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. 

With the tutorials on Codelabs, you can learn how to build applications from scratch. Some of the tutorial categories include Augmented reality, TensorFlow, Analytics, Virtual Analytics, G Suite, Search, Google Compute Engine, and Google APIs on iOS. 

8. Color Tool

Color Tool makes it easy for web designers to create, share, and apply colors to their UI. It also measures the accessibility level for any color combination before exporting to the palette. The tool comes with 6 user interfaces and offers over 250 colors to choose from. 

The tool is also very easy to use. All you need to do is pick a color and apply it to the primary color scheme; switch to the secondary color scheme, and pick another color. You can also switch to Custom to pick your own colors. After you have selected all your colors, use the Accessibility feature to check if all is good before exporting it to your palette. 

9. Workbox

Workbox is a set of JavaScript libraries and Node modules. The JavaScript libraries make it easy to add offline support to web apps. The Node modules make it easy to cache assets and offer other features to help users build Progressive Web Apps. Some of these features include pre-caching, runtime caching, request routing, background sync, debugging, and greater flexibility than sw-precache and sw-toolbox. 

With Workbox, you can add a quick rule that enables you to cache Google fonts, images, JavaScript, and CSS files. Caching these files will make your web page to run faster and also consume less storage. You can also pre-cache your files in your web app using their CLI, Node module, or webpack plugin. 

10. PageSpeed Insights

PageSpeed Insights is a handy tool from Google Developers that analyzes the content of a web page, then generates suggestions on how to make the page faster. It gives reports on the performance of a web page on both desktop and mobile devices. At the top of the report, PageSpeed Insights provides a score that summarizes the page’s performance. 

11. AMP on Google

AMP pages load faster and also look better than standard HTML pages on mobile devices. AMP on Google allows you to enhance your AMP pages across Google. It is a web component framework that allows you to create user-first websites, ads, emails, and stories. One benefit of AMP is that it allows your web pages to load almost instantly across all devices and platforms hence improving the user’s experience. 

12. Window Resizer

When creating websites, it is important that developers test them for responsive design – this is where Window Resizer comes in. Window Resizer is a Chrome extension that resizes the browser window so that you can test your responsive design on different screen resolutions. The common screen sizes offered are desktop, laptop, and mobile, but you can also add custom screen sizes.

Many people dream of a career in web design, but it may actually be more attainable than you think.

There are countless online courses, of variable quality, with little to no academic structure; self-learning is an option, but it doesn’t come with a curriculum. Without a professional structure and a comprehensive curriculum your dream career might never be more than that.

But there is a practical, fast-track option to making a career in web design a reality, and that’s the Parsons Web Design and Development Certificate.

Built around the innovative teaching approach that Parsons is known for, you’ll learn human-centered design, explore the latest tools, evaluate techniques and approaches, and uncover the secrets of UX. The certificate even offers two distinct tracks, one for designers, and one for developers, so you can take control of your own future.

It’s one of the most creative approaches to a formal design education in the world, and what’s more, because it’s entirely online you can study from anywhere.

What Will I Learn?

Parsons offers a flexible curriculum to suit both designers and developers. There are two core courses, followed by three specialist courses.

learn human-centered design, explore the latest tools, evaluate techniques and approaches, and uncover the secrets of UX

The core courses cover the essentials of web and mobile design, plus JavaScript for designers. Each of the core courses lasts nine weeks. When you’ve completed them, you can opt for a design specialism or a development specialism. (You don’t have to make your choice until you’ve completed the core courses!)

If you prefer design work, you’ll spend a total of 21 further weeks learning mobile design patterns, studying emerging platforms, working with interactive typography, and mastering design systems.

If development is more your thing, then on the 21 week development track you’ll cover advanced HTML, CSS, and JavaScript, learn how to work with APIs, and finish up with experimental JavaScript.

To earn the Web Design and Development Certificate you need to complete the two core courses, plus three specialist courses within two years — a total of 39 weeks of study. Parsons recommend that you take two courses per semester, but it’s possible to complete the entire certificate program in one year.

Is This Really For Me?

