JSweet quick start
A simple project to get started with JSweet. This project just contains a main method that shows 'Hello world' messages in two different ways. The program uses the J4TS candy to access java.util
API, and the jQuery candy. Programmers can use it to set up a new JSweet project and try out some basic features.
Usage
> git clone https://github.com/cincheo/jsweet-quickstart.git
> cd jsweet-quickstart
> mvn generate-sources
> firefox webapp/index.html
Modify
At any time, you can modify the Java files (or add new files) and run mvn generate-sources
to generate the corresponding JavaScript files. You can then use them in the index.html
file (<script>
tags).
You can modify the generation options by modifying the plugin section for jsweet-maven-plugin
. When having a project with multiple source files, a good generation option to turn on is the bundle
option, in order to generate all the JavaScript classes in a single file. Check the Maven plugin for the full option list.
If you want to use a JavaScript library (besides jQuery which is already enabled), you must add the Maven dependency in the <dependencies>
section of the pom.xml
. You can copy-paste the Maven dependency description from our Candy browser, or from our online Maven repository. When running mvn generate-sources
with a new library, if available in the candy, the JavaScript library will be extracted to the location given by the candiesJsOut
option (here in the webapp
directory). JavaScript libraries are packaged in the Jar following the WebJars conventions. When not available, you will need to find and download the JavaScript library manually (or using a third-party tool such as Bower).
