How To Debug Craco/Webpack

通过 node 的 inspect-brk 参数启动后,node 会自动断点断在 webpack 入口的第一行。这时打开 Chrome,随便一个页面打开 devTools,在左上角会出现一个绿色的 Node.JS 图标(在切换手机显示模式按钮的右边),点击后就会自动连接到 node 的 debug,然后进 source 标签下单步执行就行了 // mac node --inspect-brk ./node_modules/.bin/craco build // windows node --inspect-brk ./node_modules/@craco/craco/dist/bin/craco.js build

craco 修改 output.path

https://github.com/dilanx/craco/issues/104 paths.appBuild = webpackConfig.output.path = path.resolve('custom-build-dir');

customize-cra

customize-cra 真tm坑啊,less-loader,postcss-loader等版本不同容易报错,配置不兼容问题很多

js
addLessLoader({
    lessOptions: {
      javascriptEnabled: true,
    },
  }),
  adjustStyleLoaders(({ use: [, , postcss] }) => {
    const postcssOptions = postcss.options;
    postcss.options = { postcssOptions };
  }),
addLessLoader({
    lessOptions: {
      javascriptEnabled: true,
    },
  }),
  adjustStyleLoaders(({ use: [, , postcss] }) => {
    const postcssOptions = postcss.options;
    postcss.options = { postcssOptions };
  }),
