Creates a new kitsu instance

Parameters

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 requests
- options.query ("traditional" | "modern" | Function) Query serializer function to use. This will impact the way keys are serialized when passing arrays as query parameters. 'modern' is recommended for new projects. (optional, default traditional)
- options.camelCaseTypes boolean If enabled, type will be converted to camelCase from kebab-casae or snake_case (optional, default true)
- options.resourceCase ("kebab" | "snake" | "none") Case to convert camelCase to. kebab - /library-entries; snake - /library_entries; none-/libraryEntries` (optional, default kebab)
- options.pluralize boolean If enabled, /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)

Examples

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'
  }
})

plural

packages/kitsu/src/index.js:58-59

See: https://www.npmjs.com/package/pluralize for documentation
See: Kitsu constructor options for disabling pluralization

If pluralization is enabled (default, see Kitsu constructor docs) then pluralization rules can be added

Examples

Adding an uncountable pluralization rule

api.plural.plural('paper') //=> 'papers'
api.plural.addUncountableRule('paper')
api.plural.plural('paper') //=> 'paper'

headers

packages/kitsu/src/index.js:73-73

Get the current headers or add additional headers

Examples

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

interceptors

packages/kitsu/src/index.js:120-120

See: https://github.com/axios/axios#interceptors for documentation

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.

Examples

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)

get

packages/kitsu/src/index.js:218-246
