HTML is an older and polished markup language, used for structuring and presenting content for the World Wide Web. Blessed with JavaScript and CSS, HTML5 creates a standard strategy for Web programming that result into Web apps development. Comes with effective new features, HTML5 brings some spark in the Web programming paradigm shift and creates an exceptional websites with a neat coding. In fact after some of the excitement, it loses its native-app performances on the web. Although, we have enjoyed some new tags and APIs of HTML5 for many years, now it is time to quit it as several limitations also come with this markup language..

HTML5 isn’t able to sort out every problem, although it is well-known for its extraordinary capabilities. Some of its extra features are compelled and can develop web apps dreadful competitors for native apps, but points like limitations of local data storage, politics, security issues, synchronization challenges, etc. spreads water in our expectation. We know all the technologies come with some cons. Let’s discuss about hard-core realities about HTML5 that should be considered before starting web development process.

Nothing owed by The Cloud:

Users are blaming HTML5 for the structural problems happened with the storage of data in the cloud. In actual way, cloud is one of the important portions of the vision that helps in installation process of software and backing up data. Developers have an idea that Web app data storage is handled by the servers, so it is not wise to blame over the HTML5 local data storage. Although, this matter is not fixed by the HTML5, but it ensures that local data cached on your browser will be stored in the cloud for better security.

Limited Storage of Local Data:

One of the easiest ways to cache data for Web apps on your computer is through the local databases that hidden in the browser. Such database is also best for enhancing performance and saving bandwidth for those, who want to offer desktop like data functionality in their browser. But, there is a restriction; one can’t enjoy the same functionality with desktop apps. HTML5 data storage capabilities are considered as an essential addition, but it is restricted to move stored data to another machine, back it up, make copies or open it with a different app. In such case, you can see your updated database on the latest browsers on your machine, but you didn’t browse it or move it anywhere else.

Local data can be handled:

Users can’t able to access the local data, but while they are dealing with client data, it creates problem to the central website. Users find difficulty in such situation so they either switch browsers or machines. To tackle such situation, many developers are using local data storage for caching short-term content, so user didn’t face any problem while synchronization. Additional, developers also think about the local database’s security. Even, developer can’t able to search tool any tool for editing the local data and upgrade it.

Incompatibilities of Format proliferate:

The introduction of <audio> and <video> tags are indicated by the HTML5 that looks simple as image tags. You just have to place in the URL and the data is streamed by the browser. You find it an easy one, why I was searching basic audio files that supportable with all the major browsers? We can’t say it is the HTML5 committee’s mistake that various video and audio format doesn’t show the perfect result. Even, developers also try to plop the function canPlayType, but it dint work as well.

Security is a Dreadful:

The main issue with client-side computing is that users have to manage the codes running on the machine. The managing of web apps codes becomes easier, if browser comes with a great debugging tool. People, who are inquisitive about to know the structure of social media, can easily watch the code by adding breakpoints with a JavaScript debugger like Firebug. It is one of the best ways to learn how to operate website, but looking to the security issue, it is zero. To fight with security issues, one can use JavaScript tools like Google Web Toolkit, which is more difficult than standard compilers. But, the JavaScript Deminifier work more accurately than other security tools. With all above discussion, we get to know that client-based HTML5 apps can’t be trustworthy; one should have to aware of its capabilities.

No Prioritization For Web Workers:

In HTML5, web workers are the most interesting factors that operate browsers just like an OS without copying the features of OS. Web workers are the helpful factors as developers can divide their coding working among them by separating the CPU hogs. Now, developers don’t have to depend on copious JavaScript delay, wait, and pause commands. One of the great advantages for developer is they don’t have to manage workload according to priorities. Users can able to track the whole scenario of Worker objects to see the creation. But, the problem is after navigating the targeted page, the system become slower.

Difficult to sync offline apps:

The capability of using Web apps offline is greatly improved by the HTML5 local data storage. But, data synchronization causes the great problem. One cannot able to save data to the cloud while she/he is offline. Difficulty in synchronization also occurred while one can switch browsers or use a different machine for reproduces the copies. In addition to, clock also becomes unsynchronized that results into difficulty in finding the latest saved data. Such type of problem is also connected with the native apps. But in such case, users can responsible for synchronization and sorting out the problem by dealing with file names and change dates. In order to deal with such kind of problems, programmers have to manage by using version control systems. Apart from this, developers also gain huge knowledge for managing the synchronization of HTML5 Web apps.

Executions are browser-dependent:

HTML5 is the best markup language, but on other side, execution of any programming tactics doesn’t work properly. There are some objects and tags implemented by programmers for feature-rich HTML5 application development however, it doesn’t create planner a dream come true. Additional, many complaints regarding the failure of browser occurs because of the structure of the API. The browser-dependent disputes are the hardest truth that cause problem in making feature-rich HTML5-based Web app.

Above given are some of the hidden realities of HTML5 that creates a big dilemma while development. Although HTML5 is mostly adopted markup language, developers should also take care of its cons.
