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 withPosts, { inCategory } from 'nextein/posts'

export default withPosts( ({ posts }) => { 
  const homePosts = posts.filter(inCategory('home'))
  /* render your homePosts here */ 
})

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.

import withPosts, { inCategory } from 'nextein/posts'

export default withPosts( ({ posts }) => { 
  const categoryAPosts = posts
    .filter(inCategory('categoryA', { includeSubCategories: true }))
  /* render your categoryAPostsmePosts here */ 
})
