Suggested January 2024 What Is The App Shell Model In Javascript?

The App Shell Model is a design pattern that keeps a web app’s UI and data modules apart. Caching the user interface in this design may load content on the fly. This method is widely utilized in progressive web apps (PWAs) because of its many speed and user experience benefits.

Benefits of the App Shell Model in JavaScript Faster Load Times

The user experience is enhanced by reducing the time it takes for the program to load for the first time due to caching the app shell. Users have come to anticipate instantaneous response times from online apps, and any lag in response time will likely be seen as unacceptable. The App Shell Model achieves this separation between the UI and content by rapidly caching and loading the UI.

Enhanced Efficiency

The app’s shell is identical across all screens, so it can be readily improved for speed. Optimizing the app shell and boosting its speed is possible via lazy loading and code splitting by developers, and the end effect is enhanced load times and general user satisfaction.

Improved Performance Offline Capabilities

Users will have a more consistent and dependable experience because of the app shell’s ability to be cached and loaded even when not connected to the internet. Service Workers, a background-running JavaScript API, do this by snooping on network requests. Service Workers allow developers to cache assets and provide offline functionality, making the app shell and content accessible even when the user is not connected to the internet.

How to Implement the App Shell Model in JavaScript? Define the App Shell

A program’s user interface (UI) must have a foundational framework in place, which includes the layout, navigation, and other features shared by all pages and views. The app’s outer shell must be built to load quickly and keep the user interested by using optimized components and a consistent design.

Cache the App Shell

Service Workers, a background-running JavaScript API with network request intercept capabilities, are used to cache the app shell. Developers may cache the app shell and other materials with the help of Service Workers to provide a fast load time and a consistent user experience. The initial load time of the application may be sped up, and UI consistency is ensured across views and pages by caching the app shell.

Load Content Dynamically

The data is dynamically fetched and presented within the app framework. Webpack, a module bundler, can help since it employs code splitting and lazy loading to improve the app shell’s efficiency. Developers can keep the app shell quick and responsive while users switch between views and pages by loading material on the fly.

Optimize Performance

Developers may further enhance the app’s speed by optimizing the app shell. Lazy loading, code splitting, and other optimizations may help you get there. To keep the app shell quick and responsive, developers may utilize technologies like Webpack.

Provide Offline Capabilities

Service Workers may save the app’s shell in a cache to be loaded even when the user is not connected to the internet. Service Workers allow developers to cache assets and provide offline functionality, making the app shell and content accessible even when the user is not connected to the internet. This is especially helpful for PWAs because of their capability to function even in the absence of or with limited access to a network.

Examples of the App Shell Model in JavaScript Google Maps

Google Maps is a famous example of JavaScript that employs the software Shell Model. Google Maps’ user interface is constant across views and pages, making using the map and search features easy. We can keep the app zippy and responsive by dynamically loading material like location data and street view pictures.

Twitter Lite

Twitter Lite is a JavaScript App Shell Model progressive web app. By caching the app shell using Service Workers, we can guarantee that the UI will always load promptly and look the same across all views and pages. Tweets and user profiles, for example, are dynamically loaded to provide a fast and exciting user experience.


The ridesharing service Uber is another program that leverages the JavaScript App Shell Model. Thanks to its optimized components and uniform design, the app’s shell is built to wow with its speed and polish. The app’s responsiveness and interest are maintained via the dynamic loading of material, including ride data and user profiles.


The App Shell Model in JavaScript is a robust framework with the potential to enhance online applications’ speed and usability dramatically. Developers may improve the app’s speed by caching the app shell and removing unnecessary code by isolating the UI from the content.

Service Workers provide offline functionality so that an app may be used without a network connection. Developers may follow the abovementioned guidelines to successfully implement the App Shell Model in JavaScript, resulting in powerful and user-friendly online apps.

What Is An Avatar In The Metaverse?

No doubt by this point you have heard of Facebook turning into Meta and announcing a complete Metaverse. While having a lot of aspects to it, a thing that stood out to a lot of people is Metaverse Avatars. Designed to be a kind of representation with customization, Metaverse Avatars are something interesting to wait for. But what exactly is an Avatar in the Metaverse and what can you do with it? Find out answers to all that and more with this handy guide I’ve created for you. Let’s check out what is a Metaverse Avatar.

What Is an Avatar in the Metaverse?

While I will tell you what is an Avatar in the Metaverse, I do plan on discussing other surrounding topics. However, if you would rather just skip to it, use the table below.

What Is an Avatar?

If you’ve been on the Internet for some time, you must already be signed up for multiple social media accounts. Depending on the platform, users either upload their photos for their profile or create a 2D or 3D model of themselves for it. That is where our conversation begins. Put simply, an Avatar is an online representation of a user. This digital identity differs from person to person and can either be static or animated.

Want more specifics? Consider Bitmoji. Starting out as 2D emojis for users to use while talking to each other, these avatars have now turned 3D, and are used as your representations in a bunch of Snapchat games. Avatars continue to be the way many social media users use to replicate themselves online.. You can be almost anyone you want to be using an Avatar. You can shape it according to how you exactly are, customize its hairstyle, apparel, accessories, and much more. Chances are, you already have an Avatar or two and use them day today. However, an Avatar is much more than that too. Keep reading to find that out.

What Is an Avatar in the Metaverse?

However, a big difference here will be flexibility. While some avatars are restricted to only a single platform, a Metaverse avatar will be able to cross through different experiences in the entire Metaverse. So whatever avatar you create along with their appearance will easily carry over to different virtual worlds you will visit. The avatar then becomes your identity in the Metaverse.

Another big difference is the Metaverse Avatar’s flexibility. In order to incorporate such a wide area of usage, Meta is designing its avatars to be extremely realistic. So rather than just simple facial nods to capture movement, a Metaverse avatar will replicate the entire person and their body movements in order to give create a vivid feeling of the actual person being there.

What Will I Be Able to Do with This Avatar?

If you’re someone who doesn’t use Virtual Reality, you might be wondering. How can these Metaverse avatars be useful to me? A good answer to that is Meta CEO Mark Zuckerberg’s recently announcement stating that Meta avatars will now be expanding to Facebook, Messenger and Instagram.

Source: Meta

So if you’re someone who loves to be expressive on social media, you will be able to use these avatars in feed posts, stories and even use them as your FB profile picture. Avatars also help expand inclusion into other areas. Newly releasing avatars will also include the option to add Cochlear implants and other hearing aids. Furthermore, wheelchair avatars will also appear through the Meta ecosystem’s social media.

Is an Avatar Important to the Metaverse

It most definitely is. An avatar in the Metaverse is more than just a user’s created face. It most essentially becomes that user’s entire manifestation in the Metaverse. Therefore, whatever actions the avatar undertakes are directly driven by the user themselves. So apart from just playing a few games, all types of other activities including important financial ones will also be reflected onto the avatar and therefore the user. The Metaverse relies on this specific principle of User equals Avatar and hence cannot exist without it.

Types of Metaverse Avatars

While the type of avatars out there is plentiful in their creation and variety, the Metaverse will most likely focus on the following below:

1. VR Avatar 2. Full Body Avatar

How Can I Make My Own Metaverse Avatar?

While the Metaverse is still in its early stages, there are already companies out there offering the services of Avatar creators. Going with them, a user can create a fully personalized avatar that can be used to not only visit apps and games but also do even more intuitive things. We have an in-depth guide on this already on the way so stay tuned to learn how to create your own Metaverse avatar.

Are Other Companies Creating Avatars?

While a Metaverse avatar is surely exciting, Meta isn’t the only company on this path. Another tech giant to enter this race is Microsoft. Announcing Microsoft Mesh in late 2023, the company unveiled its own set of personalized 3D avatars and virtual spaces. Working on the same principle of realistic inclusion, users will be able to communicate using their avatars inside Microsoft Teams.

Moreover, the company has announced its set of facial movement tracking that will breathe life into these avatars along with full-fledged virtual environments. Like Meta, Microsoft’s focus is geared towards a mix of productivity in mixed reality coupled with using these avatars in the entertainment space. However, only time will tell how well these avatars come out to be.

Context Is The Killer App For The Digital Consumer

Context is the killer app for the digital consumer

As recently as a five years ago, it was relatively easy to segment the mobile market into business users and consumers. Business users had specific needs, as did consumers, and rarely did those needs intersect. Today, the idea of segmenting users into the classes of business vs. consumer is becoming archaic and to attempt that level of breakdown will lead to erroneous views of the market.

Today, it’s far less important to discuss the business user vs. the consumers and instead recognize that for the most part, they are one and the same. It’s not about business or consumer. It’s about PEOPLE. There is increasingly an overlap in how people interact with their devices and data and the result is that much of the information on users devices overlaps both business and personal information. For example, the typical users “buddy list” on their IM client will likely contain a combination of business contacts as well as friends and family. Look at a typical laptop and you will likely find many traces of personal data and entertainment co-existing with business information. Increasingly, business is reaching to the home and the reverse is happening as well and nowhere is this more of an issue than in the mobile arena.

For example, many IT departments allow users to select the mobile device of their choice or allow them to come from an approved list of supported platforms. Users are often not reimbursed for device fees but rather for some or all of the services associated. As a result, these devices are perceived as more personal than ever and are likely to have a different contextual use.

