​
Prerequisites

Install the Corbado Node.js SDK:

npm install @corbado/node-sdk

Generate an API secret in the developer panel to allow the SDK to access the Corbado Backend API.

​
Example

To gain access to authentication state on the server-side we utilize the Corbdo Node.js SDK.

We might use it in a server-side action function to verify the user is authenticated and retrieve some data in this case:

actions.ts
"use server";

import { redirect } from "next/navigation";
import { cookies } from "next/headers";
import { Config, SDK } from '@corbado/node-sdk';

const config = new Config(
    process.env.PUBLIC_CORBADO_PROJECT_ID, process.env.CORBADO_API_SECRET,
    `https://${process.env.PUBLIC_CORBADO_PROJECT_ID}.frontendapi.corbado.io`,
    'https://backendapi.cloud.corbado.io'
);
const sdk = new SDK(config);

export async function getUser() {
    const sessionToken = cookies().get('cbo_session_token')?.value;
    if (!sessionToken) {
        redirect("/")
    }

    try {
        const user = await sdk.sessions().validateToken(sessionToken);
        return { user: { name: user.fullName, userID: user.userId } };
    } catch (e) {
        // session cookie was invalid
        redirect("/")
    }
}
