The Speculation Rules API: A Guide to Faster Websites

Constantine — Mon, 06 May 2024 08:58:19 +0000

In the pursuit of seamless user experiences, the Speculation Rules API offers web developers a powerful tool to combat the latency that often accompanies web page navigation. By instructing the browser about likely user actions, this API enables proactive resource prefetching and even full-page prerendering, leading to significantly faster-perceived load times.

Understanding the Speculation Rules API

The core principle of the Speculation Rules API is providing predictive hints to the browser. Developers have the flexibility to indicate potential page navigations, empowering the browser to anticipate user behaviour and optimize resource loading ahead of time.

Prefetching vs. Prerendering

Prefetching: The browser downloads a target document and its associated resources (images, scripts, etc.) and stores them in its cache for later use. This ensures immediate availability if the user navigates to that page.
Prerendering: This takes preloading further by instructing the browser to render the entire document (including JavaScript execution) in a hidden state. The user clicks the link, the prerendered page is displayed almost instantaneously.

Speculation Rules in Practice: Code Examples

Speculation Rules are expressed in JSON format and can be embedded either inline in the HTML or served as a separate file:

E-commerce Product Listings:

{
    "rules": [
        {   
            "source": "list",
            "urls": [ 
                "/product/12345", 
                "/product/56789" 
            ]
        }
    ]
}

Blog Pagination:

{
    "rules": [
        {   
            "source": "list",
            "urls": [ "/blog/page/2" ] 
        }
    ]
}

Search Results with “Next page” Link:

{
  "rules": [
    {
      "prerender": [{
        "urls": ["/list*"],
        "expects_no_vary_search": "params=(\"page\")"
      }]
    }
  ]
}

Example: <a href="/list?page=2">Next page</a>

Injecting rules dynamically:

function preloadPages(urls: string[], specType: 'prefetch' | 'prerender' = 'prefetch') {
  if (!HTMLScriptElement.supports?.HTMLScriptElement.supports("speculationrules") {
    return;
  }

  const specScript = document.createElement("script");
  const specRules = {
    [specType]: [{ "source": "list", urls }],
  };

  specScript.type = "speculationrules";
  specScript.textContent = JSON.stringify(specRules);

  document.body.append(specScript);
}

Browser support

The Speculation Rules API is currently supported in Chromium-based browsers (like Chrome, Edge, and Opera), which cover approximately 70% of the global browser market. While it doesn’t yet function in Firefox or Safari, it won’t break anything if you start using it today. Users on other platforms will gradually experience its benefits as browser support expands.

If you need 100% coverage, you can use the old APIs and . More information from Addy Osmani: https://medium.com/reloading/preload-prefetch-and-priorities-in-chrome-776165961bbf.

How we use it in our extension

We use the Speculation Rules API in the MaxFocus: Link Preview extension to improve preview loading speeds. When a user’s behaviour indicates they prefer the “Open on a long click” method, we dynamically inject Speculation Rules with the “prefetch” directive on the ‘mouse down’ event. This tells the browser to start preloading the linked page’s resources in the background, ensuring a near-instant preview experience when the user finally long-clicks to open it.

Optimizing data flow with the keep-unchanged-values library

Constantine — Fri, 01 Dec 2023 08:19:11 +0000

Hello everyone! If you're dealing with frequent data updates in your frontend development projects, especially from sources like backend servers or localStorage, this article is essential for you. Discover how the keep-unchanged-values library can enhance your React applications by optimizing data updates and minimizing performance issues. You need this if you're navigating through regular updates from various data sources.

Problem: Frequent data updates in large objects and lists cause performance issues

Solution: keep-unchanged-values combined with React.memo

How it works:

Pass two entities to the keepUnchangedValues function you want to "merge". The result is the second entity, and it will keep references to unchanged objects from the first entity:

const oldArray = [1, { a: 1 }, 3];
const newArray = [2, 3, 4, { a: 1 }];

 // result is equal to [2, 3, 4, { a: 1 }]
const result = keepUnchangedValues(oldArray, newArray);

// logs true; result[3] will be a reference to oldArray[1] since they have the same link to the object
console.log(result[3] === oldArray[1])

Example:

