Installation

Usage

Hexo will run the generator automagically when you run hexo serve or hexo generate. 😏

Using the default settings, the content.json file looks like the following structure:

meta: {
  title: hexo.config.title,
  subtitle: hexo.config.subtitle,
  description: hexo.config.description,
  author: hexo.config.author,
  url: hexo.config.url
},
pages: [{ //-> all pages
  title: page.title,
  slug: page.slug,
  date: page.date,
  updated: page.updated,
  comments: page.comments,
  permalink: page.permalink,
  path: page.path,
  excerpt: page.excerpt, //-> only text ;)
  keywords: null, //-> it needs settings
  text: page.content, //-> only text minified ;)
  raw: page.raw, //-> original MD content
  content: page.content, //-> final HTML content
  author: page.author,
  categories: [{
    name: category.name,
    slug: category.slug,
    permalink: category.permalink
  }],
  tags: [{
    name: tag.name,
    slug: tag.slug,
    permalink: tag.permalink
  }]
}],
posts: [{ //-> only published posts
  title: post.title,
  slug: post.slug,
  date: post.date,
  updated: post.updated,
  comments: post.comments,
  permalink: post.permalink,
  path: post.path,
  excerpt: post.excerpt, //-> only text minified ;)
  description: post.description, //-> only text minified ;)
  keywords: null, //-> it needs settings
  text: post.content, //-> only text minified ;)
  raw: post.raw, //-> original MD content
  content: post.content, //-> final HTML content
  author: post.author,
  categories: [{
    name: category.name,
    slug: category.slug,
    permalink: category.permalink
  }],
  tags: [{
    name: tag.name,
    slug: tag.slug,
    permalink: tag.permalink
  }]
}],
categories: [{ //-> Posts categories index ;)
  name: category.name,
  slug: category.slug,
  permalink: category.permalink
}],
tags: [{ //-> Posts tags index ;)
  name: tag.name,
  slug: tag.slug,
  permalink: tag.permalink
}]

hexo.util.stripHTML is used to get only clean text for excerpt and text fields.

Settings

You can customize settings in _config.yml.

Defaults

Default settings are:

jsonContent:
  meta: true
  dafts: false
  file: content.json
  keywords: undefined
  dateFormat: undefined
  pages:
    title: true
    slug: true
    date: true
    updated: true
    comments: true
    path: true
    link: true
    permalink: true
    excerpt: true
    keywords: false
    text: true
    raw: false
    content: false
    author: true
  posts:
    title: true
    slug: true
    date: true
    updated: true
    comments: true
    path: true
    link: true
    permalink: true
    excerpt: true
    keywords: false
    text: true
    raw: false
    content: false
    author: true
    categories: true
    tags: true

Keywords

keywords options extracts keywords from excerpt.

Setting the root keywords option will automatically reflect to pages.keywords and posts.keywords. But you can ignore one by setting it to false explicitly.

It is powered by michaeldelorenzo/keyword-extractor, NPM package to create a keywords array from a string by removing stopwords.

So, the setting value should be a valid language from its options parameters.

# exemple 
jsonContent:
  meta: true
  keywords: french

If it don't support your language, no worry! It's disabled by default.

Date formats

dateFormat option sets an output format for datetime objects date and updated.

It is powered by moment, so any string accepted by format method can be used.

# exemple 
jsonContent:
  meta: true
  dateFormat: DD/MM/YYYY

If not defined, default format is the JSON.stringify result for Date objects.

Output

Sections

By default, the JSON output includes meta, pages and posts sections. If only one of these sections is enabled by config, the json output will consist of a single array.

For example, the following config enables only posts, showing title, date, path, and text fields:

# exemple 
jsonContent:
  meta: false
  pages: false
  posts:
    title: true
    date: true
    path: true
    text: true
    raw: false
    content: false
    slug: false
    updated: false
    comments: false
    link: false
    permalink: false
    excerpt: false
    categories: false
    tags: false
    author: false

The result JSON will look like this:

[{ //-> only published posts
  title: post.title,
  date: post.date,
  text: post.content, //-> only text minified ;)
  path: post.path
}]

Excluding fields

You can exclude meta, pages or posts contents from output JSON by setting meta, pages, or posts to false.

To exclude individual fields from pages or posts output, set its config values to false.

Drafts

By default, drafts are automatically skipped from indexing.

If you want to include drafts, set drafts: true:

# exemple 
jsonContent:
  drafts: true

Skip indexing

Any post or page protected with password will be automatically skipped from indexing.

You can also exclude a specific post or page by setting hidden: true on front-matter.

To exclude specific paths or tags, use ignore lists. Any path or tag which contains at least one of the listed substrings will be skipped from indexing. For example:

# exemple 
jsonContent:
  ignore:
    paths:
      - path/to/a/page
      - url/to/one/post
      - an-entire-category
      - specific.file
      - .ext # a file extension 
    tags:
      - tag1
      - tag2

Also, you can set hidden: false to override all the rules mentioned above.

Custom file name

By default, the output file is content.json, but is possible to customize the file name:

# exemple 
jsonContent:
  file: custom-file-name.json
