Fetching data from the server - Learn web development
originally page loading on the web was simple — you'd send a request for a website to a server, and as long as nothing went wrong, the assets that made the web page would be downloaded and displayed on your computer.
... less data is downloaded on each update, meaning less wasted bandwidth.
... to speed things up even further, some sites also store assets and data on the user's computer when they are first requested, meaning that on subsequent visits they use the local versions instead of downloading fresh copies when the page is first loaded.
... you can test the fail case yourself: make a local copy of the example files (download and unpack the can-store zip file).

Perceived performance - Learn web development
perceived performance the perception of how fast your site loads and how responsive feels to user interaction is vitally important; even more important that actual download time but difficult to quantify.
...in other words, first download everything you're going to actually show, but only the stuff you are actually using, then download the rest.
... if you're downloading all the assets in the end, the weight of all your assets hasn't improved -- in fact, you may need to add some code -- but because the download of non-immediately necessary assets are delayed in a manner that is not perceptible the the user, the user will feel like the download was faster.
... conclusion by turning as much of the download, render and wait time into active phases and reducing any passive waiting, even if the objective measurements stay the same, the user will feel like the content downloaded, rendered, and responded more quickly.

What is web performance? - Learn web development
this includes the following major areas: reducing overall load time: how long does it take the files required to render the web site to download on to the user's computer?
...the download of additional assets linked to from the index file is generally sequential, based on source order, but this can be manipulated and should definitely be optimized, realizing that some resources block additional downloads until their content is parsed and executed.
...this is the process that the browser uses to construct the web document once the files have been downloaded from the server.

Progressive web app structure - Progressive web apps (PWAs)
server-side rendering (ssr) means a website is rendered on the server, so it offers quicker first load, but navigating between pages requires downloading new html content.
... client-side rendering (csr) allows the website to be updated in the browser almost instantly when navigating to different pages, but requires more of an initial download hit and extra rendering on the client at the beginning.
...to have the javascript "operational", however, it has to be downloaded in its entirety.
... the streams api allows developers to have direct access to data streaming from the server — if you want to perform an operation on the data (for example, adding a filter to a video), you no longer need to wait for all of it to be downloaded and converted to a blob (or whatever) — you can start right away.

Progressive loading - Progressive web apps (PWAs)
to fix that we can, for example, add defer to javascript files: <script src="app.js" defer></script> they will be downloaded and executed after the document itself has been parsed, so it won't block rendering the html structure.
...when you include <img> elements in your html, then every referenced image will be fetched and downloaded during initial website access.
... it's not unusual to have megabytes of image data to download before announcing the site is ready, but this again creates a bad perception of performance.

How the Web works - Learn web development
when a client device wants to access a webpage, a copy of the webpage is downloaded from the server onto the client machine to be displayed in the user's web browser.
...basically, when data is sent across the web, it is sent as thousands of small chunks, so that many different web users can download the same website at the same time.
... if websites were sent as single big chunks, only one user could download one at a time, which obviously would make the web very inefficient and not much fun to use.

From object to iframe — other embedding technologies - Learn web development
these were considered the height of coolness in the mid to late 90s, and there was evidence that having a webpage split up into smaller chunks like this was better for download speeds — especially noticeable with network connections being so slow back then.
... now let's look at an <object> example that embeds a pdf into a page (see the live example and the source code): <object data="mypdf.pdf" type="application/pdf" width="800" height="1200" typemustmatch> <p>you don't have a pdf plugin, but you can <a href="mypdf.pdf">download the pdf file.
...they do still tend to be popular in some circles, but it is much better to link to them so they can be downloaded or read on a separate page, rather than embedding them in a webpage.

Introducing asynchronous JavaScript - Learn web development
that means that the following (pseudocode) wouldn't work: let response = fetch('myimage.png'); let blob = response.blob(); // display your image blob in the ui somehow that's because you don't know how long the image will take to download, so when you come to run the second line it will throw an error (possibly intermittently, possibly every time) because the response is not yet available.
...in this case the callback is waiting on the xhr call to finish downloading the resource (using the onload event handler) before it passes it to the callback.
...so you could have different actions to run on the response downloaded, such as processjson(), displaytext(), etc.

Video and Audio APIs - Learn web development
our finished example will look (and function) something like the following: getting started to get started with this example, download our media-player-start.zip and unzip it into a new directory on your hard drive.
... if you downloaded our examples repo, you'll find it in javascript/apis/video-audio/start/ at this point, if you load the html you should see a perfectly normal html5 video player, with the native controls rendered.
... icon fonts are very cool for many reasons — cutting down on http requests because you don't need to download those icons as image files, great scalability, and the fact that you can use text properties to style them — like color and text-shadow.

CSS performance optimization - Learn web development
the browser can paint the page once it has downloaded the css and built the css object model.
...by splitting the css into multiple files based on media queries, you can prevent render blocking during download of unused css.
...when the browser sees a style sheet it knows that it only needs to apply it for a specific scenario, it still downloads the stylesheet, but doesn't render block.

