Applet Overview

What is a applet? What can it do? What is the difference between mobile apps and what are the advantages? With these questions, let's start a small program journey ....

According to Mr. Long

 

My understanding is: simple and easy to use, small and beautiful.

A applet is a hybrid between a native app and a web app. By loading, the app is similar to the native app. Compared with native apps, applets are more lightweight, updated in real time, and cross-platform. Compared with web apps, Applet resources are offline and experience is smoother. The design goal of a applet is to make it as simple and efficient as possible for developers to develop services with a native APP experience.

For users, the installation package of the applet is <= 1 MB, and the download and installation are extremely fast. In terms of the current network speed, the installation package can be ignored, which is not obvious in the sense, at the same time, the cell phone memory is greatly liberated. Unified interface style, fast response speed, good user experience, followed by the design philosophy. Small programs are positioned in high-frequency application scenarios.

For developers, multiple platforms can be used for one development. Unlike developing a mobile APP, developing a new version of adond requires IOS. An APP with the same features requires two systems, with high development and maintenance costs. But the applet is attached to the running, as long as it is installed, you can use the application developed by the applet (open it directly ). Mini-programs provide detailed UI, operation, and other specifications, and are uniformly developed using the mini-program language. The development cycle is short and fast, and the development cost is relatively low. In particular, the compatibility problem has been solved, these are especially important for the MP products of start-up companies (Product Rapid Development is launched to the market for testing. From the business point of view, where users are and where users spend more time, they should be built ).

Overall advantages: Low download threshold, cross-platform, low development cost, smoother experience, and available payment functions

The limitations are:

1. The development is based on the Framework. Some functions are limited and other third-party plug-ins are not supported;

2. the applet page can only open five at the same time, which is difficult to support if the interaction process is long;

3. the size of a small package is limited to 1 MB (currently). All packages are applicable only to lightweight packages.

After talking about this, the entrance should still look at the circle of friends (split screen .... Long Brother holding home good man ?)
