Step-by-Step Tutorial: Create a Fullstack App with Java, Spring Boot, Thymeleaf, and HTMX without JavaScript
Introduction:
- Understand the Concept: HTMX is a library for JavaScript that allows back-end developers to work with the front end without using JavaScript.
- 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:
- 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:
-
Create a Model Class:
- Define a model class, e.g.,
Status
, with attributes like ID, user handle, user display name, and content.
- Define a model class, e.g.,
-
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.
- Implement a controller, e.g.,
Building the Frontend with Thymeleaf:
-
Create a View:
- Develop an HTML view, e.g.,
feed.html
, using Thymeleaf syntax. - Include HTMX CDN link for functionality.
- Develop an HTML view, e.g.,
-
Display Posts:
- Utilize Thymeleaf to iterate over the list of statuses and display them in a structured format.
Implementing Dynamic Loading with HTMX:
-
Add Load More Button:
- Introduce a button at the end of the post list to load more statuses.
-
Implement HTMX Functionality:
- Use HTMX attributes like
HX-get
,HX-swap
, andHX-indicator
on the button to trigger an Ajax call to fetch more statuses.
- Use HTMX attributes like
-
Update Controller for Dynamic Loading:
- Modify the controller method to handle requests for additional statuses based on the page number.
-
Update View for Dynamic Loading:
- Create a new view, e.g.,
statuses.html
, to display additional statuses when loaded.
- Create a new view, e.g.,
Testing and Running the Application:
-
Run the Application:
- Start the Spring Boot application and access the feed page in a web browser.
-
Test Dynamic Loading:
- Click on the "Load More" button to fetch and display more statuses without a full page reload.
Conclusion:
-
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.
