Fetching content

This module globally injects $content instance, meaning that you can access it anywhere using this.$content. For plugins, asyncData, nuxtServerInit and Middleware, you can access it from context.$content.

Methods

$content(path, options?)

• path
  • Type: String
  • Default: /
• options
  • Type: Object
  • Default: {}
  • Version: >= v1.3.0
• options.deep
  • Type: Boolean
  • Default: false
  • Version: >= v1.3.0
  • Fetch files from subdirectories
• options.text
  • Type: Boolean
  • Default: false
  • Version: >= v1.4.0
  • Returns the original markdown content in a text variable
• Returns a chain sequence

You can also give multiple arguments: $content('articles', params.slug) will be translated to /articles/${params.slug}

path can be a file or a directory. If path is a file, fetch() will return an Object, if it's a directory it will return an Array.

All the methods below can be chained and return a chain sequence, except fetch which returns a Promise.

only(keys)

• keys
  • Type: Array | String
  • required

Select a subset of fields.

const { title } = await this.$content('article-1').only(['title']).fetch()

without(keys)

• keys
  • Type: Array | String
  • required

Remove a subset of fields.

const { title, ...propsWithoutBody } = await this.$content('article-1').without(['body']).fetch()

where(query)

• query
  • Type: Object
  • required

Filter results by query.

Where queries are based on subset of mongo query syntax, it handles for example: $eq, $ne, $gt, $gte, $lt, $lte, $in, ...

// implicit (assumes $eq operator)
const articles = await this.$content('articles').where({ title: 'Home' }).fetch()
// explicit $eq
const articles = await this.$content('articles').where({ title: { $eq: 'Home' } }).fetch()

// $gt
const articles = await this.$content('articles').where({ age: { $gt: 18 } }).fetch()
// $in
const articles = await this.$content('articles').where({ name: { $in: ['odin', 'thor'] } }).fetch()

In order to filter in objects and array you need to enable nestedProperties, see configuration.

const products = await this.$content('products').where({ 'categories.slug': { $contains: 'top' } }).fetch()

const products = await this.$content('products').where({ 'categories.slug': { $contains: ['top', 'woman'] } }).fetch()

This module uses LokiJS under the hood, you can check for query examples.

sortBy(key, direction)

• key
  • Type: String
  • required
• direction
  • Type: String
  • Value: 'asc' or 'desc'
  • Default: 'asc'

Sort results by key.

const articles = await this.$content('articles').sortBy('title').fetch()

Can be chained multiple times to sort on multiple fields.

limit(n)

• n
  • Type: String | Number
  • required

Limit number of results.

// fetch only 5 articles
const articles = await this.$content('articles').limit(5).fetch()

skip(n)

• n
  • Type: String | Number
  • required

Skip results.

// fetch the next 5 articles
const articles = await this.$content('articles').skip(5).limit(5).fetch()

search(field, value)

• field
  • Type: String
  • required
• value
  • Type: String

Performs a full-text search on a field. value is optional, in this case field is the value and search will be performed on all defined full-text search fields.

The fields you want to search on must be defined in options in order to be indexed, see configuration.

// Search on field title
const articles = await this.$content('articles').search('title', 'welcome').fetch()
// Search on all pre-defined fields
const articles = await this.$content('articles').search('welcome').fetch()

surround(slug, options)

• slug
  • Type: String
  • required
• options
  • Type: Object
  • Default: { before: 1, after: 1}

Get prev and next results arround a specific slug.

You will always obtain an array of fixed length filled with the maching document or null.

const [prev, next] = await this.$content('articles')
  .only(['title', 'path'])
  .sortBy('date')
  .where({ isArchived: false })
  .surround('article-2')
  .fetch()

// Returns
[
  {
    title: 'Article 1',
    path: 'article-1'
  },
  null // no article-3 here
]

search, limit and skip are ineffective when using this method.

fetch()

• Returns: Promise<Object> | Promise<Array>

Ends the chain sequence and collects data.

Catch()

Checks if the .md file is exist in content directory or not.

It should be inserted after the fetch().

Example

const articles = await this.$content('articles')
  .only(['title', 'date', 'authors'])
  .sortBy('date', 'asc')
  .limit(5)
  .skip(10)
  .where({
    tags: 'testing',
    isArchived: false,
    date: { $gt: new Date(2020) },
    rating: { $gte: 3 }
  })
  .search('welcome')
  .fetch()
  .catch((err) => {
     error({ statusCode: 404, message: 'Page not found' })
  })
