类型

EditUrlFn

type EditUrlFunction = (params: {
  blogDirPath: string;
  blogPath: string;
  permalink: string;
  locale: string;
}) => string | undefined;

ReadingTimeFn

type ReadingTimeOptions = {
  wordsPerMinute: number;
  wordBound: (char: string) => boolean;
};

type ReadingTimeCalculator = (params: {
  content: string;
  frontMatter?: BlogPostFrontMatter & Record<string, unknown>;

接受的字段：

参数	类型	默认值	描述
authors	Authors	undefined	博文作者列表（或者唯一作者）。 更多阐释可以参见 authors 指南。 即使文章只有一个作者，也推荐用 authors 而不是 author_* 字段。

draft	boolean	false	Draft blog posts will only be available during development.

hide_table_of_contents	boolean	false	是否隐藏右侧的文档目录。
toc_min_heading_level	number	2	目录中显示的最小标题层级。 必须介于 2 到 6 之间，并且小于等于最大值。
toc_max_heading_level	number	3	目录中显示的最大标题层级。 必须介于 2 和 6。
keywords	string[]	undefined	关键词元标签，会变成 <head> 中的 <meta name="keywords" content="keyword1,keyword2,..."/>，被搜索引擎使用。

// An author key references an author from the global plugin authors.yml file
type AuthorKey = string;

// Social platform name -> Social platform link
// Example: {MyPlatform: 'https://myplatform.com/myusername'}
// Pre-defined platforms ("x", "github", "twitter", "linkedin", "stackoverflow") accept handles:
// Example: {github: 'slorber'}

一篇 Markdown 博文

Tags File

Use the tags plugin option to configure the path of a YAML tags file.

By convention, the plugin will look for a tags.yml file at the root of your content folder(s).

This file can contain a list of predefined tags. You can reference these tags by their keys in Markdown files thanks to the tags front matter.

Keeping tags consistent

Using a tags file, you can ensure that your tags usage is consistent across your plugin content set. Use the onInlineTags: 'throw' plugin option to enforce this consistency and prevent usage of inline tags declared on the fly.

Types

The YAML content of the provided tags file should respect the following shape:

type Tag = {
  label?: string; // Tag display label
  permalink?: string; // Tag URL pathname segment
  description?: string; // Tag description displayed in the tag page
};

type TagsFileInput = Record<string, Partial<Tag> | null>;

Example

tags.yml

releases:
  label: 'Product releases'
  permalink: '/product-releases'
  description: 'Content related to product releases.'

# A partial tag definition is also valid
announcements:
  label: 'Announcements'

# An empty tag definition is also valid
# Other attributes will be inferred from the key
emptyTag:

content.md

---
tags: [releases, announcements, emptyTag]
---

# Title

Content

Authors File

Use the authors plugin option to configure the path of a YAML authors file.

By convention, the plugin will look for a authors.yml file at the root of your blog content folder(s).

This file can contain a list of predefined global blog authors. You can reference these authors by their keys in Markdown files thanks to the authors front matter.

类型

The YAML content of the provided authors file should respect the following shape:

type AuthorsMapInput = {
  [authorKey: string]: AuthorInput;
};

type AuthorInput = {
  name?: string;
  title?: string;
  description?: string;
  imageURL?: string;
  url?: string;
  email?: string;
  page?: boolean | {permalink: string};
  socials?: Record<string, string>;
  [customAuthorAttribute: string]: unknown;
};
