Display the latest WordPress articles, implemented using Vue

Question

I am rebuilding my WordPress blog using Vue. I'm trying to display my last 3 posts, I did it here:

<template>
    <section>
        <h4>Recent articles</h4>
        <div class="posts-recent">
            <div v-for="(post, index) in posts.slice(0, 3)" :key="post.id" class="post">
                <div :key="index">
                    <nuxt-link :to="`/blog/${post.slug}`" class="post-image" :style="{ backgroundImage: 'url(' post.fimg_url ')' } "></nuxt-link>
                    <div class="post-text">
                    <nuxt-link :to="`/blog/${post.slug}`" class="post-title" v-html="post.title.rendered"></nuxt- link>
                    </div>
                </div>
              </div>
        </div>
    </section>
</template>

<script>
  import { mapState, mapActions } from 'vuex';
  
  export default {
    name: 'Recent',
    created() {
      this.getPosts();
    },
    props: {
      slug: String
    },
    computed: {
      ...mapState(['posts']),
    },
    methods: {
      ...mapActions(['getPosts']),
    }
  };
</script>

This code works fine, but I want to display 3 articles while excluding the current article if the current article is one of the 3 most recent articles.

Answer 1

If you have the following article array

[
  { id: 1, slug: 'abc', url: 'https://' },
  { id: 2, slug: 'def', url: 'https://' },
  { id: 3, slug: 'ghi', url: 'https://' },
]

You can use a method similar to this.array.filter(post => post.slug !== this.$route.params.slug) to filter.
If this.$route.params.slug is equal to def, it will only give posts with ids 1 and 3.
