Rocker is an innovative template engine optimized for Java 8 and beyond, enabling developers to create swift, statically-typed templates with remarkable ease. In this article, we’ll guide you through the process of creating and using Rocker templates effectively, ensuring a seamless experience when rendering your dynamic content.
Introducing Rocker Templates: The Basics
Imagine you are a chef preparing various dishes for a large gathering. Every dish requires different ingredients and preparation methods, but there are some common elements like plates, utensils, and even the cooking techniques you use. Rocker templates work similarly. You create templates that can be thought of as the common plates and utensils; they help in organizing your content while allowing you to tailor the ingredients according to your needs.
Setting Up Rocker in Your Project
To begin using Rocker, you need to include it in your project dependency. Here’s how to set it up:
- For Maven projects, add the following dependencies to your
pom.xml
:
com.fizzed
rocker-runtime
1.3.0
com.fizzed
rocker-compiler
1.3.0
provided
build.gradle
:
repositories {
mavenCentral()
}
dependencies {
compile group: 'com.fizzed', name: 'rocker-runtime', version: '1.3.0'
}
Creating Your First Template
Now, let’s create a simple template that showcases your content. At your designated template directory, create HelloWorld.rocker.html
with the following content:
@* Example of hello world *@
@args (String message)
Hello @message!
Rendering the Template
Once your template is set up, you can render it using the following Java code:
static public void main(String[] args) {
String output = views.HelloWorld.template("World").render().toString();
System.out.println(output);
}
Features of Rocker Templates
- Optimized for performance with near-zero copy rendering.
- Statically typed templates compiled with your Java code.
- Hot reload support for dynamic development.
- Intuitive and tagless syntax for easier coding.
Troubleshooting Common Issues
While using Rocker templates, you might encounter some common challenges. Here are some troubleshooting tips:
- Issue: Template fails to render.
Ensure that your template file is properly named and located in the specified directories as defined in your build configuration. - Issue: Dependency conflicts.
Check your project’s dependency tree for conflicting libraries that might affect the functionality of Rocker. - Template compilation errors.
Examine the error message for issue specifics. Commonly, syntax errors or incorrect arguments might be the culprits.
