How to Fetch Dates from a List of Data in Angular?

In today’s digital world, dealing with JSON data from APIs is a common task for Angular developers. One of the challenges that developers often face is extracting specific information from dynamically generated strings. In this guide, we’ll explore how to fetch dates from a list of JSON filenames that adhere to a specific naming format.

Understanding the Problem

Imagine you receive a list of filenames in such a format:

In these filenames, the date is formatted as yyyy-mm-dd, which is surrounded by other dynamic data. The challenge is to extract just the date part from these strings, especially considering that the preceding parts of the filename can vary in length and content.

The Solution

To implement a solution, we can use JavaScript's string manipulation methods effectively. Below we break down the steps required to extract the date from each filename.

Step 1: Set Up Your Array of Filenames

First, initialize an array containing all your filenames. Here's how it looks:

Step 2: Create a Function to Extract the Date

Next, we will create a function that takes a filename as input and returns the date. We can use the .split() method with regular expressions to achieve this.

Here's the function:

Step 3: Loop Through Filenames and Log the Dates

Finally, we use a loop to go through each filename, applying our getDate function to extract and log the date.

Here’s how that looks:
