WeChat applet is a lightweight application that can run directly in WeChat without downloading and installing. Users can scan the code or search the name of the applet to enter it. The development of WeChat applets can use the official development tools provided by WeChat—WeChat developer tools, or use third-party development tools.
WeChat Developer Tools is a development tool officially launched by WeChat. It integrates functions such as development, debugging, preview, and release, and supports Windows, MacOS, and Linux systems. Developers can use HTML, CSS, JavaScript and other technology stacks in the tool for development. Developers only need to install the WeChat developer tools, and then they can create mini-program projects, code writing, debugging and previewing. Developers can simulate mobile phone screens of different devices and sizes through the simulator in the WeChat developer tools, so that developers can debug the applet.
In addition to WeChat developer tools, there are also some third-party development tools that can be used to develop WeChat applets, such as Visual Studio Code, Sublime Text, etc. These tools can support the development of WeChat Mini Programs through plug-ins, enabling developers to develop more efficiently and comfortably.
The development language of WeChat applets is mainly based on the front-end technology stack, including HTML, CSS, and JavaScript. Developers need to understand the use of the WeChat Mini Program framework and API, as well as basic concepts such as the life cycle and event mechanism of WeChat Mini Programs. The WeChat applet framework adopts the MVVM architecture, where V (view layer) is composed of WXML and WXSS, M (model layer) is composed of JavaScript objects, and VM (view model layer) is composed of WXS and event binding. The APIs of WeChat Mini Programs include basic APIs, interface APIs, network APIs, media APIs, open interface APIs, etc. Developers can choose to use them according to actual needs.
When developing WeChat applets, you need to pay attention to the following points:
1. Minimize the amount of code in the mini-program as much as possible, because the mini-program needs to run in the WeChat client, so the quality of the code has a great impact on performance.
2. The interface of the Mini Program should be as concise and clear as possible, and do not use too many animations and effects, so as not to affect the user experience.
3. The functions of the applet should be as practical as possible and simple to implement. Do not pile up too many complicated functions to prevent users from being unable to use them.
4. Mini Programs need to comply with the WeChat Mini Program Development Specifications, including code style, naming conventions, component usage specifications, etc., to facilitate collaboration and maintenance among developers.
In short, the development of WeChat applets can use official development tools provided by WeChat, or third-party development tools. The development language is mainly based on the front-end technology stack. It is necessary to understand the use of WeChat applet framework and API. Pay attention The amount of code, the interface is simple, and the functions are practical. The development threshold of WeChat Mini Program is low, which is suitable for beginners and the development of small projects.
