"description": "An App",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"engines": {
"node": "0.10.x",
"npm": "1.3.x"
},
"author": "An author",

"jade": "~0.35.0",
"express": "~3.4.4",
"stylus": "~0.40.2",
"mongoose": "~3.8.0",
"passport-local": "~0.1.6",

},

}
}
How do I change the "name": attribute "Original Name" to "New Name" without breaking npm install ?
I tried simply updating the name and attempting npm install but npm install won't read the package.json file now.
Thanks in advance

Answer 1

just edit the name in package.json.
The name must following the rules https://docs.npmjs.com/files/package.json#name

Answer 2

Just change the name in package.json file. Changes to the package should come along with changes to the version.
Once you change the name in package.json, the name and/or version properties in package-lock.json should also be changed. This can be done by simply running npm install
From npm docs
Some rules:
The name must be less than or equal to 214 characters. This includes the scope for scoped packages.
The names of scoped packages can begin with a dot or an underscore. This is not permitted without a scope.
New packages must not have uppercase letters in the name.
The name ends up being part of a URL, an argument on the command line, and a folder name. Therefore, the name can't contain any non-URL-safe characters.
