想掌握一套 web 全栈开发技术，用于开发、验证小项目，但不想花太大学习成本，需要一套轻量、简洁、易上手的技术栈。

查找一些资料之后，最终的选择如下

后端：flask 前端：htmlx+Tailwind CSS+daisyUI

  • htmlx 可以在html中使用属性发送 AJAX 请求，处理服务器响应，可以替换大部分需要 JavaScript 来实现功能。
  • Tailwind CSS 可以让我们在 html 中添加特定的工具类便能完成页面布局，无须单独写css。
  • daisyUI 则是一个基于 Tailwind CSS 的组件库，简化 Tailwind CSS 的使用。

搭建步骤

安装 python 和 flask 环境

1
2

py -3 -m venv venv
.\venv\Scripts\Activate.ps1

1

pip install flask flask-assets

安装 Tailwind CSS 和 daisyUI

1
2

npm i -D daisyui@latest
npm install -D @tailwindcss/typography

如果不需要 daisyUI 组件，可以直接使用 Tailwind CSS 的命令行工具，而不需要安装 npm 和 nodejs。

1

pip install pytailwindcss

如果要 daisyUI 暂时没办法，没有独立的安装工具。

下载 htmlx

下载 htmx.min.js 到 static\src\htmx.min.js 路径

整合 Tailwind CSS 到 flask

1

npx tailwindcss init

修改 tailwind.config.js

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./templates/**/*.html",
  ],
  theme: {
    extend: {},
  },
  plugins: [require("@tailwindcss/typography"), require("daisyui")],
  // daisyUI config (optional - here are the default values)
  daisyui: {
    themes: false, // true: all themes | false: only light + dark | array: specific themes like this ["light", "dark", "cupcake"]
    darkTheme: "dark", // name of one of the included themes for dark mode
    base: true, // applies background color and foreground color for root element by default
    styled: true, // include daisyUI colors and design decisions for all components
    utils: true, // adds responsive and modifier utility classes
    rtl: false, // rotate style direction from left-to-right to right-to-left. You also need to add dir="rtl" to your html tag and install `tailwindcss-flip` plugin for Tailwind CSS.
    prefix: "", // prefix for daisyUI classnames (components, modifiers and responsive class names. Not colors)
    logs: true, // Shows info about daisyUI version and used config in the console when building your CSS
  },
}

增加文件 static\src\main.css

1
2
3

@tailwind base;
@tailwind components;
@tailwind utilities;

然后编写 flask app 应用 app.py，使用 flask-assets 打包生成的 js 和 css文件
