With the advancement of digital community construction, residents’ demand for convenient and diversified community services is growing day by day. WeChat Mini Programs have become a suitable carrier for building community convenience service platforms due to their advantages, such as no need for download and installation, a large user base, and low development costs. Currently, community services face problems such as scattered resources, delayed responses, and non-standardized service processes, making it difficult to meet residents’ demands for efficient access to services. This paper combines the actual needs of community residents with the technical characteristics of WeChat Mini Programs, and explains the development process of the community convenience service platform from four aspects: demand analysis, system design, development implementation, and testing improvement. It clarifies the core functions and technical framework of the platform, providing practical references for improving the efficiency of community services and enhancing residents’ quality of life experience.
