A wrapper around the IGDBv4 API using .NET Core (compatible with .NET Standard 2.0+). Note, IGDBv3 is now deprecated and no longer supported so previous versions of this library (1.x) are no longer supported.
I built this library primarily for Keep Track of My Games, an app to help organize and track your game collection. That means I use this library in production and I'm motivated to keep it up-to-date and fix issues.
via Nuget
# .NET Core
dotnet add package IGDB
# .NET Framework
Install-Package IGDB
# Paket
paket add IGDB
Uses RestEase so you can easily call the API methods. Since IGDB uses APIcalypse query language, you will need to pass the query as a string. TODO: Create a query builder.
Endpoints can be passed using the constants in IGDB.IGDBClient.Endpoints or as a custom string.
Models are domain objects found in IGDB.Models and correspond directly to the Endpoints documentation.
Some fields can be expanded which is handled via the IdentityOrValue and IdentitiesOrValues wrapper.
The IGDB API uses the Twitch Developer program to power its API so it requires an OAuth client app ID and secret, which you can find in your Developer Portal. Passing these to the IGDBClient constructor will handle the OAuth bearer token management for you (see Custom Token Management below for details).
See below for an example:
using IGDB;
using IGDB.Models;
var igdb = new IGDBClient(
// Found in Twitch Developer portal for your app
Environment.GetEnvironmentVariable("IGDB_CLIENT_ID"),
Environment.GetEnvironmentVariable("IGDB_CLIENT_SECRET")
);
// Simple fields
var games = await igdb.QueryAsync<Game>(IGDBClient.Endpoints.Games, query: "fields id,name; where id = 4;");
var game = games.First();
game.Id; // 4
game.Name; // Thief
// Reference fields
var games = await igdb.QueryAsync<Game>(IGDBClient.Endpoints.Games, query: "fields id,name,cover; where id = 4;");
var game = games.First();
game.Cover.Id.HasValue; // true
game.Cover.Id.Value; // 65441
// Expanded fields
var games = await igdb.QueryAsync<Game>(IGDBClient.Endpoints.Games, query: "fields id,name,cover.*; where id = 4;");
var game = games.First();
// Id will not be populated but the full Cover object will be
game.Cover.Id.HasValue; // false
game.Cover.Value.Width; // 756
game.Cover.Value.Height;By default this client will request a OAuth bearer token on your behalf that is valid for 60 days and will store it statically in memory. If an invalid token is used and a 401 response is received, it will automatically acquire a new token and retry the request. See TokenManagement.cs for the default implementation.
To customize this behavior, such as storing the bearer token in persistent storage like SQL or NoSQL, you will have to pass your own ITokenStore implementation.
using IGDB;
class CustomTokenStore : ITokenStore {
Task<TwitchAccessToken> GetTokenAsync() {
// Get token from database, etc.
var token = // ...
return token;
}
Task<TwitchAccessToken> StoreTokenAsync(TwitchAccessToken token) {
// Store new token in database, etc.
return token;
}
}
// Create an IGDB API client, passing custom token store
var api = new IGDBClient(clientId, clientSecret, new CustomTokenStore());GetTokenAsync- Gets a tokenStoreTokenAsync- Stores a new token
When using dependency injection, the lifetime of the ITokenStore can be whatever you prefer -- a singleton is used by default.
Note: If you build a token store, please open a PR and add a link here so others can use it!
IGDB uses some interesting patterns to serialize responses. When using field expansion (foo.*) it will expand that JSON property to be an array of objects instead of just an array of IDs. The default serializer settings of this client will handle all of this for you. It also handles serializing/deserializing snake_case naming and Unix timestamps.
To get a reference to the default serializer settings (for example, to serialize/deserialize yourself separately), you can access the static variable IGDBClient.DefaultJsonSerializerSettings.
Use the IGDB.ImageHelper to generate URLs for images. It exposes the raw template URL IGDB_IMAGE_TEMPLATE and mapping ImageSizeMap of ImageSize enum to string value:
var games = await igdb.QueryAsync<Game>(IGDB.IGDBClient.Endpoints.Games, query: "fields artworks.image_id; where id = 4;");
var artworkImageId = games.First().Artworks.Values.First().ImageId;
// Thumbnail
var thumb = IGDB.ImageHelper.GetImageUrl(imageId: artworkImageId, size: ImageSize.Thumb, retina: false);
var thumb2X = IGDB.ImageHelper.GetImageUrl(imageId: artworkImageId, size: ImageSize.Thumb, retina: true);
// Covers
var coverSmall = IGDB.ImageHelper.GetImageUrl(imageId: artworkImageId, size: ImageSize.CoverSmall, retina: false);- .NET Core SDK 2.2.5
- Visual Studio Code or VS 2017+
Add environment variables:
export IGDB_CLIENT_ID=[your OAuth app client ID]
export IGDB_CLIENT_SECRET=[your OAuth app client secret]
These are found in your Twitch Developer Console.
You don't need this to be defined globally but it does need to be in scope while running dotnet test.
