Background and solution

1、新增物料流程中，拆分物料，增加物料，合并物料，组件无法正常加载了
看了下合并物料的逻辑里面没有加 pacakges 字段，导致组件未能正常加载到 TinyLowcodeComponent 中，进入区块加载逻辑，从而报错

2、对于组件 snippets 的处理，之前的逻辑是只会添加一个 snippet 到component 指定的分组，有一些场景比如 upload 组件，可能会配置 按钮上传、拖拽上传、图片上传等不同用例，便于使用，这种情况目前的脚本无法处理

What is the current behavior?

拆分物料，增加物料，合并物料，组件无法正常加载了

Issue Number: #1158

What is the new behavior?

1、增加了 packages 描述
2、增加逻辑，对组件 snippets 中的每一项，如果 snippet 中定义了 category 则放到该分组，如果未定义，则取 component 定义的 category 放到该分组，如果都没有定义则放到默认的 其他分组

Walkthrough

This pull request updates the generateComponents function in the scripts/buildMaterials.mjs file by introducing a new packages array within the materials object. The array lists two component libraries, each containing properties like name, package, version, script, and css. In addition, the snippets array now includes a trailing comma and the handling of componentSnippets is enhanced to iterate over multiple snippets, grouping them by category. The overall control flow remains unchanged while improving the flexibility of component data management.

Poem

I’m a rabbit hopping along the code trail,
Adding libraries and tweaking details without fail.
Packages line up, snippets dance in groups,
Iterative loops and arrays form the troops.
With swift logic and a joyful heart so bright,
I celebrate these changes in pure delight!

96-113: Good addition of the packages array to support component loading.

This change addresses the issue where components couldn't be correctly loaded into TinyLowcodeComponent due to the missing "packages" field. The implementation includes two component libraries with all necessary properties for proper loading.

---

151-151: Nice improvement with default empty array.

Setting a default empty array for componentSnippets is a good defensive programming practice to avoid null/undefined errors when iterating over the array.

---

155-167: Successfully implemented support for multiple snippets per component.

This change effectively solves the problem of adding multiple snippets to a component. The logic now properly:

1. Iterates through each snippet in the componentSnippets array
2. Determines the appropriate category using a clear fallback mechanism
3. Either adds the snippet to an existing category group or creates a new group

The implementation aligns perfectly with the PR objective to support different use cases (like button upload, drag-and-drop upload, and image upload) for a single component.

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>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.
  • @coderabbitai help me debug CodeRabbit configuration file.

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.
