Walkthrough

This update introduces a new reactive variable popShow and a corresponding function to toggle its value in the Vue component of the index page. It also modifies the Vite configuration to dynamically adjust the page overflow style based on popShow. Additionally, there are updates to type declarations and template handling to support this functionality.

Changes

File Path	Change Summary
playground/src/pages/index/...	Added popShow variable, handleChange function, button to toggle popShow, and new CSS style for long-block.
playground/src/uni-pages.d.ts	Updated URLs to include a leading slash.
playground/vite.config.ts	Modified UniLayouts call to include teleportRootEl with dynamic page overflow style.
src/context.ts	Added a conditional block to handle teleportRootEl in the Context class.
src/types.ts	Updated ResolvedOptions interface to include teleportRootEl property.

In the land of code, where changes bloom,
A rabbit hops, dispelling gloom.
With popShow toggles and styles anew,
The pages now dance in a vibrant hue.
🐇✨ The code evolves, a joyous spree,
With every change, more harmony.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

hi，感谢 PR, 当前的实现不是很优雅，如果是我的话，我应该会直接支持类似如下的方法（也许还有更好的），需要 @ModyQyW 来讨论下~

// 约定一个特殊的 slot，（不知道能不能实现）
<template>
    <template #layout:after>
        <page-meta />
    </template>
	<template #header>
        layout 的 header 插槽
    </template>
	<view>...page code</view>
    <template #footer>
        layout 的 footer 插槽
    </template>
<template>

正好，顺便可以直接支持一下不使用 uni-layout 组件的情况下直接使用 layout 的插槽？

我的想法大致和这里一致。我感觉这里应该是写错了，不是 #layout:after 而是 #layout:before（ 必须是页面第一个元素）。如果可以，同时支持 #layout:before 和 #layout:after 会更好。可以先尝试一下看看，不确定能不能实现🤔
