Syntaxerror: Cannot use import statement outside a module

Get your prerequisites batting right

At times, a simple update or setting can be your savior. Here are a few for avoiding the prevalent import error:

Update your JS engine

Node.js version 13.2.0 or higher supports ES6 modules natively. If you're on an antiquated version, it might be the time machine you need.

File extensions are game-changers

Use .cjs and .mjs extensions for CommonJS and ES modules respectively. Node.js recognizes these like a boss.

Babel users, upgrade your arsenal

Ensure you're running Babel 7 or higher. Also, correctly set your presets to avoid any babel-ic confusion.

TypeScript configurations

For TypeScript jugglers, ensure that the target and module compiler options are set right in tsconfig.json. Trust me, your transpiler will thank you!

Understanding the .mjs and .cjs battlefield

File extensions aren't mere ornamental decors. They dictate Node.js how to interpret the files.

• .mjs files are treated as ES modules.
• .cjs files use the CommonJS syntax.

When to employ the right troops

• .mjs all the way when you're embracing the ES modules like a family tradition.
• Resorting to .cjs can be your solace, especially with legacy codebases or if you cannot part ways with the dynamic nature of CommonJS.

The quandary of Import and Require

ES6 modules marching with "import"

• Use import when working with ES6 modules. JavaScript promised to unlock its treasures here.

CommonJS modules cheering "require"

• CommonJS modules, your good old friends in traditional Node.js, expect you to use require(). They still feel the spark.

Migrating to Babel 7

Transitioning to Babel 7 requires careful consideration of new presets and dependencies. Don't trip during the Babelic migration.

Dynamic imports

Use dynamic import() to load modules on demand inside a CommonJS context. It's like calling superheroes only when supervillains strike.

TypeScript maestros

The adjustment of TypeScript "target" and "module" settings can resolve errors. Coding never felt so much like a piano symphony!
