Uniapp小程序MBG 开发踩坑日记

最近开发一套微信音乐小程序框架使用vue3,但还是要吐槽一下,有时候会突然报错,怎么也调试不好,过段时间自己又好了,这让开发者体验极差。下面说下遇到的一些问题

Extraneous non-emits event listeners (close) were passed to component but could not be automatically inherited because component renders fragment or text root nodes. If the listener is intended to be a component custom event listener only

如果使用vue2 子组件的暴露给父组件的写法会报这个警告。需要在vue3的写法,在emits中提前声明。

//vue2
this.$emit('close')

//修改
export default {
		name: 'popup',
		emits: ['close'],
        methods: {
			close() {
				this.$emit('close')
			},
		}
}
