React.js Efficient Server Rendering (Using Node.js as a Proxy Server)

Without a doubt, React.JS is one of the best solutions for developing web apps as it provides dynamic benefits. You can hire React developers from top agencies for the frontend rendering techniques and processes involving this library. They can handle complex and simplistic codework with React.JS, guaranteeing scalability with the JSX components. They have the ability to handle frontend development steps with the modules in the React.js libraries.

However, it is notable that some projects require better performance levels with load time management in frontend web pages. Additionally, sometimes, there is a need to focus on SEO-related factors with a focus on dynamic JSX content. At this point, it is possible to use React.js for server-side rendering, operating with a proxy server. Of course, you need to hire a suitable development team, like those at BOSC Tech, for this type of work.

In this article, we shall detail what this process covers, so read ahead.

Server-side Rendering with React.js

Certainly, Facebook allows developers the ability to render coding in web apps on the server side with React.js. For this, they can take the help of the basic components and functionality of Node.js. Using this, the workflow involves the following sequence.

  1. The client sends a request for the JSX template page to Node.js.
  2. The servers of Node.js acquire the sent file with the JSX code.
  3. The codework is rendered in the form of plain HTML programming.
  4. The software sends the HTML response back to the main client.
  5. React.js client-side coding works with HTML markup. Developers can include dynamic logic within the rendered HTML.

Therefore, the HTMT content will appear before React rendering completes.

The Lack of Node.js Backend

In some cases, like for a Python Django-centric project, many of the Python-based codework will remain. So, even if one uses React.js for frontend programming, the Python elements stay in the backend. However, sometimes, it is impossible to rewrite every piece of code to make it suitable for server-side rendering.

One can embed JS engines with Python framework in such big-scale projects and proficiently handle server-side rendering. But this process is not always necessary, especially if you have to embed JS engines for server-side rendering separately.

Here, preparing a standalone type of Node.js server for React.js JSX-centric template rendering is a suitable choice. For this, you can take the help of experienced React.js developers who can test and prepare the best proxy server for your personalized needs. This can efficiently help with the performance boost of the rendering process to a high extent.

The Python server for your Python Django project would prepare and send the proxy request directly to the Node.js server. Then, the latter would focus on JSX content rendering, using the JSX code in the requested file. It will prove the native HTML coding to its original Python Django template.

With this proxy rendering process, you can expect a faster server-side process for the HTML pages. Plus, you can provide Search Engine Bots and web crawlers with JSX content faster with this approach.

How to Implement Proxy Rendering?

Here, we provide a basic snippet of a code that can benefit from this type of proxy rendering as a reference:

import requests

import json


ProxyAddress = ‘’


def recieve_html(file, prop):


       props_str = json.dumps(prop)

       r = + file

                         , data=props_str

                         , headers={‘Content-Type’: ‘application/json’})

       if r.status_code == 200:

           return r.text, props_str

   except Exception as exp:


   return False, False

To note, this type of code helps provide the POST request directly to the proxy Node.js server, which sends back the rendered response with HTML code.

Main benefits to notice with the proxy server-based rendering approach

Here, you can note specific types of profit points:

  • It is possible to retain the JSX cache and decrease overall load time.
  • No Node.js integration is necessary.
  • Developers can avoid using JavaScript engines via Python.
  • It is highly flexible in completing codes with this method since the primary work here is to pass a specific object to the Node.js server and get the HTML code back.
  • It is possible to scale all backend services with no major changes to rendering services. So, you can use it on a cached rendering server with more than one server and expect better performance quality.

Production of Proxy Rendering Tools

The production process for Proxy Rendering tools has been undergoing processing for some months, with no restart and minimal CPU usage. The initial page rendering took 600MS on average. The average HTML responsive time recorded 10MS due to the need for caching with Node.js and its service caching.

Indeed, with efficient React developers, you can expect a simpler experience with this process and better results. Those at Bosc Tech Labs are reliable and trained in such work and would provide dedicated service throughout the partnership. So, reach out to the team whenever!
