API Rate Limiting with Upstash

This example features API Rate limiting at the edge with Redis using Upstash.

The pattern for rate limiting is inspired by the GitHub API.

One-Click Deploy

Deploy the example using Vercel:

Getting Started

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

npx create-next-app --example https://github.com/vercel/examples/tree/main/edge-functions/api-rate-limit api-rate-limit
# or
yarn create next-app --example https://github.com/vercel/examples/tree/main/edge-functions/api-rate-limit api-rate-limit

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 of your database. It should look like this:

UPSTASH_REST_API_DOMAIN = "us1-shiny-firefly-12345.upstash.io"
UPSTASH_REST_API_TOKEN = "your-api-token"

Next, run Next.js in development mode:

npm install
npm run dev

# or

yarn
yarn dev

Deploy it to the cloud with Vercel (Documentation).
