Dealing with Firebase Range Queries Results

Hello, I am currently working on managing responses from a Firebase REST service as outlined in https://firebase.google.com/docs/database/rest/retrieve-data. Below is an example of the response I am getting:

{
  "2": {
    "name": "John",
    "surname": "Cena"
  },
  "12": {
    "name": "Murphy",
    "surname": "R ichard"
  },
  .
  .
  .
  "8": {
    "name": "Alisha",
    "surname": "Johnson"
  }
}

Essentially, the response consists of random keys and employee details:

interface Employee{
  private name:string;
  private surname:string;
}

The number of elements in the response can vary. I am looking to handle this in TypeScript. The response comes back as an Object and not even an array or map.

I aim to extract an array of Employees

. Any suggestions on how to approach this would be greatly appreciated.

Answer №1

When it comes to handling data, the approach you take depends on your specific needs

// You have options for processing the response object
const employees: any = res;

// Alternatively, you can transform it into an array
const data = Object.keys(res).map((key) => {
  return { ...res[key], id: key }; <-- By passing this to a constructor, you can create an Employee Object with an added key/id field.
});

// There are multiple ways of dealing with data, depending on how you intend to use it.
