wechat-miniprogram-skill — Claude Code skill for native WeChat Mini

What wechat-miniprogram-skill does

This skill sets the agent up as a senior developer working on native WeChat Mini Programs in JavaScript. The stated priorities are performance, code size and native compatibility. TypeScript and cross-platform frameworks are ruled out, so if your project runs on Taro or Uni-app the guidance will pull against your stack.

The rules cover the everyday mechanics. Logic uses ES6+ with arrow functions for this binding, and async APIs get wrapped in Promises or async/await. State changes go through this.setData(), with data paths recommended for partial updates such as this.setData({ 'list[0].text': 'new' }). In WXML every wx:for needs wx:key, and taps are bound with bind:tap or catch:tap. Layouts use rpx with BEM naming, and reusable logic should live in Component() rather than Page().

A separate section lists the traps. Dates break in iOS when the string contains hyphens, so they get replaced with slashes before new Date(). Tab navigation requires wx.switchTab, and the page stack caps at 10 — worth checking if your flows chain a lot of screens. Overlaying <canvas>, <video> or <map> only works with <cover-view>.
