library1.0.0jsnpmunverified

The `retry-promise` package (version 1.0.0), last published in November 2015, provides a small utility function for automatically retrying promise-returning operations. It was explicitly designed to work with Bluebird Promises and implements a basic retry mechanism with configurable maximum attempts (`opts.max`) and a linear backoff strategy. The delay between retries is calculated as `attempt_number * opts.backoff`, meaning each subsequent retry waits proportionally longer. Given its age and lack of updates for nearly a decade, this package is considered abandoned. It lacks support for modern JavaScript features like native Promises or ES Modules and does not offer advanced retry strategies (e.g., jitter, custom error predicates) found in more actively maintained alternatives such as `p-retry` or `ts-retry-promise`. For new projects, developers should consider these contemporary libraries over `retry-promise`.

retry
✓ const retry = require('retry-promise');
This package is CommonJS-only and relies on `require()`.

This quickstart demonstrates how to use `retry-promise` to retry a function that returns a Promise until it resolves. It includes a mock `User` service that simulates transient failures, showcasing the retry logic and linear backoff strategy.

const retry = require('retry-promise'); // Mock a User model that occasionally fails to demonstrate retries let creationAttempts = 0; const User = { forge: function(data) { return { createOrLoad: function() { return new Promise((resolve, reject) => { creationAttempts++; console.log(`[Mock User] Attempt ${creationAttempts} to create user ${data.email}`); if (creationAttempts < 3) { // Simulate transient failure for the first 2 attempts console.log(`[Mock User] Failed attempt ${creationAttempts}`); return reject(new Error('Database temporarily unavailable')); } else { console.log(`[Mock User] Succeeded on attempt ${creationAttempts}`); return resolve({ id: 1, email: data.email }); } }); } }; } }; // Mock Express-like req/next for a runnable example const req = {}; const next = (err) => { if (err) { console.error('Middleware error:', err.message); } else { console.log('Middleware successful. User:', req.user); } }; console.log('Starting retry operation...'); retry({ max: 3, backoff: 1000 }, function (attempt) { console.log(`retry-promise callback - Attempt ${attempt}`); return User .forge({ email: 'test@example.com' }) .createOrLoad(); }) .then(function (user) { req.user = user; next(); }) .catch(function(error) { console.error('[retry-promise] Final failure:', error.message); next(error); });
Debug
Known issues
breakingThe `retry-promise` package is effectively abandoned, with its last update occurring approximately ten years ago. It is unlikely to receive further maintenance, bug fixes, or compatibility updates for modern JavaScript environments, native Promises, or ES Modules.
fix
Consider migrating to actively maintained alternatives like `p-retry` or `ts-retry-promise` for modern applications.
affects: >=1.0.0
gotchaThe package explicitly targets 'bluebird Promises' but does not declare `bluebird` as a dependency. Using native JavaScript Promises or other Promise libraries directly might lead to unexpected behavior or errors if their implementations are not fully compatible with `retry-promise`'s internal workings.
fix
Ensure `bluebird` is installed and used if encountering unexpected Promise-related issues, or use a modern retry library that supports native Promises by default.
affects: >=1.0.0
gotchaThe backoff strategy is linear, calculating the delay as `attempt_number * opts.backoff`. This differs from exponential backoff strategies commonly found in modern retry libraries, which typically increase delays more aggressively to mitigate overloaded services.
fix
Be aware of the linear backoff behavior. If exponential backoff or more sophisticated strategies (e.g., jitter, custom predicates for retrying specific errors) are required, consider alternative retry libraries.
affects: >=1.0.0
Errors
Common errors & fixes
TypeError: (intermediate value) is not a function
This typically occurs when `retry-promise` expects a Bluebird Promise instance, but it receives a non-callable value, possibly due to direct use of native Promises or an incompatible Promise implementation.
fix
Ensure that Bluebird is being used or that the function passed to `retry` explicitly returns a Bluebird Promise. If migrating is not an option, you might need to manually adapt Bluebird into your project.
TypeError: Cannot read properties of undefined (reading 'then')
The function provided to `retry` did not return a Promise or a 'thenable' object, causing `retry-promise` to fail when attempting to chain operations.
fix
Modify the function passed to `retry` to ensure it always returns a Promise, regardless of its execution path.
