inCategory

import { inCategory } from 'nextein/posts'

inCategory(category, options)

Filter function to be applied to posts to retrieve posts in a given category.

• category: {String} The category to filter results.
• options: {Object}
  • includeSubCategories: {Boolean} Set to true to include posts in sub categories. Default: false.

Using Categories

Categories are resolved by the folder structure by default. This means that a post located at posts/categoryA/subOne will have a category categoryA/subOne unless you specify the category name in frontmatter.

import { getPosts } from 'nextein/fetcher'
import { inCategory } from 'nextein/filters'
import Content from 'nextein/content'


export function getStaticProps () {
  return {
    props: {
      home: await getPostsFilterBy(inCategory('home'))
    }
  }
}
export default function Index ({ home })  { 
  return (
    <section>
    {
      home.map( (post, idx) => <Content key={post.__id} {...post} excerpt/> )
    }
    </section>
  )
})

If you want to retrieve all posts under a certain category, let's say categoryA which will include all those under subOne, use the options includeSubCategories: true. Or use a '/*' wildcard in the category name.

import { getPosts } from 'nextein/fetcher'
import { inCategory } from 'nextein/filters'
import Content from 'nextein/content'


export function getStaticProps () {
  return {
    props: {
      home: await getPostsFilterBy(inCategory('home', { includeSubCategories: true }))
      // this is the same as
      //await getPostsFilterBy(inCategory('home/*'))
    }
  }
}
export default function Index ({ home })  { 
  return (
    <section>
    {
      home.map( (post, idx) => <Content key={post.__id} {...post} excerpt/> )
    }
    </section>
  )
})
