Some thoughts on cross end development of kbone and applet

Applets are a new mobile application format , It's a kind of dependence Web technology , But there are also hybrid solutions that integrate native application functionality . Some features of the applet help to fill in Web And native platforms , So applets are popular with some super applications .

It doesn't need to be installed , Support hot update .

Have more than one Web View to improve performance .

It provides some access to operating system functions through native paths ( The native interface ) Or data mechanism .

Its content is usually more trustworthy , Because the application needs to be verified by the platform .

from 2017 In, wechat launched a small program for the first time , After four years of development , Major Internet giants have launched their own small program application platforms , Small programs become real “ New Internet technology standards ”. By 2021 In the first half of , Breakthrough in the number of small programs in the whole network 700 m , among , Wechat applet is the mainstream of the industry , More than 430 m , The proportion is as high as about 61.43%.

What is? kbone？

Wechat official started to promote a new multi-terminal unified development tool ——Kbone.

According to the official introduction ,Kbone Is a dedicated wechat applet and Web End isomorphism solution . say concretely , Because the underlying model of wechat applets and Web Different ends , So if we want to put Web It is impossible to move the end code to the applet environment for execution .Kbone Was born to solve this problem , It implements an adapter , The browser environment is simulated in the adaptation layer , Give Way Web The end code can run in the applet without any changes .

because kbone It's about providing adapters to implement isomorphism , So its advantages are obvious ：

Most popular front-end frameworks can be found in kbone Up operation , such as Vue、React、Preact etc. .

Support for more complete front-end framework features , because kbone The bottom layer of the frame will not be deleted （ such as Vue Medium v-html Instructions 、Vue-router plug-in unit ）.

Common dom/bom Interface , Let user code do not need to make too big change from Web End to applet end .

When running on the applet side , You can still use the features of the applet itself （ Such as live-player Built in components 、 Subcontracting function ）.

Provided some Dom Extension interface , There are alternatives for interfaces that are not perfectly compatible with the applet side （ such as getComputedStyle Interface ）.

The advantages of official propaganda , In short ： Common DOM/BOM Interface , Let user code do not need to make too big change from Web End to applet end . The launch of this solution , Wechat also responds to the growing demand of developers in the market .

What situation to use kbone good

Officials also say , In fact, there have been many solutions about isomorphism in the industry , Each scheme has its own advantages and disadvantages , There is no perfect solution to all problems ,kbone It's the same thing . If the performance of small programs is particularly harsh , The official suggestion is to use native applet development directly ; In other cases, we can consider kbone.

Hybird App The good news for developers

Now small program development is popular ,Hybird The development of is being compared 「Native+H5」 and 「Native+ Applet 」 Two hybrid APP Development mode , Which is better . By contrast ,「Native+ Applet 」 There are still many benefits of the development model .
「Native+ Applet 」 The advantages of ：

• Cross platform capability , A set of codes can be iOS And Android Running on both platforms ;
• Far more than H5 Experience （ Support local cache ,Webview, There are rich components and support libraries ）;
• Can get more system permissions , Complete richer product design ;
• You can avoid DOM Let the cat out of the （ Do not use commonly used window Object and the document object ）;
• Effective reduction of package size , Save traffic and storage
• Service is no longer limited by distribution , Support hot update

If you add kbone This web Isomorphic solutions , Now many web application , Can try to migrate into applet applications , Let enterprises pay more attention to the implementation of business logic .

Cross end development combo ： Applet +kbone+finclip

kbone Or applet , It just meets the existing business processes in the social ecosystem App Medium to lighter 、 It is more in line with users' needs for fragmented time access on social platforms .

that App There is no meaning of existence ？ Not at all .

Web3, With “ De centralization ”、“ Privacy protection ” As the core of a “ Technology movement ”, If it works , Can be said to be “ A long time must be divided. ” Proof of . But for ordinary enterprises , It's still far away . The present , immediately , What can I do ？ The simple way is ：

Own your own App、 Have your own service 、 Have your own data , Master your own digital ecology

Have these things , It used to be a difficult thing . For ordinary small and medium-sized enterprises and even large enterprises, there is nothing IT Budget Department , Make your own App First, the technical threshold is high , Secondly, it is difficult to maintain , Thirdly, the operation capacity is low . therefore , The final effect is , The input-output ratio is very poor , Proprietary App The quality is not high 、 The promotion cost is high 、 The traffic is small , Do more harm than good . Last , Many enterprises have given up trying in this field .

The emergence of the technical form of applet , It can be said that these problems encountered by enterprises have been solved to a great extent - Low development threshold 、 Light weight 、 And media content can be intertwined to facilitate sharing 、 It has the convenience of social communication 、 Publishing is relatively easy 、 Strong digital connectivity … So quickly get the welcome of the market .

add kbone Isomorphic solutions , So imagine , There will be more and more web End applications have joined the trend of applet applications .

Autonomous Control App, There are still many benefits , First, it precipitates the stock of users , You can reach and operate more directly , A stronger sense of community ; secondly , Customer privacy data 、 Business data of business operation , Can get greater protection - Ownership of data assets , There is no doubt that it belongs to the enterprise rather than a third party . Domestic Internet connectivity supported and promoted by the state 、“ Antitrust ” In the situation of , Between platforms 、 Public social platforms and enterprises App The connection and jump between should be based on open standards , Then the applet will flow to App、App Jump back to applet , It's all possible .

On the market Applet container technology FinClip, You can make App It runs small programs , Or use Kbone Transformed web application .

FinClip Applet container technology , whatever App By introducing FinClip When the applet runs SDK To gain the ability to run applets , meanwhile , It also provides a background management system , Unified management of small programs on and off the shelf , And collecting and analyzing applet data , For developers , It is extremely convenient . Follow the development standards and specifications compatible with wechat applet , in other words , If you have developed a wechat applet , You can... Without changing a line of code , Put it directly into your App Inside , The operation effect is consistent with that on wechat , There is no need for additional secondary development and transformation , It saves a lot of labor costs .

FinClip Support a variety of terminals other than mobile phones , Include Linux、Windows、MacOS、 Kirin and other operating systems . It means , Multi terminal equipment such as TV 、 Visual screen 、 Flat 、 Vehicle mounted equipment 、 Smart TV can use small programs , The implementation of the applet “ A development , Run anywhere ”, Reach many traffic platforms at the same time , Not just limited to wechat Ecology .
