I want to import a function in my js file. Here is a simple code:
// In index.js file
function addition(a, b) {
return a + b;
}
export { addition };
// In test.js file
import { addition } from "./index.js";
console.log(addition(5, 4));The result in the console:
Thanks !
NodeJS uses CommonJS Module syntax which doesn't support import/export, but instead requires to use module.exports like so:
// In index.js file
function addition(a, b) {
return a + b;
}
module.exports = addition;
// In test.js file
const addition = require("./index.js");
console.log(addition(5, 4));
package.json file. It's required for one of the two solutions in the error to work. It could be created if it doesn't already exist.To use the modern import/export syntax with NodeJS you have to set your package type to module in the package.json file, like you are told in the console output.
