Readme

@paysera/http-client-common

Axios requests wrapper.
Basically we use this library in our generated JS clients from RAML.

Installation

npm i @paysera/http-client-common

Include files:

<script type="text/javascript" src="dist/main.js"></script>

Dependencies

Usage

Without any middleware

import { createClient, createRequest } from '@paysera/http-client-common';

const client = createClient({
    baseURL: 'https://demo.com',
});

client.performRequest(createRequest('get', '/list'));

With JWT authentication middleware(with session storage token provider)

In this example client.performRequest makes request with Authorization: 'Bearer {accessToken}' header

import { 
    createClient, 
    createRequest,
    JWTAuthenticationMiddleware,
    SessionStorageTokenProvider,
    Scope,
} from '@paysera/http-client-common';

const client = createClient({
    baseURL: 'https://{shard_id}.demo.com/{locale}', // base url with parameters
    middleware: [
        new JWTAuthenticationMiddleware(
            new Scope('scope:a'),
            new SessionStorageTokenProvider(
                (scope) => ({ scope, accessToken: 'created-token' }), 
                (scope) => ({ scope, accessToken: 'refreshed-token' }),
                'unique',
                'namespace',   
            ),
        ),
    ],
    options: {
        urlParameters: {
            // list of url parameters
        }
    }
});

client.performRequest(createRequest('get', '/list'));

Write your own middleware

class MyCustomMiddleware {
    async onRequest(config) {
        // here you can make some changes to config object
        return config;
    }
        
    async onResponseError(error) {
        // here you can make some changes to error response
        return error;
    }
}

Under the hood middleware use axios interceptors, so basically middleware is wrapper for axios interceptors. More about axios interceptors you can read here

  • onRequest(config) - will be called every time before making request.
  • onResponseError(error) - will be called every time after request returns error