The "why" of web performance - Learn web development
and it isn't just the time taken to download that is a major problem.
...our example 22.6 mb cnn.com experience would cost about 11% of the average indian's daily wage to download.
...(see how much your site costs to download.) improve conversion rates reducing the dowload and render time of a site improves conversion rates and user retention.

Properly configuring server MIME types - Learn web development
examples of mime types are: text/html for normal web pages text/plain for plain text text/css for cascading style sheets text/javascript for scripts application/octet-stream meaning "download this file" application/x-java-applet for java applets application/pdf for pdf documents technical background registered values for mime types are available in iana | mime media types.
...an executable program should not be executed on the user's computer and at most should cause a dialog to appear asking the user if they wish to download the file.
...this bypassed the normal download dialog resulting in internet explorer guessing that the content was an executable program and then running it on the user's computer.

in presence of an accept-ranges header, the browser may try to resume an interrupted download, rather than to start it from the start again.
... none no range unit is supported, this makes the header equivalent of its own absence and is therefore rarely used, though some browsers, like ie9, it is used to disable or remove the pause buttons in the download manager.

Save-Data - HTTP
a value of on indicates explicit user opt-in into a reduced data usage mode on the client, and when communicated to origins allows them to deliver alternative content to reduce the data downloaded such as smaller image and video resources, different markup and styling, disabled polling and automatic updates, and so on.
... note: disabling http/2 server push (rfc 7540, section 8.2: server push) might be desirable too for reducing data downloads.

HTTP range requests - HTTP
partial requests are useful for large media or downloading files with pause and resume functions, for example.
...in some apps, download managers disable their pause buttons in that case.

async function - JavaScript
consider the following code: function getprocesseddata(url) { return downloaddata(url) // returns a promise .catch(e => { return downloadfallbackdata(url) // returns a promise }) .then(v => { return processdatainworker(v) // returns a promise }) } it can be rewritten with a single async function as follows: async function getprocesseddata(url) { let v try { v = await downloaddata(url) } catch(e) { v = await downloadfallbackdat...
...it returns null if processdatainworker rejects with an error: async function getprocesseddata(url) { let v try { v = await downloaddata(url) } catch(e) { v = await downloadfallbackdata(url) } try { return await processdatainworker(v) // note the `return await` vs.

Web app manifests
unlike regular web apps with simple homescreen links or bookmarks, pwas can be downloaded in advance and can work offline, as well as use regular web apis.
... the web app manifest provides information about a web application in a json text file, necessary for the web app to be downloaded and be presented to the user similarly to a native app (e.g., be installed on the homescreen of a device, providing users with quicker access and a richer experience).

Web Performance
javascript performance best practices javascript, when used properly, can allow for interactive and immersive web experiences — or it can significantly harm download time, render time, in-app performance, battery life, and user experience.
...or it can significantly harm download time, render time, in app performance, battery life, and user experience.

Graphic design for responsive sites - Progressive web apps (PWAs)
this is because in general mobile devices will have less processing power and bandwidth available, so you want to reduce the processing and downloads.
...so when the page is loaded on a mobile device, the mobile will only download the mobile assets, and not the desktop resource assets.

Mobile first - Progressive web apps (PWAs)
having it included in the "600 pixels or wider" media query means that narrow screen devices won't read that media query, so they will not waste their time and bandwidth downloading that image.
...modernizr is a good choice as it not only includes a feature detect for just about everything (css, html5, some other bits besides), it is also fairly reliable, and you can create your own custom version with only the feature detects you need in it, using the modernizr download builder.

The building blocks of responsive design - Progressive web apps (PWAs)
yes, you want the images to be contained inside the app ui whether you are using it on desktop or mobile, but you should also consider that mobile apps have much smaller viewport dimensions available than desktop apps, so you should try to give mobile devices a smaller image to download.
...let's look at a quick example: header { height: 300px; width: 100%; background: url(images/small-header.jpg) center; } @media all and (min-width: 480px) { header { background: url(images/large-header.jpg) center; } } this means that mobile browsers only download the mobile background image asset — not the desktop mobile assets — because they fail the media query tests and therefore ignore the media queries.

Caching compiled WebAssembly modules - WebAssembly
caching is useful for improving the performance of an app — we can store compiled webassembly modules on the client so they don't have to be downloaded and compiled every time.
...additionally, it handles creating a database to cache the compiled wasm modules in, attempts to store new modules in the database, and retrieves previously cached modules from the database, saving you from having to download them again.

WebAssembly Concepts - WebAssembly
additionally, the cost of downloading, parsing, and compiling very large javascript applications can be prohibitive.
... since javascript has complete control over how webassembly code is downloaded, compiled and run, javascript developers could even think of webassembly as just a javascript feature for efficiently generating high-performance functions.

Modules - Archive of obsolete content
