OpenGraphReader

OpenGraphReader is a Swift library that allows you to easily extract OpenGraph metadata from HTML content. OpenGraph metadata provides structured information about a web page's content when shared on social media platforms.

Features

• Fetches OpenGraph metadata from a URL or a URLRequest.
• Parses HTML content to extract various OpenGraph properties such as title, type, description, URL, images, site name, and more.
• Provides convenient extensions for accessing OpenGraph properties in a structured manner.

Installation

Installing via Swift Package Manager (SPM)

You can easily integrate OpenGraphReader into your project using Swift Package Manager:

1. Open your Xcode project.
2. Click on "File" > "Swift Packages" > "Add Package Dependency..."
3. Enter the URL of this repository: https://github.com/pzmudzinski/OpenGraphReader.git
4. Choose "Up To Next Major Version": 1.0.0
5. Click "Add Package"

Usage

Fetching OpenGraph Metadata

To fetch and parse OpenGraph metadata from a URL:

import OpenGraphReader

let reader = OpenGraphReader()
do {
    let openGraphResponse = try await reader.fetch(url: .init(string: "https://www.imdb.com/title/tt15398776/?ref_=ext_shr_lnk"))
    // Access OpenGraph properties using openGraphResponse properties
    print("Title: \(openGraphResponse.title ?? "")")
    print("Description: \(openGraphResponse.description ?? "")")
    // ...
} catch {
    print("Error: \(error)")
}

Using HTML directly

If you already have HTML you can pass it to reader as well:

let response = try reader.parse(html: "...")

Getting non default meta tags

If OpenGraphResponse does not have all properties you need you can directly access all meta tags (including those not being part of OpenGraph specification) by using one of those helper methods:

response.stringValue("twitter:image")
response.arrayValue("twitter:tag")
response.doubleValue("twitter:image:height")
response.urlValue("twitter:image:url")

Requirements

• iOS 15.0+ / macOS 12.0+
• Swift 5+
