packages.json file code example

Example 1: change name in package json from command line

cd some/node/project

# Get stuff from package.json
npe name
npe scripts
npe scripts.test
npe repository.url
open $(npe repository.url)

# Set stuff in package.json
npe name foo
npe scripts.start "node index.js"

# Keywords string will be turned into an array
# If commas are present, they'll be the delimiter. Otherwise spaces.
npe keywords "foo, bar, cheese whiz"
npe keywords "foo bar baz"

# The current working directory's package.json is used by default,
# but you can point to another package file with a flag:
npe name --package=some/other/package.json
npe name other --package=some/other/package.json

Example 2: what is package.json in node

All npm packages contain a file, usually in the project root, called package. json - this file holds various metadata relevant to the project. This file is used to give information to npm that allows it to identify the project as well as handle the project's dependencies.

Example 3: packages.json from file

{ "dependencies" :  { "foo" : "1.0.0 - 2.9999.9999"  , "bar" : ">=1.0.2 <2.1.2"  , "baz" : ">1.0.2 <=2.3.4"  , "boo" : "2.0.1"  , "qux" : "<1.0.0 || >=2.3.1 <2.4.5 || >=2.5.2 <3.0.0"  , "asd" : "http://asdf.com/asdf.tar.gz"  , "til" : "~1.2"  , "elf" : "~1.2.3"  , "two" : "2.x"  , "thr" : "3.3.x"  , "lat" : "latest"  , "dyl" : "file:../dyl"  }}
