I think your choice of technologies are fine, but it you are starting new development I think your choice of architecture is most important. You can implement the desired architecture with many different technologies. Separating the layers of the application is important to allow each technology to be replaced or evolve independently. For example, I would write the code in a way that I could replace PostgreSQL with a different DBMS fairly easily in case a better alternative came along. The same goes for the React front end. If you have a good REST API you could replace the React front any with any framework, you could easily allow different locations to use Angular, Vue, or other front end technologies as long as the REST API is not designed to specifically target the React front end. I think the architecture of the code behind the REST layer, that would run in Express (the tool/language you are considering) is the decision that you will be stuck with for the longest time and that all other aspects of the application need to work around; so you want to get that architecture right. I think you should consider CQRS and Event Sourcing. https://docs.microsoft.com/en-us/azure/architecture/patterns/event-sourcing https://dzone.com/articles/cqrs-and-event-sourcing-intro-for-developers

IMO this is the wrong way to go about solving such a problem. If your current system is complex you need to find a way to migrate from it to something that works better. Rather than choose tools, figure out how to make the transition without breaking everything in the process. Starting over from scratch is almost always a bad idea. The design comes first. The tools come later. Perhaps take simple a piece of the system to modify without really changing any functionality. It's hard to provide better advice without understanding the details of your system.

I would really avoid building all of the scaffolding you need for the global server-server replication, eventual consistency and offline tools.

As long as your application architecture can fits a Key/Value pair type store, and you want master-master replication, then I'd start with AWS DynamoDB configured in Global Tables mode: https://aws.amazon.com/dynamodb/global-tables/

Then for offline-first access from client devices, use AWS Amplify, where (when used right) it's datastore feature will do most of the online/offline sync for you and let the developers focus on the mobile or web app. https://aws.amazon.com/amplify/features/#DataStore

I've had great success in using Amplify over very spotty connections (moving vehicles), using React and React Native for Web and Mobile applications respectively.

If your back-end data architecture really must be more RDBMS/SQL like, then consider whether you can use a central database in one geography, with all updates finding their way back there, then with read-replicas in other geographies. A good article on this, and suitable cloud-first databases to use, is here: https://read.acloud.guru/why-and-how-do-we-build-a-multi-region-active-active-architecture-6d81acb7d208

React might be a good option if you're considering a mobile app for the future, because of react native. Although, Vue.js has the easiest learning curve and offers a better developer ramp-up time. Vue.js is great to build SPAs, very clean and organized and you won't have a lot of long-term maintenance problems (like AngularJS, for example). Bootstrap can still be used, but with flexbox there's no need anymore.

I recommend React because of less memory occupant compare to Angular, but this will depend on your organisation flexibility. When you use React you need to import different libraries as per your need. On the other side angular is a complete framework.

Performance-wise I vote for react js as it loads up quickly and lighter on the mobile. You can make good PWA with SSR as well.

If you are new to all three react will be a good choice considering, react-native will be useful if you want to build cross platform mobile application today or tomorrow. If you are talking about bootstrap styling framework than it's a choice you can style ur components by ur self or use bootstrap 4.0 framework. The complete stack mentioned above is platform agnostic u can run it anywhere you want be it cloud or on-premise.

In my view, the upside of React is you're likely to find more existing, robust design systems (e.g. sets of components containing anything from buttons to datepickers) in the React ecosystem than Vue. UI frameworks aside, momentjs comes in when you want operate on the date(times) you get back from whatever datepicker you choose (e.g. date formatting, date match).

I've used both Vue.js and React and I would stick with React. I know that Vue.js seems easier to write and its much faster to pick up however as you mentioned above React has way more ready made components you can just plugin, and the community for React is very big.

It might be a bit more of a steep learning curve for your friend to learn React over Vue.js but I think in the long run its the better option.

