WeChat Mini Program: Introduction to WeChat Mini Program

1.What is a mini program?
A mini program is an application that can be used without downloading or installing. It realizes the dream of having an application "at your fingertips". Users can open the application 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. 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 mini programs can do what most APPs can do, 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 APP is as follows: Go to the APP store or major application markets to search, download, install apps and other operations. At the same time, we also have to deal with some mobile phones There are a series of issues such as traffic, mobile phone space, mobile phone hardware, etc., and 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. What are the development tools and data dictionary (development documents) of the mini program?

Each component and API will be discussed 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 applet 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 that opens is as follows:

2) Click Add Project and follow the prompts to fill in the Apple ID, project name, and project directory content. . If you don’t have an Apple ID, just select None.
