Performance Game Changer: Browser Back/Forward Cache. Performance Game Changer: Browser Back/Forward Cache. With that caveat out of the way, let’s get to the guts of the article: What is the Back/Forward Cache and why does it matter so much? Didn’t The HTTP Cache Do All That Anyway? Barry Pollard.
In this article, well discuss six ways to design websites for high-traffic events like product drops and sales: Compress and optimize images , Choose a scalable web host , Use a CDN , Leverage caching , Stress test websites , Refine the backend. You can also find optimization plugins or caching solutions that give you access to a CDN.
You are now “Head of Performance” at Repairing Magazine, the most serious competitor to Smashing Magazine. Repairing Magazine has a very peculiar business model. Repairing Magazine user interface relies on a modern JavaScript library, React. Let’s focus on a scenario very useful for blog owners: handling paid content.
Let’s illustrate this with some snippets: let smashing = {name: "magazine"}; // The object can be accessed from the reference. // Overwrite the reference smashing. let smashing = {name: "magazine"}; let arr = [smashing]; // Overwrite the reference. smashing = null; console.log(array[0]) // {name: 'magazine'}.
You can find a comprehensive Beginner’s Guide To Progressive Web Apps on Smashing Magazine that focuses on building the core of PWAs. The service workers enable the offline usage of the PWA by fetching cached data or informing the user about the absence of an Internet connection. Cached content with IndexedDB. Service Workers.
Smashing Magazine, like most publishers, makes use of web fonts and the below screenshot shows the difference between the initial render (with the fallback fonts), and the final render (with the web fonts): Smashing Magazine article with fallback font and with full web fonts. Large preview ). Large preview ).
However, if your content isnt dynamic, you can also cache responses at the CDN edge node. In many cases, we get a TTFB of under 200 milliseconds, thanks to the response already being cached at the edge node. For example, if they are logged into your application, the page content probably cant be served from the cache.
We’ve explored the concepts behind headless CMSes in detail here on Smashing Magazine, but let’s do a quick recap. From a developer perspective, not only static assets need to be cached on a CDN. Many headless CMSes cache content retrieved via RESTful or GraphQL APIs. Look out for: Caching of images and content via CDN.
As I was determined to become great at my new occupation regardless of my location, I read every sysadmin book, article, and magazine I could find on the shelf.
Active Memory Caching. When you want to get data that you already had quickly, you need to do caching — caching stores data that a user recently retrieved. Caching partially stores your data and is not used as permanent storage. Caching partially stores your data and is not used as permanent storage.
I vividly remember receiving a PC Magazine for my birthday with a trial of Dreamweaver. Smashing Magazine powered by Netlify. When we talk about static site generators, incremental regeneration, or instant cache invalidation, it’s enough to make the layman’s eyes glaze over. Large preview ). Government.
Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. The cache is invalidated on a time basis. Creating an On-Demand builder.
We’ll be learning how to do this with GraphQL Features like Cache Update, Subscriptions, and Optimistic UI. Updating the cache directly using update function on the useMutation. Updating the cache directly using update function on the useMutation. This lets us update our client-side cache immediately with consistent data.
On top of this foundation, we add layers of caching, prerendering and edge delivery optimizations — not the other way around. Hydrogen fuels dynamic commerce by uniting React Server Components, streaming server-side rendering, and smart caching controls. Large preview ). This is not a debate about dynamic vs. static.
Webpage performance test report for the Smashing Magazine website. Cache Your Images. A website’s performance can suffer if frequently accessed images are not cached, as many requests will be made to images that have already been loaded in the user’s system. Large preview ). The Relation Between Images And Web Performance.
It is based on a caching strategy called “stale while revalidate”, meaning a page can be “stale” with old information until it’s re-generated and the cache is updated. When the non-built pages are requested for the first time, they are built and cached at the edge so they don’t need to be built again.
As a result, users can enjoy more capable and feature-rich applications that remain performant through techniques like code-splitting, caching, prefetching, and other resource optimization techniques — with some applications that are even able to work offline. Further Reading on Smashing Magazine. “ How To Maintain A Large Next.js
Search Engine And Web Archive Cached Results. Another common category of imposter domains are domains used by search engines for delivering cached results or archived versions of page views. The message that appears above a cached search result in Google’s search service. Further Reading on Smashing Magazine.
Examples of this might be, expecting that the HTML is fully static, such that we can cache it downstream in some deterministic manner — “partially dynamic” HTML bodies are much more likely to be handled incorrectly by caching logic. Here are a few that come to mind: Is this request served from the service worker cache?
Browser Caching. Another built-in optimization of Google Fonts is browser caching. As the Google Fonts API becomes more widely used, it is likely visitors to your site or page will already have any Google fonts used in your design in their browser cache. — FAQ, Google Fonts. Further Optimization Is Possible.
These numbers are based on first-page load — caching seems very efficient for subsequent page loads. navigator.share({ title: 'Smashing Magazine', text: 'Web development news and tutorials', url: '[link] }). Two embeds. Description. JS (uncached). Single embed. Two embeds.
MB , that suggests I’ve got around 29 pages in my budget, although probably a few more than that if I’m able to stay on the same sites and leverage browser caching. There’s a trade-off to be made here, as external stylesheets can be cached but inline ones cannot (unless you get clever with JavaScript ). Let’s talk about caching.
