Verniy

Verniy is an unofficial Anilist GraphQL API library using Go. Verniy will generate graphql query string according to your request, make request to Anilist, parse reponse body, and convert to a struct.

The goal of this library is to make a flexible and easy to call Anilist API. This library may not cover all available API but you are always welcome to make a pull request.

This library is built using Anilist official docs especially the graphql reference.

Functions

There are alot of functions in verniy package but most of the time, you just need functions in Client struct. And it's recommended to use them to make your life easier. If you want to make a custom request, you can use function MakeRequest() (go to the function for more details).

Parameters

Yes, there are tons of custom types and functions but let your IDE auto-complete helps you choose the params for the functions. Not only constant value but also function (like MediaFieldTitle in the example) to fill the params. But, most of the functions have variadic parameters, so you don't need to actually fill it. There is already default value and you can read the code yourself to see the default value of the variadic parameters.

Response

Most of the functions in Client struct return a struct and error. Yes, most of the fields in the returned struct are pointers because, like any graphql, Anilist will not return fields that we didn't request. It is recommended to make your own pointer handler when using the field. For example.

// Handle *string to string.
func ptrToString(str *string) string {
    if str == nil {
        return ""
    }
    return *str
}

Rate Limit

Anilist has default rate limit 90 requests per minute. If you go over the rate limit you'll receive a 1-minute timeout. But, verniy has a built-in rate limiter to prevent the requests going over the limit. It will put your request on hold until the limit is available again.

OAuth2 Authentication

To access private user data, you need to use OAuth2 Access Token.

Read the Anilist OAuth2 documentation for more details.

The OAuth2 Access Token can be set in the Client struct.

c := verniy.New()
c.AccessToken = "your-access-token"

This token could also be used to update user data in the future.

Trivia

Verniy's name is taken from japanese destroyer. She is the 24th ship of the Fubuki class or the 2nd ship of the Akatsuki class. Originally, named Hibiki but later on, transferred to the Soviet Union and renamed to Верный (Verniy). Also, exists in Kantai Collection games and anime.
