Description

This library helps you retrieve the most frequently extracted metadata and icons within iOS, Android and UWP applications.

Usage

import

import { Extract } from 'app-metadata';

usage

let results = await Extract.run(pathName);

This library relies on the standard set of file extensions to determine the type of package it is analyzing.

Results

The library will return the information most relevant for the supported platforms. For a better understanding of the details retrieved refer to the tables below.

iOS

Supported extension: .ipa

Property	Description
icon
iconName
languages	Array of language strings compiled from .lproj files
hasProvisioning	Should always be true since IPA will contain a provisioning profile
appex_provisioning_profiles	Array of all other provisioning profiles included in the metadata

• from Plist (info.plist):

Property	Description
displayName	CFBundleDisplayName (The user-visible name of the bundle) or CFBundleName (short bundle name)
uniqueIdentifier	CFBundleIdentifier (reverse DNS that identifies a project by concatenating the company identifier with the product name)
version	CFBundleShortVersionString (The release-version-number string for the bundle)
buildVersion	CFBundleVersion (The build-version-number string for the bundle)
executableName	CFBundleExecutable (Name of the bundle’s executable file)
minimumOsVersion	MinimumOSVersion or LSMinimumSystemVersion
deviceFamily	UIdeviceFamily

• from Provisioning Profile (embedded.mobileprovision):

Property	Description
pathName	Path of the provisioning profile from inside of the IPA
mobileProvisionFileContent	Provisioning profile content
teamIdentifier	Entitlements["com.apple.developer.team-identifier"]
profileType	If data.ProvisionedDevices exists, "adhoc". Otherwise "enterprise"
expiredAt	expired_at or ExpirationDate
idName	AppIDName
name	Name
UniqueDeviceIdentifierList	ProvisionedDevices
deviceFamily	Platform

Android

Supported extension: .apk

• from Manifest:

Property	Description
icon
iconName
uniqueIdentifier	package
version	versionName
buildVersion	versionCode
minimumOsVersion	usesSdk.minSdkVersion
deviceFamily	"android"

UWP

Supported extensions: .appx, appxupload or .zip

from Manifest:

Property	Description
deviceFamily	Constants.WINDOWS
displayName	Package.Properties.DisplayName
iconFullPath	Package.Properties.Logo
uniqueIdentifier	Package.Identity.Name
buildVersion	Package.Identity.Version
minimumOsVersion	Package.Prerequisites.OSMinVersion or Package.Dependencies.TargetDeviceFamily.MinVersion
executableName	Package.Applications.Application.Executable
languages	Built from Package.Resources.Resource.Language

UWP Bundles

Supported extensions: .appxbundle, appxupload or .zip

For .appxbundle app packages, the manifest is checked for the correct name of the appx subpackage. If it is found, the metadata is parsed directly from there, otherwise we scavenge for as much as we can get from the appxbundle manifest and metadata

Property	Description
icon
iconName
languages	Built from .appx language files. Example- VLC_WinRT.WindowsPhone_1.8.4.0_language-en.appx

from Manifest:

Property	Description
deviceFamily	windows
uniqueIdentifier	Bundle.Identity.Name
buildVersion	Bundle.Identity.Version
minimumOsVersion	Bundle.Prerequisites.OSMinVersion or Bundle.Dependencies.TargetDeviceFamily

The assumption for zip and appxUpload is that the unziped folders will have the appx or appxbundle which we will then process as we do normally
