Fetch Retries and Backoff Matrix

Timeouts, jitter, and circuit breaker hints.

Reference Web
const withRetry = async (fn, { tries = 3, base = 250 } = {}) => {
  let error;
  for (let i = 0; i < tries; i++) {
    try { return await fn(); }
    catch (e) {
      error = e;
      const jitter = Math.random() * 100;
      await new Promise(r => setTimeout(r, base * 2 ** i + jitter));
    }
  }
  throw error;
};

ETag vs. Last-Modified Decision Tree

How to pick validators and control revalidation.

Reference Performance
# Pseudocode
if content_is_static and build_hash_available:
  use ETag (strong)
elif content_is_time_driven:
  use Last-Modified with second precision
else:
  ETag (weak) + Cache-Control: max-age=0, must-revalidate

Abortable Fetch With Timeout

const fetchWithTimeout = (url, ms=5000) => {
  const ctrl = new AbortController();
  const id = setTimeout(() => ctrl.abort(), ms);
  return fetch(url, { signal: ctrl.signal }).finally(() => clearTimeout(id));
};

Minimal Healthcheck Server

import http from 'node:http';
http.createServer((req, res) => {
  if (req.url === '/health') { res.writeHead(200); res.end('ok'); return; }
  res.writeHead(404); res.end();
}).listen(8787);
