Set Up Studio for a SSR Project

Note: Studio is currently available as part of an Early Access Program and may not be accessible to all users. For more information or to request access, contact our support team.

This guide explains how to configure Studio in a Next.js Server-Side Rendering (SSR) application. You’ll learn how to install the SDKs, initialize the required clients, fetch composition data, and render it on the server.

Note: This document assumes you are building with Next.js. While many concepts are transferable, code examples and configurations are specific to Next.js SSR.

Before you begin, make sure you have:

• A Live Preview–enabled stack in Contentstack
• A Studio Project with at least one published composition

Studio requires two SDKs:

1. Studio React SDK

   This SDK provides the tools to fetch and render compositions from Studio.

   Run one of the following commands in your project directory:

   npm i @contentstack/studio-react

   Or

   yarn add @contentstack/studio-react

2. Contentstack Delivery SDK

   Studio uses this SDK internally to fetch your content from the CMS.

   npm i @contentstack/delivery-sdk

   Or

   yarn add @contentstack/delivery-sdk

These tokens allow your front-end to securely request published and preview content from Contentstack.

To create a Delivery and Preview token, log in to your Contentstack account and perform the following steps:

1. Go to your stack, navigate to the settings panel, and select Tokens.
2. Click Delivery Token to create a new token.

   Tip: If you are on the Management Tokens tab, you can press “Alt + O” (for Windows users) or “Option + O” (for Mac users) to navigate to the Delivery Tokens tab.

3. Enter a Name (required) and a Description (optional) for the Delivery Token.
4. In the Scope section, choose the Branches or Aliases you want to associate with this token.
5. Select the Publishing Environments for which you want to generate the Delivery Token.
6. Enable the Create Preview Token toggle to generate a Preview Token associated with this Delivery Token.
7. Click Generate Token.

A new token appears in both the Delivery Token and Preview Token fields. You can copy the tokens for later use in your SDK configuration.

Create a configuration file (e.g., src/studio.ts) to store your Studio setup.

// src/studio.ts
import contentstack from "@contentstack/delivery-sdk";

const stack = contentstack.stack({
  apiKey: "api_key",            // Replace with your API key
  deliveryToken: "delivery_token",  // Replace with your Delivery token
  environment: "environment",       // Your target environment (e.g., 'development')
  live_preview: {
    preview_token: "preview_token",  // Your Preview token
    enable: true,
  },
});

export { stack };

In the same studio.ts file, import and initialize the Studio SDK:

import { studioSdk } from "@contentstack/studio-react";
import { stack } from "./studio";

export const studioClient = studioSdk.init({
  stackSdk: stack,
});

This studioClient will be used to fetch composition data in your SSR page.

In SSR mode, Next.js doesn’t transfer these configurations to the client. We must use the fetchSpecOptions() method in getServerSideProps to:

• Pass search parameters (from Studio preview mode)
• Fetch the Studio Spec (layout, metadata, and content)
• Extract the style sheet for server rendering

Example: pages/index.tsx

import { studioClient } from "../studio";
import { GetServerSidePropsContext } from "next";
import { extractStyles } from "@contentstack/studio-react";

export async function getServerSideProps(context: GetServerSidePropsContext) {
  try {
    const { query: searchQuery } = context;

    // Fetch composition spec and SSR options
    const studioProps = await studioClient.fetchSpecOptions({
      searchQuery,
      compositionUid: "page", // Replace with your composition UID
    });

    // Extract styles for SSR
    const styleSheet = extractStyles(studioProps.spec);

    return {
      props: {
        studioProps,
        styleSheet,
      },
    };
  } catch (error) {
    console.error("Error fetching composition data", error);
    return { notFound: true };
  }
}

In SSR, you must handle styles manually and pass them into <Head> so they are rendered during the initial server response.

Use the StudioComponent to render the fetched spec. Pass studioProps and inject the extracted styles into the <Head> tag.

import {
  StudioComponent,
  StudioComponentSpecOptions,
} from "@contentstack/studio-react";
import Head from "next/head";

interface HomeProps {
  studioProps: StudioComponentSpecOptions;
  styleSheet: string;
}

export default function Home({ studioProps, styleSheet }: HomeProps) {
  return (
    <>
      {styleSheet && {styleSheet}}
      

Here’s how the full pages/index.tsx might look:

import {
  StudioComponent,
  extractStyles,
  StudioComponentSpecOptions,
} from "@contentstack/studio-react";
import Head from "next/head";
import { studioClient } from "../studio";
import { GetServerSidePropsContext } from "next";

interface HomeProps {
  studioProps: StudioComponentSpecOptions;
  styleSheet: string;
}

export default function Home({ studioProps, styleSheet }: HomeProps) {
  return (
    <>
      {styleSheet && {styleSheet}}
      

You’ve integrated Studio into your Next.js SSR workflow, enabling server-rendered compositions with correct styles and data delivered at request time. This setup ensures fast initial page loads, SEO-friendly output, and compatibility with Live Preview and Visual Builder.

With your foundation in place, you can now focus on customizing components, binding dynamic content, and enhancing the end-user experience without reworking your rendering pipeline.
