Overview

I had the opportunity to create a web application from scratch with Python, so as a summary! This article is about building an environment.

I want this person to read

Those who have no programming experience but want to make an app
New web programmers
Experienced but never written a web app in Python

goal

The goal is to create a web app with CURD functionality using HTML, CSS, JavaScript, Python, and SQL.

Things necessary

PC（Windows OS）
Internet line
Exciting feelings

1. Install Python

You can download it from the official website. Download Python | Python.org

After starting the installer, check "Add Python 3.8 to PATH" and click "Install Now".

Start the command prompt, enter python, and when it looks like the image, the installation is successful.

2. Install Visual Studio Code

You can download it from the official website. Visual Studio Code - Code Editing. Redefined

Start the installer and basically proceed to the next step. If you check "Add [Open with Code] action to the file context menu of Explorer" and "Add [Open with Code] action to the directory context menu of Explorer", right-click the folder on Explorer. It is convenient because you can open it with VS Code.

3. Install the Visual Studio Code plugin

VS Code distributes many useful extensions. You can check it from the sidebar. For the time being, I'm putting it in & I'll introduce the minimum that I'm likely to use this time.

Japanese Language Pack for Visual Studio Code It translates the default English VS Code into Japanese.

Python You can run Python on VS Code.

Prettier - Code formatter I'm a code formatter. (The one that automatically adjusts the indentation and space of the code) There is also a VSCode standard formatter, but I use Prettier because it is wide and easy to customize.

4. Install PostgreSQL

You can download it from the EDB site. Download PostgreSQL Database for Windows, Linux and MacOS & 32-bit or 64-bit Versions | EDB

Start the installer and basically proceed to the next step. pgAdmin4 is a GUI tool for handling PostgreSQL easily. Without this, the operation (command line) will be from the CLI, so if you are not familiar with it, please install it with pgAdmin4 checked.

Summary

Up to here for this time! We have prepared a server-side language, database, and code editor environment!
