Extracting and Converting JSON Data with JavaScript: A Simple Guide to token_dict Conversion

Have you ever received data from an API in a format that's not easy to work with? If you've encountered the token_dict object in JSON format and need to convert it into a more usable array format, you're not alone. This post will guide you through the process using JavaScript, making it both straightforward and efficient.

Understanding the Problem

When working with APIs, the data received can often come in complex structures. In our example, the token_dict is structured as an object where each property is a unique token ID pointing to another object containing various properties such as chain, decimals, name, and more. Here's a snippet of the JSON we’re working with:

The goal here is to convert this complex object into an array of tokens where each token is represented as an object in the array. This new structure is simpler to work with, especially for rendering or manipulations in applications like Bubble.

Solution Overview

Step 1: Retrieve Property Keys

Step 2: Map Keys to Values

Using .map(), we can create a new array where each element is the value corresponding to each token ID. This means we don't have to manually extract each token and can do it in a clean and compact way.

Implementation

Here's how we can implement this logic in JavaScript:

Output Explanation

The output will be an array that resembles the following structure:

Note on Best Practices

This approach works well given that we are unable to change the API response structure on the server side. If you have the ability to modify the API, returning the data in an array format directly would be the best solution, reducing unnecessary processing on the client side.
