PokeApiNet

A .Net wrapper for the Pokemon API at https://pokeapi.co.

Targets .Net Standard 2.0+.

Use

using PokeApiNet;

...

// instantiate client
PokeApiClient pokeClient = new PokeApiClient();

// get a resource by name
Pokemon hoOh = await pokeClient.GetResourceAsync<Pokemon>("ho-oh");

// ... or by id
Item clawFossil = await pokeClient.GetResourceAsync<Item>(100);

To see all the resources that are available, see the PokeAPI docs site.

Internally, PokeApiClient uses an instance of the HttpClient class. As such, instances of PokeApiClient are meant to be instantiated once and re-used throughout the life of an application.

Navigation URLs

PokeAPI uses navigation urls for many of the resource's properties to keep requests lightweight, but require subsequent requests in order to resolve this data. Example:

Pokemon pikachu = await pokeClient.GetResourceAsync<Pokemon>("pikachu");

pikachu.Species only has a Name and Url property. In order to load this data, an additonal request is needed; this is more of a problem when the property is a list of navigation URLs, such as the pikachu.Moves.Move collection.

GetResourceAsync includes overloads to assist with resolving these navigation properties. Example:

// to resolve a single navigation url property
PokemonSpecies species = await pokeClient.GetResourceAsync(pikachu.Species);

// to resolve a list of them
List<Move> allMoves = await pokeClient.GetResourceAsync(pikachu.Moves.Select(move => move.Move));

Paging

PokeAPI supports the paging of resources, allowing users to get a list of available resources for that API. Depending on the shape of the resource data, two methods for paging are included, along with overloads to allow for the specification of the page count limit and the page offset. Example:

// get a page of data (defaults to a limit of 20)
NamedApiResourceList<Berry> firstBerryPage = await client.GetNamedResourcePageAsync<Berry>();

// to specify a certain page, use the provided overloads
NamedApiResourceList<Berry> lotsMoreBerriesPage = await client.GetNamedResourcePageAsync<Berry>(60, 2);

Because the Berry resource has a Name property, the GetNamedResourcePageAsync() method is used. For resources that do not have a Name property, use the GetApiResourcePageAsync() method. Example:

ApiResourceList<ContestEffect> contestEffectPage = await client.GetApiResourcePageAsync<ContestEffect>();

Regardless of which method is used, the returning object includes a Results collection that can be used to pull the full resource data. Example:

Berry cheri = await client.GetResourceAsync<Berry>(firstBerryPage.Results[0]);

Refer to the PokeAPI documention to see which resources include a Name property.

IAsyncEnumerable Support

Two methods expose support for IAsyncEnumerable to make paging through all pages super simple: GetAllNamedResourcesAsync<T>() and GetAllApiResourcesAsync<T>(). Example:

await foreach (var berryRef in pokeClient.GetAllNamedResourcesAsync<Berry>())
{
    // do something with each berry reference
}

Caching

Every resource and page response is automatically cached in memory, making all subsequent requests for the same resource or page pull cached data. Example:

// this will fetch the data from the API
Pokemon mew = await pokeClient.GetResourceAsync<Pokemon>(151);

// another call to the same resource will fetch from the cache
Pokemon mewCached = await pokeClient.GetResourceAsync<Pokemon>("mew");

To clear the cache of data:

// clear all caches for both resources and pages
pokeClient.ClearCache();

Additional overloads are provided to allow for clearing the individual caches for resources and pages, as well as by type of cache.

Build

dotnet build

Test

The test bank includes unit tests and integration tests. Integration tests will actually ping the PokeApi server for data while the unit tests run off of mocked data.

dotnet test --filter "Category = Unit"
dotnet test --filter "Category = Integration"
