JSON.stringify()是可以让输出实现漂亮直观的json

let str = JSON.stringify(data,"","\t")

或者

let str = JSON.stringify(data,null,"\t")

例如

fs.writeFileSync('./package.json', JSON.stringify(packageJson, null, '\t'))

{
    "name": "app01",
    "version": "1.1.3",
    "description": "",
    "main": "index.js",
    "scripts": {
        "prepare": "husky install",
        "package_version_auto_add": "node package_version_auto_add.js"
    },
    "keywords": [],
    "author": "",
    "license": "ISC",
    "devDependencies": {
        "husky": "^7.0.4"
    }
}
