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.
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.
The output of the code above would be the following: WeakMap {{…} => 'done'} man = null; console.log(human). The object is retained in memory and can be accessed with the following code: console.log(human[0]). let human = new WeakMap(): // Create an object, and assign it to a variable called man. It keeps the object in memory.
You can find a comprehensive Beginner’s Guide To Progressive Web Apps on Smashing Magazine that focuses on building the core of PWAs. You’ll also find example code or references to more specific guides so you can implement these tips to your PWA. Cached content with IndexedDB. Skeleton screen examples on Code My UI.
Half of the time is instead spent on a cross-origin redirect — a separate HTTP request that returns a redirect response before we can even make the request that returns the websites HTML code. However, if your content isnt dynamic, you can also cache responses at the CDN edge node.
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 ).
Creating A Magento PWA: Customizing Themes vs. Coding From Scratch. Creating A Magento PWA: Customizing Themes vs. Coding From Scratch. One of the reasons for that is because a PWA has the same code base. So unlike the case with native applications, the progressive web app needs to be coded only once. Alex Husar.
We’ve explored the concepts behind headless CMSes in detail here on Smashing Magazine, but let’s do a quick recap. All functionality and integrations would also have a tight dependency which in turn results in a large, cumbersome monolithic code base. Comprehensive documentation and code samples are also a must.
However, unlike the early days of the web, static sites are no longer limited to developers working in a code editor. I vividly remember receiving a PC Magazine for my birthday with a trial of Dreamweaver. The benefit of doing this is the entire site’s source code can live in Git. Smashing Magazine powered by Netlify.
Every unnecessary bit of JavaScript code you bundle and serve will be more code the client has to load and process. How will you serve blazingly fast code, then? Jamstack is popular with documentation sites that usually compile code to HTML files and host them on the CDN. Active Memory Caching. Caching Schemes.
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. It is not possible to ship code incrementally.
We’ll be learning how to do this with GraphQL Features like Cache Update, Subscriptions, and Optimistic UI. Let’s get right into the code. Just before we start, this is the repo containing the code demonstrating everything under Real-time update on GraphQL, using Apollo as a state management tool, Fragments, and Apollo directives.
However, there are a few ways in which you can make a large code-base easy to maintain. In certain cases, the build will fail if there are type mismatches in your code as Next.js We recommend using code editor type checking during development.”. Use Code Generators Like Hygen To Generate Boilerplate Code.
Webpage performance test report for the Smashing Magazine website. In that case, you can always use the <picture> HTML tag, as shown in the code below, so that the browser can pick the image format supported in the order provided. <picture> Cache Your Images. Large preview ). <picture> <!--
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. “
Approximately two-thirds of Indian mobile Chrome users of Smashing Magazine have this setting turned on, for example. For Smashing Magazine, that involved dropping some of our web fonts. And Is It Used? Again, I talked about this that previous article , and the answer is a resounding yes! Data Saver. Network Signals.
Examples of non-timing information you could send: HTTP Response status code, regions, request ids, etc. This is how they offer drop-in monitoring of all requests being made without us needing to change our code to monitor a request. Code used to monitor resources (fetch, XHR, images, stylesheets, scripts, HTML, etc.)
They all generally are instrumented as JavaScript processes that are loaded onto your site’s web pages through a tag or snippet of loader code. 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.
And once the teams started working off of the knowledge, it meant organizing performance-focused design and code reviews, training and education, plus providing tools and assets to support these ongoing efforts. In addition, this significantly reduced the amount of JavaScript code that needs to be downloaded by the browser.
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. A 75% saving!
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.
So, to improve the TTFB, we need to speed up that process or cache the HTML so we can skip the HTML generation entirely. That way, loading images no longer depends on first loading JavaScript code. That way, the browser can start loading it as soon as the HTML code is ready.
Clean coding practices. 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. Granted, some plugins are coded to be more lightweight than others, but there will always be some sort of difference felt in your loading times.
