When developing a website or web app, nobody wants to spend hours of their time just on speed optimization. The problem is that a fast website is incredibly important and performance is often a deciding factor for its success. Web frameworks like Remix Run were created with the goal of optimizing web performance while keeping their configuration to a minimum ("zero-config"). Nowadays, there are dozens of frameworks available, that help you achieve high speeds.

Unfortunately, the best website load times are of little use to us unless the databases of our apps are lightning fast as well.

Today, we are announcing @upstash/redis v1.0.0.

@upstash/redis is the only connectionless (HTTP based) Redis client that is designed for serverless and compatible with Cloudflare Workers and fastly.

In this blog post, we will implement a waiting room page for your website.

Why?​

High number of visitors on your website is a good thing generally but not always. Sudden high traffic may easily overwhelm your applications which may disrupt your services completely. Waiting room is a solution that helps you to control the traffic and protect your resources during traffic surges. Cloudflare Waiting Room is a good solution but it is only available for business and enterprise accounts. Don’t worry, in this blog we will build a waiting room for any type of web site using Cloudflare Workers and Upstash Redis.

It is a common need to restrict access to your website to some specific IPs. In this post, I will show how to implement an IP Allow/Deny list using Edge computing. Let me first introduce Cloudflare Workers.

Cloudflare Workers​

Cloudflare workers are quite popular technology in recent years. It became publicly available in 2017 and Cloudflare KV storage became publicly available in 2019.

Computing at the Edge is one of the most exciting capabilities in recent years. CDN allows you to keep your files closer to your users. Edge computing allows you to run your applications closer to your users. This helps developers to build globally distributed, performant applications.

Cloudflare Workers is the leading product in this space right now. It gives you a serverless processing environment without cold starts. You leverage Cloudflare's global network to minimize latency of your applications. You can write your functions in Javascript, Rust, C and C++.

Similar to Serverless functions (AWS Lambda etc.), Cloudflare Workers are stateless. As you can see in Cloudflare’s survey, developers are asking ways to connect their databases from Edge functions. Unfortunately, most databases are not designed for serverless environments, they require persistent connections. We developed the REST API over Redis to enable serverless edge functions to access Upstash in the simplest and fastest way possible.
