What is the best way to establish a model using a date index?

I'm trying to access an API using Angular that returns an array with dates as indexes.

After attempting to create a model, I encountered some issues. How should I modify it?

This is what the API response looks like:

{
    "Information": {
        "Created": "2019-04-25",
        "Version": "1.2"
    },
    "Files": {
        "2019-04-26": {
           'name': 'file1',
           'size': 5,
        },
        "2019-04-25": {
            'name': 'file2',
            'size': 3,
        },
    ...
        }
    }

My current model is structured as follows:

export class Model {
  'Information': {
    'Created': String,
    'Version': String,
  };
  Files: [

    {
     'Date': String,
     'name': String,
     'size': number,
    }
    ];

}

If you're looking to define a structure with an index signature in TypeScript, you can use the following syntax:

export class Model {
  'Information': {
    'Created': string,
    'Version': string,
  },
  'Files': { 
    [date:string]: {
     'name': string,
     'size': number,
    }
  }
}

This defines a class Model with a property Files that is an object with string keys, each corresponding to an object containing a name and size property. The keys don't have to follow a specific date pattern.

Alternatively, you could create a function that transforms this object into an array of objects where each element includes the date along with name and size properties. Here's how the model would look in that case:

export class Model {
  'Information': {
    'Created': string,
    'Version': string,
  },
  'Files': { 
    'date': string, // This could also be typed as Date if needed
    'name': string,
    'size': number,
  }[]
}