Parsons Web Design and Development Certificate is a recognized qualification from a reputable institution that will stand you in good stead in future job interviews. But what’s more important, is the knowledge and experience you’ll gain from the course.

Thanks to the creative, flexible approach to learning, the certificate is suitable for designers and developers at any stage of their career

Thanks to the creative, flexible approach to learning, the certificate is suitable for designers and developers at any stage of their career.

If you’re just starting out, the certificate is a superb way of exploring the field, all the while building skills that will make you stand out to employers.

If you’re a print designer, or a programmer, the Web Design and Development Certificate is a great way to supplement your existing skills and make a lateral move into web work.

And if you’re a grizzled industry professional with decades of experience, you’ll benefit from the track you know least well; designers studying development, developers studying design. Not only will it open up new creative avenues to you, but you’ll find project management easier with a broader outlook on the web.

The best thing about the Parsons Web Design and Development Certificate is that because it’s made up of modules, you can still work part-time as you tick off the courses.

Why Choose Parsons?

Parsons College of Design is part of The New School, a New York-based university. Open Campus, the platform that will run the certificate, is the New School’s online system for pre-college, professional, and continuing education courses.

Thanks to Covid-19, most learning institutions are planning online-only courses for at least the next 12 months, so why not enroll in a program run by an institution that already excels at online teaching.

Innovative courses, underpinned by the creative approach to teaching that Parsons College of Design is renowned for, mean the design education you embark on this fall will be second to none.

Individual courses cost between $577 and $850, with the entire Web Design and Development Certificate costing just $3,704.

Dans des moments comme celui-ci, la raison d’être n’est pas seulement un mot, c’est une responsabilité. Chez SAP, nous tirons parti de nos ressources et de notre réseau pour des solutions pragmatiques et innovantes, sur la base de valeurs et d’un objectif communs, mais nous vivons également notre raison d’être à travers nos propres actions pour aider le monde à mieux fonctionner et améliorer la vie des gens.

 

Les employés et les équipes de l’entreprise se sont engagés de manière utile pour répondre à la crise actuelle et montrer que l’objectif est de vivre au-delà des revenus et des bénéfices. En mettant l’accent sur la santé, le bien-être, la main-d’œuvre qualifiée et la promotion de l’entrepreneuriat social et inclusif, notre raison d’être ne répond pas seulement aux objectifs de développement durable des Nations Unies (ODD des Nations Unies), mais permet également de prendre soin des personnes dont nous nous soucions le plus.
Les employés de SAP dans les pays nordiques et au Royaume-Uni ont développé diverses idées sur la manière de se soutenir mutuellement pendant la pandémie – en tant que collègues, clients, partenaires ou bénévoles pour les personnes dans le besoin. Que ce soit pour un usage interne, local ou international, leur aide ainsi que leur créativité n’ont pas connu de frontières.
Poussé par l’envie de renforcer sa communauté locale Ottershaw, l’employé de SAP Mark French a puisé dans son expérience et son savoir-faire technique et a créé un site Web qui relie les personnes dans le besoin avec des voisins et des bénévoles. Grâce à www.ottershawsupport.com , chaque résident peut s’inscrire facilement pour obtenir de l’aide ou en donner, en recueillant des ordonnances, en faisant les achats essentiels ou en fournissant une assistance et des informations par téléphone.
Un autre exemple de dévouement sans limite a été la mise en place par un autre collègue de SAP qui a soutenu l’idée de son ami de longue date et artiste graffeur Keith Hopewell ( SP: zéro ). SP:zero voulait créer une pièce de collaboration sous forme d’illustrations avec des artistes du monde entier, démontrant la croissance du virus sous son titre « Spread art, not the ‘Rrona ». Ils se sont vite rendu compte que cette collaboration pouvait également apporter une aide financière.
«J’ai eu l’idée de vendre les tirages et de les donner aux hôpitaux britanniques qui nous soutiennent», explique Jago Livingstone. Sous le nom de «No Toys Allowed», il a conçu une boutique en ligne pour faciliter l’accès à leurs dons de charité. Les résultats ont été étonnants : de plus en plus d’artistes se sont impliqués, avec un pic à 163 artistes dans 21 pays sur tous les continents.
Les employés de SAP dans les pays nordiques et baltes ont utilisé leur créativité pour promouvoir la santé, le bien-être et l’inséparabilité, malgré la distance sociale. Vingt-deux collègues SAP d’une équipe de prévente ont livré une vidéo thématique en tant que contribution du Nordic Customer Solution Advisory à un événement à venir sur le thème «We Rise Up». La vidéo révèle une histoire personnelle sur la façon dont ils gèrent la situation actuelle et sur la façon dont chaque individu « se relève » ensemble pour ses collègues, clients et partenaires.
«Parce que c’est ce que nous faisons en ces temps difficiles, c’est dans notre ADN», dit Gitte Winther Bruhn, résumant l’essence de leur idée et montrant une fois de plus que chacun peut agir pour le bien commun, même avec les actions les plus simples.

