    Modern fetch-based alternative to axios/superagent/request. Great for React Native.

    New in v2.0.4++: baseURI is now optional and you can pass raw: true as a global or request-based option to get the raw fetch() response (e.g. if you want to use res.arrayBuffer() or any other method manually).

    const Frisbee = require('frisbee');

    Frisbee is a function that optionally accepts an argument options, which is an object full of options for constructing your API instance.

    • Frisbee - accepts an options object, with the following accepted options:

      • baseURI (String) - the default URI to use as a prefix for all HTTP requests (optional as of v2.0.4+)

        • If your API server is running on http://localhost:8080, then use that as the value for this option

        • If you use React Native, then you most likely want to set baseURI as follows (e.g. making use of __DEV__ global variable):

          const api = new Frisbee({
            baseURI: __DEV__
              ? process.env.API_BASE_URI || 'http://localhost:8080'
              : ''
        • You could also set API_BASE_URI as an environment variable, and then set the value of this option to process.env.API_BASE_URI (e.g. API_BASE_URI=http://localhost:8080 node app)

        • Using React Native? You might want to read this article about automatic IP configuration.

      • headers (Object) - an object containing default headers to send with every request

        • Tip: You'll most likely want to set the "Accept" header to "application/json" and the "Content-Type" header to "application/json"
      • body (Object) - an object containing default body payload to send with every request. Either the default body set in options will be used or it will be overridden with a request provided body. Body will not merge nor deep merge.

      • params (Object) - an object containing default querystring parameters to send with every request (API method specific params options will override or extend properties defined here, but will not deep merge)

      • logRequest (Function) - a function that accepts two arguments path (String) and opts (Object) and will be called with before a fetch request is made with (e.g. fetch(path, opts) – see Logging and Debugging below for example usage) - this defaults to false so no log request function is called out of the box

      • logResponse (Function) - a function that accepts three arguments path (String), opts (Object), and response (Object) and has the same parameters as logRequest, with the exception of the third response, which is the raw response object returned from fetch (see Logging and Debugging below for example usage) - this defaults to false so no log response function is called out of the box

      • auth - will call the auth() function below and set it as a default

      • parse - options passed to qs.parse method (see qs for all available options)

        • ignoreQueryPrefix (Boolean) - defaults to true, and parses querystrings from URL's properly
      • stringify - options passed to qs.stringify method (see qs for all available options)

        • addQueryPrefix (Boolean) - defaults to true, and affixes the path with required ? parameter if a querystring is to be passed

        • format (String) - defaults to RFC1738

        • arrayFormat (String) - defaults to 'indices'

      • preventBodyOnMethods (Array) - defaults to [ 'GET', 'HEAD', 'DELETE', 'CONNECT' ], and is an Array of HTTP method names that we will convert a body option to be querystringified URL parameters (e.g. api.get('/v1/users', { search: 'foo' }) will result in GET /v1/users?search=foo). According to RFC 7231, the default methods defined here have no defined semantics for having a payload body, and having one may cause some implementations to reject the request (which is why we set this as a default). If you wish to disable this, you may pass preventBodyOnMethods: false or your own custom Array preventBodyOnMethods: [ ... ]

      • interceptableMethods (Array) - defaults to all API methods supported below (defaults to GET, HEAD, POST, PUT, DELETE, OPTIONS, PATCH)

      • raw (Boolean) - return a raw fetch response (new as of v2.0.4+)

      • abortToken (Symbol) - some Symbol that you can use to abort one or more frisbee requests

      • signal (Object) - an AbortController Signal used to cancel a fetch request

      • mode (String) - passed to fetch, defaults to "same-origin" (see Fetch's documentation for more info)

      • cache (String) - passed to fetch, defaults to "default" (see Fetch's documentation for more info)

      • credentials (String) - passed to fetch, defaults to "same-origin" (see Fetch's documentation for more info)

      • redirect (String) - passed to fetch, defaults to "follow" (see Fetch's documentation for more info)

      • referrer (String) - passed to fetch, defaults to "client" (see Fetch's documentation for more info)

