Execute traverse statement in orientjs - orientdb

Question

I'm using an OrientDB graph database, I have two vertexes Room and Participant, I have created a few edges between Room and Participant records and I want to execute the following command using orientjs driver:
select from (traverse out() from (select from room where name='room test 1')) where #class='Participant'
Updated
I have in mind to use something like this:
db.let('firstSelect', function(s){
s.select().from('room').where({name:'room test 1'});
}).let('traverse', function(s){
s.traverse('out()').from('$firstSelect').while('$depth<=1');
}).let('finalSelect', function(s){
s.select().from('$traverse').where({'#class':'Participant'});
}).commit()
.return('$finalSelect')
.all()
.then(function(participants){
console.log(participants);
})
In the future I will put this code in a function with some parametters

You could use the db.query API:
var OrientDB = require('orientjs');
var server = OrientDB({
host: 'localhost',
port: 2424,
username: 'root',
password: 'root'
});
var db = server.use({
name: 'OrientJStest',
username: 'root',
password: 'root'
});
db.query('select from (traverse out() from (select from room where name="room test 1")) where #class = :inputClass', {
params: {
inputClass: "Participant"
},
limit: -1
}).then(function (results) {
console.log('Vertexes found: ');
console.log();
console.log(results);
});
Hope it helps