Update data from external storage periodically
"Merge" new data with existing using keepUnchangedValues
Update your state with "merged" data: the old nested objects will be the same, new data will be applied

import React, { useState, useEffect } from 'react';
import { keepUnchangedValues } from 'keep-unchanged-values';

const MyListComponent = () => {
  const [list, setList] = useState([]);

  useEffect(() => {
    // Fetch data from API
    const fetchHandler = () => {
      fetchData().then(newItems => {
        // Update the list with new items, maintaining unchanged ones
        const updatedList = keepUnchangedValues(list, newItems);
        // if nothing changed, returns the same list
        setList(updatedList);
      });
    }
    // Fetch initial data
    fetchHandler()
    // Set up polling
    const intervalId = setInterval(fetchHandler, 5000); // Polling every 5 seconds

    return () => clearInterval(intervalId);
  }, [list]);

  return (
    <ul>
      {list.map(item => <MemoizedListItem key={item.id} item={item} />)}
    </ul>
  );
};

const MemoizedListItem = React.memo(({ item }) => {
  // Rerenders only if the current item changes.
  // Works with shallow comparison because keepUnchangedValues maintains unchanged values
  useEffect(() => {
    somethingIneficient(item);
  }, [item]);

  return <li>{item.content}</li>;
});

export default MyListComponent;

Benefits:

Unchanged list items retain their references
React.memo performs shallow comparisons and skips re-renders for unchanged items

Result? Smooth, efficient data updates!

Optimizing performance: how our extension became lightning fast

Constantine — Fri, 20 Oct 2023 14:41:55 +0000

This article is for website creators who have some knowledge of backend and NGINX. It's about how we improved our browser extension to make it faster and better. By reading it, you'll learn about the tools and tricks we use to fix slow loading and other annoying problems.

What is Casca?

Casca is a browser extension that replaces your default new tab into a personalized dashboard. It lets you set up different workspaces (like one for work and one for personal stuff), customize your dashboard with helpful widgets, interact with ChatGPT, choose nice backgrounds, preview websites and more. It’s all about making your online space tidy and efficient.

Why Speed is Important to Us

At Casca, we prioritize the speed and performance of our extension for several reasons:

Enhanced User Experience: Our main focus is to make sure our users have a fast and responsive browsing. Applications that are slow can make devices perform poorly and cause browsers to be slow as well. That's why our aim is to give our users a smooth and enjoyable online experience.
Optimized Resource Usage: We know that many users have devices that don't have a lot of power and that don't last long on a single charge. Apps that take a long time to load can use up these resources and make the device work slower. It is designed to use as little of these resources as possible, so users can browse the internet without their device slowing down or feeling laggy.
Productivity and Efficiency: A quick app saves time and helps you get things done faster. By reducing the time it takes to load and respond, it allows users to work more efficiently and complete tasks more quickly.
Reliability and Trust: A slow and unresponsive app can make users lose trust. Our goal is to provide a browsing solution that is dependable and fast. By prioritizing speed and responsiveness, we demonstrate our commitment to delivering a top-notch product that meets user expectations.

Our tech stack

To build Casca Extension, we used a bunch of different technologies such as:

React, Tailwind and React Grid Layout to make the extension fast, scalable and beautiful
IndexedDB to store large data right in the browser
Node.js, Express and MongoDB to proxy, map and cache external API requests
Sharp library to compress large images
NGINX serves as a load balancer for all requests and utilizes NGINX Content Caching to cache slow responses from the Sharp library

How We Fixed Things

Fixing Images & Favicons

By using NGINX Content Caching and IndexedDB, we have improved the way we get large background images and multiple favicons. This means we can quickly save and retrieve images from a cache so they can be accessed immediately in the future.

A part of our NGINX configuration:

proxy_cache_path  /var/www/cache/nginx levels=1:2 keys_zone=background-images:8m max_size=3000m inactive=1200m;
proxy_temp_path /var/www/cache/nginx/tmp;

location /api/casca/favicon {
  proxy_pass <SERVICE_ADDRESS>/api/casca/favicon;
  proxy_cache my-cache;
  proxy_cache_valid  200 302  24h;
  proxy_cache_valid  404      5m;
}

location /api/optimize {
  proxy_pass <SERVICE_ADDRESS>/api/optimize;
  proxy_cache background-images;
  proxy_cache_valid  200 302  7d;
  proxy_cache_valid  404      1h;
  add_header Access-Control-Allow-Origin *;
  #limit_req zone=one;
}

Express.js middleware:

app.get("/api/optimize", async (req, res) => {
  const image = await fetchImage(req.query.url.toString());
  sharp(image.buffer)
    // webp is a modern image format that provides lossless and lossy compression for images on the web
    .toFormat('webp', { 
    // compress image to 90% of original quality. It doesn't mean that the image will be 10% smaller
      quality: 90,
    })
    // resize image to 1920px width. It's a pretty common resolution for desktops
    .resize({ width: 1920 })
    // make a blob and send it to the client side
    .toBuffer((_, buffer) => res.end(buffer, "binary")); 
})

And usage on the client side:

// Background.jsx
export default function Background({ imageURL, className }) {
  return (
    <img
      src={VITE_RESIZE_ORIGIN + "/api/optimize?url=" + encodeURIComponent(imageURL)}
      className={className}
      alt="Background image"
    />
  )
}

These optimizations made a big difference. For example, our background image used to be a large 1.9MB, but with the Sharp library, it's now just 334kB. This not only speeds up loading but also saves on network data and RAM usage. This makes the Casca Extension work smoothly, even on devices with less memory, providing a better user experience.