Contentful; Webster’s Dictionary defines “contentful” as… not found. Clearly someone made up this word, but that is not necessarily a bad thing.

The world of user experience metrics is moving quickly, so new terminology is needed. Largest Contentful Paint (LCP) is one of a number of metrics measuring the render time of content on a web page.

What is Largest Contentful Paint?

Google defines LCP as “the render time of the largest content element visible within the viewport.” For what we are talking about in this blog, we will consider “content” to be an image, typically a JPEG or PNG file. In most cases, “largest” points to a hero image that is “above the fold” and is one of the first images people will notice when loading the page. Applying optimization to this largest content is critical to improving LCP.

It is probably more instructive to view LCP relative to other metrics. For example, First Contentful Paint (FCP) and Visually Complete book end LCP.

Each metric has its pros and cons, but LCP is a happy medium. LCP marks when web page loading starts to have a substantial impact on user experience.

In Google’s opinion, to provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading. Poor values are anything greater than 4 seconds.

How Does Largest Contentful Paint Impact Lighthouse Scores and SEO?

LCP is now part of several “Core Web Vitals” scores that Google will measure in its ranking algorithm. Each of the Core Web Vitals represents a distinct facet of the user experience, is measurable in the field, and reflects the real-world experience of a critical user-centric outcome.

In the case of the overall Google Lighthouse score, LCP represents 25% weighting on the performance score of Lighthouse version 6.0. This makes LCP the most important Core Web Vitals metric in determining the performance score.

While Google has indicated that content is still the most important factor in SEO ranking, a better user experience (as measured by Core Web Vitals) will generate higher rankings in a crowded field. If there are many websites competing for the top search engine spots, then Largest Contentful Paint will play a critical factor in rankings.

How to Improve Largest Contentful Paint

Now that you know that LCP is important, what can you do to improve it by making content load faster? Google provides a number of suggestions, but the most effective technique is to optimize content for the device requesting it.

For example, a website includes an 800kb JPEG image that is intended for high resolution desktops. On a smartphone, that would be optimized down to less than 100kb, with no perceptible impact on quality. LCP can improve by more than 60% — or several seconds — through this single optimization.

Find Savings in Largest Contentful Paint by using Image Speed Test

Image Speed Test is a great tool offered by ImageEngine.io that provides an analysis of LCP improvement opportunities. Just paste in the URL of the web page you are interested in optimizing, and the test will show you:

  • Image Payload Reduction
  • Speed Index
  • Largest Contentful Paint
  • Page Load Time (Visually Complete)

It also provides a video of the web page loading with and without optimizations. Finally, it analyses each image to provide an estimate of payload savings. In this case, the “largest content” on the page is this image. With optimizations, the image payload is reduced by 94%. That delivers a huge improvement in LCP.

How Does ImageEngine Improve LCP

ImageEngine is an image content delivery network (CDN) service that makes image optimization simple. Basically, for each image on the page, the image CDN will:

  1. Detect the device model requesting the web page;
  2. Optimize the image in terms of size, compression, image format;
  3. Deliver via a CDN edge server that is geographically closest to the user.

ImageEngine improves web performance for every image on the page, including the largest. You can learn more about ImageEngine here, and also sign up for a free trial.

