pages-plugin-verify-jwt

pages-plugin-verify-jwt is a Cloudflare Pages plugin used by the fundamend.dev ecosystem. It offers a middleware for verifying JWTs with a verification key.

Installation

Use your favorite Node.js package manager, for example npm, like so:

npm install --save @fundamend/pages-plugin-verify-jwt

... or yarn, like so:

yarn add @fundamend/pages-plugin-verify-jwt

Usage

Add a _middleware.js file where you want to verify JWTs, import pages-plugin-verify-jwt and call it on a request, like so:

import verifyJWTPlugin from "@fundamend/pages-plugin-verify-jwt";

export const onRequest = verifyJWTPlugin();

The plugin expects an environment variable of the name JWT_VERIFICATION_KEY to be set in Cloudflare. Create this variable in the Cloudflare Dashboard or with wrangler (for local testing use a .dev.vars file) and set it to the verification key of your JWT token.

The plugin will be executed on every request inside the _middleware.js file's path. If the JWT verifies with the JWT_VERIFICATION_KEY, it calls the next Cloudflare Pages function or middleware. If not, it returns a 401 - Unauthorized response.
