The impact of 5G on the development of Web front-end and the future prospects of front-end engineers

The advent of the 5G wave has attracted worldwide attention, and various countries are vying for its dominance. Its impact on the software industry is huge and far-reaching, and may even lead to a reshuffle of the industry and the rise and fall of many technical jobs. So we developers have to pay attention to it.

What impact does 5G have on web front-end development?

There are posts about 5G in major online forums, and it is said that the theoretical download speed reaches 1.25G per second. The local files of a front-end project usually do not exceed 100M, and the largest files are multimedia, pictures and videos. More dynamic files will be transmitted through the image server.

Normally, it takes 2-3 seconds to open an APP homepage using the current 4G network. When you open the page for the first time, you need to wait for it to load. If there are long pictures or videos, it will take longer. There are also some backend database queries. If there is a large amount of data, it will take longer. Let’s not talk about the backend. Today we are only discussing the frontend. So far, we are still discussing how to achieve better performance optimization. At the beginning of a project, we need to select technology, build a cache mechanism, and deeply compress project files, etc.

The project's optimization methods seem to have reached a bottleneck. No matter how we optimize, if there are a large number of files and multimedia resources loaded, it will inevitably cause jamming. No matter whether it is the current Internet giants BAT, no matter how excellent their developers are, and how advanced their hardware support is, the software they make cannot be opened in seconds.

With the arrival of 5G, all these problems will be solved. If you still keep the traditional page style, with the speed of 5G, these will be nothing. No matter what software you open, you don't need to wait. 5G does everything with zero delay. With this advantage, it will promote the real rise of the Internet of Things and artificial intelligence. In the future, there will be more human-machine integration, and autonomous driving will no longer be just a concept. The industrial chain of large factories will be replaced by robots. At that time, there may be super logistics companies, whether it is transportation or distribution, all replaced by robots.

Back to the front end, humans are never satisfied. Once a single page opens in seconds, the traditional single-page layout will disappear, and more cool animations will be added, as well as 3D models, such as today's 3D car viewing in used car software, 3D house viewing in rental software, AR augmented reality, VR virtual reality technology will all be added. By then, there will be more rise in the AR game field, remote virtual reality presentation services, current examples such as APP lipstick color trial numbers, etc., there will be more exaggerated and unexpected service experiences in the future. As for web front-end development, this brings a problem, Internet companies, outsourcing companies, IT product service companies. Each company cares about different things. Internet companies are generally technology-driven. Due to the guarantee of sufficient funds, they will use the most cutting-edge technology, and they will not let go of new things.

The page will be cooler, the functions will be richer, and the interactive effect will be better. However, with more things presented on the page, it is not enough to rely on one person. In the future, development will be more embedded. There will be a team dedicated to animation development. VR, 3D models, canvas components, etc. require third-party support. These are heavy applications that cannot be completed by one person. Therefore, programmers who develop business will be more responsible for architecture maintenance and module embedding in the future. There will also be people who specialize in animation development, model development, etc. Everything is a packaged throw interface waiting for you to call.

As these things increase, more browser compatibility issues will arise, and there will be a technical revolution in browsers. In the future, there will be many branch professions in the front-end field, which means greater job selection.

So in today's front-end environment, how can we improve our core competitiveness?

The following aspects must be learned:

• You can use frameworks, but you are not limited to them. Currently, Vue and React are still very popular, but remember to read more about the underlying source code and architecture design when using frameworks.
• JavaScript is the core of the front-end. As a basic skill, no matter how the tools or frameworks change, it is necessary to understand the underlying JavaScript and design patterns.
• Learn server-side development. The front-end gradually interacts with the server, but many people are still at the stage of writing pages and adjusting interfaces. Large companies or senior front-end engineers require you to have node development experience when recruiting.
• Understand front-end engineering. As web businesses become increasingly complex and diversified, front-end development has shifted from being primarily WebPage mode to being primarily WebApp mode. Front-end work requires collaboration among multiple people, and the maintainability, development quality, and standardization of the project must be considered.
