Downstream started rate-limiting your Node BFF? Here's the retry layer that fixes it.

Your Node BFF proxies to a downstream API — a payment provider, a recommendations service, a partner's data feed. One Tuesday the partner starts returning 429 and the occasional 503. Suddenly your users see errors, and the partner's status page lists you as their top traffic source. Something has to change on your side.

Here's the outbound call most BFFs start with:

import express from 'express';

import axios from 'axios';

const app = express();
