Utiliser FaceIO pour développer le module d'authentification d'utilisateur d'une application web basée sur l'IA.

Utiliser FaceIO pour développer le module d’authentification d’utilisateur d’une application web basée sur l’IA est une solution innovante et sécurisée. Découvrez comment cela fonctionne!

Comment développer le module de connexion d’utilisateur du projet d’application Web à l’aide de l’interface de service AI tiers

Dans le passé, le développement des systèmes d’informations web application a nécessité une fonction module d’authentification d’utilisateur indispensable. La fonction d’authentification d’utilisateur comprend l’enregistrement et l’authentification de connexion des utilisateurs. Dans les méthodes de développement passées, la manière courante de réaliser le module de fonction d’authentification d’utilisateur est d’utiliser l’e-mail et le SMS pour vérifier. Maintenant, de nombreux ordinateurs des utilisateurs sont équipés de caméras, qui peuvent pleinement utiliser la technologie d’intelligence artificielle de reconnaissance faciale pour réaliser l’authentification d’utilisateur. J’ai utilisé la bibliothèque JavaScript de FaceIO pour mettre en œuvre l’authentification d’utilisateur dans le projet web app.

Cet article présente principalement comment développer le module de connexion utilisateur du projet web application à travers l’interface de service AI tiers. Le code source du projet web application a été téléchargé sur GitHub et est basé sur le protocole MIT. Il n’y a pas de restrictions.

En tant qu’informaticien enthousiaste, j’ai trouvé que l’utilisation de la reconnaissance faciale pour l’authentification d’utilisateur était très pratique. En outre, j’ai également constaté que la base de données des services AI tiers était très riche et complète. Cela me permet de trouver facilement les informations dont j’ai besoin pour le développement du projet web application. De plus, ces services AI tiers fournissent également des API très pratiques pour intégrer leurs fonctions à mon projet. Grâce à ces API, je peux facilement intégrer la reconnaissance faciale à mon projet web application et réaliser l’authentification d’utilisateur.

PageSpeed Insights is a free performance measurement tool provided by Google. It analyzes the contents of a web page for desktop and mobile devices. It provides a single number score (from 1 to 100) that summarizes several underlying metrics that measure performance. If you have not run PageSpeed Insights on your website, then you should stop and do it now. It’s an important indicator of how Google scores and ranks your site.

If your PageSpeed Insights score is below 80, don’t panic. You are not alone. Many websites are not optimized for performance. The good news is that you can take steps that should immediately improve your score.

You will notice that PageSpeed Insights highlights issues that cause slow page loading. However, you might need more guidance to resolve these issues. Below, we walk you through how to resolve four common issues related to images. We also show you how ImageEngine, an image CDN, can simplify, automate, and deliver the best image optimization solution possible.

Performance Drives Google SEO Rankings

Why does the PageSpeed Insights score and performance matter? Isn’t SEO ranking all about content relevance, backlinks, and domain authority? Yes, but now performance matters more than it did a year ago. Starting in 2021, Google added performance metrics to the factors that impact search engine rankings. In a market where websites are constantly jockeying to match their competition’s pages (for content relevance, keywords, and other SEO issues), performance is making a difference in keyword search engine rankings.

What Are Core Web Vitals Metrics?

PageSpeed Insights relies on a set of performance metrics called Core Web Vitals. These metrics are:

Largest Contentful Paint (LCP): Measures the render time (in seconds) of the largest image or text block visible within the viewport, relative to when the page first started loading. Typically, the largest image is the hero image at the top of pages.

First Input Delay (FID): Measures the time from when a user first interacts with a page (i.e. when they click a link, tap on a button, or use a custom JavaScript-powered control) to the time when the browser is actually able to begin processing event handlers in response to that interaction.

Cumulative Layout Shift (CLS): Measures the layout shift that occurs any time a visible element changes its position from one rendered frame to the next.

Images and JavaScript are the Main Culprits

PageSpeed Insights breaks down problems into categories based upon how they impact these Core Web Vitals metrics. The top two reasons why you might have a low score are driven by JavaScript and images.

JavaScript issues are usually related to code that either blocks or delays page loading. For example, lazy-loading images might involve JavaScript that blocks loading. As a rule of thumb, do not use a third-party JavaScript library to manage image loading. These libraries frequently break the browser’s built-in image loading features. Lazy-loading may make above-the-fold images load slower (longer LCP) because the browser starts the download later and because the browser first has to execute the JavaScript.

