Example Todo app built with Angular 2, PrimeNG, and Java (using JSweet on the front-end and JAX-RS on the back-end)

This is part of the sample application for the presentation "Full Stack Java with JSweet, Angular 2, PrimeNG, and JAX-RS", originally given at JavaOne in September, 2016 by Kito D. Mann from Virtua, Inc.. It demonstrates how you can write an Angular 2 application with PrimeNG components using Java (courtesy of the JSweet transpiler), and have it talk to a standard Java back-end using JAX-RS.

This repository contains the front-end code; the back-end and slides are in separate repositories.

This project was forked from the Angular 2 Quickstart with Java; see that project for a simpler example without a back-end. There is also a JSweet PrimeNG Quickstart project available without a back-end.

Special thanks to Renaud Pawlak (JSweet lead developer) for his extensive assistance with getting this project working!

NOTE: This project uses the Angular 2.0RC5 and PrimeNG 1.0.0-beta.14 JSweet candies. In order to upgrade to newer versions, those candies must be manually upgraded. If you do that, please create a pull request!

Prerequisites

Node.js > v4.x.x and npm > v3.x.x.

Verify that you are running at least node v4.x.x and npm 3.x.x by running node -v and npm -v in a terminal/console window. Older versions produce errors.

Maven (for compiling with JSweet).

Getting started

Clone the project.

git clone  https://github.com/cincheo/jsweet-Angular 2-quickstart my-proj
cd my-proj

Compile JSweet sources (located in: src/main/java).

mvn generate-sources

Note: you can also use Eclipse to compile (see the JSweet Eclipse plugin).

Install the npm packages described in the package.json and verify that it works:

Attention Windows Developers: You must run all of these commands in administrator mode.

npm install
npm start

This will open the application in your browser. If you compile again the Java source files, the application will automatically reload. Shut it down manually with Ctrl-C.

NOTE: If you have problems compiling fileupload.d.ts, edit the file and replace all references to DomSanitize with DomSanitizationService. This appears to be a bug with the version of PrimeNG used in the project.

How to extend the application

You can add new classes in the app package (src/main/java). Please be aware that in JSweet, each package is a module. So, all the classes defined in a given package will belong to the same TypeScript/JavaScript module.

New templates should be placed in the app folder.

A minimal Angular 2 API is defined in the def.angular package (the def package in JSweet is by convention similar to a d.ts file in TypeScript: it holds external declarations). When extending the application, you will need to provide the API elements that you are using and that would be missing in the current definitions.

If you want to use external JavaSript libraries, check out JSweet candies rather than writing definitions manually. Here definitions have to be written manually for Angular 2 because the corresponding candy does not exist yet.

Setup the back-end

Visit the angular-primeng-jsweet-todo-server project and clone the Java-based back-end built using Jersey and JAX-RS. See the README for that repository for more information.
