Common Mistakes

Trying to run a JavaScript file with ts-node.

Using a non-TypeScript file extension.

ts-node runs TypeScript files, so the file must have a .ts extension. Using .js or other extensions will cause errors.

💡 Hint

Common Mistakes

Putting the option after the file name.

Using --help instead of --transpile-only.

Passing a wrong argument file.

The command runs app.ts with ts-node, uses --transpile-only to speed up compilation by skipping type checks, and passes data.json as an argument.