These numbers are based on first-page load — caching seems very efficient for subsequent page loads. With detailed code walkthroughs , hands-on examples and common gotchas — all broken down into short, manageable lessons. navigator.share({ title: 'Smashing Magazine', text: 'Web development news and tutorials', url: '[link] }).
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.
Over the last little while, I’ve been able to collect links to several interactive coding tools and apps that can help you supplement your skills in different areas of web development. This is a straightforward flexbox playground that also generates the code for you. “code golf”). Image source: Flexy Boxes ).
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 what code is actually running and causing those delays? But that’s not what I really want to talk about.
iOS empowers developers to easily parallelize code using Grand Central Dispatch , Android does this via their new, unified task scheduler WorkManager and game engines like Unity have job systems. How long your piece of JavaScript takes to finish depends on how fast the device is that your code is running on.
To mitigate the performance issues, we had to add a lot of (unbudgeted) extra servers and had to aggressively cache pages on a reverse proxy. The code you write visualizes instantly in your browser and productivity goes through the sky. The smallest changes in your code can lead to a drop in performance and other Core Web Vitals.
Its name, “ memo ” comes from memoization, which is basically a form of optimization used mainly to speed up code by storing the results of expensive function calls and returning the stored result whenever the same expensive function is called again. Webpack suggests three general approaches to code-splitting: Entry points.
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 ).
Using the proposed file structure is not a bad way of structuring your project per se, but as your project grows, you will need a better structure as your code becomes clustered and harder to navigate and access files. code some certain instructions that are peculiar to Vue.js. As we are newly creating a project with Vue.js
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. You can read about more advanced dead code elimination (aka tree shaking) in this post for Google by Jeremy Wagner. Data transfer is one thing that we can measure quite easily.
It’s not just source code for the configuration, models, views, and templates, but also static assets: CSS and JavaScript, images, icons. Today, we’ll address storing and serving files for both single-server and scalable deployments while considering factors like compression, caching, and availability. Philip Kiely. Static Files.
A route will wrap other routes and thus provide them with common definitions instead of making developers duplicate code. Now we have readable code and we can pass props down to our components touching only required layers. zero-config caching layer. With this in mind, there is a Wrapper Proposal in Next.js tai has surfaced.
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.
In many cases, they can be super convenient to add or remove without having to push code changes to the site. For example, users can install browser plugins to suggest coupon codes when they are shopping, to scan web pages for malware, to play games or message friends, or do any number of other things. More after jump!
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.
It’s well known that the amount of JavaScript used by a page can have a direct impact on its performance because all the code needs to be downloaded, parsed and executed. As a result, Svelte doesn’t need to deploy the code required for such functionality. I assume that caching, both in the browser and CDNs, contributes to this as well.
Let’s illustrate the browser’s behavior with an example using our previous code: <img src="image-300.png". And finally, update our code : <img src="image-280.png". Still, the updated code is not fully optimized for all devices yet. Let’s update our code example: <img src="image-280.png". srcset=" image-300.png
Generate your own madlibs in the demo ; Look through the final code on Github ; Get a fully-built version set up in your accounts. We can use 11ty’s new Serverless mode to build them on request using Netlify’s On-Demand Builders to cache each Madlib. Netlify then caches that page on its edge CDN for each additional call.
HTML Processing Once a web page’s HTML file has been downloaded, the browser begins to process the contents line by line, translating code into the visual website that users interact with. It also opens up the possibility for more effective use of caching strategies, potentially enhancing load times further.
Performance needs to be built in starting at the code level, and user-centric metrics like time to interactive (TTI), total blocking time (TBT), and first input delay (FID) help you gauge how fast a website is. This frees up the browser’s main thread to run your own code. This is why performance is crucial when building websites.
More specifically, we’re going to talk about storage and UI differences, which are the ones that most often cause confusion to developers when writing Flutter code that they want to be cross-platform. Running Different Code On Different Platforms. In this article, we’re going to see some of those differences and how to overcome them.
