react 配置使用less后缀文件
//安装less less less-loadernpm install less less-loader --save-dev
安装完成后,在项目中的config目录下找到webpack.config.js文件(说明:新建项目一般默认不显示config目录的,需要执行npm run eject)
//在文件中,找到以下代码const cssRegex = /\.css$/;
const cssModuleRegex = /\.module\.css$/;
const sassRegex = /\.(scss|sass)$/;
const sassModuleRegex = /\.module\.(scss|sass)$/;
//在这里添加less正则
const lessRegex = /\.(less)$/;
const lessModuleRegex = /\.module\.(less)$/;
最后加入如下代码:
{test: lessRegex,
exclude: lessModuleRegex,
use: getStyleLoaders(
{
importLoaders: 2,
sourceMap: isEnvProduction && shouldUseSourceMap,
},
'less-loader'
),
// Don't consider CSS imports dead code even if the
// containing package claims to have no side effects.
// Remove this when webpack adds a warning or an error for this.
// See https://github.com/webpack/webpack/issues/6571
sideEffects: true,
},
// Adds support for CSS Modules, but using SASS
// using the extension .module.scss or .module.sass
{
test: lessModuleRegex,
use: getStyleLoaders(
{
importLoaders: 2,
sourceMap: isEnvProduction && shouldUseSourceMap,
modules: true,
getLocalIdent: getCSSModuleLocalIdent,
},
'less-loader'
),
},