Best Practices: Preconnect

In addition to using an image CDN like ImageEngine, a few other best practices can improve LCP. Using the resource hints to provide a preconnect for your content can streamline the download process.

For example, putting the following link statement in the HTML will accelerate the download process. The link statement will make the browser connect to the third party as early as possible so that download can start sooner. ImageEngine’s optimizations make each image download smaller and faster, but preconnect save time in the connection phase.

Best Practices: Minimize Blocking JavaScript and CSS

When JavaScript or CSS is “blocking” it means that the browser needs to parse and execute CSS and JavaScript in order to paint the final state of the page in the viewport.

Any website today relies heavily on both JavaScript and CSS, which means that it is almost impossible to avoid some render blocking resources. On a general note: be careful with what kind of CSS and JavaScript is referenced inside the <head> element. Make sure that only the strictly necessary resources are loaded in <head>. The rest can be deferred or loaded asynchronously.

When looking to improve the LCP specifically, there are some practices worth looking into more deeply.

Inline Critical CSS

It is not an easy task, but if the browser can avoid making a request to get the CSS needed to render the critical part of the page – usually the “above the fold” part – the LCP is likely to occur earlier. Also you will avoid content shifting around and maybe even a Flash of Unstyled Content (FOUC).

The critical CSS — the CSS needed by the browser to set up the structure and important styles of the part of the page shown above the fold — should in-inlined. This inlined CSS may also refer to background images, which of course should also be served by an Image CDN.

Do Not Use JavaScript to (lazy) Load Images

Many modern browsers natively support lazy loading, without the use of JavaScript. Because images usually are heavily involved in the performance of LCP, it is best practice to leave image loading to the browser and avoid adding JavaScript in order to lazy load images.

Lazy loading driven by JavaScript will add additional latency if the browser first has to load and parse JavaScript, then wait for it to execute, and then render images. This practice will also break the pre-parser in the browser.

If an image CDN is used to optimize images, then the benefits of lazy loading become much smaller. Especially large hero images that are above the fold have a large impact on LCP and will not benefit from being lazy loaded with JavaScript. It is best not to make JavaScript a blocking issue for rendering images, but rather rely on the browser’s own ability to select which images should be lazy loaded.

You’ve been working away at your latest design project, and the client has given the go-ahead on your lovingly created digital concepts. Now it’s time to bring those designs to life, and you have a developer queued up to do just that.

So your part’s done, right? Not quite. You’re going to want to make sure your developer has the best head start they can in order to create the site as you imagined.

Below are a few tips to make that handover process a little easier.

Communicate to Make It Great

Get Talking

Scheduling a face-to-face meeting with your developer to talk over your project’s specifics and ambitions will help align your expectations and make the intent behind your concepts more clear. It’s quite likely they’ll even ask questions and request assets you haven’t even thought of yet!

It’s not just a one-and-done thing either, your developer’s going to have questions or requirements that arise as the project progresses. Deciding on a communication channel to allow easy discussion will help you both immensely.

Annotating Your Concepts

Developers might seem like magicians with the way they bring your websites to life, but they’re not clairvoyant! Annotating your concepts where advanced functionality is required reduces ambiguity and makes it more likely that your cool, quirky idea is going to make it to production. If it’s a feature that’s particularly unusual, you might want to find an example of a website or code sandbox that does something similar.

An example of Figma’s comment tool in use to make developer notes.

Figma and Sketch both have comment functionality in order to make annotations a little easier, also allowing multiple parties to comment. If dealing with PDFs, there is also an annotation tool available through Adobe Acrobat.

Specify the Basics

The basis of modern front end development revolves around DRY thinking. Some might argue thinking about code can be pretty dry, but we’re not talking about that – in this case, DRY stands for Don’t Repeat Yourself.  Most developers will tackle a project by starting with defining variables: what colors, font sizes, grid columns… anything that can be reused! Good, consistent design follows this same principle – although it’s a habit that can be hard to get going at first.

Tip: It’s always easier to define variables if this mentality is approached towards the start of the project!  

Colors

Make a style guide that specifies the colors you’ve used in your designs. Think about their logical applications to help signpost how they might work as a variable – for example, what colors did you use for paragraph text, hyperlinks and backgrounds? Did you consider colors to convey status messaging, such as successes, warnings and errors?

