If you’re trying to publish an npm package to CodeArtifact but keep running into errors, it might be due to certain size limits imposed by the platform. Specifically, CodeArtifact has a maximum request size of 2 GB, which covers both the package metadata and the content of the package itself.
One common issue is the size of the package.json file in your package. For example, if you’re working with a package like @mui/icons-material version 9.0.0, it may have a package.json file around 1.37 MB. This exceeds the 1 MB limit that CodeArtifact enforces on the metadata portion of the request.
It’s important to note that this metadata limit is separate from the maximum size allowed for the actual asset files in your package. While the asset size can sometimes be increased by requesting a quota increase, the metadata size limit and the overall 2 GB request size are fixed constraints that cannot be changed.
If you’re unable to reduce the size of the package.json file—for example, by removing unnecessary data or simplifying it—you won’t be able to publish this version directly to CodeArtifact.
To work around this, you might consider using an earlier version of the package that has a smaller package.json file, or reach out to the package maintainers—like the MUI team—to see if they can help reorganize their package’s metadata.
Remember, understanding these limitations can save you time and help you find the best way to manage your package publishing process.
