Introduction

As a developer working on an Angular project, you may encounter various errors while using third-party libraries. One such error is the "Cannot find module" error, which can be frustrating to resolve. In this article, we will discuss a specific error related to the @microblink/blinkid-in-browser-sdk library and provide a solution using patch-package.

The Error

The error occurs when trying to import the getAdditionalProcessingInfo function from the sdk.service.d.ts file in the @microblink/blinkid-in-browser-sdk/ui/dist/types/utils directory. The error message is as follows:

Error: node_modules/@microblink/blinkid-in-browser-sdk/ui/dist/types/utils/sdk.service.d.ts:15:95 - error TS2307: Cannot find module '../../../types/Recognizers/BlinkID/Generic/AdditionalProcessingInfo' or its corresponding type declarations.

export declare function getAdditionalProcessingInfo(result: BlinkIDSDK.BlinkIDResult): import("../../../types/Recognizers/BlinkID/Generic/AdditionalProcessingInfo").AdditionalProcessingInfo;

The Issue

The issue is that the import statement is missing one folder level. The correct import statement should be ../../../../types/Recognizers/BlinkID/Generic/AdditionalProcessingInfo instead of ../../../types/Recognizers/BlinkID/Generic/AdditionalProcessingInfo.

The Solution

To resolve this issue, you can use patch-package to patch the @microblink/blinkid-in-browser-sdk library. patch-package is a tool that allows you to patch third-party libraries without modifying the original code.

Here is the diff that solved the problem:

diff --git a/node_modules/@microblink/blinkid-in-browser-sdk/ui/dist/types/utils/sdk.service.d.ts b/node_modules/@microblink/blinkid-in-browser-sdk/ui/dist/types/utils/sdk.service.d.ts

Introduction

In our previous article, we discussed a specific error related to the @microblink/blinkid-in-browser-sdk library and provided a solution using patch-package. In this article, we will answer some frequently asked questions (FAQs) related to this error and provide additional information to help you resolve similar issues.

Q: What is the "Cannot find module" error?

A: The "Cannot find module" error occurs when the TypeScript compiler (tsc) cannot find the module or type declaration that is being imported. This error is usually caused by a mismatch between the import statement and the actual location of the module or type declaration.

Q: Why is the import statement incorrect?

A: The import statement is incorrect because it is missing one folder level. The correct import statement should be ../../../../types/Recognizers/BlinkID/Generic/AdditionalProcessingInfo instead of ../../../types/Recognizers/BlinkID/Generic/AdditionalProcessingInfo.

Q: How do I resolve the "Cannot find module" error?

A: To resolve the "Cannot find module" error, you can use patch-package to patch the @microblink/blinkid-in-browser-sdk library. patch-package is a tool that allows you to patch third-party libraries without modifying the original code.

Q: What is patch-package?

A: patch-package is a tool that allows you to patch third-party libraries without modifying the original code. It is a simple and efficient way to resolve issues with third-party libraries.

Q: How do I use patch-package?

A: To use patch-package, you need to install it as a dev dependency in your project. Then, you can create a patch file that contains the necessary changes to resolve the issue. Finally, you can apply the patch file to the @microblink/blinkid-in-browser-sdk library using the patch-package command.

Q: What are some common issues that can cause the "Cannot find module" error?

A: Some common issues that can cause the "Cannot find module" error include:

  • Mismatch between the import statement and the actual location of the module or type declaration
  • Incorrect use of relative paths in the import statement
  • Missing or incorrect type declarations
  • Conflicting dependencies

Q: How can I prevent the "Cannot find module" error?

A: To prevent the "Cannot find module" error, you can follow these best practices:

  • Use absolute paths in the import statement
  • Verify that the module or type declaration exists and is correctly located
  • Use the --noEmit flag when compiling TypeScript code to prevent the compiler from emitting type declarations
  • Use a linter or code analyzer to detect and prevent common issues

Conclusion

In conclusion, the "Cannot find module" error can be frustrating to resolve, but using patch-package can make it easier. By following the best practices and using the correct tools, you can prevent and resolve similar issues in the future.
