Syntax: simplify launch script

[louisdussarps]

Today, if you want to be able to start an action, you 've to :

• define the action
• register the action in an app
• bootstrap the app and wait for the app to be ready
  Then you can resume the action.

Most simple example is thus :

@bootstrapApp({
    db : {
        mongo: {
            url: dbUrl
        }
    }
})
export class ExampleApp extends ActionApp{
    declare = [CiPipeline, PrintAction, WaitAction]
}


ActionApp.waitForActiveApp.then(()=>{
    console.log("waitforactive app")
    ActionApp.activeApp.ActionModel.findOne({
        filter : {
            main : true
        }
    }).then((actionDb)=>{
        console.log("actionDbFinding")
        if(actionDb){
            const pipeline = Action.constructFromDb(actionDb);
            return pipeline.resume();
        }
        
        //create main action
        const pipeline = new CiPipeline();
        pipeline.setFilter({
            main : true
        })
        pipeline.dbDoc.save();
    })
})

We want this to be shorten

One solution can be, in order to remove the app part, to use decorator :
On every action, we would do :

@registerAction
export class MyAction extends Action{
}

Then on the index file, we would only need to do :

new App({url : ....})

const myAction = new MyAction();
myAction.resume();