The original image and our highly optimized copy:

The differences in quality are not noticeable to the naked eye.

Dealing with slow requests

To fetch data from other websites, we used Node.js and Express to create a middleware. It allows to save and serve the data quickly, even if the original website is slow.

In addition, we store the fetched data in the localStorage cache. Therefore, the data is accessed offline and updated only when subsequent requests are fulfilled.

Stopping unneeded re-renders

useMemo, useEvent: We memoized immutable data and functions to avoid redundant re-renders, ensuring that only the components witnessing data alterations are re-rendered.

The implementation of the useEvent hook:

import { useCallback, useRef } from "react";

export function useEvent(cb) {
  const cbRef = useRef(cb)

  // Update the callback reference when the callback function changes
  cbRef.current = cb

  // Return a memoized callback function. No hook dependencies are needed
  return useCallback((...args) => cbRef.current(...args), [])
}

Usage:

export default function App() {
  const [value, setValue] = useState(0)

  // 1. It will always return the same function
  // 2. There will be the actual value in the closure
  const handleIncrement = useEvent(() => setValue(value + 1))

  return <SomeLargeComponent onSubmit={handleIncrement} />
}

There are multiple names for this hook. You can find the documentation under the names useEvent or useEffectEvent.

keep-unchanged-values: This library is specifically deployed for regular data fetching scenarios. It prevents unnecessary re-renders by keeping unchanged values and only updating altered data.

// useStorageData.js
export function useStorageData(selectorFn) {
  const [data, setData] = useState(() => selectorFn(getData(storageKey)))

  useEffect(() => {
    const unsubscribe = onStorageChange(({ newValue }) => {
      const selectedData = selectorFn(newValue)
      const nextData = keepUnchangedValues(data, selectedData) // <-- the usage is here
      if (nextData !== data) setData(nextData)
    });

    return unsubscribe
  }, [data])

  return data
}

// TodoItems.jsx
export default function TodoItems() {
  const storageData = useStorageData((data) => ({ items: data.todoItems || [] }))

  return (
    <>
      {storageData.items.map(item => <MemoizedTodo key={item.id} item={item} />)}
    </>
  )
}

// Don't need to use deepEquals to check the props equality
// keepUnchangedValues returns an unchanged item
// if it finds it in the previous array (prevProps.data === nextProps.data is true)
const MemoizedTodo = React.memo(function Todo({ data }) {
    return <div>{data.title}</div>
})

Tips for Extension Developers

To build a fast browser extension, it's important to consider more than just writing efficient code. Here are some tips for frontend developers:

Optimize images and assets: Large images can slow down your extension. Compress images and use formats like WebP. Implement lazy loading to load images only when needed.
Speed up server requests: Slow server requests can be a performance bottleneck. Use caching, CDNs, and browser caching. Minimize unnecessary API calls by storing data locally.
Avoid unnecessary re-renders: Prevent components from re-rendering when data hasn't changed. Use techniques like useEvent, useMemo and React.memo in React to optimize rendering.
Optimize data storage: Choose the right data storage method. IndexedDB is great for storing large data sets in the browser. Manage data efficiently and plan for offline access and synchronization.
Focus on user experience: Speed should improve the user experience. Test with users and gather feedback to identify areas for improvement. Prioritize a smooth and responsive interface.
Keep an eye on memory usage: High memory usage can slow down your extension and the browser. Keep an eye on memory consumption and optimize your code to reduce unnecessary memory use.

By following these tips, you can make sure that your browser extension runs well and efficiently, giving your users a better experience.

Wrapping Up

Leveraging technologies like React, Tailwind, and React Grid Layout, we have created a visually appealing and scalable extension.
We have optimized the handling of large images and favicons through NGINX Content Caching and IndexedDB.
Slow requests have been addressed by implementing Node.js and Express middleware.
Techniques like useMemo and useEvent hooks have minimized unnecessary re-renders.
The integration of the keep-unchanged-values library has further improved performance.

We have made the Casca Extension much faster and more efficient by using different technologies. We fixed problems like slow loading of images and favicons, dealing with slow requests, and reducing unnecessary re-renders. As a result, our users now enjoy a quick and smooth browsing experience. We prioritize speed and responsiveness to ensure a seamless and enjoyable online experience without using too much of your device's resources. We will continue to improve our technology to keep Casca lightweight and efficient for our users.