In the past, mobile was a dead space. You couldn’t call someone when you were away from home (unless there was a payphone about). One certainly couldn’t text or email in real-time to stay in contact. Content was limited to whatever small amount you could carry on your person, be it work, entertainment or the like. Today, we have moved beyond this point and mobility is a critical space, defined by that fact that it is the place that is neither work nor home (or school for students). Users increasingly find themselves in different contextual situations as a result and are looking for devices that can provide contextually relevant information to them as needed. At the airport, while waiting for a plane, that might mean checking flight schedules. It means being able to respond to business calls and emails. It might mean letting family members know of the delay and then listening to favorite music or watching a movie to distract from delay. Devices and services such as the SlingBox have totally evolved the concept of time shifting, to place shifting. That’s just the tip of the iceberg as consumers continue to connect their TVs, PCs and phones to both the Internet and each other.

Each of these circumstances involves seamlessly moving into the contextually relevant moment, finding, communicating or using the proper information or data and then shifting to the next moment. In short, there is no killer app for the digital consumer. It’s context that is the killer app. New devices today are finally allowing that contextual flow of circumstance and information to become a reality, and for consumers to begin to embrace them. It’s not just anytime but anywhere as consumers move their content from device to device, place to place and location to location. But there’s more. Next week, I’ll talk about what happens when you link all that together with social networks.

Deeper Learning: The Coaching Model

Today’s post is from Brandon Wiley from the Asia Society International Studies School Network (ISSN) . Brandon describes the ISSN approach to coaching teachers towards deeper learning for their students using the SAGE strategy.

Do these questions or questions like these sound familiar? Why does learning in many schools around the United States still looks very traditional, lacking the rigor and purposefulness required to prepare students for the 21st Century? Understanding exactly how to develop the knowledge, skills and dispositions students must possess to be successful in the 21st century has become a common discussion point in many schools across the United States and abroad. We express a desire to help our students become better problem-solvers, to be collaborative and to think critically. The truth is, as I reflect on my own time as an elementary and middle school teacher, I wonder sometimes if my instruction truly allowed for students to engage in deeper learning.

Why do we need to know this? Is this going to be on the test?

Instruction that embodies the characteristics of deeper learning certainly can answer the two questions posed above. Developing instruction that engages students with an issue of local or global significance, provides them an opportunity to apply content knowledge in a meaningful way and allows multiple opportunities for reflection, refinement and self-assessment all serve as ways to engage students in deeper learning. To make this all possible though, it’s important to help coach and support teachers as they plan and instruct.

Since 2003, Asia Society has worked in partnership with school districts and charter authorities to create the International Studies School Network (ISSN), a national network of over thirty design-driven schools serving urban, suburban and rural communities in seven states. The mission of each ISSN school is to create an environment for learning and development in which every student is prepared to succeed in college or other post-secondary education and to develop global competence. Global competence is best defined as a student’s capacity and disposition to understand and act on issues of global significance. Instruction that supports the development of globally competent student provides multiple opportunities to investigate the world, recognize and weigh diverse perspectives, communicate ideas and take action.

The core learning approach within each ISSN school is the Graduation Performance System (GPS), which provides clear criteria and a reliable process for students to produce work that demonstrates college readiness and global competence. In a practical sense, the GPS is an iterative process of helping teachers to plan rigorous performance-based learning tasks, deliver targeted instruction and assess student learning in an authentic way. It provides an opportunity for both the teacher and student to receive feedback, while reflecting on the learning experience. When working with teachers, coaching and support is necessary to help them in understanding how to create learning tasks that embody the elements of deeper learning. One strategy we have used to help guide their thinking is to ask them to reflect on the SAGE elements of a learning task:

Student Choice: The task calls on students to plan and assess their work over time through reflection. During the task, students are asked to make key decisions about the direction of their work, focus, and presentation. To support this, the task provides opportunities for teachers to deliver formative and summative feedback to the students throughout the learning process.

Authentic Context: The task provides an experience that resembles what adults do in the real-world. This requires students to communicate, collaborate, think critically, be creative, negotiate with other people, and use digital media in ways that support knowledge building.

Global Significance: The task fosters the capacity and dispositions to understand and act on issues of global significance. Ideally, the task stimulates students to build knowledge that is cross disciplinary.

Exhibition to an Audience: The task provides students with opportunities to showcase or present their work to an appropriate/relevant audience beyond the teacher and classroom. Students are provided opportunities to discuss their work and receive feedback that holds them accountable for their claims.

By helping teachers to identify explicit ways in which the SAGE elements can be developed in a learning task, strategic coaching has assisted them in thinking more deeply about the learning experience they are providing for students. These elements help ensure that students are more engaged in their learning, while giving them a purposeful way to apply 21st century skills. This coaching strategy is but one way we have attempted to help our schools ensure that students are engaged in deeper learning throughout the course of their school year.

The book was written and produced through collaboration between Asia Society and the Council of Chief State School Officers (CCSSO) EdSteps Global Competence Task Force.