Your application might also suffer from caching, and performance issues. They handle a lot of things like caching and performance which are difficult to manage on your own. These packages will fetch and cache async data from your back-end API endpoints and make your application state much more maintainable.
Another benefit of moving computations from browsers to servers is that the results of these computations can often be cached and reused between sessions even for unrelated visitors, thus reducing per-session execution time dramatically. The results of some of these APIs are also cached in a CDN as appropriate. Large preview ).
Let the web developer handle all of the necessary speed optimizations like caching and file minification while you take on the following design tips and strategies: 1. Because service workers exist outside of the web browser and are not contingent on the speed of the user’s network, they load cached content for visitors more quickly.
Are all the caching headers set correctly? It also points out a too complex HTML structure, and it also checks your server and cache header configuration. Three Front-End Auditing Tools I Discovered Recently. Stefan Judis. 2021-06-10T11:15:00+00:00. 2021-06-10T12:51:06+00:00. Is every resource properly minified and compressed?
If you haven’t heard, INP is replacing the First Input Delay (FID) metric, something you can read all about here on Smashing Magazine as a guide to prepare for the change. But that’s not what I really want to talk about. With performance at the forefront of my mind, I decided to head over to MDN for a fresh look at the Performance API.
Inspired Design Decisions: Avaunt Magazine. NB: Smashing members have access to a beautifully designed PDF of Andy’s Inspired Design Decisions magazine and full code examples from this article. Inspired Design Decisions: Avaunt Magazine. Read More From The Series. Inspired Design Decisions: Pressing Matters.
As I was determined to become great at my new occupation regardless of my location, I read every sysadmin book, article, and magazine I could find on the shelf.
Nx is an open-source build framework that helps you architect, test, and build at any scale — integrating seamlessly with modern technologies and libraries, while providing a robust command-line interface (CLI), caching, and dependency management. Nx uses distributed graph-based task execution and computation caching to speed up tasks.
Barry Pollard, a web performance developer advocate for Chrome, wrote an excellent primer on the CrUX Report for Smashing Magazine. CrUX is what fuels PSI and Google Search Console, but it is also available in other tools you may already use.
So, to improve the TTFB, we need to speed up that process or cache the HTML so we can skip the HTML generation entirely. In this example, we can see that creating the server connection doesnt take all that long. Most of the time is spent waiting for the server to generate the page HTML.
It also opens up the possibility for more effective use of caching strategies, potentially enhancing load times further. Their primary role is to store (or “cache”) copies of web content — like HTML pages, JavaScript files, and multimedia content — and deliver it to users based on their geographic location.
The solution used in Scrapbook was to use the SWR library of React hooks to update the cached page from the server with client side data fetching. The client is first served the cached statically generated page (generated with getStaticProps() ), in the background the server also begins the process of revalidating that page (read more here ).
Jump to the workshops ↬ Using CDN For Caching And WebP For Lighter File Sizes As I mentioned a little earlier, our stack includes Sanity’s CMS. It offers a robust content delivery network (CDN) out of the box , which serves two purposes: (1) optimizing image assets and (2) caching them. Let’s see the query caching in action.
In this screenshot below, for example, we can see that loading the Smashing Magazine website for the first time incurs just under a megabyte of data transfer. I predominantly use Nginx, and I have a particular fondness for FastCGI cache and have found it to be especially efficient. Large preview ). We should use HTTP2 over HTTPS.
Today, we’ll address storing and serving files for both single-server and scalable deployments while considering factors like compression, caching, and availability. Client-Side Caching. Caching is the process of storing the results of a computation or request so that they can be accessed repeatedly more quickly. In Conclusion.
This approach was touted to be better for fine-grained caching because each subresource could be cached individually and the full bundle didn’t need to be redownloaded if one of them changed. Upon receipt of a valid Alt-Svc header indicating HTTP/3 support, the browser will cache this and try to set up a QUIC connection from then on.
Libraries like these handle cache locally, so whenever the state is already available they can leverage settings definition to either renew data or use from the local cache. zero-config caching layer. As you can see above, the useSWR hook provides a lot of abstractions: a default fetcher. error handler. loading handler.
Due to the use of modern frameworks, advanced caching and rendering, and data transmission via API, properly developed PWAs can be a seven-league step up to boost the store’s speed. To specify, users can continue using those parts of the site that were cached if the Internet connection is unstable or when offline. Large preview ).
The browser caches the results of these lookups, but they can be slow. You might think of a prefetch as being a bit like adding a file to the browser’s cache. For a busy page with lots of external resources (like perhaps a news website with loads of ads and trackers), there might be dozens of DNS lookups required per page.
We can use 11ty’s new Serverless mode to build them on request using Netlify’s On-Demand Builders to cache each Madlib. For example, an “On-Demand Builder” is a serverless function dedicated to serving a cached file. Netlify then caches that page on its edge CDN for each additional call. Large preview ). More after jump!
This video game-like environment goes through the service worker lifecycle, intercepting requests, working with caches, and more. Service Workies is an interactive adventure game to learn various features for developing Progressive Web Apps (PWAs). Image source: Service Workies ). Tools To Learn Miscellaneous Web Dev Skills.
You can adjust what browser is used, the kind of network connection to employ, the locations to test from, whether or not the browser’s cache is empty or full, how frequently to take the measurements, and more. If you cannot avoid having third-party fonts on your site, consider using font-display properties in your CSS.
