Ways to confirm the specific data in the Firebase database node

There is a JSON structure that looks like this:

    {
    "engagedUsers": {
        "qwe": {
          "agent_availability": true,
          "conv_id": "parthengineer_qwe",
          "emailId": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6d1c1a082d0a000c04">[email protected]</a>",
          "login_time": 1512644440,
          "name": "qwe",
          "uid": "adasfklsfjdskldgsgjgjkl"
        },
        "tt": {
          "agent_availability": true,
          "conv_id": "genesis_tt",
          "emailId": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a7d3d3e7">[email protected]</a>",
          "login_time": 1512644440,
          "name": "tt",
          "uid": "adasfklsfjdskldgsgjgjkl"
        }
      }
    }

I am trying to check if the value of the 'conv_id' child is equal to parthengineer_qwe. However, my current code is not working as expected:

this.engagedRef = firebase.database().ref('engagedUsers');
this.engagedRef.orderByValue().once('value', function (snapshot) {

    snapshot.forEach(function (data) {
      if ((data.child('conv_id').val() == 'parthengineerqwe') && (existEngageduser !== 1)) {
        existEngageduser = 1
      }
      if (existEngageduser == 1) {
        isEngaged = true
      }
    })
    return isEngaged;

  });

I am looking for a better approach to achieve this, as I want the isEngaged variable to be true. Any suggestions?

Answer №1

I'm a bit uncertain about your request, but have you considered creating an external function to handle it?

snapshot.forEach(function (data) {
    if (isEngaged(data.val())) {
      console.log(data.key, ' is engaged');
    }
}

function isEngaged(userData) {
    return (userData.conv_id === 'parthengineer_qwe') || false;
}
