Overview

Clerk is the easiest way to add authentication and user management to your Gatsby application. Add sign up, sign in, and profile management to your application in minutes.

Getting Started

Prerequisites

• Gatsby v5+
• Node.js v18+

Installation

npm install gatsby-plugin-clerk

Usage

Make sure the following environment variables are set in a .env file:

GATSBY_CLERK_PUBLISHABLE_KEY=your_publishable_key
CLERK_SECRET_KEY=your_secret_key

You can get these from the API Keys screen in your Clerk dashboard.

To initialize Clerk with your Gatsby application, simply register the plugin in your gatsby-config.ts/gatsby-config.js file. Also, use dotenv to access environment variables.

// gatsby-config.ts
import type { GatsbyConfig } from 'gatsby';

require('dotenv').config({
  path: `.env.${process.env.NODE_ENV}`,
});

const config: GatsbyConfig = {
  // ...the rest of your config object
  plugins: ['gatsby-plugin-clerk'],
};

export default config;

Client-side

After those changes are made, you can use Clerk components in your pages.

For example, in src/pages/index.tsx:

import { SignedIn, SignedOut, SignInButton, UserButton } from 'gatsby-plugin-clerk';

const IndexPage = () => {
  return (
    <div>
      <h1>Hello Clerk!</h1>
      <SignedIn>
        <UserButton />
      </SignedIn>
      <SignedOut>
        <SignInButton mode='modal' />
      </SignedOut>
    </div>
  );
};

export default IndexPage;

Server-Side Rendering (SSR)

Using withServerAuth from 'gatsby-plugin-clerk/ssr'. Example file /pages/ssr.tsx:

import * as React from 'react';
import { GetServerData } from 'gatsby';
import { withServerAuth } from 'gatsby-plugin-clerk/ssr';

export const getServerData: GetServerData<any> = withServerAuth(
  async props => {
    return { props: { data: '1', auth: props.auth } };
  },
  { loadUser: true },
);

function SSRPage({ serverData }: any) {
  return (
    <main>
      <h1>SSR Page with Clerk</h1>
      <pre>{JSON.stringify(serverData, null, 2)}</pre>
    </main>
  );
}

export default SSRPage;

Server API routes

Importing 'gatsby-plugin-clerk/api' gives access to all the exports coming from @clerk/sdk-node. Example file /api/hello.ts:

import { clerkClient, withAuth } from 'gatsby-plugin-clerk/api';

const handler = withAuth(async (req, res) => {
  const users = await clerkClient.users.getUserList();
  res.send({ title: `We have ${users.length} users`, auth: req.auth });
});

export default handler;
