Understanding the Uncaught TypeError: Failed to resolve module specifier "firebase" Error

If you have recently updated your JavaScript code to include Firebase’s modular SDK (version 9 and above), you may encounter an error that halts your development process. The error message reads: "Uncaught TypeError: Failed to resolve module specifier 'firebase'. Relative references must start with either '/', './', or '../'." This can be quite frustrating, especially if you have already integrated necessary packages.

In this guide, we’ll walk through what this error means, why it occurs, and how to effectively resolve it so you can continue building your application with Firebase without a hitch.

What is the Cause of the Error?

This error typically surfaces when the JavaScript import statement cannot resolve the specified module. Here are the primary reasons that lead to this issue:

Incorrect Import Syntax: The error is likely occurring because the import statement is looking for a local module instead of an external library which usually requires a URL reference in modular imports.

Improper Module Structure: Unlike previous versions of Firebase, version 9 is fully modular. Assuming that the core Firebase functionality is accessible locally when it's actually not can lead to this issue.

How to Fix the Error

Fortunately, the fix for this problem is straightforward. Follow these below-mentioned steps to properly import Firebase modules in version 9.

Step 1: Update Your Import Statements

Instead of relying on the import of 'firebase', use the specific URLs that point directly to Firebase’s hosted libraries. Here’s how you can adjust your import statements:
