Boost Your Performance With RebelMouse’s New AMP-Rendering Engine

Using React + Node, AMP-powered sites provide a next-level user experience

RebelMouse is proud to announce a new rendering engine driven by Google's lightning-fast AMP format. In our relentless pursuit of world-class site performance, our team of developers put together a faster experience for our clients that includes a more cohesive codebase, quicker development output, and increased reliability and overall performance.

To do this, we used React and Node — JavaScript languages that appeal to a broad pool of developers. The same code can run on both servers and browsers, and allows us to leverage modern front end optimization tools.

Here's a quick rundown of what React, AMP, and Node are, and how RebelMouse has used them to create an AMP-focused front end experience that's fit for the next decade of publishing.


React is a JavaScript library for building user interfaces. It's maintained by Facebook and a community of individual developers and companies. React can be used as a codebase in the development of single-page and/or mobile applications. It's optimal for fetching rapidly changing data that needs to be recorded.

Accelerated Mobile Pages (AMP) is a web component framework and a website publishing technology developed by Google, created to pioneer "a user-first format for web content."

Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a browser.

We've worked with these technologies for years, but now we're excited to release a purpose-built renderer to get the most out of AMP experiences. Here's what this latest upgrade brings:

  • Performance Boost: Since it's faster, your AMP scores improve, which gives you an additional boost in Google's algorithm, as well as on Twitter.
  • Streamlined Workflow: We destructured our app into smaller React components. This upgrade makes it easier to test all parts of the app for further optimization.
  • One Codebase: Both the back and front end have the same code, which reduces code duplication and clutter.
  • Battle-Tested Tools: Webpack's top-notch bundling optimizations are specialized development tools that enhance the front end, which includes hot reloading of code at runtime.
  • Completely Reinvented CSS/Style Injection: There are no longer inline styles. We've also perfected the output optimizations and reduced duplication.
  • New Middleware Service (XML-to-JSX): We now process and cache data from our Layout & Design tool into digestible code on the fly. This includes boosting the computational performance of A/B tests.
  • Re-Engineered Post Content Data: By creating a Post Object Model (POM), we've increased the reliability of post composition functions, which greatly improves performance.
  • Ads Injection 2.0: The order of your ads is now much faster, with outstanding insertion precision.

Google Made Major Changes to Its Formula for Page Speed. Here’s What to Do About It in 2022.

Make sure your site is set up for success in 2022.

In the spring of 2020, Google let the world know that its Core Web Vitals would become the new benchmark for measuring a site's performance in its search results, known as the page experience update. Fast forward to more than a year later in August 2021 when, after much anticipation, Google's page experience update became official.

Since its rollout, developers have felt the impact of how their publishing platforms stack up against the new standard. Important decisions around the architecture of your site can now make or break your site's performance in the eyes of Google.

HTTP Archive, a tracking platform that crawls the web to identify trends and record historical patterns, has revealed how top content management systems (CMS) have weathered the page experience update through the creation of its Core Web Vitals Technology Report. RebelMouse consistently outperforms major CMS platforms on Google's most critical metrics since its rollout and into 2022:

Getting superior scores on Google's performance benchmarks isn't easy, either. The Ahrefs blog analyzed Core Web Vitals data from the Chrome User Experience Report (CrUX), which is data from actual Chrome users, to see how the web stacks up against Core Web Vitals. Their study found that only 33% of sites on the web are passing Core Web Vitals.

data from Ahrefs tracked on a line chart finds that shows only 33% of sites on the web pass Google's Core Web Vitals From Ahrefs.

Luckily, performing well on Core Web Vitals is possible with thoughtful, strategic changes to your site’s codebase. Here's what you need to know and how we can help.
