Code that generates a JSON object based on a .json file

I'm currently working on a function that is designed to extract data from a locally stored .json file, specifically one called products.json. The function in question looks like this:

async function getJSON_Format(){

    let response = await fetch(api);
    let data = await response.json();
    
    // console.log(data);

    return data;    
    
}

The variable api represents the file path for products.json. My goal is to retrieve all the information contained within products.json and save it as a JSON object variable using a line similar to

let json_object = getJSON_Format();

. However, the current issue is that this returns a promise.

I am seeking advice on how to address this problem. Any suggestions?

Answer №1

Since your function is marked as async, remember to use await when calling it. For example:

let data = await fetchJSON_Data();

However, you must ensure that this code block is inside an async function.

Alternatively, you can handle it as a Promise and utilize the then method like so:

fetchJSON_Data().then(data => {
  // perform operations on data here
});

I have also modified the variable name from json_object to simply obj. Keep in mind that the term "JSON object" is misleading, as something is either JSON (text) or an actual Javascript object.
