Component that dynamically changes background images in Vue

I'm currently working on a Vue banner that requires a dynamic background, but for some reason, it's not functioning as expected. I've experimented with different methods, and using an image tag like this works:

<img :src="require(`@/assets/images/${backgroundImage}`)" />

However, I need this to be an inline background image.

Here's the code:

Component

<template>
  <div
    class="w-full h-64 bg-auto bg-no-repeat bg-center lg:bg-cover relative"
    :style="{ backgroundImage: url(require('@/assets/images/' + backgroundImage))}"
  >
    <div class="w-full h-full flex flex-col justify-center items-center text-white px-6">
      <div class="hero-text rounded text-center py-8 px-12">
        <p class="text-base lg:text-md uppercase font-medium">{{ smallLeadingText }}</p>
        <h1 class="text-xl md:text-3xl lg:text-5xl uppercase font-bold">{{ mainText }}</h1>
        <p class="text-base lg:text-md">{{ subText }}</p>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  name: "PageHero",
  props: {
    backgroundImage: String,
    smallLeadingText: {
      type: String,
      required: false
    },
    mainText: {
      type: String,
      required: true
    },
    subText: {
      type: String,
      required: false
    }
  }
};
</script>

View

<PageHero
  backgroundImage="mc-background.png "
  smallLeadingText="Powerful, secure &amp; affordable"
  mainText="Minecraft hosting"
  subText="Plans suitable for all budgets"
/>

Answer №1

It appears that there are syntax errors in the style attribute related to string quoting. Why not give this a try:

<div :style="{ backgroundImage: `url(${require('@/assets/images/' + backgroundImage)})` }">

Alternatively, you could simplify things by creating computed properties to handle everything

computed: {
  bgImage () {
    return require('@/assets/images/' + this.backgroundImage)
  },
  inlineStyle () {
    return {
      backgroundImage: `url(${this.bgImage})` 
    }
  }
}

Implement it like so:

<div :style="inlineStyle">

Point 1: Coding Style

While the previous solution did not work for my specific case, the following code snippet successfully accomplishes the task:

<div :style="{ backgroundImage: `url(${'src/assets/images/' + backgroundImage})`}"></div>

It is important to note that the height property must be implemented in order to display the image correctly.

By utilizing this solution, the need for the "require" statement is eliminated, preventing the common error of "require" being undefined.

Point 2: File Path

To troubleshoot potential issues with loading the image, it is suggested to inspect the browser's console in the Network tab to verify if the image is being successfully loaded. Incorrect paths can impede the image loading process, as seen in examples such as:

'../assets/images/'

and

'@/assets/images/'

Despite these paths not working in my scenario, the following paths proved to be effective:

'src/assets/images'

and

src/images

These alternatives yielded successful results depending on the project structure. The discrepancy in including the 'assets' directory in some projects but not in others remains unexplored. As a workaround for now, trying these different path options may resolve the issue.
