Fixing 'Cannot Find Module' Error for Local Files in Node.js

The 'Cannot find module' error for local files in Node.js occurs when the runtime cannot locate a required file due to incorrect file paths or missing extensions.

This error is common when using require() or import statements to include modules in your application.

For example, requiring a file with an incorrect relative path like require('./module') instead of require('./module.js') can trigger this error.

To fix this issue, ensure that the file path provided in the require() or import statement is accurate and includes the correct file extension if required.

Use relative paths (./ or ../) for local modules and absolute paths for global modules.

If you frequently encounter this error, consider using a path aliasing solution, such as module-alias, to simplify module resolution.

Additionally, verify that the file exists in the expected location by checking your project directory structure.

For TypeScript projects, ensure that the compiled JavaScript files are present in the output directory and that the tsconfig.json file is correctly configured.

By verifying file paths, extensions, and directory structures, you can resolve 'Cannot find module' errors for local files and ensure smooth module loading in your Node.js application.
