Simple Tips for Designing a Browserless Web

browserless_ywf

Browserless web is best known as communication over the World Wide Web between programs rather than between people and the server programs at Web sites. Many people believe that in the future, program-to-program communication will be more popular, as it will generate more traffic than browser-to-Web site communication. Even though browser-to-Web site communication is program-to-program – the browser is a client program and the Web server is a server program on behalf of a Web site – this new program-to-program communication does not involve an interactive user. Application that orders fulfillment is likely candidates for the browser less Web.

Of course, there are also some pros and contras on the topic of native versus web experiences. Many are comparing its reliability and speed with the native app experience. Therefore, in this article, we will explain how to design and develop progressive web applications (PWAs) in brief, so that many can experience a browserless web. Hopefully, this article would be beneficial for web developers or web designers who want to create a more engaging web.

  • Instant Page Transitions

It’s an open secret that users do not want to wait. Therefore, you have to be able to get in and around an app quickly without making them wait for your content to load in each interaction.

Solved with PWA

In order to pass the Lighthouse checklist for a PWA, one must follow certain performance-enhancing guidelines. Then, the content will be cached behind the scenes and to make you feel like there is no loading event, content should be cached behind the scenes.

  • Perceived Performance

You might be surprised by knowing that the level of stress caused by mobile delays is pretty much the same as watching a horror movie. Therefore, a good app should not let their users wait for their content. Other thing like elements appearing asynchronously as the app loads should also be avoided.

Solved with PWA

With the “Add to Homescreen” PWA launch transition, you can have a visual bridge between loading and loaded content. This shows how “preloaded states” can increase the perception of speed and seamlessness. Through a well-designed PWA, you can mimic the end state of the page and by using lazy-loading to deprioritize elements that are out of view; you can make the initial loading seem faster.

  • Works Offline

People, who prefer to download native apps, mostly want to use the apps without constantly relying on an Internet connection in order for the apps to function properly.

Solved with PWA

To solve this problem, the page content will be cached behind the scenes, allowing it to be accessed where there would, otherwise be a lag  in the browsing experience, such as when entering a tunnel while driving.

  • Back Button

Android provides a back button through the device which makes some people think there is no need to replace the browser’s back functionality. In fact, most apps choose to offer a back button in the header as an “up” action that navigates within the hierarchical relationship between pages.

Solution

The only possible solution for this problem is to place the menu button in the top left with a back button once the user progresses past the initial page. It will be validated once we put this pattern in front of users. Once participants had progressed through the initial home page, you can ask them to navigate to a new section.

 Can We Use it in the Real World?

Of course you will need “Add to Homescreen” to develop into an accepted group of patterns. To get some best practices about browserless web, you can read the following practices:

Sticky Headers, Persistent Actions

With this sticker, visitors can understand about the importance of learning ability when introducing new patterns.  In fact, the main purpose of this sticker is to ensure that users can easily find crucial global actions.

Prompt Intelligently

As it is said that PWA’s will get full control when they want to prompt users, this makes “Add to Homescreen” installation increase.

Stress and Test

One of the most important validation processes is to do the stress test in multiple applications. This is because, in most cases, the pattern stood up well to the latest brand. For example, the Lancome’s PWA contains many calls to action, which, as a result, can help in identifying overflow menu as a great opportunity to simplify its user interface, while offering exclusives program.

Conclusion

Many believe that “Add to Homescreen” will offer users to a next level experience, which is more engaging and converting user. This is because, a more modern, app-like web can have more positive effects on engagements, as it meets user expectations of performance and design.

The only way to meet those expectations is by combining PWA performance enhancements with intuitive design patterns in navigation and app-like user experience.

8 Brilliant Tips for Developing the Applications for Internet of Things

Important Tips for Developing the Application for the Internet of Things_YWF

Before we go deeper with IoT, it is imperative to understand what Internet of Things (IoT) actually is. Basically, a platform enables the network, the smart device and user to get connected with the internet via a definite identifier. In general, IoT works on an embedded technology to communicate with all external environments. No wonder this thing has been seen as one of the revolutionary mobile app development trends in this generation, as it can manage everything right from an array of cohesive events to number of interconnected devices.

In fact, many have predicted that 2 billion devices will get connected to IOT by 2020, whereas the next five years $6 trillion is expected to be invested in IoT. This shows that Internet of Things have influenced a diverse set of industries to speak of, including the healthcare sector, the entertainment and gaming, automotive, home automation, and logistics. This is why IoT has a great potential in the future.

The Three Pillars of IoT

There are three major pillars which are important to note, regarding to the entire structure of the Internet of Things, such as:

  • Network: Generally network will perform similar function like router does in connecting the network to device. In this case, the devices are linked to the cloud. The infrastructure stationed at data centers will receive information. The things provide the data stream and also manage it. On the other hand, software helps to organize the things.
  • The things in themselves: it acts as Internet Gateway which is regarded as an Internet Gateway that helps other device communication through a single or many protocols. In fact, you won’t see a screen once the device gets connected to the network.
  • The cloud: it is a server that primarily aims for securing users confidential data. So, when users meet a critical juncture, the data will still get processed whereas the processing of a program usually happens during the concluding stages.

