# or
pnpm add @finsel-dgi/pasby-next

Requirements

• Next.js 13.4 or higher
• React 18 or higher
• Node.js 16 or higher

Environment Setup

Create a .env.local file in your project root and add the following variables:

PASBY_CLIENT_SECRET=<App secret>
PASBY_CONSUMER_KEY=<organisations api key>
PASBY_CLIENT_ID=<App id>
PASBY_LOGIN_REDIRECT=<fallback path after authentication e.g /dashboard>
PASBY_LOGOUT_REDIRECT=<fallback path after logout e.g /login>
SECRET_GEN=<generated random 16 string>

Quick Start

1. Setup API Route

Create a new API route at app/api/eid/[auth]/route.ts:

import { handler } from "@finsel-dgi/pasby-next/server";
import { cookies } from "next/headers";

export const GET = handler({
  claims: ["naming.given", "naming.family", "contact.email"], // Add required claims
  action: 'signup', // login | signup | link
  payload: "User registration request" // describe action intent
}, (key, value, exp) => {
  cookies().set(key, value, { 
    secure: true, 
    sameSite: true, 
    maxAge: (exp) 
  });
}, async (key) => {
  return cookies().get(key)?.value;
});

2. Add Authentication Button

In your client component:

"use client"

import { LoginButton } from "@finsel-dgi/pasby-next";

export function AuthComponent() {
  return (
    <LoginButton 
      variant="dark" 
      action="identify"
      fallbackPath="/dashboard"
    />
  );
}

Available button variants:

• original - Red background with white text
• dark - Dark background with white text
• light - White background with red text
• darktext - White background with black text

3. Access User Data

In your server component:

import { getEID } from "@finsel-dgi/pasby-next/server";
import { cookies } from "next/headers";

export async function UserProfile() {
  const cookieStore = cookies();
  const eid = await getEID(cookieStore);

  if (!eid) {
    return <div>Not authenticated</div>;
  }

  return (
    <div>
      <h1>Welcome, {eid.claims.contact.email}</h1>
      {/* Access other user data as needed */}
    </div>
  );
}

User Data Structure

The getEID function returns a user object with the following structure:

interface User {
  national: string;
  country: string;
  claims: {
    contact: {
      email: string;
      phone: string;
      emailVerified: boolean;
      phoneVerified: boolean;
    };
    address: {
      country: string;
      city: string;
      countryCode: string;
      formatted: string;
      postCode: string;
      place: string;
    };
    bio: {
      birthdate: string;
      gender: string;
      birthplace: string;
      birthnumber: number;
      maritalStatus: string;
      age: number;
    };
    nationality: {
      pep: boolean;
      nationalities: string[];
      residence: string;
      primary: string;
    };
  };
}

End user session

Simply have a button that makes a router push to /api/eid/logout. Before doing so ensure you have provided a fallback logout path at your env as PASBY_LOGOUT_REDIRECT
