The following exports are available.

packageJson.fromDirectory()

Load the package.json file present in a given directory.

(path: string) => Promise<PackageJson>

The path argument is required and must be an accessible folder that contains a package.json file.

const pkg = await packageJson.fromDirectory('/path/to/my/repo');
// { name: 'my-package', version: '1.0.0', ... }

packageJson.fromFile()

Load the package.json file at a given file path.

(path: string) => Promise<PackageJson>

The path argument is required and must be an accessible JSON file.

const pkg = await packageJson.fromFile('/path/to/my/repo/package.json');
// { name: 'my-package', version: '1.0.0', ... }

packageJson.fromString()

Parse a JSON string as a package.json file.

(jsonString: string) => PackageJson

The jsonString argument is required and must be valid JSON.

const pkg = await packageJson.fromString('{"name": "my-package", "version": "1.0.0"}');
// { name: 'my-package', version: '1.0.0' }

packageJson.fromObject()

Verify whether a JavaScript object meets the basic standards for a package.json file (e.g. has a name and version property).

(object: any) => PackageJson

The jsonString argument is required and must be valid JSON.

const pkg = await packageJson.fromObject({
    name: 'my-package',
    version: '1.0.0'
});
// { name: 'my-package', version: '1.0.0' }

const pkg = await packageJson.fromObject({});

packageLock.fromDirectory()

Load the package-lock.json file present in a given directory.

(path: string) => Promise<PackageLock>

The path argument is required and must be an accessible folder that contains a package-lock.json file.

const pkg = await packageLock.fromDirectory('/path/to/my/repo');
// { lockfileVersion: 3, name: 'my-package', version: '1.0.0', ... }

packageLock.fromFile()

Load the package-lock.json file at a given file path.

(path: string) => Promise<PackageLock>

The path argument is required and must be an accessible JSON file.

const pkg = await packageLock.fromFile('/path/to/my/repo/package-lock.json');
// { lockfileVersion: 3, name: 'my-package', version: '1.0.0', ... }

packageLock.fromString()

Parse a JSON string as a package-lock.json file.

(jsonString: string) => PackageLock

The jsonString argument is required and must be valid JSON.

const pkg = await packageLock.fromString('{"lockfileVersion": 3, "name": "my-package", "version": "1.0.0"}');
// { lockfileVersion: 3, name: 'my-package', version: '1.0.0' }

packageLock.fromObject()

Verify whether a JavaScript object meets the basic standards for a package-lock.json file (e.g. has a valid lockfileVersion, name and version property).

(object: any) => PackageLock

The jsonString argument is required and must be valid JSON.

const pkg = await packageLock.fromObject({
    lockfileVersion: 3,
    name: 'my-package',
