Nextjs basepath
Next.js and GitHub Pages, how the basePath and assetPrefix configuration options will fix your website
tl;dr: When hosting a Next.js project on GitHub Pages (without a custom domain name) your internal links won't work as your project will be hosted on a subpath (e.g. ). The configuration property will fix this. Combine it with which fixes the paths for images and CSS stylesheets.
Preface
Next.js 9.5 contains a few really good enhancements to the React.js framework. Included in it is the new configuration variable for the file.
What is it?
The configurator allows you to serve your website pages under a subpath with no complex configuration. For example, if you're hosting docs you might want them to be at rather than . In addition to this, Next.js will automatically prefix any components to the .
To use a custom all you need to do is add the following to your .
Once thats added, all your content will be available on without changing any of your 's to other pages. Neat.
Why is it awesome?
Usually you'll find a website available on it's root path () but some free hosting platforms allow you to host using their domain but on a path.
GitHub Pages is one such platform.

It turns out that hosting a next.js application in a subdirectory isn’t as easy as it should be. There are two major issues that I’ve manage into when doing this: (1) Handling links to local pages and (2) Handling links to static assets.
The right way to handle this is to position the basePath in the next.config.js file. This will cause the next.js router to prepend the basePath to all links:
Unfortunately, there’s still some work to perform, as this will only control the routing. For any links to pages, we need to replace the tag with the tag, which will correctly employ the basePath to the link:
The biggest issue, however, is static assets, where the base route isn’t applied (even to components such as the component). There are several cited options which I’ve seen online including (which is ignored in modern next.js), the method (which doesn’t serve in non-router components), and the approach (where you specify the basePath in the next.config.js file and then access it via , which doesn’t work on client-side components). Instead, The top thing that I’ve found is to use from :
This works in both client-side and server-side components, and it
How to Implement Base Path in Your Next.js Application
When developing a web application with Next.js, managing your application's routing efficiently can significantly enhance its structure and performance. One powerful feature of Next.js is its ability to set a custom base path.
This serves as a common prefix for all your pages within the app, making it easier to deploy your app to different environments or alongside other applications on the same domain.
What is a Base Path?
In Next.js, the base path refers to a prefix that you can add to all the routes in your application. By utilizing the 'config' option in the 'next.config.js' file, you can set the base path, for instance, to /blog, making all your application’s paths start with /blog, such as /blog/about, /blog/contact, etc.
This is particularly useful when you want to run multiple applications under the same domain or deploy to environments where your app resides at a sub-path of the domain.
Setting Up the Base Path
To set up a base path in Next.js, you need to modify the next.config.js file. Here's a simple example of how to do this:
In this configuration, basePath is se

Hello everyone!
I’m trying to deploy a nextjs (13.0.3) website that has the option to essentially claim it has to be hosted on a subfolder.
I’ve set up and file with my variable and then
I’ve already prefixed the assets from public (as they claim it has to be manual) with
So far so good in local in dev mode and after I build and call but when I deploy here on Netlify when I go to the subpage, like it gives me 404, both on page and assets in the network.
Any clue?
Thanks!

Hi, did you tell netlify where to build your site from? Can you share what you put in your build settings. Also this doc might help:
Last reviewed by Netlify Support - August, 2023 Netlify attempts to lookup a file based on several xor filters, and when all of these fail, we end up serving a 404 page. For example, a request made to /example/ would check /example/index.html, /example.html, /example/home.html and several other combinations (not necessarily in the same order) before hitting the 404. However, in case you were not expecting a 404 at a particular URL, you might be interested in finding out the reason and potentia…

Hey @SamO , than
assetPrefix
Attention: Deploying to Vercel automatically configures a global CDN for your Next.js project. You do not need to manually setup an Asset Prefix.
Good to know: Next.js 9.5+ added support for a customizable Base Path, which is better suited for hosting your application on a sub-path like . We do not suggest you use a custom Asset Prefix for this use case.
Set up a CDN
To set up a CDN, you can set up an asset prefix and configure your CDN's origin to resolve to the domain that Next.js is hosted on.
Open and add the config based on the phase:
Next. path ( folder). For example, with the above configuration, the following request for a JS chunk:
Would instead become:
The exact configuration for uploading your files to a given CDN will depend on your CDN of choice. The only folder you need to host on your CDN is the contents of , which should be uploaded as as the above URL request indicates. Do not upload the rest of your folder, as you should not expose your server code and other configuration to the public.
While covers requests to , it does not influence the following paths:
- Files in the public folder; if you want to serve those assets over a
