wrap-redis.ts

async function wrapRedis<T>(key: string, fn: () => Promise<T>, seconds = 60): Promise<T> {
	const cached = await redis.get(key);
	if (cached) return JSON.parse(cached);

	const recent = await fn();

	if (recent) {
		await redis.set(key, JSON.stringify(recent), 'ex', seconds);
	}

	return recent;
}

// Usage

app.get('/users/:id', async (req, res) => {
	const user = await wrapRedis(`user:${req.params.id}`, () => {
		return prisma.user.findFirst({
			where: {id: req.params.id},
		});
	});

	const {password, ...rest} = user;

	res.json(rest);
});

lol thanks for the code!
