How to Fix 'SyntaxError: Cannot use import statement outside a module' in Node.js?

Resolving "SyntaxError: Cannot use import statement outside a module" in Node.js

The error "SyntaxError: Cannot use import statement outside a module" occurs when using the ECMAScript (ES) module syntax in a non-module context. Here's how to resolve the issue:

Verify Node.js Version:

Ensure you have Node.js version 13.2.0 or higher installed. Earlier versions do not support ES module syntax natively.

Configure Module Types:

You have two options for configuring module types:

• Option 1: Package.json: Add a top-level "type": "module" field to the nearest parent package.json file. This instructs Node.js to treat all .js and .mjs files in that directory and its subdirectories as modules.

// package.json
{
  "type": "module"
}

• Option 2: File Extension: Explicitly name files that should be interpreted as modules using the .mjs extension. By default, .js files are interpreted as CommonJS modules.

Other Potential Issues:

• Babel Configuration: Check that your Babel configuration is correct. If you are using an outdated version or presets, it may not be compatible with ES module syntax.
• Plugins/Presets: Verify that your Babel plugins and presets are not exporting objects directly. They should be exported as functions instead.
