I Built a Retry Library Because I Kept Losing Failed API Calls

说明与用途

smart-retry 自动重试 Axios/Fetch 请求，记录失败细节，便于后续分析或重放。

问题

Existing retry libraries only retry a function and throw on failure, leaving no record of the failed request, making debugging hard.

结果

The library provides automatic retries for network errors, timeouts, 429s, and 5xx responses, logs detailed failure information to disk, and exposes a manager to inspect and replay failed requests.

工作流

• 1. Install the library: npm install @aubaid/smart-retry
• 2. Create a retry-enabled client: const client = createAxiosRetry({maxRetries:5, delay:2000, backoff:'exponential'});
• 3. Make API calls through the client (e.g., await client.get('https://api.example.com/users')).
• 4. If retries exhaust, the library logs the failed request to a file.
• 5. Retrieve logged failures via client.getRetryManager().getFailedRequests() and view log file path with getLogFilePath().

Drop-in Axios and Fetch clients, not just a generic wrapper function

Automatic failure logging when a request exhausts all retries, it gets written to disk with its URL, method, headers, body, and error
