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 pnpm to bootstrap the example:

pnpm create next-app --example https://github.com/vercel/examples/tree/main/edge-functions/api-rate-limit-and-tokens api-rate-limit-and-tokens

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"
API_KEYS_JWT_SECRET_KEY = "a-secret-key"

Next, run Next.js in development mode:

pnpm dev

Deploy it to the cloud with Vercel (Documentation).