    Upon being invoked, Frisbee returns an object with the following chainable methods:

    • api.auth(creds) - helper function that sets BasicAuth headers, and it accepts user and pass arguments

      • You can pass creds user and pass as an array, arguments, or string: ([user, pass]), (user, pass), or ("user:pass"), so you shouldn't have any problems!
      • If you don't pass both user and pass arguments, then it removes any previously set BasicAuth headers from prior auth() calls
      • If you pass only a user, then it will set pass to an empty string '')
      • If you pass : then it will assume you are trying to set BasicAuth headers using your own user:pass string
      • If you pass more than two keys, then it will throw an error (since BasicAuth only consists of user and pass anyways)
    • api.setOptions(opts) - helper function to update instance options (note this does not call api.auth internally again even if opts.auth is passed)

    • api.jwt(token) - helper function that sets a JWT Bearer header. It accepts the jwt_token as a single string argument. If you simply invoke the function null as the argument for your token, it will remove JWT headers.

    • api.abort(token) - aborts all current/queued requests that were created using token

    • api.abortAll() - aborts all current/queued - i.e. await-ing in an interceptor - requests

    • All exposed HTTP methods return a Promise, and they require a path string, and accept an optional options object:

      • Accepted method arguments:

        • path required - the path for the HTTP request (e.g. /v1/login, will be prefixed with the value of baseURI if set)

        • options optional - an object containing options, such as header values, a request body, form data, or a querystring to send along with the request. These options by default are inherited from global options passed to new Frisbee({ options }). For the GET method (and the DELETE method as of version 1.3.0), body data will be encoded in the query string. **This options object is passed to the native Fetch API method, which means you can use native Fetch API method options as well from Fetch's documentation

          To make only a certain request be raw and not parsed by Frisbee:

          const res = await api.get('/v1/messages', { raw: false });

          Here are a few examples (you can override/merge your set default headers as well per request):

          • To turn off caching, pass cache: 'reload' to native fetch options:

            const res = await api.get('/v1/messages', { cache: 'reload' });
          • To set a custom header value of X-Reply-To on a POST request:

            const res = await'/messages', {
              headers: {
                'X-Reply-To': '7s9inuna748y4l1azchi'
        • raw optional - will override a global raw option if set, and if it is true it will return a raw fetch response (new as of v2.0.4+)

      • List of available HTTP methods:

        • api.get(path, options) - GET
        • api.head(path, options) - HEAD (does not currently work - see tests)
        •, options) - POST
        • api.put(path, options) - PUT
        • api.del(path, options) - DELETE
        • api.delete(path, options) - DELETE
        • api.options(path, options) - OPTIONS (does not currently work - see tests)
        • api.patch(path, options) - PATCH
      • Note that you can chain the auth method and a HTTP method together:

        const res = await api.auth('foo:bar').get('/');
    • interceptor - object that can be used to manipulate request and response interceptors. It has the following methods:

      • api.interceptor.register(interceptor): Accepts an interceptor object that can have one or more of the following functions

        request: function (path, options) {
            // Read/Modify the path or options
            // ...
            return [path, options];
        requestError: function (err) {
            // Handle an error occured in the request method
            // ...
            return Promise.reject(err);
        response: function (response) {
            // Read/Modify the response
            // ...
            return response;
        responseError: function (err) {
            // Handle error occured in api/response methods
            return Promise.reject(err);

        the register method returns an unregister() function so that you can unregister the added interceptor.

      • api.interceptor.unregister(interceptor): Accepts the interceptor reference that you want to delete.

      • api.interceptor.clear(): Removes all the added interceptors.

      • Note that when interceptors are added in the order ONE->TWO->THREE:

        • The request/requestError functions will run in the same order ONE->TWO->THREE.
        • The response/responseError functions will run in reversed order THREE->TWO->ONE.

    Logging and Debugging

    We highly recommend to use CabinJS as your Node.js and JavaScript logging utility (see Automatic Request Logging for complete examples).

