Antonio

A HTTP client that uses axios for making all HTTP requests and @ackee/petrus for adding an access token to the Authorization header.

Table of contents


Installing

Using yarn:

$ yarn add @ackee/antonio

Using npm:

$ npm i -S @ackee/antonio

Initialization

1. Create new instance

import * as Antonio from '@ackee/antonio';
 
const defaultRequestConfig = {
    baseURL: 'https://base-url.com/api',
};
 
const { api, authApi, saga } = Antonio.create(defaultRequestConfig);
 
export { api, authApi, saga };

2. Connect the saga

Initializes the saga handlers generator. This should be passed along with your other sagas.

import { saga as antonio } from 'Config/antonio';
 
export default function*() {
    // antonio's saga must come before @ackee/petrus saga
    yield all([antonio()]);
}

Usage

api - unauthorized requests

See available properties of the api object.

import { api } from 'Config/antonio';
 
function* fetchTodo(todoId) {
    const response = yield api.get('/todos/:todoId', {
        // overwrite the default baseURL
        baseURL: 'https://jsonplaceholder.typicode.com/',
        uriParams: {
            todoId,
        },
    });
 
    return response.data;
}

authApi - authorized requests

By using methods under authApi object, it's guaranteed that each HTTP request is going to have an access token in its Authorization header.

If the access token isn't available at the moment, the request is paused by take(ACCESS_TOKEN_AVAILABLE) effect, and timeout, if enabled, is set. See the accessTokenUnavailableTimeout for more details.

See available properties of the authApi object.

import { authApi } from 'Config/antonio';
 
function* fetchPost(postId) {
    const response = yield authApi.get(`/posts/${postId}`);
 
    return response.data;
}

Shared defaults

Even though api and authApi are created as separated axios instances, they share the same default request config object - api.defaults and authApi.defaults. This issue/feature is caused by how axios is implemented and @ackee/antonio won't change it. Just don't be surprised, when you see the Authorization header also in requests created by the api.


API

create(defaultRequestConfig: Object, customConfig: Object) => Object

This method receives two objects as arguments.

  • defaultRequestConfig: Object

    The defaultRequestConfig object is passed to axios as default request configuration.

    Available properties:

    • axios request config
    • additional props:
      // `uriParams` - Key-value object containing request uri params. Params that are found in url are replaced, rest is ignored.
      uriParams: {
          // ':todoId' will be replaced with '1'
          // '/todos/:todoId' -> '/todos/1'
          todoId: '1',
      },
  • customConfig: Object

    The customConfig object offers following default options:

    {
        // If `manageAuthHeader` is true, then when access token state changes,
        // the `setAuthHeader` is triggered.
        // If it's false, `setAuthHeader` won't be ever triggered.
        manageAuthHeader: true,
     
        /**
         * If `manageAuthHeader` is enabled, `setAuthHeader` receives
         * object with default headers, when access token state changes.
         * @param {Object} headers - reference to axios default request headers object (https://github.com/axios/axios#custom-instance-defaults)
         * @param {Object|null} accessToken 
         */
        setAuthHeader(headers, accessToken) {
            if (accessToken) {
                // `common` indicates that it's a default header for all HTTP methods
                headers.common.Authorization = `Bearer ${accessToken.token}`;
            } else {
                delete headers.common.Authorization;
            }
        },
     
        // If it's used `authApi` and access token isn't available,
        // there is optionable timeout with following default values:
        accessTokenUnavailableTimeout: {
            // enable / disable the timeout
            enabled: false,
            // set timeout duration for 30s
            duration: 1000 * 30,
            // if silent is true, then throw a custom error,
            // othewise API request will be made that fails,
            // and throws a server error
            silent: false,
        },
    }

And returns:

  • Object

    #### api, authApi

    api and authApi have the same following properties:

    • api.request(config)
    • api.get(url[, config])
    • api.delete(url[, config])
    • api.head(url[, config])
    • api.options(url[, config])
    • api.post(url[, data[, config]])
    • api.put(url[, data[, config]])
    • api.patch(url[, data[, config]])
    • api.getUri([config])
    • api.defaults
    • api.interceptors

    #### saga

    Internal saga, primarily for communication with @ackee/petrus.

Example

import * as Antonio from '@ackee/antonio';
 
const { authApi } = Antonio.create(
    {
        baseURL: 'https://jsonplaceholder.typicode.com/',
    },
    {
        // Customize setting of the authorization header
        // by providing a custom setAuthHeader method:
        setAuthHeader(headers, accessToken) {
            if (accessToken) {
                headers.common.Authorization = `${accessToken.tokenType} ${accessToken.token}`;
            } else {
                delete headers.common.Authorization;
            }
        },
    },
);
 
async function fetchTodo() {
    const response = await authApi.get('/todos/1');
 
    return response.data;
}
