Today we’re going to learn how to get and manipulate data from an external API. We’ll use a practical example from one of my current projects that you will hopefully be able to use as a template when starting something of your own.
For this exercise, we will look at current job posting data for New York City agencies. New York City is great about publishing all sorts of datasets, but I chose this particular one because it doesn’t require dealing with API keys — the endpoint is a publicly accessible URL.
Here’s a quick roadmap of of our plan. We’ll get the data from New York City’s servers by using JavaScript’s Fetch API, which is a good way to start working with promises. I’ll go over the very bare basics here, but I recommend Mariko Kosaka’s excellent illustrated blog The Promise of a Burger Party for a more thorough (and delicious) primer.
