When using the Vite build tool as a developer, you could see the problem "manifest not found at: public/build/manifest.json" When Vite is unable to find the manifest.json file during the build process, this error happens. We will look at the reasons of this problem and offer fixes in this article.
What is Vite?
A build tool for contemporary web applications is Vite. It is made to be quick, simple to use, and incredibly adaptable. React, Vue, and Angular are just a few of the front-end frameworks and packages that Vite supports.
Understanding the Manifest File
The Vite build process relies heavily on the manifest file. It includes information about the build-generated assets, including CSS and JavaScript files. The server converts these assets' URLs to the locations of their real files using the manifest file.

Causes of the Manifest Not Found Error
There are a number of causes for the manifest not found problem. Here are a few typical reasons:
The wrong file path
If the manifest file's file path is incorrect, the error may happen. The manifest.json file must be in the public/build directory in order for Vite to recognize it. Vite won't be able to find the file if it is in a different location or has a different name.
Corrupted Manifest File
Vite might not be able to read the manifest file if it is malformed or includes false information. The manifest not found error may result from this.
Missing Dependencies
To build and operate your application, Vite requires a number of packages. Vite may be unable to find the manifest file if any of these dependencies are either old or missing.
Solutions to Fix the Manifest Not Found Error
Here are some solutions to fix the manifest not found error:
Check File Path
Verify that the manifest file is in the appropriate directory as the first step. Make sure the file has the right name and is in the public/build directory. (manifest.json). You can relocate the file to the appropriate directory if it's in the wrong place.
Check Manifest File
Verify the manifest file's contents to see if the file path is right. Verify that the file contains valid data and is not corrupted. To verify the file's validity, utilise a JSON validator.
Update Dependencies
Ensure that all of Vite's necessary dependencies are installed and current. The following command can be used to check for out-of-date dependencies:
npm outdated
If any dependencies are outdated, you can update them using the following command:
npm update
Restart Vite
Sometimes the manifest not found error can be resolved by simply restarting Vite. By typing CTRL + C on the terminal, you can halt Vite and resume it with the following command:
npm run dev
Clear Cache
If the above solutions do not work, you can try clearing the cache of Vite. To clear the cache, run the following command:
npm run clear
Upgrade Vite
The manifest not found problem may appear if you are using an old version of Vite. This problem can be resolved by updating Vite to the most recent version. By executing the following command, Vite can be upgraded:
npm install vite@latest
