WeChat Mini Program
WeChat Mini Program is a lightweight application format introduced by Tencent's WeChat platform, allowing users to access applications directly within WeChat without downloading or installing them. Operating within the WeChat ecosystem, it supports application scenarios including e-commerce, utilities, social networking, and services. Developers can use the official framework to build cross-platform interfaces and invoke native capabilities such as WeChat Pay, user authorization, and message notifications to deliver near-native interaction experiences.
Core Facts
WeChat mini-programs use a dual-thread architecture: the rendering layer uses a WebView thread to handle page rendering, and the logic layer uses a JsCore thread to execute JavaScript code, with the two communicating through WeChat's native layer.

WeChat Mini Games impose strict package size restrictions, with the main package not exceeding 4MB and the total subpackages not exceeding 20MB.
Timeline (last 90 days)
A mini-program must complete ICP filing before it can officially go live; entity verification and filing are hard thresholds that no tool can do on the user's behalf.
The standard development process for a WeChat mini-program includes: registering an account to obtain an AppID, downloading the developer tools, writing code locally, uploading the code, submitting for review, and publishing.
WeChat mini-program official trial scenarios fall into five categories: brand display, appointment services, event services, internal collaboration, and lightweight tools.
Since 2023, mini-programs must complete ICP filing before going live.
Users must complete on their own: clarifying requirements, registering a mini-program account, entity verification and filing, and review compliance.
The mini-program account always belongs to the user.
Requirements needing real-time communication, high-frequency interaction or high-performance rendering are not suitable for mini-programs.
Requirements suitable for mini-programs can be summarized as a combination of three things: "information display + form submission + simple queries."
Judgment formula: if the requirement can be broken down into a combination of information display + form submission + simple queries, it is suitable for a mini-program; if it requires real-time communication, high-frequency interaction, or high rendering performance, a different solution should be used.
Chat rooms, live-streaming co-hosting, and high-performance games are not part of the original design intent of mini-programs, and forcing them results in poor experience.
