Code Examples
Retry with Exponential Backoff (Code Node)
javascript
// Implement custom retry logic
const maxRetries = 3;
const baseDelay = 1000; // 1 second
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
// Your API call here
const response = await $http.request({
method: "GET",
url: "https://api.example.com/data"
});
return [{ json: response }];
} catch (error) {
if (attempt === maxRetries) throw error;
const delay = baseDelay * Math.pow(2, attempt - 1);
await new Promise(r => setTimeout(r, delay));
}
}Pro Tips
- 💡Use the built-in "Retry On Fail" option on nodes before writing custom retry logic
