Dynamic CSS background images with Nuxt.js: a guide

Currently working with Nuxt.js and have developed a unique custom component.

The component contains CSS that applies a background image using styling.

However, the code I've implemented is resulting in an error message when attempting to run it. The specific error reads:

 invalid expression: Invalid regular expression flags in

Here is the Component Code:

<template>
  <section class="bg-img hero is-mobile header-image" v-bind:style="{ backgroundImage: 'url(' + image + ')' }">
    <div>
      <div class="hero-body">
        <div class="container">
          <h1 class="title">
            {{ result }}
          </h1>
          <h2 class="subtitle">
            Hero subtitle
          </h2>
        </div>
      </div>
    </div>

</section>
</template>

<script>

export default {
  props: ['result', 'image']
}
</script>


<style>



.bg-img {
        background-image: url(~/assets/autumn-tree.jpg);
        background-position: center center;
        background-repeat: no-repeat;
        background-attachment: fixed;
        background-size: cover;
        background-color: #999;

 }

</style>

Answer №1

I stumbled upon the solution at https://github.com/nuxt/nuxt.js/issues/2123.

Essentially, within the component, you can achieve this by:

<div :style="{ backgroundImage: `url(${backgroundUrl})` }">Insert content with background here</div>

Answer №2

url('~@/assets/autumn-tree.jpg')

Initially, I incorrectly assumed that this was an issue with nuxtjs. In reality, webpack utilizes certain syntax to handle assets.

The tilde (~) signifies to webpack that the request should be treated as a module request, while the at symbol (@) indicates starting from the root directory.

This is a different example that showcases how to use both require and url together to locate an asset.

   <b-col cols="8" class="hj_projectImage justify-content-center text-center" :style="{backgroundImage: `url(` + require(`~/assets/ProjectPictures/${this.ProjectPicture}`) + `)`}">
  </b-col>

One approach is to keep it simple by enclosing it in single quotes: 'background-image'

v-bind:style="{ 'background-image': 'url(' + api.url + ')' }"

If you're looking for a great image solution, I highly recommend checking out nuxt-image

With nuxt-image, you have the ability to specify images based on resolution using media queries. Additionally, you can use the $img-feature to set images as background-images:

export default {
  computed: {
    backgroundStyles() {
      const imgUrl = this.$img('https://github.com/nuxt.png', { width: 100 })
      return {
        backgroundImage: `url('${imgUrl}')`
      }
    }
  }
}

Having trouble with 'require' in my Nuxt3 project using Vite, resulting in a frustrating 500 error stating 'require not defined'.

To resolve this issue, I found a workaround by utilizing 'import' in the parent component and passing it down as a prop:

Parent Component:

<template>
  <div class="flex flex-col h-screen">
    <NavHeader />
    <HeroPage
      :pageImage="pageImage"
    />
    <NavFooter />
  </div>
</template>

<script>
//Import the banner image.
import pageImage from "~/assets/banner/page-banner-about-us.jpg";

export default {
  data() {
    return {
      pageImage: pageImage
    };
  },
};
</script>

Child Component:

<template>
  <div
    class="mx-auto relative block w-[1200px] top-0 z-10 overflow-hidden mt-0 mb-0 bg-cover py-16 rounded-b-lg"
    :style="bgImage"
  >
  </div>
</template>

<script>
export default {
  props: {
    pageImage: {
      type: String,
      default: "",
    },
  },

  data() {
    return {
      bgImage: {
        "background-size": "cover",
        "background-image": `url(${this.pageImage})`,
      },
    };
  },
};
</script>

If you're looking for a solution, the official documentation has it covered: https://nuxtjs.org/docs/2.x/directory-structure/assets#images

One simple step is all that's needed - just eliminate the slash:

background-image: url("~assets/autumn-tree.jpg");

For more dynamic imagery, such as ${image}.jpg:

<img :src="require(`~/assets/img/${image}.jpg`)" />
