Building a Mini Program backend involves several key steps: domain name configuration, backend service development, UI development, and publishing. Mini Program platforms require server domain names to have an ICP filing and support the HTTPS protocol. Therefore, domain name configuration includes registering and filing a domain name, and deploying an SSL certificate. Backend service development involves deploying and publishing the services that your Mini Program depends on. UI development uses the Mini Program's developer tools and the APIs provided by your backend service to handle data interaction and build the user interface. For self-built solutions, domain and backend configuration pose significant challenges in terms of complexity, reliability, security, and cost.
