Implementing a micro frontend architecture can bring many benefits to a project, such as increased flexibility, scalability, and maintainability. However, it can also introduce challenges, such as ensuring consistency across microfrontends. One of the best practices to address this challenge is to use a common performance optimization framework. This framework should provide a set of guidelines, tools, and best practices that all microfrontends should follow to optimize their performance. By doing so, the performance of the entire application can be improved, and inconsistencies can be minimized.

One example of such a framework is the Google PageSpeed Insights. This framework provides a set of guidelines and tools to optimize the performance of web pages. It covers various aspects of performance, such as page load time, rendering time, and resource optimization. By following the guidelines provided by this framework, microfrontends can ensure that they are optimized for performance and that they are consistent with each other. For example, they can all use the same image optimization techniques, caching strategies, and compression algorithms.

Another example of a performance optimization framework is the Lighthouse. This framework provides a set of tools to audit the performance, accessibility, and best practices of web pages. It covers various aspects of performance, such as page load time, rendering time, and resource optimization. By using this framework, microfrontends can ensure that they are optimized for performance and that they are consistent with each other. For example, they can all use the same HTML structure, CSS styles, and JavaScript libraries.

// Example of using Lighthouse in the pipeline using npm
npm install -g lighthouse
lighthouse https://www.example.com --output json --output-path ./report.json

// Example of using Google PageSpeed Insights API to optimize images
const image = document.querySelector('img');
const imageUrl = image.src;
const optimizedImageUrl = `https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=${imageUrl}&strategy=mobile&category=images&optimizedImages`;
fetch(optimizedImageUrl)
  .then(response => response.json())
  .then(data => {
    const optimizedImage = new Image();
    optimizedImage.src = data.lighthouseResult.audits['optimized-images'].details.items[0].url;
    image.src = optimizedImage.src;
  });
