Assets directory
The assets
directory contains your un-compiled assets such as Stylus or Sass files, images, or fonts.
Images
Inside your vue
templates, if you need to link to your assets
directory use ~/assets/your_image.png
with a slash before assets.
<template>
<img src="~/assets/your_image.png" />
</template>
Inside your css
files, if you need to reference your assets
directory, use ~assets/your_image.png
(without a slash)
background: url('~assets/banner.svg');
When working with dynamic images you will need to use require
<img :src="require(`~/assets/img/${image}.jpg`)" />

Styles
Nuxt lets you define the CSS files/modules/libraries you want to set globally (included in every page). In the nuxt.config you can easily add your styles using the CSS Property.
nuxt.config.js
export default {
css: [
// Load a Node.js module directly (here it's a Sass file)
'bulma',
// CSS file in the project
'~/assets/css/main.css',
// SCSS file in the project
'~/assets/css/main.scss'
]
}
Sass
In case you want to use sass
make sure that you have installed sass
and sass-loader
packages.
Yarn
yarn add --dev sass sass-loader@10
NPM
npm install --save-dev sass sass-loader@10
Nuxt will automatically guess the file type by its extension and use the appropriate pre-processor loader for webpack. You will still need to install the required loader if you need to use them.
Fonts
You can use local fonts by adding them to your assets folder. Once they have been added you can then access them through your css using the @font-face.
-| assets
----| fonts
------| DMSans-Regular.ttf
------| DMSans-Bold.ttf
assets/main.css
@font-face {
font-family: 'DM Sans';
font-style: normal;
font-weight: 400;
font-display: swap;
src: url('~assets/fonts/DMSans-Regular.ttf') format('truetype');
}
@font-face {
font-family: 'DM Sans';
font-style: normal;
font-weight: 700;
font-display: swap;
src: url('~assets/fonts/DMSans-Bold.ttf') format('truetype');
}
CSS files are not automatically loaded. Add them using the CSS config property.

Webpack Assets
By default, Nuxt uses webpack’s vue-loader, file-loader and url-loader to serve your assets. You can also use the static directory for assets that should not run through webpack
Webpack
vue-loader automatically processes your style and template files with css-loader
and the Vue template compiler out of the box. In this compilation process, all asset URLs such as <img src="...">
, background: url(...)
and CSS @import
are resolved as module dependencies.
For example, we have this file tree:
-| assets/
----| image.png
-| pages/
----| index.vue
If you use url('~assets/image.png')
in your CSS, it will be translated into require('~/assets/image.png')
.
The ~/
alias won’t be resolved correctly in your CSS files. You must use ~assets
(without a slash) in url
CSS references, i.e. background: url("~assets/banner.svg")
If you reference that image in your pages/index.vue
:
pages/index.vue
<template>
<img src="~/assets/image.png" />
</template>
It will be compiled into:
createElement('img', { attrs: { src: require('~/assets/image.png') } })
Because .png
is not a JavaScript file, Nuxt configures webpack to use file-loader and url-loader to handle them for you.
The benefits of these loaders are:
file-loader
lets you designate where to copy and place the asset file, and how to name it using version hashes for better caching. In production, you will benefit from long-term caching by default!
url-loader
allows you to conditionally inline files as base64 data URLs if they are smaller than a given threshold. This can reduce the number of HTTP requests for trivial files. If a file is larger than the threshold, it automatically falls back to file-loader.
For these two loaders, the default configuration is:
// https://github.com/nuxt/nuxt.js/blob/dev/packages/webpack/src/config/base.js#L382-L411
{
test: /\.(png|jpe?g|gif|svg|webp|avif)$/i,
use: [{
loader: 'url-loader',
options: {
esModule: false,
limit: 1000, // 1kB
name: 'img/[name].[contenthash:7].[ext]'
}
}]
},
{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/i,
use: [{
loader: 'url-loader',
options: {
esModule: false,
limit: 1000, // 1kB
name: 'fonts/[name].[contenthash:7].[ext]'
}
}]
},
{
test: /\.(webm|mp4|ogv)$/i,
use: [{
loader: 'file-loader',
options: {
esModule: false,
name: 'videos/[name].[contenthash:7].[ext]'
}
}]
}
Which means that every file below 1 kB will be inlined as base64 data URL. Otherwise, the image/font will be copied in its corresponding folder (inside the .nuxt
directory) with a name containing a version hash for better caching.
When launching your application with nuxt
, your template in pages/index.vue
:
pages/index.vue
<template>
<img src="~/assets/your_image.png" />
</template>
Will be transformed into:
<img src="/_nuxt/img/your_image.0c61159.png" />
If you want to change the loader configurations, please use build.extend.
Aliases
By default the source directory (srcDir) and the root directory (rootDir) are the same. You can use the alias of ~
for the source directory. Instead of writing relative paths like ../assets/your_image.png
you can use ~/assets/your_image.png
.
Both will achieve the same results.
components/Avatar.vue
<template>
<div>
<img src="../assets/your_image.png" />
<img src="~/assets/your_image.png" />
</div>
</template>
We recommend using the ~
as an alias. @
is still supported but will not work in all cases such as with background images in your css.
You can use the alias of ~~
or @@
for the root directory.
Tip: On Spanish keyboard you can access ~
with (Option
+ ñ
) on Mac OS, or (Alt gr
+ 4
) on Windows
