The Performance Cost of Server Side Rendered React on Node.js

The Performance Cost of Server Side Rendered #reactjs on Node.js by @velmu

  • Note: After initial results I received feedback that I should define the environment variable NODE_ENV=production as this greatly improves performance of server side rendered React.
  • For throughput you can see that React is at a different league compared to the other templating engines when running without production settings, being close to ten times slower than the fastest traditional templating engine.
  • In production environment React performs again similarly to Nunjucks, but noticeably the average response time is significantly longer with the diffrence being some 70ms at concurrency of 250.
  • Like in throughput results, Pug performs close to ES6 template literals, but there is a consistent advantage in response times by the JavaScript native templating – some 12 percent at peak concurrency.
  • Throughput stabilises for both options from concurrency of 5 or more, but for high concurrencies the response time for uncompiled templates grows respectively more.

I like React as a templating engine, not only on the client side but on the server as well. Over the last year or two rendering templates with React.js on the server has become commonplace. Services from rather static content driven sites to Universal JavaScript Applications built on frameworks like Next.js are serving dynamic of server side rendered views using React.

How extensively/deeply do you validate props in React?

Do you validate props in your #ReactJS components? 🕵 How deeply?  #JavaScript #WebDev

  • Also setting isRequired on a component’s props is a valuable way of declaring mandatory props.
  • I then later realised the value in doing so because if you are a fresh pair of eyes on somebody else’s code, and looking at the props on a component that you are changing, at a glance you will see the required data types and structure for that component, even if that component is 3/4 layers deep.
  • To reduce the repetitive validation checks, when same props are being passed down around to multiple components, I create modules for prop interfaces and import that in individual components.
  • /IFormTheme’ class SomeFormControl extends Components { static propTypes = { theme: IFormTheme } …
  • At my company we do it the whole way down, I initially started doing this when my company’s EsLint config required it (you will get errors when linting etc.).

Do you even validate the internal structure of your props, or do you just validate at the top level?. Tagged with React Native,ReactJS.
