## Overview `HangarClient` is a Java API client designed for interacting with the [Hangar](https://hangar.papermc.io/api-docs) platform.
It provides a comprehensive and intuitive interface for retrieving and managing Hangar projects, users, pages, statistics, API keys, and permissions. --- ## Table of Contents 1. [Setup](#setup) 2.

To force authentication, use `HangarClient#authenticate();`.
You only need to call it once, the client will automatically renew when it expires. ### JWT Authentication Use `JWTAuthProvider` for authentication with your API key: ```java JWTAuthProvider authProvider = new JWTAuthProvider("API_KEY"); ``` --- ## Client Initialization Initialize the client: ```java HangarClient client = HangarClient.builder() .auth(new JWTAuthProvider("")) .build(); ``` You can optionally use a custom HTTP client and set a custom User-Agent. --- ## Client Information Methods will return either a `CompletableFuture` or `RequestBuilder`. The `RequestBuilder` allows you to further customize the request before sending it.
> You need to use `#execute()` before getting the future. The `CompletableFuture` will return the response directly. This is used when further customization is not applicable. > Note that calling `#join()` on `CompletableFuture` will make a blocking call. >
> For async use `#whenComplete`, `thenAccept`, etc... --- ## Project Operations ### Retrieve All Projects ```java client.retrieveProjects() .execute() .join() .getProjects() .forEach(this::printProjectInfo); ``` ### Retrieve Specific Project ```java Project project = client.retrieveProject("ProjectName") .join() .getProject(); ``` Displays detailed project information such as avatar URL, category, timestamps, content, statistics, and more. ### Retrieve Project Members ```java client.retrieveMembers("ProjectName") .limit(10) .execute() .join() .getMembers() .forEach(member -> { String name = member.getUser(); UUID id = member.getUserId(); String role = member.getRoles().stream() .map(ProjectMemberRole::getTitle) .findAny() .orElse("N/A"); }); ``` ### Retrieve Watchers & Stargazers ```java // Watchers client.retrieveWatchers("ProjectName") .join() .getUsers(); // Stargazers client.retrieveStargazers("ProjectName") .join() .getUsers(); ``` ### Retrieve Project Stats ```java client.retrieveStats("ProjectName", Instant.EPOCH, Instant.now()) .join() .getStats() .forEach((platform, stats) -> { System.out.printf("%s: %d downloads, %d views\n", platform, stats.getDownloads(), stats.getViews()); }); ``` ### Page Retrieval ```java // Main page content String mainContent = client.retrievePage("ProjectName") .join() .getContent(); // Specific page String pageContent = client.retrievePage("ProjectName", "PageSlug") .join() .getContent(); ``` --- ## User Operations ### Retrieve All Users ```java UsersResponse users = client.retrieveUsers() .execute() .join(); users.getUsers().forEach(u -> System.out.println(u.getName())); ``` ### Retrieve Specific User ```java User user = client.retrieveUser("Username") .join() .getUser(); ``` ### Retrieve User Starred & Watching ```java // Starred projects client.retrieveUserStarred("Username") .execute() .join() .getProjects(); // Watching projects client.retrieveUserWatching("Username") .execute() .join() .getProjects(); ``` --- ## API Keys & Permissions ### Retrieve API Keys ```java client.retrieveKeys() .join() .getKeys() .forEach(key -> System.out.println(key.getName())); ``` ### Check Permissions ```java client.hasPermissions() .fromProject("ProjectName") .withPermissions(Permission.EDIT_API_KEYS, Permission.VIEW_PUBLIC_INFO) .execute() .thenAccept(response -> { System.out.println("Allowed: " + response.getResult()); }) .join(); ``` ### Retrieve Permissions ```java client.retrievePermissions() .fromProject("ProjectName") .execute() .thenAccept(response -> { System.out.println("Binary String: " + response.getPermissionBinString()); response.getPermissions().forEach(p -> System.out.println("Allowed: " + p.name())); }) .join(); ``` --- ## Model Classes *Models are entities from hangar wrapped in java classes for ease of use.* * `APIKey` - Represents an API Key. * `Project` - Represents a project. * `User` - Represents a user. * `UserProject` - Represents a user project. Unlike Project, this holds less information. * `ProjectMember` - Represents a user with roles on a project. * `NameHistory` - Represents name history data from a user. --- ## Further Reading * [Hangar API GitHub Repository](https://github.com/TheSilentPro/hangar-api) * [API Reference Documentation](https://hangar.papermc.io/api-docs)
