Install
Install with npm (requires Node.js >= 0.10.0):
$ npm install --save normalize-pkgInstall
Install with bower
$ bower install normalize-pkg --saveUsage
var config = require('./')();
var pkg = config.normalize(require('./package'));Features
Normalizes most package.json fields, and:
- converts
repositoryobjects to a string - stringifies
authorobject - stringifies each "person" object in
maintainers,contributorsandcollaborators - converts
licensesarrays and objects to alicensestring - removes files that don't exist from
bin,mainand thefilesarray - adds
cli.jstobinif it exists - creates
keywordsarray fromnameif not defined
See the schema, normalizers, and unit tests for more examples.
Schema
Values are normalized using a schema that is passed to map-schema.
- only properties that have a corresponding field on the schema will be normalized.
- any properties that do not have a corresponding field are returned unmodified.
See the .field docs to learn how to add or overwrite a field on the schema.
Defaults
A default value may optionally be defined when a .field is registered. When .normalize is run and a property that is required or recommended by npm is missing, normalize-pkg attempts to create the field if valid data can be found in the repository.
built-in fields have a default value:
version:'0.1.0'license:'MIT'engines:{node: '>= 0.10.0'}
For example:
name: the project-name library is used to fill in the namebin: if empty, populated withcli.jsorbinif either exists on the file system
Example
The following:
var config = require('./')();
// no package.json is passed, just an empty object
var pkg = config.normalize({});
console.log(pkg);Results
Since an empty object was passed, normalize-pkg was smart enough to fill in missing fields looking for info in the project. In this case, specifically from parsing .git config and using any defaults defined on the schema.

Params
name{String}: Field name (required)type{String|Array}: One or more native javascript types allowed for the property value (required)options{Object}returns{Object}: Returns the instance
Example
const config = new NormalizePkg();
config.field('foo', 'string', {
default: 'bar'
});
const pkg = config.normalize({});

pkg{Object}: Thepackage.jsonobject to normalizeoptions{Object}returns{Object}: Returns a normalized package.json object.
Example
const config = new NormalizePkg();
const pkg = config.normalize(require('./package.json'));Options
options.knownOnly
Type: boolean
Default: undefined
Omit properties from package.json that do not have a field registered on the schema.
var Config = require('normalize-pkg');
var config = new Config({knownOnly: true});
var pkg = config.normalize({name: 'my-project', foo: 'bar'});
console.log(pkg);
//=> {name: 'my-project'}options.pick
Type: array
Default: undefined
Filter the resulting object to contain only the specified keys.
options.omit
Type: array
Default: undefined
Remove the specified keys from the resulting object.
options.fields
Pass a fields object on the options to customize any fields on the schema (also see options.extend):
var pkg = config.normalize(require('./package'), {
extend: true,
fields: {
name: {
normalize: function() {
return 'bar'
}
}
}
});
console.log(pkg.name);
//=> 'bar'options.extend
Type: boolean
Default: undefined
Used with options.field, pass true if you want to extend a field that is already defined on the schema.
var pkg = config.normalize(require('./package'), {
extend: true,
fields: {
name: {
normalize: function() {
return 'bar'
}
}
}
});
console.log(pkg.name);
//=> 'bar'About
