Welcome back to our 'Full Stack Development with Express.js' series! In this second episode, we delve deeper into building our Character Level-Up API. This session is all about enhancing our server's capabilities and understanding how to handle and test HTTP requests.
What we cover in this video:
Implementing express.static to serve static files from the 'public' directory.
Using express.urlencoded to parse URL-encoded data sent from the client.
Creating and testing the GET /character endpoint to retrieve character data.
Developing the POST /levelup endpoint to update character levels and handle various edge cases.
Understanding the request body, different types of request payloads, and their significance.
Setting up and using Hoppscotch.io for testing our API endpoints.
Adding advanced features like custom 400 status codes for better error handling.
In this practical session, we code out the remaining server functionality and the filesystem code required for our service. We'll go through the process of setting up, discussing, and testing our two main endpoints: GET /character and POST /levelup. I'll explain the concepts behind the request body, the different types of request payloads, and how HTML form submission is handled with URL-encoded data.
We also dive into some advanced features, introducing custom 400 status codes to enhance our application's error handling capabilities. This is a crucial step in creating robust and user-friendly web applications.
Join me as we build and test these critical components of our Express.js server. By the end of this tutorial, you'll have a better understanding of server-side logic and API testing, essential skills for any aspiring full-stack developer.
