I installed babel packages as below.

package.json:

  "dependencies": {
    "@babel/preset-react": "^7.16.7",
    "@prisma/client": "^3.8.1",
    "apollo-server": "^3.6.2",
    "graphql": "^16.2.0"
  },
  "devDependencies": {
    "@babel/core": "^7.16.7",
    "@babel/node": "^7.16.8",
    "@babel/preset-env": "^7.16.8",
    "babel-preset-react": "^6.24.1",
    "nodemon": "^2.0.15",
    "prisma": "^3.8.1"
  }

and I made babel.config.json file.

babel.config.json:

{
  "presets": ["@babel/preset-env"]
}

I did the same as babel Node API should be done according to official doc:https://babeljs.io/setup#installation

But I got the error message:

SyntaxError: /Users/hayat/Desktop/chungchunon-backend/server.js: Unexpected keyword 'const'. (40:0)

}

It seems that due to the BABEL_PARSE_ERROR, it can't read const. But as I installed all necessary babel package, I can't understand why.
