[英]Multiple Tailwind CSS classes having multiple Webpack entry points
Problem statement问题陈述
So I have a React project setup with webpack and tailwind CSS.所以我有一个带有 webpack 和 tailwind CSS 的 React 项目设置。
In my webpack config I have multiple entry point in order to generate different CSS and JS for each entry point.在我的 webpack 配置中,我有多个入口点,以便为每个入口点生成不同的 CSS 和 JS。
The problem arises when I use the tailwind classes in my React components.当我在我的 React 组件中使用顺风类时,就会出现问题。
Let's suppose if I use a tailwind class bg-red-600 only in Component1(or entry point 1).假设我仅在 Component1(或入口点 1)中使用顺风类bg-red-600 。
So after building the files through webpack the bg-red-600 will be present in all the entry point's generated CSS files(keep in mind I have just used this class in first entry point component only).因此,通过 webpack 构建文件后, bg-red-600将出现在所有入口点生成的 CSS 文件中(请记住,我只是在第一个入口点组件中使用了这个类)。
What it should be doing is only have bg-red-600 class in first component CSS file instead it is preset in all the CSS files even though I have not used it in any other place other than first component.它应该做的只是在第一个组件 CSS 文件中有bg-red-600类,而不是在所有 CSS 文件中预设它,即使我没有在第一个组件以外的任何其他地方使用它。
Hope I was able to made my point.希望我能够表达我的观点。
Thanks.谢谢。
Webpack's entry points: Webpack 的入口点:
entry: {
app1: path.resolve(
__dirname,
'src/Component1'
),
app2: path.resolve(
__dirname,
'src/Component2'
),
},
Here is my solution:这是我的解决方案:
/config
folder with custom tailwind-xxx.config file for each entry js /config
文件夹,其中包含每个条目 js 的自定义 tailwind-xxx.config 文件eg.例如。
/config/tailwind-ConfirmButton.config.js
: /config/tailwind-ConfirmButton.config.js
:
module.exports = {
content: [
'./src/common/ConfirmButton/ConfirmButton.jsx',
],
// plugins: [require('@tailwindcss/forms')],
}
const postcssOpts = { postcssOptions: env => {
// here is the point
const component = env._module.context.slice(env._module.context.lastIndexOf('/') + 1)
return {
plugins: [
['tailwindcss', {
config: `./config/tailwind-${component}.config.js`,
}],
autoprefixer
]
}
}
}
...
entry: {
confirm: path.resolve(__dirname, './src/widgets/confirmButton.js'),
},
target: ['web', 'es5'], // <=== can be omitted as default is 'web'
output: {
filename: '[name]/tag.js',
path: path.resolve(__dirname, 'dist/exp'),
publicPath: './',
},
...
{
test: /\.css$/,
use: [
{ loader: 'style-loader' },
{ loader: 'css-loader' },
{
loader: 'postcss-loader',
options: postcssOpts,
},
],
},
/src/widgets/customButton.js
: /src/widgets/customButton.js
:...
render(
<ConfirmButton
expId={expId}
content={content}
confirmBtn={confirmBtn}
cancelBtn={cancelBtn}
field={field}
/>,
container
