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.$assets);
}
}
</script>
load them in created, mounted or where you need them
async created() {
try {
this.icon = (await import('#assets/images/img.png')).default;
} catch (e) {
// explicitly ignored
}
and then
<img :src=icon />
Inside code you can directly require image using.
const src = require("../../assets/images/xyz.png");
Or
In order to dynamically load image need this.
const image = new window.Image();
image.src = require("../../assets/images/xyz.png");
image.onload = () => {
// do something if needed
};
I have 2 problems:
If I use the variable in src:
I will get this link in the web and not exactly:
http://localhost:3000/~/assets/product/image/bg.png
Similar to the first problem.
I want to use dynamic css file in head() method:
export default {
head () {
const style = this.$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`"/>
For a software development marketing site, I have more than 30 landing pages which I like to keep them in ./pages/landing folder. So, obviously the files inside ./pages/landing can be accessed by, for eg:
www.lorem.com/landing/python-development-experts/
www.lorem.com/landing/java-development-experts/
but I need to eliminate /landing/ from the path and still like to keep the files inside ./pages/landing folder, but need access the files using this paths:
www.lorem.com/python-development-experts/
www.lorem.com/java-development-experts/
Please help, thanks.
Here is what I did in nuxt.config.js
router: {
extendRoutes: (routesIn) => {
routesIn.forEach((r) => {
if (r.path.includes('/landing/')) {
r.path = r.path.replace('/landing', '');
}
});
return routesIn;
},
},
you can extend your route checkout this link

Maybe its help !
Thanks !
My project structure is as follows:
src
..lib
....someLibrary.js
bundles.js:
"bundles": {
"dist/app-build": {
"includes": [
"[**/*.js]",
"**/*.html!text",
"**/*.css!text"
],
"options": {
"sourceMaps": 'inline'
"inject": true,
"minify": true,
"depCache": true,
"rev": true
}
},
The project builds fine, but when I check app-build.js I don't find a definition for lib/someLibrary.js. I am using typescript for my own project so I assume this has something to do with that, how can I mix regular js files and output from my transpiled TS files into the same app-build bundle?
Update
So I tried to split the 'build-system' gulp task into two tasks: 'build-typescript' which is the same as 'build-system' was before, then I created 'build-libs' which looks like so:
gulp.task('build-libs', function() {
return gulp.src(paths.root + '**/*.js')
.pipe(plumber({errorHandler: notify.onError('Error: <%= error.message %>')}))
.pipe(changed(paths.output, {extension: '.js'}))
.pipe(sourcemaps.write('.', { includeContent: false, sourceRoot: '/src' }).on('error', gutil.log))
.pipe(gulp.dest(paths.output));
});
I then added to my dist/app-build bundle config: "lib/someLibrary.min.js"
And now my app-build.js does have the library defined, however when I try to use the library in one of my views using:
<require from="lib/someLibrary.min.js">
I get an error:
Failed to load resource: the server responded with a status of 404 (Static File '/dist/lib/someLibrary.min.html' not found)
What?!?? Why is it looking for html when nowhere is html ever involved in this whole scenario? Why is something that should be easy this hard?
Update2
So apparently 'require' does not work with javascript files. I changed to use the 'script' tag, however it seems these get stripped out when rendered by Aurelia. I am at a loss as to how to get Aurelia to do what I want it to.
Ok so after much frustration and disbelief at how hard something so simple could be, in addition to the changes to the build tasks mentioned above (which includes the javascript library file that has no npm/jspm package into the app-bundle) I created a modified version of this solution which looks as follows:
import { bindable, bindingMode, customElement, noView } from 'aurelia-framework';
#noView()
#customElement('scriptinjector')
export class ScriptInjector {
#bindable public url;
#bindable public isLocal;
#bindable public isAsync;
#bindable({ defaultBindingMode: bindingMode.oneWay }) protected scripttag;
public attached() {
if (this.url) {
this.scripttag = document.createElement('script');
if (this.isAsync) {
this.scripttag.async = true;
}
if (this.isLocal) {
const code = 'System.import(\'' + this.url + '\').then(null, console.error.bind(console));';
this.scripttag.text = code;
} else {
this.scripttag.setAttribute('src', this.url);
}
document.body.appendChild(this.scripttag);
}
}
public detached() {
if (this.scripttag) {
this.scripttag.remove();
}
}
}
To use it, simply add the following tag to the view where you want the script library to be used as follows:
<scriptinjector url="lib/bootstrap-toc.js" is-local.bind='true'></scriptinjector>
This will keep the original scriptinjector functionality which allows you to add remote 3rd party libraries to your Aurelia app but it will also allow you to load any local 3rd party libraries that you have bundled with your app.
Hope this helps someone.
I want to include my custom js file which is in C:\xampp\htdocs\yii2\vendor\bower\backend\assets\js but console gives me error
Failed to load resource: the server responded with a status of 404 (Not Found)
While other same file have same above directory which is working.
In my appAsset file is under C:\xampp\htdocs\yii2\backend\assets
<?php
namespace backend\assets;
use yii\web\AssetBundle;
/**
* Main backend application asset bundle.
*/
class AppAsset extends AssetBundle
{
//public $basePath = '#webroot';
//public $baseUrl = '#web';
public $sourcePath = '#bower/backend/';
public $css = [

'assets/css/style.css',
'assets/css/font-awesome.min.css',
'assets/css/bootstrap.min.css',

}
and my-custom.js
<script>
$(document).ready(function(){
$('li.active .treeview').on('click', function(e) {
$('li.active .treeview-menu').toggleClass("hide");
e.preventDefault();
});
});
</script>
The url of the file which is not finding is this
http://localhost/yii2/backend/web/assets/c4875c89/assets/js/my-custom.js
Simply add this in view file
<?php
$this->registerJsFile('PATH_TO_FILE');
?>
Use RegisterJsFile concept:
You should simply register this js file in your view, e.g. :
$this->registerJsFile('#web/js/specific.js');
Or your custompath
$this->registerJsFile('PATH_TO_FILELOCATION');
