I'm looking for the right url to reference static assets, like images within Vue javascript.
For example, I'm creating a leaflet marker using a custom icon image, and I've tried several urls, but they all return a 404 (Not Found):
Main.vue:
var icon = L.icon({
iconUrl: './assets/img.png',
iconSize: [25, 25],
iconAnchor: [12, 12]
});
I've tried putting the images in the assets folder and the static folder with no luck. Do I have to tell vue to load those images somehow?
For anyone looking to refer images from template, You can refer images directly using '#'
Example:
<img src="#/assets/images/home.png"/>
In a Vue regular setup, /assets is not served.
The images become src="data:image/png;base64,iVBORw0K...YII=" strings, instead.
Using from within JavaScript: require()
To get the images from JS code, use require('../assets.myImage.png'). The path must be relative (see below).
So your code would be:
var icon = L.icon({
iconUrl: require('./assets/img.png'), // was iconUrl: './assets/img.png',
// iconUrl: require('#/assets/img.png'), // use # as alternative, depending on the path
// ...
});
Use relative path
For example, say you have the following folder structure:
- src
+- assets
- myImage.png
+- components
- MyComponent.vue
If you want to reference the image in MyComponent.vue, the path sould be ../assets/myImage.png
Here's a DEMO CODESANDBOX showing it in action.
A better solution would be
Adding some good practices and safity to #acdcjunior's answer, to use # instead of ./
In JavaScript
require("#/assets/images/user-img-placeholder.png")
In JSX Template
<img src="#/assets/images/user-img-placeholder.png"/>
using # points to the src directory.
using ~ points to the project root, which makes it easier to access the node_modules and other root level resources
In order for Webpack to return the correct asset paths, you need to use require('./relative/path/to/file.jpg'), which will get processed by file-loader and returns the resolved URL.
computed: {
iconUrl () {
return require('./assets/img.png')
// The path could be '../assets/img.png', etc., which depends on where your vue file is
}
}
See VueJS templates - Handling Static Assets
Right after oppening script tag just add import someImage from '../assets/someImage.png'
and use it for an icon url iconUrl: someImage
this finally worked for me, image passed as prop:
<img :src="require(`../../assets/${image}.svg`)">
What system are you using? Webpack? Vue-loader?
I'll only brainstorming here...
Because .png is not a JavaScript file, you will need to configure Webpack to use file-loader or url-loader to handle them. The project scaffolded with vue-cli has also configured this for you.
You can take a look at webpack.conf.js in order to see if it's well configured like
...
{
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('img/[name].[hash:7].[ext]')
}
},
...
/assets is for files that are handles by webpack during bundling - for that, they have to be referenced somewhere in your javascript code.
Other assets can be put in /static, the content of this folder will be copied to /dist later as-is.
I recommend you to try to change:
iconUrl: './assets/img.png'
to
iconUrl: './dist/img.png'
You can read the official documentation here: https://vue-loader.vuejs.org/en/configurations/asset-url.html
Hope it helps to you!
It works for me by using require syntax like this:
$('.eventSlick').slick({
dots: true,
slidesToShow: 3,
slidesToScroll: 1,
autoplay: false,
autoplaySpeed: 2000,
arrows: true,
draggable: false,
prevArrow: '<button type="button" data-role="none" class="slick-prev"><img src="' + require("#/assets/img/icon/Arrow_Left.svg")+'"></button>',
Having a default structure of folders generated by Vue CLI such as src/assets you can place your image there and refer this from HTML as follows <img src="../src/assets/img/logo.png"> as well (works automatically without any changes on deployment too).
I'm using typescript with vue, but this is how I went about it
<template><div><img :src="MyImage" /></div></template>
<script lang="ts">
import { Vue } from 'vue-property-decorator';
export default class MyPage extends Vue {
MyImage = "../assets/images/myImage.png";
}
</script>
You could define the assets path depending on your environment
const dev = process.env.NODE_ENV != 'production';
const url = 'https://your-site.com';
const assets = dev ? '' : url;
<template>
<img :src="`${assets}/logo.png`"/>
<p>path: {{assets}}</p>
</template>
<script>
export default {
data: () => ({
assets
})
}
</script>
Ideally this would be inside an utils js file, or as an extended app defineProperty, like:
const app = createApp(component);
app.config.globalProperties.$assets = assets;
app.mount(element);
and will be available as:
<template>
<img :src="`${$assets}/logo.png`"/>
<p>path: {{$assets}}</p>
</template>
<script>
export default {
mounted() {
console.log(this.$assets);
}
}
</script>
load them in created, mounted or where you need them
async created() {
try {
this.icon = (await import('#assets/images/img.png')).default;
} catch (e) {
// explicitly ignored
}
and then
<img :src=icon />
Inside code you can directly require image using.
const src = require("../../assets/images/xyz.png");
Or
In order to dynamically load image need this.
const image = new window.Image();
image.src = require("../../assets/images/xyz.png");
image.onload = () => {
// do something if needed
};
I have a Materialize.min.css link
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/css/materialize.min.css">
And i need to include this file only in one template of Vue, because it damages other files.
Is it possible to do?
