Alright, so we need to wrap up our query in a function as in :


const aql = require('@arangodb').aql;

router.get('/entries', function (req, res) {
  const keys = db._query(aql`
    FOR entry IN ${foxxColl}
    RETURN entry._key
  `);
  res.send(keys);
})*.response(joi.array().items(
  joi.string().required()*
).required(), 'List of entry keys.')
.summary('List entry keys')
.description('Assembles a list of keys of entries in the collection.');

Why do we need to joi filter the output ?


Also could you explain this syntax

*`Hello ${req.pathParams.name}` *

from 

*const joi = require('joi');

router.get('/hello/:name', function (req, res) {
  res.send(`Hello ${req.pathParams.name}`);
})*


$ in this too :

 

*${foxxColl}*
