Introduction

In the world of software development, managing dependencies and ensuring compatibility is crucial for a smooth and efficient development process. However, sometimes, even with the best intentions, mistakes can occur, leading to issues that can be challenging to resolve. One such issue is when the types field in a package.json file does not match the actual library filename. This problem can lead to lint errors, making it difficult to maintain and update codebases.

Describe the Bug

Since version 5.1.2, the package.json file has been updated to include types as dist/index.d.ts. However, this file no longer exists, and the actual library filename is now dist/index.d.mts. This change was introduced in a commit related to bundling changes, which no longer outputs index.d.ts.

Impact on Development

The impact of this issue is significant, especially when using tools like eslint-plugin-import-x. This plugin is designed to help developers catch import-related errors, but when the types field in the package.json file does not match the actual library filename, it can lead to lint errors. In the case of @stepperize/react, the error message is:

error  Unable to resolve path to module '@stepperize/react'  import-x/no-unresolved

Understanding the Issue

To understand the issue, let's take a closer look at the package.json file. The types field is used to specify the location of the type definitions for a library. In this case, the types field is set to dist/index.d.ts, which is no longer the correct location of the type definitions.

The Commit that Introduced the Change

The commit that introduced the change is a0029f70f2f85a2f39bd9674e939114ef604479b. This commit was related to bundling changes, which no longer outputs index.d.ts.

The Impact on npm Packages

This issue affects all packages, not just @stepperize/react. The types field in the package.json file needs to be updated to match the actual library filename.

Solution

To resolve this issue, the types field in the package.json file needs to be updated to match the actual library filename. In this case, the types field should be set to dist/index.d.mts.

Conclusion

In conclusion, the issue of the types field in the package.json file not matching the actual library filename is a significant problem that can lead to lint errors. The solution is to update the types field to match the actual library filename. This will ensure that the development process is smooth and efficient, and that the codebase is maintained and updated correctly.

Recommendations

To avoid this issue in the future, it's essential to:

Regularly review the package.json file to ensure that the types field matches the actual library filename.
Use tools like eslint-plugin-import-x to catch import-related errors.
Keep the package.json file up-to-date with the latest changes.
