Stytch

Last updated Apr 21, 2026 The Stytch Pages Plugin is a middleware which validates all requests and their session_token.

Installation

npmyarnpnpmbun

npm i @cloudflare/pages-plugin-stytch

yarn add @cloudflare/pages-plugin-stytch

pnpm add @cloudflare/pages-plugin-stytch

bun add @cloudflare/pages-plugin-stytch

Usage

import stytchPlugin from "@cloudflare/pages-plugin-stytch";
import { envs } from "@cloudflare/pages-plugin-stytch/api";

export const onRequest: PagesFunction = stytchPlugin({
    project_id: "YOUR_STYTCH_PROJECT_ID",
    secret: "YOUR_STYTCH_PROJECT_SECRET",
    env: envs.live,
});

We recommend storing your secret in KV rather than in plain text as above.

The Stytch Plugin takes a single argument, an object with several properties. project_id and secret are mandatory strings and can be found in Stytch's dashboard ↗︎. env is also a mandatory string, and can be populated with the envs.test or envs.live variables in the API. By default, the Plugin validates a session_token cookie of the incoming request, but you can also optionally pass in a session_token or session_jwt string yourself if you are using some other mechanism to identify user sessions. Finally, you can also pass in a session_duration_minutes in order to extend the lifetime of the session. More information on these parameters can be found in Stytch's documentation ↗︎.

The validated session response containing user information is made available to subsequent Pages Functions on data.stytch.session.
