How to Fix SendInBlue Import Errors in Your NodeJS Application

If you've tried refactoring your NodeJS application to utilize ES6 import modules, you may have encountered an error when importing the SendInBlue SDK. This guide will help you navigate this issue by breaking down the problem and providing an effective solution.

Understanding the Problem

As developers transition from CommonJS modules to ES6 import/export syntax, incompatibility issues can arise, particularly with libraries that are still written in CommonJS. You may have faced an error like this:

This typically happens when the imported library does not support named exports, leading to confusion when trying to access its properties or methods.

Example of the Error

You might be using a code snippet similar to this:

However, this results in an error:

Why This Happens

The error occurs because sib-api-v3-sdk is a CommonJS module. Thus, it doesn’t support named exports directly. You may also notice the following line in the error message:

This suggests that the correct approach is to import the module as a whole, then destructure it to access its components.

The Solution

To resolve the import issue, use an alias to import the entire module, making it easier to access its properties. Here’s how:

Step 1: Update Your Import Statement

Change your import statement to:

Conclusion

Switching to ES6 import modules in your NodeJS application can be a significant improvement, but it’s not without its challenges. When dealing with libraries that are still in CommonJS format, such as SendInBlue, it’s essential to ensure you're importing them correctly to avoid common pitfalls like the TypeError discussed here.

By following these simple steps, you can easily resolve the issue and continue developing your application without interruptions. Happy coding!
