Simple wrapper around fetch function to manage in a simple way the errors from BE using http status code

Usage

1. Installation

fd-fetch-wrapper

2. Import

import { FetchWrapper } from 'fd-fetch-wrapper';

3. Create an instance of FetchWrapper

 const runner = new FetchWrapper(apiVersion, labels, status_401_403);

Where

• apiVersion: optional parameter that can be used when we have different api version on our server, a parameter named 'api-version' will be added to the header

• labels: optional parameter used to let you choose the message to show at FE for common error

static labels = {
   errorGeneric: 'Sorry we have errors on the remote server',
   errorServerNotAvailable: 'Server not available',
   errorSessionExpired: 'Your session has expired, please login.',
};

• status_401_403: this is a callback function with no parameters that can be used to let you logout the user

4. Avaliable methods

delete = (url, params, token, isFile = false, isBlob = false)

get = (url, token, params, isFile = false, isBlob = false) 

post = (url, params, token, isFile = false, isBlob = false, additionalParams = [])

put = (url, params, token, isFile = false, isBlob = false)

Sample

You can find this code in github, App.js of this repository

function App() {

    function status_401_403() {
        alert("Log Out");
    }

    const runner = new FetchWrapper(null, null, status_401_403);

    function onClick() {
        runner.get('http://localhost:61419/weatherforecast').then(response => {
            alert(response);
        }).catch(errorMessage => {
            if (errorMessage)
                alert(errorMessage);
