Create a FULLSTACK APP with Java+Spring-Boot+Thymeleaf+HTMX | NO Javascript | Tutorial

Step-by-Step Tutorial: Create a Fullstack App with Java, Spring Boot, Thymeleaf, and HTMX without JavaScript

Introduction:

1. Understand the Concept: HTMX is a library for JavaScript that allows back-end developers to work with the front end without using JavaScript.
2. Advantages of HTMX: HTMX enables the usage of modern browser features, such as Ajax, animations, and more, without the need for complex JavaScript frameworks like React or Angular.

Setting Up the Project:

3. Create a New Spring Boot Project:
   • Use IntelliJ IDEA and the Spring Initializer to set up the project.
   • Include dependencies for Spring Web and Thymeleaf in the pom.xml file.

Implementing the Backend:

4. Create a Model Class:

   • Define a model class, e.g., Status, with attributes like ID, user handle, user display name, and content.

5. Create a Controller:

   • Implement a controller, e.g., StatusController, to handle requests.
   • Define a method to populate the initial state with random statuses and return them to the view.

Building the Frontend with Thymeleaf:

6. Create a View:

   • Develop an HTML view, e.g., feed.html, using Thymeleaf syntax.
   • Include HTMX CDN link for functionality.

7. Display Posts:

   • Utilize Thymeleaf to iterate over the list of statuses and display them in a structured format.

Implementing Dynamic Loading with HTMX:

8. Add Load More Button:

   • Introduce a button at the end of the post list to load more statuses.

9. Implement HTMX Functionality:

   • Use HTMX attributes like HX-get, HX-swap, and HX-indicator on the button to trigger an Ajax call to fetch more statuses.

10. Update Controller for Dynamic Loading:

    • Modify the controller method to handle requests for additional statuses based on the page number.

11. Update View for Dynamic Loading:

    • Create a new view, e.g., statuses.html, to display additional statuses when loaded.

Testing and Running the Application:

12. Run the Application:

    • Start the Spring Boot application and access the feed page in a web browser.

13. Test Dynamic Loading:

    • Click on the "Load More" button to fetch and display more statuses without a full page reload.

Conclusion:

14. Explore Further:

    • Understand the capabilities of HTMX and its potential in simplifying front-end development for Java developers.
    • Consider the scenarios where HTMX can be a suitable alternative to JavaScript frameworks like React or Angular.

15. Feedback and Engagement:

    • Share your thoughts on HTMX and its usability in the comments section of the video.
    • Subscribe, like, and share the video to support the content creator for more tutorials.

By following these steps, you can create a full-stack application using Java, Spring Boot, Thymeleaf, and HTMX without the need for extensive JavaScript coding. Enjoy building modern web applications with a simplified development approach!