Typefaces

Which fonts have you used for your project? Is there a consistent set of font sizes you used throughout? If you haven’t already, maybe consider a ratio-based type scale – I like to use ModularScale to help with this.

Basic HTML Elements

Think about general styling for these basic html tags:

  • Paragraphs <p>
  • Headings <h1–h6>
  • Bullet lists <ul> and numbered lists <ol>
  • Emphasized text <b>, <strong> and <em>

Buttons

How about buttons and links? What should they do when they’re hovered over, focused (using the tab key on a keyboard) or disabled?

Forms Fields and Inputs

What should form fields look like? Is there any validation checking that should occur when a form is submitted?  How about checkboxes and radio buttons?

It’s unlikely that you’re going to be able to cover absolutely every single eventuality – allow your developer to use some common sense to fill in the gaps, and be available to them if they have any questions. In the words of John Maxwell and your aunt’s home office wall sticker, teamwork makes the dream work.

Get Your Favic-on

Favicons are widely recognized as the small icon that appears to the left of the site title on your browser’s tab bar. Nowadays, the application of your site’s favicon is much further reaching, showing up in Google search results and app tiles. There’s also extra theming options available, such as the ability to customize the color of Google Chrome Android’s browser bar color for your site.

Using a generator site such as realfavicongenerator takes the pain out of much of this decision-making, allowing you to upload specific graphics as desired, creating silhouettes of your icon for Windows Metro tiles and macOS Safari pins, and packaging everything into easy-to-use files and code.

 Compress Your Images

Nobody wants to load a 20MB image when they’re on a slow connection or a data plan – it pays dividends to plan ahead and downsize your images so that they’re production-ready for the web. If you’re worried image compression is going to harm your image quality, fear not – you can go a long way with image compression before quality is seriously compromised.

  1. Start by reducing the image resolution – for batch jobs, I use Adobe Photoshop’s image processor script to downsize images to fit 1920 x 1200 pixels
  2. Alternatively, if you’re working on a static project – where specific images will be used only in specific places – you could use your design software (nearly all mainstream UI software allows you to do this now) to export your images at 2x size to support devices with high pixel densities.
  3. I also convert my image color profiles to SRGB to ensure consistency across most modern display types (this one’s optional)
  4. I then take my newly downsized images and run them through imageOptim at 80% quality. Generally I would aim to get my images under 300kb – if there are any that are still significantly over this target once compressed, I’d run these through again at 70% quality (I wouldn’t recommend going lower than this, though).

Don’t forget you can also do this for PNGs! Enabling PNGCrush in imageOptim will let you significantly reduce the size of PNGs… just be ready for it to take a while.

Make Your Vectors SVG-Easy to Use

If your design contains graphics or illustrations you created using vector software, it can be used on the web as an SVG file. Usually, these files will be a lot smaller than JPGs or PNGs. You can export graphics in most (if not all) vector software in this format.

Optionally, you could use imageOptim or SVGOMG to compress the SVG code without sacrificing quality. Your developer might already use a script that does this automatically when processing the site for production, so it may be worth asking ahead.

Get Your Licenses in Check

If you’re using premium fonts, make sure you’ve purchased a webfont license so you can hand over the correct files to the developer. I’d recommend doing this sooner rather than later – although not often, occasionally web versions of fonts can have slightly different bounding boxes to their desktop counterparts, making it a real pain for developers to work with further down the line.

If you’ve been using samples of stock photos (or if you’ve been going crazy lifting whatever you can find on Google Images), make sure everything is kosher before you go live. Make sure you purchase licensed photos, and if certain photos you want to use require attribution, make the developer aware of this.

Do you want to implement an HTTP server, but do you not want to take any risk of writing a full-fledged HTTP server? Developing an HTTP server with full capability is not a trivial task. But Java has got a solution to this kind of problem. Java supports an in-built HTTP server. By just writing 100 lines of code, we can develop a somewhat-decent HTTP server that can handle HTT$$anonymous$$ET and POST requests. We can also leverage it to handle other HTTP commands as well.
