Integrating Passkey Authentication in a Solid.js and Hono(Bun) App

This repository demonstrates how to add passkey login functionality to your Solid.js and Bun with Hono app using the Hanko Passkey API. Passkey authentication is a secure and user-friendly alternative to traditional password-based authentication, providing a seamless login experience for users.

For a detailed tutorial on implementing passkey login in your Solid.js app, refer to our blog post: Passkeys in Solid.js and Bun

Prerequisites

Before you begin, ensure you have the following:

• Node.js installed (version 20.0.0 or later)
• Hanko Passkey API key and tenant ID from Hanko Cloud

Note: You'll need to create a Passkey Project on Hanko Cloud with the App URL http://localhost:5173. See our docs to learn how to setup a passkey project.

Getting started

1. Clone the repository

git clone https://github.com/teamhanko/passkeys-solid-hono

2. Set up environment variables

Create a .env file in the bun-hono-backend directory and add the following environment variables:

PASSKEYS_API_KEY=your-hanko-passkey-api-key
PASSKEYS_TENANT_ID=your-hanko-passkey-tenant-id

Replace your-hanko-passkey-api-key and your-hanko-passkey-tenant-id with your actual Hanko Passkey API key and tenant ID.

Frontend

1. Navigate to the frontend directory:

cd solid-frontend

2. Install the frontend dependencies using your preferred package manager (e.g., npm, pnpm, yarn, or bun). For this project, we've used bun:

bun install

3. Start the frontend development server:

bun dev

Backend

1. Navigate to the backend directory:

cd bun-hono-backend

2. Install the backend dependencies:

bun install

3. Start the backend server:

bun dev

Usage

1. Start the application:

   • Ensure that both the frontend and backend servers are running.

   • Access the application by navigating to http://localhost:5173 in your web browser.

2. Log in with a pre-configured user: Navigate to login page, login with one of the pre-configured users.

    {
        "id": "b3fbbdbd-6bb5-4558-9055-3b54a9469629",

        "email": "[email protected]",
        "password": "123",
    }
