When the virus was in full swing, many developers created and distributed a map service showing the status and route of the virus in Korea. In particular, this map service was developed to make it easy to intuitively grasp the status of the virus, and many people were helped!

It can be seen that developing such intuitive services is becoming more and more important for future continuous non-face-to-face situations. Through this class, I would like to summarize the A-Z for creating such a service and make it easy for you to know.

# What will I learn in this class?

Edit Image Info

What websites do we commonly come across

1. front-end front-end representing the screen,

2. Back-end back-end that implements business logic,

3. DB server where data is stored

4. Server settings that enable communication on the web

All 4 steps have been completed.

By taking this class, you will learn all 4 steps using full-stack (full-stack), that is, React.js (front-end), Node.js (back-end), MySQL (DB), and AWS (DB server, web server).

# You will develop your own case guidance service!

1. Using the React server, you can display the UI of your desired design on the screen.

2. Using the Node server, you can send and receive data between the React server and the DB server.

3. You will be able to implement functions for querying, inserting, modifying, and deleting data on the DB server.

4. Functions 1 to 3 implemented on a local PC can be deployed to an AWS server that can also be accessed from outside.

5. The goal of this lesson is to develop by expanding the desired functions by framing 1 to 4 as a set.

6. You will also learn how to use Kakao Maps and use an external API.

# What makes this class different from other development classes?

1. Learn all about front desk, backend, DB, server settings, and source deployment.

2. You will also learn essential concepts & elements of a web project.

3. We will provide course materials that you can follow as they are.

4. I'll explain it very easily based on my experience working in IT with non-majors.

# What kind of people would you recommend this class for?

1. Those who want to do everything from development to direct cloud server deployment

2. Planners, designers, marketers, sales, and founders who have trouble collaborating with developers due to lack of IT knowledge

3. Those who are developers of other languages and want to expand their language range

4. Those who need a website with their own design and data

5. Those who need a portfolio that can be demonstrated on the web

# Products and development tools used by classes

What is React?

Edit Image Info

It's a JavaScript library developed by Facebook. A user interface, that is, a language that creates a website's screen (view).

In React, there is a screen configuration unit called a component. It is convenient to modularize screen components and implant them where needed.

Using components, a screen that is commonly used on multiple pages can be implemented and reused as a single component.

What is a Node?

Edit Image Info

Node is also a Javascript based language. If React is used to configure a screen, nodes are used to connect complex logic or databases that are invisible to the eye.

So I usually use Node as a backend language a lot. The biggest difference between front-end languages and back-end languages is that only back-end languages can link databases.

What is MySQL?

Edit Image Info

It is one of the systems that manage databases, and performs the functions of querying, registering, modifying, and deleting data by receiving parameters from the backend server.

The reason we use a database is to maintain data.

Data used by React or Nodes is temporary and will disappear over time. The reason this data can be kept without losing it is because it is stored in a database.

What is AWS (Amazon Web Services)?

Edit Image Info

If you develop React, Node, and MySQL as described above only on a PC (personal laptop, desktop), only you can see the finished result. If you want others to share your site with others,

You need to run the project on an “externally accessible server”. Cloud services such as aws make it very easy and simple to create an “externally accessible server.”

If there is no cloud server, the developer must purchase additional expensive hardware, install an operating system, and go through a complicated process to set up the server.

However, since cloud services rent only the hardware they have set up for themselves as needed, they can use the server inexpensively and efficiently.

# Training environment guide

A desktop or laptop computer using the Windows operating system is required.
To sign up for AWS, you must register a payment method. A visa or master card that can be used for overseas payments is required. Both debit cards and credit cards are accepted, and since the free version (free tier) is used, there is no charge.
