Nowadays 微信小程序, it has become an indispensable 'medium' in our daily life, such as small programs for our travel, shopping, dining, social, entertainment and other activities. People are naturally more inclined to install an app than to install an app. Directly access a small program in WeChat, and our small program is extremely convenient to provide services for users;
With the outbreak of the epidemic, we have launched small programs such as health codes, vaccinations, health treasures, and national health, etc. in various places, allowing users to simply operate in the small programs, which has brought great convenience to our epidemic prevention work;
Zeng Ming, the head of the WeChat applet, disclosed the market data of the applet in 2021. The data shows that in 2021, the daily active users of WeChat mini-programs will exceed 450 million, the average daily usage will increase by 32% compared with 2020, the number of payment users of mini-programs will increase by 80%, and the unit price of customers will increase significantly compared with 2020.
Specifically, in 2021, more than 700 million users will use Mini Programs to enjoy medical services. "In addition to vaccination, nucleic acid and other epidemic prevention and control, there are thousands of hospitals that have access to mini-programs and use mini-programs to carry their medical services." Zeng Ming said.
Last year, a total of 750 million users were using the collaborative tools of Mini Programs, of which more than 100 million users enjoyed digital government services on Mini Programs.
Zeng Ming disclosed that the active mini-programs are now growing steadily, with an increase of 40% compared to 2020. Among them, the mini-programs with transactions have increased by nearly 30%, and 90% of the growth here comes from small and medium-sized businesses. You can see the whole mini-program. The ecology is growing healthily and vigorously.
Now our WeChat developers can also reach 300W, which shows the market and prospects of WeChat applet development. In fact, we can easily see the advantages of WeChat applet in front of traditional apps;
1. Development cost: App development needs to form a team for H5 development and also needs to embed Android/ios engineers. Although our front-end engineers can also develop app development, if it involves the adaptation of Android/ios, the development cost is still Relatively high, on the other hand, the WeChat applet does not need to consider Android/ios, but only needs to be based on WeChat support;
2. Release issue: If the application of a conventional app involves publishing to the software store, it will take a certain amount of time to review, especially It is more troublesome to publish ios apps to the App Store. In contrast to WeChat mini-programs, we only need to submit the mini-programs for review after development, which is very fast;
3. User experience: regular apps require our users to go to all applications in the mall and then Download and install, and our applet only needs to search for relevant applet in WeChat, we can completely avoid installing a lot of software on the mobile phone, and only need one WeChat;
Having said so much above, I believe that many people are already full of passion for WeChat applet development, and the blogger will also lead everyone to enter the WeChat applet together; in order to help everyone learn better, the blogger deliberately wrote Column [30 days to grasp the WeChat applet] I hope that through this column, I can help you master WeChat applet development; I will guide you through the development, launch, and use of the applet; let's start our WeChat applet development journey!
Forged weapons
We all know that we need soldiers' sharp weapons before going to war. In fact, we are preparing to learn a language.
Of course, our WeChat applet development is actually relatively simple, we only need to prepare our own WeChat development account and official WeChat applet development tools;
Some friends may ask, do we have to use our WeChat developer tools? Can I use other VS code or HbuilderX? In fact, it is not impossible. I also raised such a problem when I was working, but I think it is better for us to use professional tools to do professional things.
developer account
-
Official address: https://mp.weixin.qq.com/
-
We visit the official address above and click on register in the upper right corner
-
Choose applet
-
Then we can complete it according to the three steps above. After completion, we can visit the official website and log in; we can scan and log in directly through WeChat. This is the development console of our WeChat applet;
-
After successful login, we go to get the ID of our applet
WeChat Developer Tools
-
Visit the link https://developers.weixin.qq.com/miniprogram/dev/framework/
-
Here we choose the stable version, and choose the version according to your computer situation
-
Download it and install it. I am a mac here. In fact, our window is also relatively simple.
-
After installation it looks like this
-
The first time you open it, we need to scan and log in on WeChat.

A book lays a good technical foundation and easily plays with artificial intelligence. Unlimited. There are many application platforms for artificial intelligence, but many platforms need to be registered before they can be used. The technical source code involved in this book has module support files, which are unlimited and do not require registration. It is very convenient to use. Omnidirectional. For the main development fields of artificial intelligence: answering robots, image recognition, object recognition, speech recognition, video recognition and other aspects, there are principle explanations and application expansions, so that readers can fully open up their understanding of artificial intelligence technology.
Introduction
Different from similar books on the market, this book not only focuses on the popularization of theoretical knowledge, but also integrates technology into Python modules for experimental operations and demonstrations. The main contents of this book include: overview of artificial intelligence technology, face recognition technology, object recognition technology, video recognition technology, speech recognition technology, text recognition technology, blockchain technology, etc. The whole book synthesizes the practice of artificial intelligence technology in various modules, unifies the scattered technical points, and integrates the abstract principles with cases that adapt to the readers' thinking, so as to achieve a full understanding of the knowledge points.
This book is suitable for readers engaged in data science and AI.

In fact, our preparatory work is done here. We have obtained the ID of the WeChat applet and installed the tools we use to develop WeChat applet. Once again, there are many code tools that can develop WeChat applet, but it is still like As mentioned above, we try to use the most professional tools to do professional things; well, let's see you below! Lead everyone to create your first applet.