Another JavaScript issue involves code that is large or unnecessary for the page. In other words, code bloat. There are good resources for resolving these issues on the web. However, in this blog, we will focus on image problems.

Images are a major contributor to poor performance. The average website payload is 2MB in 2021, and 50% of that is images. Frequently, images are larger than they need to be and can be optimized for size with no impact on quality…if you do it right.

Four Image Issues Highlighted by PageSpeed Insights

Largest Contentful Paint is the primary metric impacted by images. PageSpeed Insights frequently recommends the following four pieces of advice:

  1. Serve images in next-gen formats.
  2. Efficiently encode images.
  3. Properly size images.
  4. Avoid enormous network payloads.

That advice seems straightforward. Google provides some great advice on how to deal with images in its dev community. It can be summarized in the following steps:

  • Select the appropriate file format.
  • Apply the appropriate image compression.
  • Apply the right display size.
  • Render the image.
  • Write responsive image code to select the right variant of the image.

We call Google’s process the “Build-Time Responsive Syntax” approach. If you have a relatively static website where you don’t generate new pages or switch out images frequently, then you can probably live with this approach. However, if you have a large and dynamic site with many images, then you will quickly feel the pain of this approach. Google itself stresses that developers should seek to automate this image process. Why? Because the process has some serious workflow drawbacks:

  • Adds storage requirements due to a large increase in image variants.
  • Increases code bloat and introduces more code complexity.
  • Requires developers’ time and effort to create variants and implement responsiveness.
  • Requires logic to account for different browser’s support for next-gen image formats.
  • Doesn’t adapt to different contexts. It relies on best-guess (breakpoints) of what device visits the web page.
  • Needs a separate CDN to further increase delivery speeds.
  • Requires ongoing maintenance to adapt to new devices, breakpoints, image formats, markets, and practices.

Key Steps to Achieving High-Performance Images

Instead of using the Build-Time Responsive Syntax approach, an automated image CDN solution can address all of the image issues raised by PageSpeed Insights. The key steps of an image CDN that you should look for are:

  1. Detect Mobile Devices: Detection of a website visitor’s device model and its technical capabilities. These include: OS version, browser version, screen pixel density, screen resolution width and height, support for next-gen image and video formats. This is where ImageEngine is unique in the market. ImageEngine uses true mobile device detection to further improve image optimization. It has a huge impact on the effectiveness of the image optimization process.
  2. Optimize Images: An image CDN will leverage the device’s parameters to automatically resize, compress and convert large original images into optimized images with next-generation file formats, like WebP and AVIF. Frequently, an image CDN like ImageEngine will reduce the image payload by up to 80%.
  3. Deliver by CDN: Image CDNs like ImageEngine have edge servers strategically positioned around the globe. By pushing optimized images closer to requesting customers and delivering them immediately from the cache, it often provides a 50% faster web page download time than traditional CDNs.

Easy Integration Process for Image CDN

After signing up for an ImageEngine account and free trial, you will receive a Delivery Address. After adjusting your <img /> elements to include the Delivery Address, ImageEngine will start to pull the original images from your website (no need to move or upload them), automatically optimize them, and deliver them.

You can automate the addition of the Delivery Address to the img src tag by using plug-ins for WordPress and Magento. Developers can also use ImageEngine’s React, Vue, or Angular JavaScript frameworks to simplify the process.

Additionally, there are many ways to simplify implementation via adjustments to templates for many CMS and eCommerce platforms.

Results: Improved Performance, Better SEO

Most ImageEngine users see a huge improvement in LCP metrics, and consequently, a big improvement in the overall PageSpeed Insights score. ImageEngine provides a free demo analysis of your images before and after image optimization. In many cases, developers see improvements of many seconds on their LCP and Speed Index.

In summary, performance drives higher search rankings, and better UX, and increases website conversions for eCommerce. The steps you take to improve your image performance will pay for themselves in more sales and conversions, streamlined workflow, and lower CDN delivery costs.

Google resembles an iceberg: there’s the part above the water we can see and use everyday; there’s also the part beneath the water, that we don’t see and know little about.

While many of us are concerned about the aspects of Google we don’t see — the parts that threaten our privacy, or monopolize the web — there’s no denying that Google offers some amazing products and tools, many of them free, all from the convenience of a single login.

Today we’re going to take a look at 12 tools from Google that really do bring something positive to the table.

1. Polymer

Polymer is an open-source JavaScript library from Google for building web applications using Web Components. The platform comes with a ton of libraries and tools to help designers and developers unlock the web’s potential by taking advantage of features like HTTP/2, Web Components, and Service Workers. 

The main feature of Polymer is Web Components. With Web Components, you can share custom elements to any site, work seamlessly with any browser’s built-in elements, and effectively use frameworks of all kinds. Products like LitElement (a simple base class for creating fast, lightweight web components) and PWA Starter Kit make Polymer easy to use. If you like, you can build your app entirely out of Web Components.

2. Lighthouse

Google Lighthouse is an open-source, automated tool for improving the quality of web pages. The software allows you to audit web pages for performance, SEO, accessibility, and more. You can run Lighthouse using ChromeDevTools, directly from the command line, or as a Node module. 

To use Lighthouse in Google Chrome, just go to the URL you want to audit (you can audit any URL on the web), open ChromeDevTools, and click the Audits tab. After you have run the audit, Lighthouse will give you an in-depth report on the web page. 

With these reports, you will see which parts of your web page you need to optimize. Each report has a reference doc that explains why that audit is important and also shows you the steps you can take to fix it. 

You can also use Lighthouse CL to prevent regression on your sites. Using Lighthouse Viewer, you can view and share reports online. You can also share reports as JSON or GitHub Gists. 

Lighthouse also comes with a feature called Stack Packs that allows Lighthouse to detect what platform a site is built on. It also displays specific stack-based recommendations.

3. Google Analytics

Google Analytics is the gold standard of analytics services. Google analytics can be installed on your site for free with a small amount of JavaScript and allows you to see all kinds of details about your site visitors, like what browser they’re using, and where they’re from.

By using Google Analytics you can make decisions about your site based on science, and therefore be somewhat confident that the decisions you make will result in the outcome you are expecting.

4. Flutter

Flutter is Google’s UI toolkit for building natively compiled applications for mobile, web, and desktop from a single codebase. The toolkit is open source and free to use. The best part of Flutter is that it works with existing code. 

The toolkit has a layered architecture that allows for full customization, which results in fast rendering and flexible designs. It also comes with fully-customizable widgets that allow you to build native interfaces in minutes. With these widgets, you will be able to add platform features such as scrolling, navigation, icons, and fonts to provide a full native performance on both iOS and Android.

Flutter also has a feature called hot reload that allows you to easily build UIs, add new features, and fix bugs faster. You can also compile Flutter code to native ARM machine code using Dart native compilers. 

5. Google API Explorer

Google has a huge library of APIs that are available to developers but finding these APIs can be difficult. Google API Explorer makes it easy for developers to locate any API. On the Google API Explorer web page, you will see a complete list of the entire API library. You can easily scroll through the list or use the search box to filter through the API list. 

The best part of Google API Explorer is that each link to a reference page comes with more details on how to use the API. API Explorer is an excellent way to try out methods in the Monitoring API without having to write any code.

6. Puppeteer

Puppeteer is a project from the Google Chrome team. The platform enables web developers to control a Chrome (or any other Chrome DevTools Protocol based browser) and execute common actions, much like in a real browser. Puppeteer is also a Node library and it provides a high-level API for working with headless Chrome. It is also a useful tool for scraping, testing, and automating web pages. 

Here are some things you can do with Puppeteer: generate screenshots and PDFs of pages, UI testing, test Chrome Extensions, automate form submission, generate pre-rendered content, and crawl Single-Page Applications. 

7. Codelabs

Google Developer Codelabs is a handy tool for beginner developers and even advanced developers who want to improve their knowledge. Codelabs provide a guided, tutorial, hands-on coding experience. Codelabs’ site is broken down into several tutorial sessions on different topics.

Multiple tech news sites have reported that  event-stream , a popular JavaScript library with almost two million weekly downloads, contained malicious code for several weeks. It was first reported in a GitHub post last week, but developers were only able to decipher the purpose of the code yesterday. The code targeted users of the cryptocurrency wallet Copay, and was designed to steal Bitcoin and Bitcoin Cash.

GitHub user right9ctrl injected the malicious code in a package called flatmap-stream after offering to help maintain the library, according to a post on the Snyk security blog. Handing off control to other users happens frequently in open source communities, as the original authors and maintainers move on to other projects. Adding libraries as dependencies is also common in open source, although the  event-stream npm package hadn’t been substantially updated for about two years prior to September 2018, when flatmap-stream was first added. According to Ars Technica, the next phase took place on October 5, when malicious code was implemented to transfer the balances of Copay wallets to a server in Kuala Lumpur.
