Notion-to-Hugo中的一万个坑
流程工具来源：Notion到博客的自动化更新
实现：Notion写作，自动转化为md文件，推送至博客仓库，并部署至博客。
踩到的坑
少文件了
报错：“notion/notion_news.ts(13,44): error TS5097: An import path can only end with a ‘.ts’ extension when ‘allowImportingTsExtensions’ is enabled.”
解决：除了复制workflow文件及仓库内/notion文件夹文件之外，还需要加入package.json和tsconfig.json文件。
创建不行，得连接
报错：Could not find database with ID”Database id”，Make sure the relevant pages and databases are shared with your integration
解决：创建Notion Database之后，进入Database（也是一个踩坑点，如果Database内联在文章中，文章的ID不能作为Database ID），右上角点击三个圆点，选择connection到之前所创建的API中，Database才能正常被读取
粗心大意失荆州
报错如下，需要Database内字段属性与NotionService.ts内属性一一对应
TypeError: Cannot read properties of undefined (reading 'created_time')

论学好英语的重要性
报错如下，其实原因是因为Database内字段名称与NotionService.ts不一致，但可以将相应行改成：const category=post.properties.category.select.name?post.properties.category.name:'default name'，当值为空时赋值'default name'
TypeError: Cannot read properties of null (reading 'name')

一些适配工作
正确读取Notion文章，但是Front Matter不能正确拉取：
- Hugo默认Front Matter分类名称为
categories - 记得在转化Front Matter的代码最后一段，
---前加入一个空行，保证Frontmatter被正确读取。 - 修改
date: ${date}为date: '${date}'，Hugo要求日期前后以引号包裹。 - Hugo要求时间格式为yyyy-MM-dd，其中月份为个位数时，如8月，写作“08”，因此需要修改时间格式化相关代码。
function formatDate(date: string | Date) {
date = new Date(date);
const month = (date.getMonth() + 1).toString().padStart(2, '0');
return `${date.getFullYear()}-${month}-${date.getDate().toString().padStart(2, '0')}`;
}
发生了什么？
报错：我也不知道怎么出现的，但写了个.gitignore 文件加入这两个文件就OK了。
千万不要尝试git add这两个文件，Gtihub Action跑出来的行数还挺吓人的。
Untracked files:
(use "git add <file>..." to include in what will be committed)
node_modules/
package-lock.json
nothing added to commit but untracked files present (use "git add" to track)
Error: Process completed with exit code 1.
Vercel你也来了
Vercel构建博客时报错，报错信息没存，用.vercelignore解决了，构建时忽略以下文件：
tsconfig.json
notion_news.ts
notion_post.ts
EnvService.ts
NotionService.ts
package.json
想起来再补
还有一些零零碎碎的其他问题但没有太大印象了，看报错内容就能意识到是怎么回事……
其他类似实现方案：
语雀/Notion云端博客写作，同步部署到Hexo/Vitepress/Confluence等多平台
