A Valkey (Redis) cache for your Next.js app

Create a Valkey server for caching in this Next.js app on Rowsafe Cloud.

Your agent picks a size, tells you the price and waits for your yes, then creates the server as you. Once it's ready (5 to 10 minutes), click Create a login for your app on its page in the dashboard: you see the connection details once, for your .env.

First time? Connect Rowsafe to your agent once.

rowsafe cloud create app-cache --engine valkey --wait
rowsafe db user add web --on app-cache

rowsafe cloud create shows the price and asks first. rowsafe db user add makes a login for your app and prints its rediss:// connection string once: put it in .env as REDIS_URL. (rowsafe env is for PostgreSQL only, for now.)

import { createClient } from "redis";

// REDIS_URL starts with rediss://: encrypted, and the server's certificate is checked.
const client = createClient({ url: process.env.REDIS_URL });
client.on("error", (err) => console.error("Valkey:", err));
const ready = client.connect();

export async function cached<T>(key: string, seconds: number, load: () => Promise<T>): Promise<T> {
  await ready;
  const hit = await client.get(key);
  if (hit) return JSON.parse(hit) as T;
  const value = await load();
  await client.set(key, JSON.stringify(value), { expiration: { type: "EX", value: seconds } });
  return value;
}

npm install redis. ioredis works too: give it the same rediss:// URL. Valkey takes connections with TLS on port 6380 only.

Rowsafe backs up every change, encrypted on the server with a key only you have, so you can restore to any second. Every week it restores a backup to prove it works. Restore a copy, bring back deleted keys or rewind the whole database, in one click. Before a risky change, save a Mark (rowsafe mark), or let your agent save one.

From $0.014 an hour, never more than $10 a month.
