背景：

前端專案採用Nginx部署在雲上

``` server { server_name www.domain.com; client_max_body_size 10m;

location /chairong/dist {
  root /home/user/frontend;
  try_files $uri $uri/ /project-name/dist/index.html;
}

location = / {
  rewrite (.*) project-name/dist permanent;
}

...

} ```

本地安裝了python3.8+和fabric（如果是windows系統需配置一下，讓fab命令可用）

$cat fabfile.py # 該檔案放在前端程式碼倉庫裡，與package.json同級目錄

`` __author__ = "WJ" """ Auto update server deploy ~~~~~~~~~~~~~~~~~~~~~~~~~ 前端output_dir包自動部署指令碼 自動將yarn pre構建出來的output_dir`資料夾，替換掉測試伺服器上的舊資料夾 Usage: - For windows 1. Install python3.8 2. pip install fabric 3. add folder of fab.exe to environment path

Example: /c/Users/Administrator/AppData/Roaming/Python/Python38/Scripts/

1. then open git bash and run the following command: $ fab pre
2. For linux
3. just run: $ cd /path/to/project && (which fab||pip install fabric --user) && fab dist """ import os from datetime import datetime from os.path import getmtime from pathlib import Path from typing import Union
