What would you like to do?
A FeathersJS hook to implement `findOrCreate`
const findOrCreate = require('./hook.find-or-create.js')
app.service('messages').hooks({
before: {
create: [findOrCreate()]
}
})
'use strict';
/**
* If the record doesn't already exist, create it and return it to the user.
*/
module.exports = function(){
return function(hook){
const service = hook.app.service('/api/records');
let params = {
query: hook.params.data,
user: hook.params.user
};
return service.find(params)
.then(response => {
// If a service has pagination enabled or not, handle either way.
response = response.data || response;
if (data.length) {
// Set `hook.result` to skip the db call to `create` if a record was found.
hook.result = response[0];
}
// Return the `hook` object for the next hook to use.
return hook;
});
};

line 18 data should be response i guess.

Improvement: line 7 - use 'hook.path' to generalize for all services.

Fix: line 9 - should be 'hook.data'.

Very helpful!
