supabase-auth-helpers-astro

supabase-auth-helpers-astro is an NPM package that provides authentication utility functions for integrating Supabase authentication seamlessly into Astro framework applications. Most of the code was orginated from Supabase Auth Helpers / NextJS

Features

• Create Supabase client instances for different scenarios within the Astro framework.
• Simplify authentication and authorization workflows with Supabase.
• Reusable functions for client-side components, server-side components, and server-side route rendering.

Installation

This library supports the following tooling versions:

• Node.js: ^16.15.0

To install the package, you can use pnpm:

pnpm install supabase-auth-helpers-astro

To install the package, you can use npm:

npm install supabase-auth-helpers-astro

Or with yarn:

yarn add supabase-auth-helpers-astro

Usage

First define environment variables:

# Find these in your Supabase project settings > API
# Client Side
PUBLIC_SUPABASE_URL=https://your-project.supabase.co
PUBLIC_SUPABASE_ANON_KEY=your-anon-key
# Server Side
SUPABASE_URL=https://your-project.supabase.co
SUPABASE_ANON_KEY=your-anon-key

If needed added server side rendering

// astro.config.mjs
import { defineConfig } from "astro/config";

// https://astro.build/config
export default defineConfig({
  output: "server",
});

Here's an example of how you can use the package in your Astro application:

import { AstroCookies } from "astro";
import {
  createClientComponentClient,
  createServerComponentClient,
  createServerRouteClient,
  createServerMiddlewareClient
} from "supabase-auth-helpers-astro";

// Example usage of createClientComponentClient
export const clientComponentClient = () =>
  createClientComponentClient({
    supabaseUrl: import.meta.env.PUBLIC_SUPABASE_URL,
    supabaseKey: import.meta.env.PUBLIC_SUPABASE_ANON_KEY,
  });


// Example usage of createServerComponentClient could also be on routes
export const serverComponentClient = (cookies: AstroCookies) =>
  createServerComponentClient(
    {
      cookies,
    },
    {
      supabaseUrl: import.meta.env.SUPABASE_URL,
      supabaseKey: import.meta.env.SUPABASE_ANON_KEY,
    },
  );

// Example usage of createServerRouteClient I recommed to use (createServerComponentClient)
export const serverRouteClient = (cookies: AstroCookies) =>
  createServerRouteClient(
    {
      cookies,
    },
    {
      supabaseUrl: import.meta.env.SUPABASE_URL,
      supabaseKey: import.meta.env.SUPABASE_ANON_KEY,
    },
  );

// Example usage of createServerMiddlewareClient could also be on routes
export const serverMiddlewareClient = (req: Request, res: Response) =>
  createServerMiddlewareClient(
    {
      request: req,
      response: res,
    },
    {
      supabaseUrl: import.meta.env.SUPABASE_URL,
      supabaseKey: import.meta.env.SUPABASE_ANON_KEY,
    },
  );

Whoever uses SSR needs to have a middleware to refresh the tokens at src/middleware.ts:

import { defineMiddleware } from "astro:middleware";

// `context` and `next` are automatically typed
export const onRequest = defineMiddleware(async (context, next) => {
  const res = await next();
  const supabase = createServerMiddlewareClient(
    {
      request: req,
      response: res,
    },
    {
      supabaseUrl: import.meta.env.SUPABASE_URL,
      supabaseKey: import.meta.env.SUPABASE_ANON_KEY,
    },
  );
  await supabase.auth.getSession();
  return res;
});
