ember-data-query-first

Conveniently get the first item of a store.query().

If you are querying your adapter and an array is returned, but you only need the first entry:

// GET /users?email=[e-mail]
// {
//   data: [{
//     type: "user",
//     id: 1,
//     attributes: {
//       email: "[e-mail]"
//     }
//   }]
// }
store.queryFirst('user', { email: '[e-mail]' }).then(function(user) {
  console.log(`ID of the user: ${user.get("id")}`);
});

which is equivalent to:

store.query('user', { email: '[e-mail]' }).then(function(users) {
  return users.get("firstObject");
}).then(function(user) {
  console.log(`ID of the user: ${user.get("id")}`);
});

Note on store.queryRecord():

store.queryRecord() should be used when a single record is requested and the id is not known beforehand. store.queryRecord is most likely used with a custom implementation of urlForQueryRecord ond the adapter:

// app/adapters/user.js
import Adapter from './application';
 
export default Adapter.extend({
 
  urlForQueryRecord(query) {
    if (query.current) {
      return '/current_user';
    }
 
    return this._super(...arguments);
  }
 
});
 
// GET /current_user
// {
//   data: {
//     type: "user",
//     id: 1,
//     attributes: {
//       email: "[e-mail]"
//     }
//   }
// }
store.queryRecord('user', { current: true }).then(function(currentUser) {
  console.log(`ID of current user: ${currentUser.get("id")}`);
});
