[Solved] SyntaxError: Cannot use import statement outside a module

SyntaxError: Cannot use import statement outside a module


Problem: When debugging js code with vs code, I get “SyntaxError: Cannot use import statement outside a module”

import express from "express";

const app=express();
app.listen(9527,function(){
    console.log(9527);
})

Solution:

npm init -y
Add type(“type”:”module”,) in package. json

{
  "name": "serve",
  "version": "1.0.0",
  "description": "Server-side interface building for js phase projects",
  "main": "index.js",
   "type":"module",
  "scripts": {
    "node":"node app.js",
    "dev":"nodemon ./app.js"
  },
  "keywords": [
    "shop"
  ],
  "author": "wff",
  "license": "ISC",
  "devDependencies": {
    "express": "^4.17.3",
    "nodemon": "^2.0.15"
  }
}

The terminal runs node index.js or vs Code F5 can be run.
