use React or Vue over server side template engines

Asked By: Anonymous

For web development React or Vue seem to be a must have framework. Currently I just got some experience with NodeJs and Handlebars.

I know Handlebars runs a server side rendering, Vue and React run a client side rendering. Using Vue or React makes reusable components possible. Using a server side template engine requires a base layouting.

Let’s say I have a website / webapplication with some routes. Why should I use Vue for HTML components instead of Handlebars HTML?

What I learned so far is that whenever I can

  • improve my SQL statement, do it before manipulating the data by code
  • do something at the client that can be done by the server, do it at the server because it has more power

Everyone is using Vue or React now, why should I leave the old structure and start outsourcing the code to the client?

I believe your question is more tied to the concept of server-side rendering and client-side rendering.

Server-side rendering has a few important points that you should consider when evaluating a problem:

  • Is faster to render the page in the server than in the client
  • It is much better for SEO(Search Engine Optimisation), since the crawlers can craw the entire page. Since some crawlers are not
    evaluating/running javascript, a SPA(Single Page App) will probably
    result in an empty page. Even though Google has improved quite a lot
    with SPA SEO, server-side rendering is still the best option.

Client-side rendering, using SPAs, has different advantages:

  • Is much better to manipulate and maintain user state in the client-side, since you can have your webpage broken down into
  • Faster interactions/page changes after the first load, since, in most cases, the entire app is loaded at once in the first request.

So with that in mind, you have to consider what you want to do. If you are building some website that reflects a more page-like structure, like a news or blog, server-side rendering is probably the best way to go.
On the other hand, if you are building a full-blown application that has loads of user interactions and state management, client-side rendering (or SPA) could be the best option.

There is no reason to outsource your code to the client-side without evaluating your problem first. That really depends on the problem you are trying to solve.