    Logging Requests and Responses

    You can log both requests and/or responses made to fetch internally in Frisbee. Simply pass a logRequest and/or logResponse function.

    logRequest accepts two arguments path (String) and opts (Object) and these two arguments are what we call fetch with internally (e.g. fetch(path, opts)):

    const cabin = require('cabin');
    const frisbee = require('frisbee');
    const pino = require('pino')({
      customLevels: {
        log: 30
      hooks: {
        // <>
        logMethod(inputArgs, method) {
          return, {
            // <>
            // message: inputArgs[0],
            msg: inputArgs[0],
            meta: inputArgs[1]
    const logger = new Cabin({
      // (optional: your free API key from
      // key: 'YOUR-CABIN-API-KEY',
      axe: { logger: pino }
    const api = new Frisbee({
      logRequest: (path, opts) => {'fetch request', { path, opts });

    logResponse accepts three arguments, the first two are the same as logRequest (e.g. path and opts), but the third argument is response (Object) and is the raw response object returned from fetch (e.g. const response = await fetch(path, opts)):

    const cabin = require('cabin');
    const frisbee = require('frisbee');
    const pino = require('pino')({
      customLevels: {
        log: 30
    const logger = new Cabin({
      // (optional: your free API key from
      // key: 'YOUR-CABIN-API-KEY',
      axe: { logger: pino }
    const api = new Frisbee({
      logResponse: (path, opts, res) => {'fetch response', { path, opts, res });

    Frequently Asked Questions

    How do I unset a default header

    Simply set its value to null, '', or undefined – and it will be unset and removed from the headers sent with your request.

    A common use case for this is when you are attempting to use FormData and need the content boundary automatically added.

    Why do my form uploads randomly fail with React Native

    This is due to a bug with setting the boundary. For more information and temporary workaround if you are affected please see facebook/react-native#7564 (comment).

    Does this support callbacks, promises, or both

    As of version 1.0.0 we have dropped support for callbacks, it now only supports Promises.

    What is the fetch method

    It is a WHATWG browser API specification. You can read more about at the following links:

    Does the Browser or Node.js support fetch yet

    Yes, a lot of browsers are now supporting it! See this reference for more information

    If my engine does not support fetch yet, is there a polyfill

    Yes you can use the fetch method (polyfill) from whatwg-fetch or node-fetch.

    By default, React Native already has a built-in fetch out of the box!

    Can I make fetch support older browsers

    Yes, but you'll need a promise polyfill for older browsers.

    What is this project about

    Use this package as a universal API wrapper for integrating your API in your client-side or server-side projects.

    It's a better working alternative (and with less headaches; at least for me) – for talking to your API – than superagent and the default fetch Network method provide.

    Use it for projects in Node, React, Angular, React Native, ...

    It supports and is tested for both client-side usage (e.g. with Bower, Browserify, or Webpack, with whatwg-fetch) and also server-side (with node-fetch).

    Why not just use superagent or fetch

    See Background for more information.

    Want to build an API back-end with Node.js

    See Lad as a great starting point, and read this article about building Node.js API's with authentication.

    Need help or want to request a feature

    File an issue on GitHub and we'll try our best help you out.


    This package is tested to work with whatwg-fetch and node-fetch.

    This means that it is compatible for both client-side and server-side usage.


    1. Fork/clone this repository
    2. Run npm install
    3. Run npm run watch to watch the src directory for changes
    4. Make changes in src directory
    5. Write unit tests in /test/ if you add more stuff
    6. Run npm test when you're done
    7. Submit a pull request


    The docs suggest that you use superagent with React Native, but in our experience it did not work properly, therefore we went with the next best solution, the Github fetch API polyfill included with React Native. After having several issues trying to use fetch and writing our own API wrapper for a project with it (and running into roadblocks along the way) – we decided to publish this.

    Here were the issues we discovered/filed related to this:

    We know that solutions like superagent exist, but they don't seem to work well with React Native (which was our use case for this package).

    In addition, the authors of WHATWG's fetch API only support throwing errors instead of catching them and bubbling them up to the callback/promise (for example, with Frisbee any HTTP or API errors are found in the res.err object).

    Therefore we created frisbee to serve as our API glue, and hopefully it'll serve as yours too.
