I want to show a background image from my assets folder. When I use an image tag, the image is shown properly, so the image is well placed, but throws a 404 when I use the background-image style. Any idea about what is happening?. I am using Vue 3 with TypeScript and Vite 2.
This does not resolve the URL:
<div style="background-image: url(./assets/img/header.png)"
></div>
But this does:
<img src="./assets/img/header.png" alt="Header" />
The URL needs to be resolved with import in <script>. @vue/compiler-sfc does not automatically resolve the URLs in <div>.style, but it does for <img>.src, which is why your second example works correctly.
Use the import keyword in a <script> block to expose the resolved image URL to the template:
<script setup>
import imagePath from '@/assets/logo.svg'
</script>
<template>
<div class="logo" :style="{ backgroundImage: `url(${imagePath})` }"></div>
</template>
<style>
.logo {
height: 400px;
width: 400px;
}
</style>
This is due to vite can't handle alias by default, so we need to set up an alias in vite config file.
there is no need to setup the import image in script tag.
just put the below code in vite.config.js file
import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";
import path from "path";
export default defineConfig({
plugins: [vue()],
resolve: {
alias: {
"@": path.resolve(__dirname, "/src"),
"~@": path.resolve(__dirname, "/src"),
},
},
});
