In today's fast-paced digital landscape, the ability to provide dynamic content previews is a game-changer for web developers and content creators. Integrating Kontent.ai with Next.js opens up a world of possibilities for real-time content updates and previews. 

Join Kapsys as we explore the dynamic content previews, preview settings, and what they mean for your Next.js project.


The Power of Dynamic Content Preview

Before we delve into the technical aspects, let's understand what dynamic content preview means and why it's essential for modern web development. 

Dynamic content preview allows you to see how your content will appear in real time, ensuring that it aligns with your vision and meets the requirements of your audience.

Imagine seeing how a new blog post, product listing, or landing page looks and functions before hitting that "publish" button. 

With dynamic content preview, you can identify issues, make necessary adjustments, and provide a seamless user experience. This not only saves time but also reduces the risk of errors and inconsistencies in your web content.

Introducing Kontent.ai and Next.js

Kontent.ai is a powerful headless content management system (CMS) that offers various features, including dynamic content preview,  for managing and delivering content. 

On the other hand, Next.js is a popular React framework that enables server-side rendering, routing, and other performance optimizations. 

Together, they form a dynamic duo for creating modern, interactive websites with real-time content updates.

Dynamic Content Previews with Kontent.ai and Next.js

Now that you have Kontent.ai and Next.js working together, it's time to implement dynamic content previews. Here's how to do it:

Preview settings

Kontent.ai offers powerful preview settings that allow you to see how your content will look before it's published. Here's how you can do that:

  • Access the Kontent.ai dashboard and navigate to your project.

  • Locate the "Preview Settings" section or similar in your project's settings.

  • Configure preview settings to match your requirements. This may include specifying preview domains, enabling real-time preview, and defining the default preview content.

  • Save your changes.


Set up webhooks in your Kontent.ai project to trigger updates in your Next.js application whenever content changes are made in the CMS. Let's break this down:

  • In your Kontent.ai project settings, find the "Webhooks" section.

  • Create a new webhook or configure an existing one.

  • Set the webhook URL to your Next.js application endpoint, where you want to receive content updates.

  • Define the events that should trigger the webhook, such as "Content Item Changes."

  • Save the webhook settings.

Preview content types

Define specific content types that you want to preview. For example, if you're working on a blog, you can enable preview for blog posts, images, and related content:

  • In your Kontent.ai project, navigate to the content types settings.

  • For each selected content type, ensure that the "Enable Preview" or similar option is enabled.

  • Save your content type settings.

Custom preview URLs

Customize the URLs for your dynamic content previews to match your project's structure. Here's what you must do:

  • Ensure that the structure of these custom URLs matches your project's design and organization.

  • Link these custom URLs to your dynamic content preview components within your Next.js application.

Real-time updates

As you make changes in Kontent.ai, your Next.js application should automatically update in real-time. Let's break this down:

  • In your Next.js application, use the Kontent.ai SDK or API to fetch content for the custom preview URLs you've created.

  • Implement a mechanism to listen for updates triggered by Kontent.ai webhooks.

  • Whenever the webhooks indicate a change in content, automatically update the content on your custom preview URLs in real time.

  • Ensure that your application can handle and display these updates without requiring manual intervention.

By following these actionable steps, you can effectively set up dynamic content previews with Kontent.ai and Next.js, providing a real-time and accurate representation of your content as it will appear on your live website.

While implementing dynamic content previews with Kontent.ai and Next.js can significantly enhance your web development process, it's essential to be prepared for potential challenges and have troubleshooting strategies in place.

Content not updating in real-time

Here's what you must do if your content needs to update as expected in your Next.js application: 

  • Check Webhooks: Ensure your webhooks are correctly set up in your Kontent.ai project. Double-check the webhook URL and make sure it points to your Next.js application.

  • Monitoring and Logs: Implement monitoring and logs in your Next.js application to trace the webhook requests and responses, allowing you to identify any issues.

  • Cache-Control: Ensure that your Next.js application is not excessively caching content. Configure caching settings to allow for real-time updates.

Inconsistent content previews

The content displayed in your dynamic previews must be consistent with the live site. Here's what you must do if you have inconsistent content: 

  • Cache Management: Review your cache management strategy. Cached content may not reflect the most recent updates. Consider implementing cache-busting techniques.

  • Content Synchronization: Ensure the content types, fields, and structure are synchronized correctly between your Kontent.ai project and the Next.js application.

  • Content Drafts: Double-check if you preview content drafts instead of the published content. Ensure that you're fetching and rendering the correct version.

Performance issues

Dynamic content previews may slow down your Next.js application. Here is how you can fix that:

  • Optimize Queries: Ensure your queries to fetch content from Kontent.ai are optimized. Use GraphQL or other query optimization techniques to reduce the load on your server.

  • Caching Strategies: Implement innovative caching strategies to minimize the impact of real-time content updates on performance.

  • Server Resources: Monitor your server resources and scaling capabilities. Be prepared to scale your infrastructure if needed.

Design and layout problems

Here's what you must do if the design and layout in dynamic content previews are different than expected:

  • CSS Dependencies: Ensure your CSS dependencies are consistent between your development environment and Kontent.ai. Mismatched styles can lead to layout issues.

  • Media and Images: Confirm that media files, images, and assets are correctly linked in your content. Improper references can disrupt the layout.

  • Responsive Design: Check if your dynamic previews are responsive and adapt to various screen sizes.

Compatibility and browser issues

Here's what you must do if content previews may not display as intended in different browsers or devices.

  • Cross-Browser Testing: Regularly test your dynamic content previews in various browsers and devices to identify and address compatibility issues.

  • Polyfills: Use polyfills or feature detection to handle browser-specific discrepancies.

  • User Agent Sniffing: Employ user agent sniffing to adapt the content preview for specific browsers.

By addressing these common troubleshooting scenarios, you can ensure that your dynamic content previews with Kontent.ai and Next.js run smoothly.