Copy all of the content from this URL https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/css/materialize.min.css and create a new css file then past the copied contents on your project.
mounted() {
const plugin = document.getElementById("__ID_OF_YOUR_SELECTED_ELEMENT__");
plugin.setAttribute(
"href",
"__PATH_OF_YOUT_CSS__"
);
plugin.async = true;
document.head.appendChild(plugin);
}
will apply only the element you had selected
I have a Nuxt Content project, which fetches a number of content files like so:
/content/resources/item.yaml
---
item:
title: Hello World
pdf: sample.pdf
Which is pulled into the Vue component:
async asyncData({ $content }) {
const resources = await $content('resources').fetch()
return { resources }
},
Where should the PDF file go in the Nuxt folder structure? and how should it be referred to in the YAML file? I'm trying something like:
/content/resources
-- item.yaml
-- sample.pdf
and then in Vue: <a :href="item.pdf" ..., which always just results in https://url/sample.pdf, which does not load obviously. What is the obvious thing I am missing, as I can't find it anywhere in the Nuxt Content docs?
/content/resources
-- item.yaml
/assets/files
-- sample.pdf
and referencing /assets/files/sample.pdf also doesn't work.
The Nuxt Content docs describe using static assets for this.
Move sample.pdf to static/ in the root of your Nuxt project (e.g., in static/sample.pdf), and then use its static-relative path in your pdf YAML property:
pdf: /sample.pdf
I have 2 problems:
If I use the variable in src:
I will get this link in the web and not exactly:
http://localhost:3000/~/assets/product/image/bg.png
Similar to the first problem.
I want to use dynamic css file in head() method:
export default {
head () {
const style = this.$cookie.get('app_style')
return {
link: [
{ rel: 'stylesheet', href: ~/assets/${style}.css }
]
}
}
}
To load dynamic images in the asset folder you can use require to tell webpack which image to load like so. In your template you can do:
<img :src="require(`../assets/img/${folderType}/bg1.png`)" />
Note: assuming folderType is defined in your script section
You can extract the require statement into a computed property(would make your template cleaner). So like so:
export default {
// ...
data() {
return {
folderType: 'folderTypeGoesHere'
}
},
computed: {
imagePath () {
return require(`../assets/img/${this.folderType}/bg1.png`) // the module request
}
}
}
Then in your template just use:
<img :src="imagePath" />
For your second problem, you could resolve to not using the tilde ~ alias and just use a relative path as I did in the image path example above.
It depends on your Nuxt version and also the bundler.
In Nuxt2 address starts with ~\assets\ however in Nuxt3 it starts with \assets\ .
Consider some png images in assets directory and the name of one of them is in img variable which can be changed dynamically.
If you are using Nuxt2 and Webpack, you need to use require like the following.
<img :src="require(`~/assets/${img}.png`)">
If you are using Nuxt3 and Vite
<img :src="`/assets/${img}.png`"/>
I was trying to use to embed the svg picture but it does not show anything. I looked at some other threads and it was suggested to add type="image/svg+xml", however, it did not solve the issue. When I am trying to look at the DOM for some reason it seems to create an endless loop. I attached the picture
This is the compononent
<template>
<div class="logo">
<object type="image/svg+xml" data="logo.svg">
</object>
</div>
</template>
This is the app.vue
template>
<div id="app">
<Demo></Demo>
</div>
</template>
<script>
import Demo from './components/Demo.vue'
export default {
name: 'app',
components: {
Demo
}
}
</script>

This happen because vue-loader doesn’t recognize paths in just any attribute. By default just recognize these ones: https://vue-loader.vuejs.org/options.html#transformasseturls
So, there are 3 possible solutions
Note: If you are not using eslint as linter you could remove eslint comments
1: Bind the route to your image
First add the next variable to your data in the component
data() {
return {
// eslint-disable-next-line global-require
mySvg: require('../assets/logo.svg'),
};
},
Next modify your template
<object type="image/svg+xml" :data="mySvg">
2: Add vue-loader rule
If you don't want to have to bind every svg image, you could add a rule to vue-loader in order to say how to handle data attribute in a object
Go to your webpack config file, if you created the project using vue-cli 3.x you have to create a vue.config.js file in the root (same level that package.json)
// vue.config.js
module.exports = {
chainWebpack: (config) => {
config.module
.rule('vue')
.use('vue-loader')
.loader('vue-loader')
.tap((options) => {
// eslint-disable-next-line no-param-reassign
options.transformAssetUrls = {
object: 'data',
};
return options;
});
},
};
if you want to check that the config was added, execute vue inspect > webpack.config and expect see something like this (inside webpack.config):
{
loader: 'vue-loader',
options: {
...
transformAssetUrls: {
object: 'data'
}
}
}
More info: https://cli.vuejs.org/guide/webpack.html#working-with-webpack
3: Replace default loader and use svg as vue components
Other option is use vue-svg-loader. This loader inlines the SVGs which enables you to modify them using css. Also optimize your files with SVGO
See more: https://vue-svg-loader.js.org/#vue-cli
It is worth checking that you don't have a CSS rule hiding object tags. Otherwise it seems correct. You probably need to check the path and make sure you can reach your image. I assume your filename is a dummy, but try to use an absolute path. And make sure you can hit the path and see the image in your browser.
