Penzle Core package
This package includes the core modules and utilities for the penzle-delivery.js
and penzle-management.js
SDKs.
Installation
To install the JavaScript Delivery SDK, you can either use npm
or take advantage of global CDNs like jsdelivr
.
npm
To install the SDK via npm
, run this command:
npm i @penzle/core-sdk --save
UMD Bundles
For UMD bundles, include the library using a script
tag on your HTML
page. The library will be accessible through the penzleDelivery
global variable.
UMD bundles can be found in the dist/bundles
folder.
dist/bundles/penzle-core.js
dist/bundles/penzle-core.min.js
CDN Options
Choose between two available CDN options for the Penzle JavaScript Delivery SDK: the standard UMD bundle and the minified UMD bundle.
Standard UMD Bundle (penzle-core.js)
Use the following link to include the standard UMD bundle:
https://cdn.jsdelivr.net/npm/@penzle/core-sdk@latest/dist/bundles/penzle-core.js
Minified UMD Bundle (penzle-core.min.js)
Use the following link to include the minified UMD bundle:
https://cdn.jsdelivr.net/npm/@penzle/core-sdk@latest/dist/bundles/penzle-core.min.js
HttpService: Handling HTTP Requests and Responses with Retry Policy
The HttpService
class is an implementation of the ApiService
interface that provides functionality for making HTTP requests and processing responses. It uses the Axios library to make the requests and can be configured with custom settings.
Methods
The HttpService
class has methods for making HTTP requests, including get
, post
, delete
, patch
, and put
. Each method accepts a corresponding HttpMethod
object (e.g., HttpGet
, HttpPost
) and an optional HttpSettings
object, which contains settings like headers, responseType, cancellationToken, and retryStrategy.
For each request, the getRetryPolicy
method is used to determine the retry strategy based on the provided settings or the default retry strategy.
The ResponseFactory.create
method is used to create a Response
object from the Axios response and the retry strategy configuration.
createCancellationToken
This method creates a new HttpCancellationToken
that can be used to cancel an ongoing HTTP request. It uses the Axios CancelToken
and Canceler
to manage cancellation.
getRetryPolicy
This method returns the retry policy based on the provided RetryStrategySettings
or the default retry strategy. The default strategy has a maximum of 5 retries and uses an exponential delay between retries.
Usage
To use the HttpService
, create an instance and pass the desired settings (if any) to the constructor. Then, call the appropriate method (e.g., get
, post
, delete
, patch
, put
) with the required HttpMethod
object and optional HttpSettings
object.
Debugging
Each response from this SDK is bundled with supplementary debug data. This data can be extremely useful for troubleshooting if you encounter any issues, or if you need to examine network-related properties such as response headers.
Consider the following code snippet as an example:
// 'deliveryResponse.response' holds the raw response data, headers, status, etc.
const rawResponseData = httpService.get<TResult>(method: HttpGet, settings?: HttpSettings<CancelToken>);
// To access response headers specifically, use 'rawResponse.headers'.
const responseHeaders = rawResponseData.rawResponse.headers;
Implementing Test HTTP Service
In certain cases, you might want to inject a testing service as an implementation of the ApiService
interface. This is particularly useful when you're writing tests and want to mock HTTP responses. Our library provides a configurable TestHttpService
for such purposes.
import { TestHttpService } from '@penzle/core-sdk';
const client = new /*(Delivery/Management)*/Client() {
// ...
httpService: new TestHttpService({
fakeResponseJson: json,
throwError: false
});
