Next image unconfigured host
Component development with ladle and next/image
Sometimes it is easier to build a component in isolation than in the place where it will be used. It is much easier to test all variations and edge cases of the component. There are tools out there which can help us to build our components in isolation. The most famous is Storybook, but I like to use Ladle. Ladle is much smaller than Storybook and it is built for speed. In this post we will set up Ladle and we will learn how we can use next/image within Ladle.
Setup
First we have to install Ladle:
And for most installations, that's it. Ladle has a useful default configuration, you only need to create a configuration if your installation differs from the default. But for most Next.js installations the default does not fit. Ladle expects stories and components in the "src" folder, but in many Next.js installations they are in a folder called components. So we have to create a configuration at :
With this configuration ladle is able to find our stories. A good time to write our first story.
First Story
We want to create our first Story for the following component.
components/Avatar.tsx
We want to create a s
Next-image-unconfigured-host image error.
One of your pages that leverages the component, passed a value that uses a hostname in the URL that isn’t defined in the in .
By simple words, it happens, when you are trying to pass into the image src external image link instead of local. Because the external image src is very handy method of displaying images, I want to deal with you with one of the solutions of this error.
Go to your next.config.js file and you willl see this code
const nextConfig = {
reactStrictMode: true,
}
Change it to this:
const nextConfig = {
images: {
domains: [
“img.freepik.com”,
“images.pexels.com”
],
},
}
In my case I was using image external paths from freepik.com and pexels.com, that’s why I have added those domains to my next.config.js, in order to say, that I import images from these urls.
I hope this solution will aide you.

Configuring next.config.js to implement Image tag
Hi All, I have two queries on next.config.js.
I am currently using Nextjs for my frontend and Strapi CMS for my backend.
Currently, my Strapi is deployed on DigitalOcean and I have created a Space to store images instead of using a database. Link as follows: https://next-cms-strapi-spaces.sgp1.digitaloceanspaces.com
My main Strapi backend is deployed on DigitalOcean and link is as follows:
https://nextjs-strapi-cms-45gnt.ondigitalocean.app
My front end is deployed on Vercel. I am still trying to figure things on using Nextjs framework and currently would like to use Image instead of img tag, therefore the next.config.js is as follows:
Qns 1:
I am currently still working on localhost and somehow when I implement the code above into next.config.js; it throws this error. I don’t seem to have a .next/trace in the folder after running . Is there a way to fix this error?
Error msg:
Qns 2. One of the image url link is as follows: https://next-cms-strapi-spaces.sgp1.digitaloceanspaces.com/aa7f294677adda00fa96235a76426c01.jpg, therefore is there a way to make the pathname dynamic? I tried using , would like to know whether is
Hostname is not configured under images in your next.config.js
This error means the hostname you're trying to use for image loading in Next.js is not configured in the file.
When using Next.js's component from the package, it is necessary to specify any external domains you want to load images from in your file. The reason is explained below.
Here's an example of how you can add hostnames to your Next.js configuration:
In the above configuration, and are the hostnames from which I plan to load images. You need to replace them with the domains you use in your project.
Then I can load the image like the one below:
Why do I have to configure the domain in next.config.js?
When using the component in Next.js, I need to specify external domains in the file for a couple of reasons:
- Security: By specifying a list of allowed domains, you prevent potential security risks of loading images from random URLs. That could include, for example, loading an image that carries malicious code or from an insecure source.
- Optimization: The component provides several benefits, such as automatic resizing, optimizing images for different devices, and lazy loading. When you spec
Three ways to handle responsive images in App Router
To apply responsive images, additional styling with or along with the property is required.
In , there are three ways to do this, as shown below.
Dynamic sources must have the and properties set. Otherwise, an error is returned.
If you want to ratio them, you can adjust them with and .
If the source image has a ratio of 3:2, you can see the following result with devtool if you set the values of and .
Note that width and height are overridden by the value of the style property.
Also, if you're fetching the URL of an external image, you'll need to allow that host in . If you don't, you may get an error like the one below.
next.config.js ](nextjs.org/docs/messages/next-image-unconfi..)
Here's how to allow it
Values except are optional.
See Configuration Options for more information.
If you don't know the ratio, create a wrapper around the image with the property and set the wrapper ratio via position: relative in that wrapper.
The property allows you to stretch or crop the image.
