Practical Development of WeChat Mini Programs Part 1: Introduction to WeChat Mini Programs 1. What is a mini program? Mini program is an application that does not require downloading and installation. It realizes the dream of having applications "at your fingertips". Users can scan or search for them. The application can be opened. It also embodies the concept of "use and go", and users do not need to worry about installing too many applications. Applications will be everywhere and available at any time, but there will be no need to install or uninstall them. 2. What can the mini program do? At present, it seems that the mini program is a function that can do what most APPs can do! WeChat mini programs have provided us developers with a wealth of APIs and components, allowing us to build a fully functional application in WeChat. ##3. Since the mini program can do most of the APP What are the advantages of mini programs compared to native apps? 1) First of all, from the perspective of ordinary users, the normal process of obtaining an APP is as follows: Go to the APP store or major application markets To search, download, install apps and other operations, we also have to face a series of problems such as mobile phone traffic, mobile phone space, mobile phone hardware, etc. The process of using an APP is relatively cumbersome. In this way, the mini program does not need to be installed, saving traffic and time. Although it is not as good as the original mobile APP in some scenarios, after a comprehensive comparison, as a user, you will be more inclined to small programs, which have relatively more advantages. #2) Secondly, for developers, development is more convenient, takes less time, and requires less investment. For teams that operate small programs, the cost is even lower. Because developing an app can range from hundreds of thousands to several million. Because developing an app not only needs to support iOS but also Android, as well as hardware costs and labor costs, the costs are very expensive. Now this part of the funds can be saved and invested in operations. 4. Mini program development tools and data dictionary (development documents) What is it? Entrance to WeChat mini program development tools and development documents: https://mp.weixin.qq. com/debug/wxadoc/dev/?t=2017112 We will talk about each component and API later. First look at the development tools We can see that the official provides 3 versions of developer tools for download. We only need to click in and download according to the version of our system. Just like ordinary software installation, just select the installation path and install it step by step. Note: After downloading and installing the Windows XP 32-bit developer tools, it may not run. In order to avoid this kind of situation from happening, we recommend that you use Windows 64-bit system. 5. How to create a WeChat mini program project? 1) After the WeChat applet development tool is successfully installed, it can be opened on the desktop. If this is the first time you log in, you will be prompted to scan the QR code using WeChat to log in. This is not the first time I have logged in locally, so the page after opening is as follows: 2) Click Add Project and fill in the Apple ID, project name, and project directory content as prompted. If you don’t have an Apple ID, just select None. After clicking Confirm to add the item, the following page will appear:
