- Publish the changes to see them in the sample app.
Voila! You have successfully updated content in your Sample Project. Refresh the browser window with your application to see the changes on the website.
Feel free to further explore how the content in your sample project is structured.
Exploring content structure

How content is structured in Kentico Kontent
Each content item is based on a single content type. A content type is a template that defines the structure of the content item – which elements it contains, their names, limitations, guidelines, and so on.
Mix and match the available elements to define your own content types.
When using a headless CMS like Kentico Kontent to power a single page application, you don't necessarily have to write any server-side code. Because the application only requires static resources, you have many interesting deployment options available to you.
Here, you're going to use SurgeOpens in a new window to deploy your Express.js sample app:
- Navigate to the root folder of the application in the command line.
npm install --global surgeto install Surge on your computer.
npm run buildto build the application and make it production-ready.
cd buildto navigate to the build folder.
surgeto deploy your application. The first time you do this, Surge will prompt you to set up your account. Every other time it will confirm the build directory and generate a funny subdomain for your app.
You can change the subdomain if you like and can even use your own domain, all for free. After that, you’re done. The site is deployed and ready to be accessed on the domain specified during deployment.
Kentico Kontent makes no assumptions about how your content is displayed. It simply delivers it via a RESTful Delivery API to any application that asks for it – be it a website, mobile app, chatbot, electronic billboard, virtual voice assistant or an internet-enabled toaster.
We deliver the content, you do whatever you want with it – using the technology of your choice.
A traditional CMS would force you to put your content into neatly arranged boxes to fit inside a pre-defined template. The power of Kentico Kontent comes from not getting in your way. Content structure and content presentation are truly separated and you have the flexibility to define both according to the needs of your project.
