Web Crawling with Node.js

With the arrival of the AI era, the skills required of developers are becoming increasingly complex. You might have thought, "I just need to be good at frontend," but when you try to create your own service or integrate AI features, you eventually hit a massive wall called the backend. However, as you try to start backend development, are you overwhelmed by how much there is to learn—from database design and authentication (Auth) to storage management and complex infrastructure setup? Now, you can lay down that heavy burden. In this course, we use Supabase, which solves all these backend functions at once. We will guide you through the fastest shortcut to becoming a full-stack developer who can "instantly" complete a backend without complex server knowledge and bring ideas to life immediately.

You will learn about what a node is, the latest JavaScript grammar, the node API, npm, the module system, databases, testing, and more. You will create a project using five practical examples. You will also deploy a service to the cloud and convert a node project to TypeScript.

In this lecture, we will practice developing programming thinking skills using JavaScript.

This article introduces the relationship between Nodejs, a server-side JavaScript language, and a database, and explains how to create web applications using Nodejs and a database.

We will show you how to create a web application using JavaScript and Nodejs. You can use JavaScript, which runs in a web browser, to replace the role of PHP or JSP. You can implement the entire web application in one language.

This course covers practical Web APIs. I hope you gain the tools to solve requirements you are bound to encounter at least once in the field.

In this class, you will learn techniques for retrieving (crawling) and processing data from various operating sites using Python, and apply them directly to various examples that you may encounter in the field. Through this, you will learn techniques that focus on solving practical problems based on an understanding of the basic principles of how the web works, rather than one-dimensional task automation by copying and pasting given codes, and accordingly, you will be able to collect and process data from any site in the future. You will also learn how to resolve various exceptions that occur in this process with code, and ultimately, you will be able to solve and automate various problems that occur in daily life with programming thinking.

This is a process of creating your own backend API server, using Node-based Strapi v4, without any additional coding, with just a few clicks, and deploying it to AWS EC2. Almost the same can be applied to Strapi v5. Please refer to the lecture A/S as well~
