WeChat mini program is an application that does not require downloading and installation. It realizes the dream of having applications "at your fingertips". Users can open applications by scanning or searching. It also embodies the concept of "use and go", and users do not need to worry about installing too many applications. WeChat "mini programs" can provide developers with WeChat-based development components such as forms, navigation, maps, media, and location, allowing them to build an HTML 5 application in WeChat web pages. At the same time, WeChat has also opened interfaces such as login and WeChat payment, so that this "mini program" can be connected with the user's WeChat account.
