How to get a list of all posts under a specific WordPress category?

[3zmx]

As per the title, I want to fetch all posts under a specific category, but I couldn't find the relevant method in the composables from the documentation. Could someone help me with this? Is there something like useWPPostsByCategory()?

thanks : )

Thanks for trying out the WPNuxt module!

You are right that the module doesn't provide this query by default, but it is very easy to add it.

All you have to do is add a graphql query in the extend/queries as explained here: https://wpnuxt.com/docs/composables/custom-queries

So in your case you could add this file: [srcDir]/extend/queries/PostsByCategory.gql
with this content:

#import "~/.queries/fragments/Post.fragment.gql"

query PostsByCategoryId($categoryId: Int!) {
  posts(where: {categoryId: $categoryId}) {
    nodes {
      ...Post
    }
  }
}

query PostsByCategoryName($categoryName: String!) {
  posts(where: {categoryName: $categoryName}) {
    nodes {
      ...Post
    }
  }
}

When you start nuxt 2 new composables will automatically be generated, and can be used like this:

useWPPostsByCategoryId:

const { data } = await useWPPostsByCategoryId({ categoryId: 1 })

useWPPostsByCategoryName:

const { data } = await useWPPostsByCategoryName({ categoryName: 'myCategory' })