Tips for Developing Applications for IoT

Now, you have a better understanding about IoT and you may have lots of apps for the Internet of Things in mind. However, before you create one, you may want to know some factors that you can use as consideration, such as:

  1. Choose an Appropriate and Convenient Platform

The first step that every developer should do is to select the appropriate platform for the development process. One thing for sure, the platform should support the IoT applications and its components. Some platforms that are IoT proven and offer the scope to design the best in class apps are Ubidots, Xively or Thingworx. With the help of these platforms, you don’t have to start anything from the beginning.

  1. Consider the Industry for IoT Application

As stated above that Internet of Things has much widened and extended services, but there are still some fields that aren’t connected with Internet of Things. Therefore, you have to discover set of industries that can optimally connected such as healthcare, transportation, energy resources, sports, manufacturing etc. For instance, with IoT application, people can easily find transportation such as connecting buses or trains.

  1. Segregate Services from API Interface

Bear in mind that you need to separate the services from API interface while you are developing the apps for IoT. This will ensure you to have an app that runs smoothly on mobile and web desktop. You will surely get better opportunity once you manage your IoT applications well.

  1. IoT Data must be Secured Strongly

Every application developer knows about how important a strong secured environment is, especially to IoT data from the physical attacks. In fact, the security becomes more important when it comes to building GPS networks or banking apps.

  1. The Different Levels of IoT Apps

In order to understand the system and function of IoT applications, you have to know the various levels of IoT applications. Basically, there are four different layers; the devices, the ingestion tier, the analytics area and the end-user.

First of all, you have to consider the devices that you will be connecting. Then, you will see the infrastructure or the software receives data or organizes it. The next layer is all about data which actually is mainly processed with the help of analytics area. The last layer is about the end users for whom the app is getting developed.

  1. Keep an Eye on IoT Device Firmware Security

The difference between the Internet of Things from the traditional web and mobile apps is its hardware which is always apprehended to have security based issues in the firmware this is why it is essential to stay authenticated and signed before the update.

  1. Do not Neglect with Speed and Quality

You cannot comprise with the speed and quality at any cost when creating application for the IoT. Therefore, you have to focus on transforming the ideas into practice and provide stable working prototype.

  1. Ensure Scalability to the Application

It is important to build scalable applications since IoT is still a new concept. However, many believe that IoT is going to get bigger than ever with the time to arrive. In fact, having a good scalability will allow your app to remain in light for a long period of time.

In conclusion

Internet of Things is still considered as new comer in the technological area, but we will immediately see it is expanding and reached to a different height. This will surely help people access information easily and get connected one to each other at a  low price. On the other hand, it is also a challenge for the developers as it is different from other conventional methods.

Google Lighthouse for Measuring Mobile Site Speed

Lighthouse is a tool created by Google and was originally meant to audit Progressive Web Apps (PWA). In general, this tool will do four audits for accessibility, performance, progressive web apps and an extended list of best practices. With a flaky 3G connection on a slightly underpowered device, Google Lighthouse stimulates your mobile site visitors. The main purpose of Google Lighthouse is to increase a site speed through measuring page speed from a different, more realistic angle. This surely makes Lighthouse very recommended to any web developers and SEO services who aims for a faster loading Mobile site speed.  However, some people are more familiar with PageSpeed instead of Google Lighthouse, so what’s the difference between Page Speed Insights and Google Lighthouse?

PageSpeed Insights vs.Google Lighthouse

Right now, PageSpeed Insights is still the most popular analysis tool which can provide you with a nice score and a list of possible improvements. However, it hardly gives you an idea of the perceived loading speed of your site. Moreover, it also states that your site doesn’t follow the rules and therefore, it is slow for everyone. Here are the two most important things PageSpeed Insights looks at:

  • Time to above-the-fold load: This is the time that it takes to fully render the above-the-fold content of a page from the moment a user requests your page.
  • Time to full page load: This is the time that it takes to fully render the complete content of a page from the moment a user requests your page.

On the other hand, Lighthouse focuses on practical approach where it puts user experience front and center. Since it visits your site over a throttled 3G connection, it can predict what a real visitor would experience. Moreover, Lighthouse will check how and when it responds to input while PageSpeed Insights will just load your site. No wonder Lighthouse can easily find the exact moment when your content is ready to use.

What to Look for in Lighthouse Results?

The important point that users want to see and feel is that your site must be fast and must feel fast. In other words, users should be able to interact with your content as soon as possible. This is absolutely important for your SEO; therefore, you need to fix these issues. There are several metrics that Lighthouse uses such as follows:

  • First meaningful paint: This metric will determine how long content should appear on screen. The lower the score, the faster the page appears.
  • First interactive: it will also measure if a page is minimally interactive.
  • Consistently interactive: This measures when a page is fully interactive.
  • Perceptual Speed Index: This shows how quickly the contents of a page are visibly populated which also comes with a target loading time of <1,250 ms.
  • Estimated latency input: This measures how long your page will respond to user input.
  • Critical requests chain: It shows what resources are needed to initially render this page.

Even though Lighthouse is not as popular as PageSpeed, its functionality cannot be ignored. In fact, this is a worth to try tool for those who want to analyze their site speed. In fact, it is more fine-grained and gives you immediate feedback based on real-world usage.