I chose to use Vue.js a few years ago mainly for the easy learning curve. I have no experience with React, so I won't make any comparison here. Regarding available components, I never felt locked in because of Vue when looking for components. It happens that a component I wish to use is not available as a Vue component (and nobody published any Vue wrapper for it), but in such cases I was able to quickly hack a Vue wrapper component. In the end I don't think a decision to choose one framework over another should be made solely because of the number of components available. (And not all components in either framework is maintained, bug free, documented or easy to use)

I would also go with React. The learning curve can be a little more difficult but as soon as you got the concepts it's really easy to create things. As everybody has mentioned the React community is huge and it keeps growing, anything you may need for your project there are super high probabilities that you will find it.

React is great, Vue.js is also great. But I'm personally using React, because React is changing the way I look at how JavaScript should be. This is a really big plus for me. Vue is good, but it's just another alternative. Also, too many big companies are using React, that means you can trust it for big projects.

I'd have to concur that I'd advise React. In addition to the reasons mentioned, the developer pool is significantly larger (and also slightly more expensive) for React. In time, engineering costs will even out as more and more teams adopt it. The community support is fantastic, and the available components significant.

Would start with Vue especially if you want to progress more quickly and don't want/need to spend time learning React just for the sake of it. You can always pick up React later if necessary. I would caution about using "more readily available React components" just because they exist.

Both have their pro's and con's; however to agree what has been mentioned here before; Using Vue.js will be easier as it's learning curve isn't steep; plus learning Vue.js will teach you fundamentals which (in a sense) can be applied to React as well. Community support for React is indeed very big, but Vue.js is also still growing. Component wise, I wouldn't worry to much about that, writing your own components is also a good tool for learning a language.

Anything that interacts with the Internet, websites, applications, etc., while it may be more complex to build, will be easier to maintain in the long run. React offers more flexibility, a much larger support base for knowledge and opinion, and is just as stable asVue.

To make the best comparison in my opinion, think of React as the Android OS and Vue more like iOS. While Vue may be advantageous in some cases, it is limited by constricting parameters. On the other hand, while React may be more complex and incorporate more open-source/third-party constructs, it is supported by over 50,000 npm packages and allows for the use of JSX. Which I might add, once learned, becomes second nature to employ and offers more flexibility.

Having developed in both Vue.js and React, I agree with your assessment of Vue. It does feel light and easier to understand and therefore learn. Seeing that Vue has some genetic roots with React, I would say start your friend out on Vue. If they need to learn React later, that should give them a good foundation. If you have a Pluralsight subscription, look for my course on Vue.js and feel free to use the demo project as a starting point.

VueJS hands down. Which components do you need? Have a look at Vuetify, mature project, plenty of components ready to plug and play. If on the other side you need more customization, have a look at tailwindcss. VueJS is much cleaner and IMO will overtake React soon. It's simply a better React.

I would recommend both of them since Vue is a UI library and helps you to design beautiful website while react allows you to handle backend problems like comment management and onspot reloading more efficiently also react includes useState and react is a framework while vue is a library

Virtual dom and JSX. Vue is just a baby to the race. React has it's mobile platform version as react native . so it would be easy for you and you wont reinvent the wheel again for mobile apps.

We did a comparison between React, Vue and Angular and while found each capable of supporting our needs, we ended up using VueJS because of its ease of use, the ability to use templates, large and growing community and good documentation. After developing on it for a around 4 months we re-evaluated and agreed that we had made the right choice and continue to migrate our products/platform to it.

As others have stated there are more canned components available for React, but your observation about it's complexity is an important one. There are architectural aspects of Vue.js that lead to cleaner more concise solutions. As React apps get bigger they become a little unwieldy. Depending on your requirements you need to weigh those competing concerns. Our team is using React, but I am beginning to question that choice as time goes on. Another consideration is that Vue.js is becoming more mature as we speak. Also as others join the project, react developers should be productive in Vue.js within days. Just my 2 cents...

It is hard to say which is good. I've used both. Vue is easier. But I feel more comfortable with React. That is why I chose React.

It all depends. Vue.js is smaller, and from what I saw (benchmarks) faster. It's also slightly more intuitive and easier to grasp. React is more popular, and the adoption rate is much higher.

Again, it all depends.

If I may, my personal choice would perhaps be either React or Svelte.
