Xiaosou is one of many developers who are using mini programs to serve quarantined users during the pandemic.
“Epidemic Little search” is an epidemic service mini program launched by Ifan. It allows you to check the epidemic situation within a few hundred meters of you in the first time and avoid risks. With the latest epidemic map, users can view the progress of the epidemic in real time by setting their location.
Urgent project
As the novel Coronavirus pandemic began to spread in early 2020, where confirmed or suspected cases were detected, when they were detected, and where the patients had been, became a matter of utmost concern to the nation.
In short, everyone wants to know what’s going on around me and my friends and family to keep themselves and their families safe.
However, due to the sudden outbreak of the epidemic, the disclosed data may be true or false, and the release platform is different, making it difficult to query. In order to solve this problem, Affan decided to unify the review data and synchronize the epidemic data in the form of a map to the mini program, so that everyone can quickly check the epidemic information in their neighborhood.
That is why the epidemic search was born.
With the development of the epidemic
On February 6
Project approval, immediately set up a special group.
On February 7
The first version of the epidemic map has been officially released, with its core function allowing you to view the epidemic data around you in real time to prevent future outbreaks.
After the launch, users generally feedback that it is very practical, but the data in some areas is not accurate, we hope we can complete as soon as possible.
On February 8th
The project team is divided into two parts. One part focuses on solving data problems and integrating official data to ensure timely and accurate data updates. The other part began to optimize the map display based on user feedback, to make the case data display clearer, increase the exposure of epidemic sources, and supplement the epidemic feedback entrance, so that everyone can participate in the construction of the epidemic map.
The setting of the epidemic feedback entrance has been very effective. Over the next few weeks, we received over 30,000 feedback. Once again, I would like to express my thanks to the users who helped build the epidemic map in phase I.
On February 9th
After investigation, we found that a large number of users were not only concerned about the epidemic around themselves, but also more concerned about the epidemic around their relatives and friends. Therefore, our small program team started to develop the group map function.
Users can share the small program in the wechat group, and the members can share their location and the surrounding epidemic situation, so as to report safety and warn each other.
On February 11th
As the number of users increases, the demand comes one after another. Users are not satisfied with simply checking the epidemic situation, but also need to purchase epidemic prevention resources. In accordance with the principle of disclosing the core epidemic situation, we have also started to access some third-party services to facilitate the one-stop fight against the epidemic.
Among them, the “face mask alert” service received the most likes.
On Feb. 16
In the middle of February, new cases began to appear abroad. Our data team quickly adjusted and expanded the coverage of the epidemic search from the whole country to the whole world for overseas users.
Developing those things
The pandemic is spreading so fast that the first requirements for small procedures are:
- Complete development quickly in a short period of time;
- Stable service, can withstand sudden heavy flow impact.
We were able to launch the first version in two days, and the next two weeks of iterations were perfect for millions of hits. All benefit from knowing cloud’s full customization support for small programs, such as:
-
Simple and lightweight SDK, with cloud-aware elastic database, quickly realize the increase, deletion, change and check of data. This is also the core function of small programs can be quickly online; 👉 Development documentation
-
Out of the box know push, take you to play small program subscription message; 👉 upgrade subscribe message shall be known five details | combat tutorial
-
Efficient and stable cloud functions for implementing business logic that CRUD can’t handle, such as complex permission control, lottery, offline computing, data analysis, etc. Still only need to write JS code, the rest of the trouble to know the cloud. 👉 cloud function actual combat tutorial
Other features, such as operation background, data analysis, payment access, customer service message, small program code, built-in CMS, multi-platform support and fast access, will not be introduced here for space reasons.
Open the “epidemic small search” experience small program, ** if you are interested in the realization of any of the functions of the small program, please leave a message at the end of the article on the public account, we will select the most liked function, launch the article specifically to introduce how to achieve. **👉 I’d like to leave a message
