Edge Redirects with Upstash

This demo features a list of redirects, both hardcoded and coming from Redis (Upstash), that get evaluated at the edge.

The demo has a total of 10,000 redirects, 1,000 of which are hardcoded on a JSON file, and 9,000 added to Redis.

Redirects in a JSON file are faster to evaluate, but they can only be edited at build time, with Redis we can have editable redirects with a low latency cost.

How to Use

You can choose from one of the following two methods to use this repository:

One-Click Deploy

Deploy the example using Vercel:

Clone and Deploy

Execute create-next-app with npm or Yarn to bootstrap the example:

pnpm create next-app --example https://github.com/vercel/examples/tree/main/edge-middleware/redirects-upstash redirects-upstash

You'll need to have an account with Upstash. Once that's done, copy the .env.example file in this directory to .env.local (which will be ignored by Git):

cp .env.example .env.local

Then open .env.local and set the environment variables to match the REST API and Edge API of your database. It should look like this:

# Upstash REST API
UPSTASH_REST_API_DOMAIN = "us1-shiny-firefly-12345.upstash.io"
UPSTASH_REST_API_TOKEN = "your-api-token"

We populate the redirects in Upstash in scripts/upstash.js using their REST API, if you prefer not to do that then set POPULATE_REDIS to false in .env. JSON redirects are also created there.

Next, run Next.js in development mode:

pnpm dev

Deploy it to the cloud with Vercel (Documentation).
