASP.NET Core looks obvious choice.

ASP.NET will work better in a windows environment. Django probably works better in a Unix environment. I feel like there are a lot more hosting options for Django on Unix (digitalocean, Heroku, Linode, AWS, ...).

So, I think Django.

However, I like Unix and python better, so I'm biased.

Globally, Spring Boot is more demanded than Django. For example, there are about ten times more open positions for Spring Boot than for Django in Brussels. So this naturally drives up the price of developers mastering Spring Boot. If you have an opportunity to work with Spring Boot, I suggest you take it, as it is a sound career decision. Furthermore, your experience with Django will help you to master Spring Boot, as both frameworks share many concepts. That said, Django positions do also exist, and it's absolutely not a bad decision to become an expert with that framework either. Django developers seem to like it very much.

My mantra is not sticking to a particular technology. That is what I'd suggest. Going by that, I recommend you learn both, Django and Spring Boot. But if you want to choose one among the two, I'd say stick with Django. Saves you the effort of learning a new language and a new framework. Rather, you can spend that time honing your Django skills. It is a wrong notion among young graduates that organizations decide pay based on your technology stack. You just need to be good at a technology that is in demand. You'd be paid well no matter the technology. Django is a wonderful framework and there are tons of companies looking for Django experts. The same can be said about Spring Boot. Both are wonderful technologies in their own accord. As for you, just go with the technology you are already familiar with. It is a misconception that Spring Boot developers get paid better than Django developers.

Learn both. Spring boot takes more time to learn, because you need to understand spring core first, then spring MVC, then build tools like maven, pom (to truly master spring boot application deployment) One specific technology is never going to land you a job. Go for the whole stack. Example, organizations that use spring boot, won't just look for candidates with spring boot. They might ask for docker, Kubernetes, JavaScript, some ui framework like angular/react, maven, git, etc. Learning curve for python django is easy and small. Focus one technology at a time. Learn it in a couple of weeks. Then go on to another technology in the stack. If you master multiple stacks say java stack, data science stack, web development stack then you should not be short of opportunities. More opportunities means more bargaining power. Having said that, don't run behind money. Money is necessary to sustain but it is not worth pursuing. Pursue moral values, or at least technical excellence. And money will follow wherever you go.

Hey there 👋,

Daniel from the Prisma team here.

I think your choice of a stack would work well for your final year project.

Some recommendations: - Use PostgreSQL if you need a stable stack. Prisma support for MongoDB is currently in Preview and therefore isn't stable. Moreover, PostgreSQL being a relational database enforces a schema more strictly than MongoDB which is useful given that your data model involves multiple relations. - If your Django backend exposes a REST API, you can also expose it over the GraphQL API by proxying requests from the GraphQL API to the REST API. That way, you have a unified API for all operations. This is typically known as wrapping. - Regarding the GraphQL part, I would consider looking at Nexus and nexus-prisma.

For inspiration, check out the Prisma Examples ​repository which contains many ready-to-run examples.

Here's another fully-fledged example using Prisma, Fastify, GraphQL, and PostgreSQL: https://github.com/2color/fastify-graphql-nexus-prisma

Hi. Maybe you can try use FastAPI instead Django https://fastapi.tiangolo.com It could be faster. The FastAPI documentation is so useful and elegant.

Also you can try split a little more the backend and use an "microservice" architecture. Using Kubernetes to deploy your services.

Try to do it with less - Nodejs + Redis + socket.io, optionally you can always communicate with django, but you can do it all in Nodejs, use pm2 and cluster too. For Redis you can also use Pub/Sub, is a good combination for future scaling.

Comparing them end-to-end, Rails comes the most productive in my opinion. But there are bolder parameters you may consider. i.e. no one switches from Django to Rails to improve productivity and vice versa (probably from Laravel to one of those two).

• The language's productivity also matters, which both Ruby and Python are better for that.

• There is a philosophical difference between #Django and #Rails :

• Django supports the "Explicit over Implicit" idea, making it easier for newcomers to understand what's going on. This idea also has downsides. This allows beginners to start working with Django without even learning Django and best practices and defer learning by using references like Stackoverflow.com, which is not a good idea because you potentially don't know things that you don't know! Also, you may find many different project styles.

• On the other hand, Rails support the "Convention over configuration" and Scaffolding idea. It's easier for a Rails developer to be added to a new project or just review a random Rails project. Everything has a default and also it has some downsides as well. e.g. As a beginner, everything feels like magic in Rails, and you don't understand what is going on and how Rails understand while you didn't "explicitly" say what do you want sometimes.

Conclusion: Rails and Django are more productive and you can build projects on your own quickly (many giant startups launched this way!).

P.S: for learning RoR I suggest the book/video from Michael Hartl.

I picked Django because we use it at work. But honestly, if you don't know any of them, I would look at the jobs around where you live and learn the one that either has the most jobs posted or if you can look at the trends the one that is growing the number of jobs the most.

All three would satisfy your needs and all three are good choices. Dotnet core would also be a good choice, again if there are jobs in your area for said technologies. If you literally don't care about this for employment, learn them all and just do it in alphabetical order :)

Note: I think you are wrong about Node being too immature - there are also MOSTLY standards for everything you want to do on the backend that have not changed for many years.

Rails uses too much magic and sugar. Laravel is something from the previous century. I'd say Django can be well balanced choice. I have extensive experience with all three. So, this advice based on practical projects

I recommend Ruby/Rails. I write the text in question answer form:

Quick prototyping

Yes you can use the prototyping in Rails or not. And this can be realized by adding any of testing framework like Cucumber or RSpec for example. Writing the test you can work on the application prototype without a change real code in production, or even development environment.

Easy to get to production level for backend

Yes it is easy, you are able to use the capistrano gem with its modules, if required, to deploy application to production within a day.

Maintainable and buildable by one person alone

Since the Rails gets on itself the main code part of a data processing, you are able easily to generate the required code with build-in Rails or external gem generators, and to merely maintain the your code, if you would cover it with a test of selected test framework.

Enforces conformity, so others can easily read and contribute to the code, making successfully open sourcing possible

As far as I said you can barely control a contribution to your project with using the test covering frameworks, to keep conformity the project.

Works well with React

You can use React along with any JS NPM module easily using webpacker gem.

Has a mature and fairly stable ecosystem for the basics (auth, storage, db, image handling, backups, change history, etc.

Of course the Rails framework is supported by many three-side gems, which can be found at rubygems, that support the authentication (devise), storage feature (fog), db (pg/mysql/sqlite3), image handling (rmagick), backups (backup), change history (history)

Has an ecosystem that will still be alive in 10 years, responding to changes.

Ruby/Rails with the RubyGem ecosystem is actively envolving and not plan to be collapsed and abandned with of development both Ruby language and Rails framework.

So, you can freely and fearlessly start using the Rails framework as server side base for your project.

DJango after a little practice, with migrations and support to a lot of libraries and modules is very efficient to create small projects.

Edit: Between Laravel, Django or RoR (Ruby on Rails)
