How to write json correctly?

Question

JSON

Hello!
I'm learning webpack and I want to connect the node-static plugin so that it passes parameters to headers. I follow the instructions as here: (at the very end) https://github.com/cloudhead/node-static
This is how I write it in my package.json

{
  "name": "webpack-app",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "scripts": {
    "start": "webpack --mode production --watch",
    "dev": "webpack --mode development",
    "serv": "static -H '{"Cache-Control": "no-cache, must-revalidate"}'" // Данная строка
  },
  "devDependencies": {
    "html-webpack-plugin": "^3.2.0",
    "node-static": "^0.7.11",
    "webpack": "^4.39.2",
    "webpack-cli": "^3.3.6"
  }
}

But the editor swears and an error occurs when starting ... then I escaped the double quotes

"serv": "static -H '{\"Cache-Control\": \"no-cache, must-revalidate\"}'"

Gives an error message

undefined:1
'{Cache-Control:
^
SyntaxError: Unexpected token ' in JSON at position 0
........

Tried double quotes instead of single quotes before "{"Cache-Control" ..... }"

undefined:1
{Cache-Control: no-cache,
 ^
SyntaxError: Unexpected token C in JSON at position 1

I understand that somewhere in the syntax there is an error, tell me how to write this line correctly?

{
"name": "webpack-app",
"version": "1.0.0",
"main": "index.js",
"license": "MIT",
"scripts": {
"start": "webpack --mode production --watch",
"dev": "webpack --mode development",
"serv": "static -H \"{\"Cache-Control\": \"no-cache, must-revalidate\ "}\""
},
"devDependencies": {
"html-webpack-plugin": "^3.2.0",
"node-static": "^0.7.11",
"webpack": "^4.39.2" ,
"webpack-cli": "^3.3.6"
}
}
in the future I recommend using an editor like this
