If you're working with Kitsu.io's API, their API docs lists all available resources with their attributes and relationships
packages/kitsu/src/index.js:30-447
Creates a new kitsu instance
options Object? Options (optional, default {})
options.baseURL string Set the API endpoint (optional, default https://kitsu.io/api/edge)options.headers Object? Additional headers to send with the requestsoptions.camelCaseTypes boolean If true, the type value will be camelCased, e.g library-entries and library_entries become libraryEntries (optional, default true)options.resourceCase string kebab, snake or none. If kebab, /libraryEntries will become /library-entries. If snake, /libraryEntries will become /library_entries, If none, /libraryEntries will be unchanged (optional, default kebab)options.pluralize boolean If true, /user will become /users in the URL request and type will be pluralized in POST, PATCH and DELETE requests (optional, default true)options.timeout number Set the request timeout in milliseconds (optional, default 30000)options.axiosOptions Object? Additional options for the axios instance (see axios/axios#request-config for details)Using with Kitsu.io's API
const api = new Kitsu()
Using another API server
const api = new Kitsu({
baseURL: 'https://api.example.org/2'
})
Setting headers
const api = new Kitsu({
headers: {
'User-Agent': 'MyApp/1.0.0 (github.com/username/repo)',
Authorization: 'Bearer 1234567890'
}
})
packages/kitsu/src/index.js:52-53
If pluralization is enabled (default, see Kitsu constructor docs) then pluralization rules can be added
Adding an uncountable pluralization rule
api.plural.plural('paper') //=> 'papers'
api.plural.addUncountableRule('paper')
api.plural.plural('paper') //=> 'paper'
packages/kitsu/src/index.js:67-67
Get the current headers or add additional headers
Get all headers
api.headers
Get a single header's value
api.headers['User-Agent']
Add or update a header's value
api.headers['Authorization'] = 'Bearer 1234567890'
Returns Object All the current headers
packages/kitsu/src/index.js:112-112
Axios Interceptors (alias of axios.interceptors)
You can intercept responses before they are handled by get, post, patch and delete and before requests are sent to the API server.
Request Interceptor
// Add a request interceptor
api.interceptors.request.use(config => {
// Do something before request is sent
return config
}, error => {
// Do something with the request error
return Promise.reject(error)
})
Response Interceptor
// Add a response interceptor
api.interceptors.response.use(response => {
// Any status code that lie within the range of 2xx cause this function to trigger
// Do something with response data
return response
}, error => {
// Any status codes that falls outside the range of 2xx cause this function to trigger
// Do something with response error
return Promise.reject(error)
})
Removing Interceptors
const myInterceptor = api.interceptors.request.use(function () {...})
api.interceptors.request.eject(myInterceptor)
packages/kitsu/src/index.js:185-204

})

const { data } = await api.get('anime')
