Cannot find module or type declarations for side-effect import of ‘./globals.css’ ts(2882) – Error Solution

Error Overview

The error message “Cannot find module or type declarations for side-effect import of ‘./globals.css’ ts(2882)” typically occurs in TypeScript projects when the TypeScript compiler cannot locate the module or type definitions for a specific CSS file. This can be particularly frustrating for developers working with frameworks like React or Next.js, where CSS modules or global styles are common.

This error indicates that TypeScript is unsure how to handle the import of the globals.css file, which might be due to the absence of type definitions or incorrect configurations within your project.

Common Causes

Understanding the common causes of this error can help in effectively addressing the issue. Here are some reasons why you might encounter the error message:

1. Missing Type Declaration Files: TypeScript requires type declaration files (.d.ts) to understand the types of imported modules. If these are missing for CSS files, you will face this error.
2. Improper TypeScript Configuration: If your tsconfig.json file is not set up to handle CSS imports, TypeScript will throw an error.
3. File Path Issues: The path to the globals.css file may be incorrect or the file may not exist in the specified directory.
4. Framework Compatibility: Some frameworks may require specific configurations to handle CSS imports properly.
5. Cache Issues: Sometimes, TypeScript or the development toolchain may cache previous configurations, leading to persistent errors.

Solution Methods

To resolve the error “Cannot find module or type declarations for side-effect import of ‘./globals.css’ ts(2882)”, you can follow these solution methods:

Method 1: Create a Type Declaration File

If you do not have a type declaration file for CSS, you can create one easily.

1. Create a new file named globals.d.ts in your project’s src folder or the same directory as your globals.css file.
2. Add the following code to the globals.d.ts file to declare the module:

typescript
declare module '*.css';

1. Save the file and restart your TypeScript server or development environment.

Method 2: Update tsconfig.json

Ensure that your TypeScript configuration is set to handle CSS imports correctly.

1. Open your tsconfig.json file.
2. Make sure that the allowSyntheticDefaultImports and esModuleInterop options are set to true. Your tsconfig.json might look like this:

“`json
