Adobe I/O Core Networking Lib

Installing

$ npm install @adobe/aio-lib-core-networking

Usage

1. Initialize the SDK

const fetchRetry = require('@adobe/aio-lib-core-networking')

2. Call methods using the initialized SDK

const fetchRetry = require('@adobe/aio-lib-core-networking')
async function sdkTest() {

  return new Promise((resolve, reject) => {
    fetchRetry.exponentialBackoff(url, requestOptions, retryOptions, retryOn, retryDelay)
    .then((response) => {
      if (!response.ok) {
        throw Error(reduceError(response))
      }
      resolve(response.json())
    })
    .catch(err => {
      reject(
        new codes.ERROR_GET_SOMETHING({ sdkDetails, messageValues: err }))
    })
  }) 
}

Working of HttpExponentialBackoff

@adobe/aio-lib-core-networking~HttpExponentialBackoff

This class provides methods to implement fetch with retries. The retries use exponential backoff strategy with defaults set to max of 3 retries and initial Delay as 100ms

Kind: inner class of @adobe/aio-lib-core-networking

httpExponentialBackoff.exponentialBackoff(url, requestOptions, retryOptions, retryOn, retryDelay) ⇒ Promise.<Response>

This function will retry connecting to a url end-point, with exponential backoff. Returns a Promise.

Kind: instance method of HttpExponentialBackoff
Returns: Promise.<Response> - Promise object representing the http response

Param	Type	Description
url	string	endpoint url
requestOptions	object	request options which includes the HTTP method, headers, timeout, etc.
retryOptions	object	retry options with options being maxRetries and initialDelayInMillis
retryOn	function | Array	Optional Function or Array. If provided, will be used instead of the default
retryDelay	function | number	Optional Function or number. If provided, will be used instead of the default

Debug Logs

LOG_LEVEL=debug <your_call_here>

Prepend the LOG_LEVEL environment variable and debug value to the call that invokes your function, on the command line. This should output a lot of debug data for your SDK calls.
