API

readPackage(options?)

Returns a Promise<object> with the parsed JSON.

readPackageSync(options?)

Returns the parsed JSON.

options

Type: object

cwd

Type: URL | string
Default: process.cwd()

Current working directory.

normalize

Type: boolean
Default: true

Normalize the package data.

parsePackage(packageFile, options?)

Parses an object or string into JSON.

Note: packageFile is cloned using structuredClone to prevent modification to the input object. This function is available from Node.js 18 on. In environments without structuredClone (such as Node.js 16), a shallow spread is used instead, which can cause deep properties of the object to be modified. Consider cloning the object before using parsePackage if that's the case.

packageFile

Type: object | string

An object or a stringified object to be parsed as a package.json.

options

Type: object

normalize

Type: boolean
Default: true

Normalize the package data.
