微信小程序开发的完整流程：需求分析、UI 设计、前后端开发、测试、审核上架，一篇讲清楚。
Complete WeChat mini-app development process: requirements, UI design, development, testing, and store submission — all in one article.
需求阶段 小程序适合轻量级、高频使用的场景：扫码点餐、预约服务、会员卡、简易电商。不适合重交互、长时间使用的场景（那该做 App）。在决定做小程序之前，先问自己三个问题：用户会每天打开吗？核心功能能在 3 个页面内完成吗？是否依赖微信/支付宝生态？ 设计要点 小程序有自己的设计规范：底部 Tab 不超过 5 个，页面层级不超过 10 层，首屏加载时间不超过 3 秒。设计要简洁，用户打开就能用，不需要学习成本。 我们建议使用微信官方的设计资源库（WeUI），保持与微信生态的一致性。同时注意适配不同屏幕尺寸，使用 rpx 单位代替 px。 开发技术栈 原生开发用微信开发者工具 + WXML/WXSS/JS。但如果你的项目同时需要支持微信、支付宝、抖音等多个平台，推荐使用跨平台框架： uni-app：基于 Vue 语法，一套代码编译到多个平台，国内社区最活跃 Taro：基于 React 语法，京东出品，适合 React 技术栈的团队 iDev 团队主要使用 uni-app，因为它与我们的 Vue 技术栈一致，开发效率最高。 后端对接 小程序的后端通常是一个 RESTful API 服务。我们用 Spring Boot 或 Node.js 提供 API，通过 HTTPS 与小程序通信。关键点： 域名必须备案并配置 SSL 证书 登录认证使用微信的 wx.login 获取 code，后端换取 openid 支付集成使用微信支付 SDK，注意签名验证和回调处理 审核与上架 微信小程序审核通常 1-3 个工作日。常见被拒原因： 功能不完整（有入口但页面为空） 类目不匹配（电商类需要营业执照） 诱导分享或关注 虚拟支付未使用微信支付（iOS 限制） 建议提前准备好营业执照、类目资质、隐私政策等材料，避免反复审核浪费时间。 上线后运营 小程序上线不等于成功。你还需要：流量入口设计（二维码、公众号菜单、搜索关键词）、数据埋点和分析、用户留存策略（模板消息、会员体系）、持续的功能迭代。
Requirements Phase Mini-apps suit lightweight, high-frequency scenarios: scan-to-order, booking services, loyalty cards, simple e-commerce. Not ideal for heavy interaction or extended use (that calls for a native app). Before deciding to build a mini-app, ask yourself three questions: Will users open it daily? Can the core function be completed within 3 pages? Does it depend on the WeChat/Alipay ecosystem? Design Guidelines Mini-apps have their own design standards: no more than 5 bottom tabs, no more than 10 page levels, and first-screen load time under 3 seconds. Design should be clean — users should be able to start using it immediately without a learning curve. We recommend using WeChat's official design resource library (WeUI) to maintain consistency with the WeChat ecosystem. Also ensure adaptation across different screen sizes using rpx units instead of px. Development Tech Stack Native development uses WeChat DevTools + WXML/WXSS/JS. But if your project needs to support WeChat, Alipay, Douyin, and other platforms simultaneously, cross-platform frameworks are recommended: uni-app: Vue-based syntax, one codebase compiling to multiple platforms, most active community in China Taro: React-based syntax, by JD.com, suitable for React-stack teams The iDev team primarily uses uni-app as it aligns with our Vue tech stack for maximum development efficiency. Backend Integration Mini-app backends are typically RESTful API services. We use Spring Boot or Node.js for APIs, communicating with the mini-app over HTTPS. Key considerations: Domain must be registered and configured with SSL certificates Login authentication uses WeChat's wx.login to get a code, exchanged for openid on the backend Payment integration uses the WeChat Pay SDK — ensure proper signature verification and callback handling Review and Launch WeChat mini-app review typically takes 1-3 business days. Common rejection reasons: Incomplete features (entry points exist but pages are empty) Category mismatch (e-commerce requires a business license) Inducing shares or follows Virtual payments not using WeChat Pay (iOS restriction) Prepare business licenses, category qualifications, and privacy policies in advance to avoid wasting time on repeated reviews. Post-Launch Operations Launching a mini-app doesn't equal success. You also need: traffic entry design (QR codes, official account menus, search keywords), analytics and data tracking, user retention strategies (template messages, membership systems), and continuous feature iteration.
