Use React (http://facebook.github.io/react/index.html) together with Tapestry (http://tapestry.apache.org/).
This library provides basic integration for using JSX templates with Tapestry.
repositories {
maven { url "https://jitpack.io" }
}
dependencies {
implementation 'com.github.eddyson-de:tapestry-react:0.36.0'
}
That's it, now you can import modules written in JSX. Just give them the .jsx(m) extension and they will be compiled to JavaScript automatically.
define(['t5/core/dom', 'react', 'react-dom'], function(dom, React, ReactDOM) {
var HelloMessage = React.createClass({
render: function() {
return <div>Hello {this.props.name}</div>;
}
});
var mountNode = (dom('example')).element;
ReactDOM.render(<HelloMessage name="John" />, mountNode);
});You can also use the ReactComponent component to keep the components' code separate from the page code:
define(['react'], function(React) {
return React.createClass({
render: function() {
return <div>Hello {this.props.name}</div>;
}
});
});<html title="React Demo Index"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_4.xsd"
xmlns:r="tapestry-library:react">
<div class="row">
<div class="col-md-10 col-md-offset-1 col-lg-8 col-lg-offset-2">
<r:reactcomponent module="app/react/HelloMessage" name="John"/>
</div>
</div>
</html>If you want to write your classes as ES6 rather than AMD moudules, just use the .jsxm file extension to switch the transpiler to AMD output.
import React from 'react'
export default class HelloMessage extends React.Component {
constructor(props){
super(props);
}
render(){
return (
<div>Hello {this.props.name}!</div>
)
}
}If you want code to be executed only in development mode but not in production, you can use the __DEV__ pseudo variable:
if (__DEV__) {
MyComponent.propTypes = {
...
}
}This will be compiled to if (true) or if (false) depending on the value of the tapestry.production-mode symbol.
If you want to compile code outside of a Tapestry application (e.g. in your Gradle build), you can use the de.eddyson.tapestry.react.StandaloneCompiler and de.eddyson.tapestry.react.readers.CompilingBabelReader classes.
Unfortunately, there is no live demo available, but the test application can be examined by running ./gradlew runTestApp and pointing your browser to http://localhost:9040/.
Compiling templates can take some time. Combined with minification, this can quickly lead to Require.js timeouts in production.
To speed things up, you can have the files pre-compiled and minified upon registry startup using https://github.com/eddyson-de/tapestry-minification-cache-warming.
You will probably end up having a lot of React components that do not have an associated page class. If this is the case and you find yourself wanting a proper REST API rather than component- or page-level event handlers, have a look at https://github.com/tynamo/tapestry-resteasy.
