The Dark Side of Open Source
At Node Congress, Socket CEO Feross Aboukhadijeh uncovers the darker aspects of open source, where applications that rely heavily on third-party dependencies can be exploited in supply chain attacks.
httplease-retry
Advanced tools
Readme
Provides two different retry mechanisms, backoff and failover retrying as an httplease filter.
Failover retry filter retries requests with optional fallback to alternate servers. Backoff retry filter will retry against the same server until the retryTimeout limit has been reached. By default it will retry if 429s and 503s are received, but this logic can be changed by specifying 'shouldRetryFn'.
Install the library:
npm install --save httplease-retry
For more examples have a look at the test/integration
directory.
const httplease = require('httplease');
const httpleaseRetry = require('httplease-retry');
const retryConfig = {
shouldRetryFn: ({
error, // The error from httplease
attempts, // Number of attempts
requestConfig, // httplease requestConfig
}) => true,
maxAttempts: 2,
retryDelayMillis: 50,
baseUrlList: [
'http://example.com/basePath',
'http://example.com/secondaryPath
]
};
// this can be saved and reused as many times as you want
const httpClient = httplease.builder()
.withFilter(httpleaseRetry.createFailoverRetryFilter(retryConfig));
// make a request
httpClient
.withPath('/some-resource')
.withMethodGet()
.send();
const httplease = require('httplease');
const httpleaseRetry = require('httplease-retry');
const retryConfig = {
retryTimeoutMillis: 10 * 1000 //Retries for a maximum of 10 seconds after the Request started
shouldRetryFn: ({
error, // The error from httplease
attempts, // Number of attempts
requestConfig, // httplease requestConfig
startTimestamp // The timestamp the when the request started
}) = attempts > 5 // Example to stop retrying after 5 attempts
};
// this can be saved and reused as many times as you want
const httpClient = httplease.builder()
.withFilter(httpleaseRetry.createBackoffRetryFilter(retryConfig));
// make a request
httpClient
.withPath('/some-resource')
.withMethodGet()
.send();
