Guides

Complete YAWP! Guides.

Getting Started

1. At the command prompt, create a new YAWP! Kotlin application:

    $ mvn archetype:generate \
        -DarchetypeGroupId=io.yawp \
        -DarchetypeArtifactId=yawp \
        -DarchetypeVersion=LATEST \
        -DgroupId=yawpapp \
        -DartifactId=yawpapp \
        -Dversion=1.0-SNAPSHOT \
        -Dlang=kotlin            
   

2. Change directory to yawpapp and start the yawp development server:

    $ cd yawpapp
    $ mvn yawp:devserver
   

3. Using a browser, go to http://localhost:8080/api to check if everything is OK.

4. Using a scaffolder, create a simple endpoint model:

    $ mvn yawp:endpoint -Dmodel=person
   

   Output:

   @Endpoint(path = "/people")
   class Person(@Id
                var id: IdRef<Person>)

   Try it:

    $ curl http://localhost:8080/api/people
   

   From Javascript:

    $ npm install yawp --save
   

   class Person extends yawp('/people') {
       save() {
           console.log('saving...');
           return super.save();
       }
   }
   const person = new Person({name: 'Janes'});
   person.save()  

5. Follow the guidelines to start developing your API:

   • Your First API
   • The Javascript Client
   • Todo App List Tutorial
   • API Documentation

Contributing

Everyone willing to contribute with YAWP! is welcome. To start developing you will need an environment with:

• JDK 1.8+
• Maven 3.3+
• PostgreSQL 9.4+
• phantomjs 2+

For postgres, you need to create a database/user with access from your Unix user (you need to be able to run psql with no args). A simple tutorial for Arch can be found here.

Phantomjs can be installed from pacman on Arch.

Then follow the travis-ci build script to get your build working.
